The AV1 codec represents the cutting edge of video compression technology. Developed by the Alliance for Open Media (AOMedia), a consortium including tech giants like Google, Microsoft, Netflix, and Mozilla, AV1 is a loyalty-free video codec that was designed to meet the ever-growing demand for high-quality video streaming while minimizing bandwidth usage.
It offers up to 30-50% better compression compared to its predecessors like VP9, VP8 and H.264, enabling sharper visuals at lower bitrates. This makes it an ideal choice for bandwidth-constrained environments, such as mobile networks or rural areas with limited internet speeds. Despite its impressive capabilities, the adoption of AV1 has been slower than anticipated due to several factors. AV1 has higher computational demands as its advanced compression algorithms require significantly more processing power for encoding and decoding. Hardware acceleration for AV1 is still emerging and therefore use of AV1 can result in higher CPU/energy consumption and suboptimal performance on low end devices and those without hardware support.
The path to adding AV1 support in Jitsi was not straightforward. Before we could enable AV1, it was essential to integrate support for the various modes and complexities that the codec offers, both in the Jitsi Meet client and the Jitsi Video Bridge (JVB). Jitsi had to extend JVB’s capabilities to handle AV1 streams, including managing simulcast and SVC modes seamlessly for multi-user conferences. This groundwork laid the foundation for AV1’s eventual inclusion as the preferred codec in Jitsi deployments.
AV1’s RTP encapsulation is unusual, if not weird, compared to RTP payloads for other video codecs – all the information an RTP Selective Forwarding Unit (SFU) like the JVB needs is carried in a “Dependency Descriptor” RTP header extension, rather than in the RTP payload proper. This means that the JVB doesn’t technically need to support the AV1 codec at all – it only needs to support the dependency descriptor header extension.
This format is unusual in that it was developed not in the IETF, where RTP payload formats are normally defined, but rather by AOMedia itself. The main consequence of this is that the header is encoded very much like a video codec: it’s very parsimonious of bit usage, at the cost of being both annoyingly complicated to parse, and being stateful – information needed to parse the header is sent only at intervals. For more information about this complexity, see Lorenzo’s post from several years ago – https://www.meetecho.com/blog/av1-svc/.
Handling the complex parsing is relatively straightforward once some utility classes are written. However, handling the statefulness is harder, especially given that an SFU always needs to be prepared for packet loss and reordering, so packets that use some state may arrive before the packet that provides it. Thus this work needs to keep track of the state that’s reported in those packets that carry it, and pass it forward to the parser to parse subsequent headers, while handling the possibility that a state update may have been missed.
Because the AV1 DD is a header extension, it can be applied to codecs other than AV1 itself. Notably, this allows us to indicate temporal scalability of an H.264 stream, which is useful because H.264 (without its little-implemented SVC extensions) has no way to indicate temporal scalability of its packets. As a result, the work to support the AV1 DD also allows Jitsi to enable scalable H.264 streams for JVB-mediated conferences as well! (Though there are currently some bugs in Chrome that make this less efficient than it could be – see here and here.) In fact the header can be applied to any video codec, though we still prefer to handle VP8 and VP9 using their in-payload information when that information is available.
Another notable feature of the AV1 dependency descriptor is its concept of “decode targets”, which are a specific layer that a decoder can decode, and thus that an SFU can forward. These usually correspond to a specific spatial and temporal layer, but technically they do not have to. The idea is that a decoder can choose among the various decode targets present in the stream. In most cases it would want to choose the highest-quality one available, but in some circumstances (for instance if it was CPU-constrained, or displaying a source in a small window) it could choose a lower-quality target instead.
This has the consequence that a stream needs to be explicit about what decode targets are actually present. An SFU, by design, forwards only some of the layers in a stream; this is what it means to “selectively forward”. As a result, the ultimate decoder needs to know what layers it can actually expect to receive, vs. which ones it won’t receive, or it can end up waiting forever while it never gets the frames it thinks it should render. To handle this case, the AV1 dependency descriptor contains a decode target bitmask in the AV1 header extension to indicate which layers are still present in the stream. This bitmask then needs to be updated every time the SFU changes its layer forwarding decision, so the decoder doesn’t try to wait to decode a decode target that won’t be arriving any more, or, conversely, so it can know to start decoding a new layer that’s newly started arriving. Fortunately, the logic to do this work is not too complicated, and is similar in complexity to the logic needed to modify the in-payload information for forward VP8 or VP9 streams.
With the release of Chromium M111, significant advancements were made in WebRTC, particularly with the introduction of Scalable Video Coding (SVC) support. This update enabled WebRTC applications to configure encoding parameters for SVC by extending the RTCRtpEncodingParameters dictionary. Around the same time, Chrome also introduced AV1 and VP9 simulcast support. Before Chromium M111, the K-SVC mode (Keyframe-scalable video coding) was the only supported mode for SVC. This update allowed Jitsi Meet to experiment with various scalability modes for AV1 and VP9.
In a Jitsi conference, the client and JVB work in tandem to ensure efficient video streaming. This involves an ongoing exchange of sender and receiver video constraints.
This dynamic coordination minimizes bandwidth usage and optimizes network resources while maintaining the quality of the user experience. Once the client receives sender constraints, it configures its outbound video streams using RTCRtpEncodingParameters. These parameters are tailored based on:
For AV1 and VP9, three operating modes were tested:
SVC allows a single video stream to be encoded in layers, each layer adding more detail or resolution to the base stream while simulcast involves sending multiple independent video streams of the same content, each at a different resolution and bitrate.
| Aspect | Simulcast | SVC |
Encoding |
Multiple streams encoded separately. |
One stream encoded with multiple layers. |
Bandwidth Usage (Sender) |
Higher (multiple streams). |
Lower (single stream). |
CPU Usage (Sender) |
High (due to multiple encodings). |
Lower (single encoding with layers). |
CPU Usage (Receiver) |
Lower (no need to decode layers). |
Higher (decoding layered streams). |
| Adaptability | Coarser (switching between streams). |
Finer (dynamic layer adjustment). |
Compatibility |
Broadly supported in WebRTC platforms. |
Limited support, requires advanced codecs. |
After extensive performance testing and careful evaluation of product requirements, Jitsi selected full SVC mode as the default configuration for both AV1 and VP9. This choice ensures optimal scalability and video quality across Jitsi’s deployments. However, this behavior is not rigid; it is configurable and can be easily overridden through config.js settings, providing flexibility to adapt to specific use cases or deployment needs.
To determine the optimal video codec for use in the Jitsi Meet client, Jitsi conducted comprehensive testing under realistic conditions to ensure that codec selection would meet product needs for quality, performance, and scalability. Below is an overview of the methodologies and considerations involved:
By rigorously analyzing these metrics, Jitsi optimized its codec selection strategy. While Full SVC modes remained the default for high-performance scenarios, fallback options like VP9 and VP8 were configured for legacy or resource-constrained devices. This comprehensive approach ensures that the Jitsi Meet client provides the best possible video experience across a wide range of devices and network conditions.
With the integration of AV1 into Jitsi Meet, users benefit from superior compression and high-quality video at lower bitrates. However, these advantages come at the cost of increased computational demands, especially on low-end devices. To address this, Jitsi introduced a three-fold adaptive quality control mechanism, ensuring a seamless experience even under CPU constraints.
This adaptive approach enables Jitsi Meet to leverage the advanced capabilities of AV1 while ensuring that users with diverse hardware configurations can participate in meetings without disruptions caused by excessive CPU usage.
However, when the CPU spike originates from an external process rather than the Jitsi Meet client, the adaptive mode ensures that quality degradation is minimal. To enhance the user experience, Jitsi Meet also incorporates a recovery mechanism that restores the video configuration once the external constraints are resolved.
This gradual approach minimizes the risk of overloading the system during recovery. It also adapts to fluctuating CPU availability, maintaining a balance between performance and quality. The client handles this entire process dynamically without any user interaction, providing a seamless experience.
Firefox and Safari do not advertise support for the AV1 codec yet. As a result, when users on these browsers join a call, all other participants automatically switch to the next codec in the preferred list, ensuring compatibility across all endpoints.
Additionally, while Chromium-based mobile endpoints are capable of both encoding and decoding AV1, Jitsi has opted to use AV1 only for decoding. For encoding, a lower-complexity codec is used, as encoding typically imposes a higher CPU load compared to decoding. This decision balances performance and device resource constraints, especially on mobile devices.
We have great news for you then!! AV1 support was introduced to Jitsi in June 2024 and has been available in our stable packages ever since. Initially, AV1 had to be manually configured as the preferred codec through config.js settings, allowing users to opt in.
Building on this, AV1 was soon made the preferred codec on meet.jit.si, marking a significant step in leveraging its advanced compression capabilities. Starting with release stable-9909, AV1 became the default preferred codec in our Docker deployments, ensuring out-of-the-box support for users opting for containerized setups.
After thorough experimentation and analysis of real-world performance data, we’re excited to share that AV1 will very soon become the default preferred codec in all deployments, bringing its exceptional bandwidth efficiency and video quality to a broader audience. Stay tuned!

In the last stable release, Jitsi enabled a new feature called SSRC rewriting that improves the system performance for very large calls. This feature helps reduce the overall load on the system by reducing the number of signaling messages that get exchanged during a large call involving hundreds of endpoints. It also reduces the load on the local endpoint drastically by restricting the number of audio and video decoders created by the WebRTC engine thereby offering a better user experience for large calls.
When this feature is enabled, only a fixed set (let’s say up to 50) of SSRCs are signaled to the downstream endpoints in the call irrespective of the call size. An SSRC is nothing but a unique ID used for identifying a stream of RTP packets that belong to an audio or a video source. When additional media sources are requested by the receiver, the Jitsi Videobridge (JVB) overwrites the SSRCs of the newly requested media streams with that of the ones that were already signaled to the client before and are no longer needed. Therefore, no more than 50 SSRCs need to be signaled to the endpoints even if the number of media sources that will be routed in total far exceeds the set limit.
Moving on to the why – what is the problem that we were trying to solve by implementing SSRC rewriting?
The challenges that we faced when adding support for very large calls with respect to source signaling with the existing approach of signaling every new source to every other participant in the call were two fold.
At the client level, the number of m-lines in the SDP grew linearly with every remote source that got added to the call irrespective of whether media for that particular source gets routed to the endpoint or not. When a new m-line with SSRC is added to the remote SDP, the libwebrtc engine creates a transceiver and does all the plumbing necessary to decode a media stream with the given SSRC if and when it starts receiving it from the JVB. This tied up resources on the local endpoint unnecessarily and introduced delays in renegotiation cycles which resulted in unpleasant user experience. The client can also hit transceiver and SDP parser limits imposed by the browser resulting in unexpected behaviors. These performance issues are more pronounced on mobile endpoints which have fewer resources to begin with compared to the endpoints running on desktops.
On the backend, as the number of participants grew, so did the number of audio and video sources that needed to be signaled to every other participant in the call. This made the signaling traffic from prosody (XMPP communication server) to the endpoints grow quadratically. This was a problem, because Prosody, which is single-threaded, was already the bottleneck when scaling calls. Previously we had to introduce artificial delays in signaling in order to reduce the load. This caused long delays for the media to be established across participants when they unmuted their audio or video for the first time and was very disruptive to large meetings.
The solution to both of these problems was to switch to a demand based signaling mechanism where only a limited number of remote audio and video tracks are signaled to the endpoints depending on what is being needed or requested by them in real time instead of signaling all the known media sources in the call as and when they get added to the call.
Jitsi Videobridge (JVB) uses a slightly different approach for audio and for video when determining what sources to forward. Forwarding decisions for audio are based simply on the “loudness” of the streams determined from the audio level RTP extension.
With SSRC rewriting, JVB uses a separate SSRC space for each receiver. It maintains a map from an SSRC number to the name of a source. Changes to the map are signaled to the receiver over the direct signaling channel (a WebRTC DataChannel over SCTP), using partial updates:
[modules/RTC/BridgeChannel.js] <e.onmessage>: Received AudioSourcesMap: [{"source":"fc63db0f-a0","owner":"fc63db0f","ssrc":2602882473},{"source":"449360a0-a0","owner":"449360a0","ssrc":1358697798}]
[modules/RTC/BridgeChannel.js] <e.onmessage>: Received VideoSourcesMap: [{"source":"e01f2103-v0","owner":"e01f2103","ssrc":3129389873,"rtx":3219602897,"videoType":"CAMERA"},{"source":"9ac8fef2-v0","owner":"9ac8fef2","ssrc":1542056973,"rtx":1571329554,"videoType":"CAMERA"},{"source":"ed6b60f5-v0","owner":"ed6b60f5","ssrc":550523896,"rtx":2808127984,"videoType":"CAMERA"}]When a new stream needs to be forwarded, it is allocated an SSRC. Before the limit is reached, JVB simply generates a new SSRC number, and when the limit has been reached the oldest entry is reused. Let’s look at an example to make this more clear. Assume the limit is set to just 3, and the available sources are A, B, C, D, E. Initially the map is empty. When A starts sending packets, we allocate SSRC 101 to it and signal it to the receiver like this:
AudioSourcesMap: [{"source":"A","owner":"endpoint-A","ssrc":101}]Similarly when B and C start to speak we allocate SSRCs 102 and 103 for them:
AudioSourcesMap: [{"source":"B","owner":"endpoint-B","ssrc":102}]AudioSourcesMap: [{"source":"C","owner":"endpoint-C","ssrc":103}]Now we have reached the limit of 3 SSRCs. When D starts to speak, we’ll find the source in the map that has been active least recently (let’s say that’s B) and re-use its SSRC for D. We’ll signal an update (“SSRC 102 now belongs to D”):
AudioSourcesMap: [{"source":"D","owner":"endpoint-D","ssrc":102}]The scheme is identical for video, except the forwarding decisions are made in a different way. Receivers explicitly signal their preferences using video constraints. The source names and their mute status are published in presence when an endpoint signals its source information to the Jitsi Conference Focus (Jicofo) and therefore this information is already available with all the other endpoints in the call. Based on the current layout in the UI and the user’s preferences, the client sends the updated receiver video constraints over the bridge channel.
A bandwidth allocation algorithm in the JVB then decides which streams to forward to a particular receiver, based on its constraints and current network conditions:
[modules/RTC/BridgeChannel.js] <Fa.sendReceiverVideoConstraintsMessage>: Sending ReceiverVideoConstraints with {"constraints":{"ed6b60f5-v0":{"maxHeight":360},"e01f2103-v0":{"maxHeight":360},"9ac8fef2-v0":{"maxHeight":360}},"defaultConstraints":{"maxHeight":0},"lastN":-1,"onStageSources":[],"selectedSources":[]}On receiving an update to one of the maps (audio or video), the client adds the signaled SSRCs to the remote description on the peerconnection. The browser then fires a track event for each of the SSRCs, the corresponding remote tracks are then added to the HTMLElements associated with the remote user.
So when the audio packets with this SSRC arrive, the browser starts decoding the media and plays it through the selected audio output device. If the SSRC is already in use (i.e. the limit on the bridge has been reached) the client updates the owner of the associated track so that it gets attached to the corresponding HTMLAudioElement and the audio switches over to the new speaker seamlessly.
The video track creation process is the same as that of the audio tracks as described above. The client application needs to update the track’s owner whenever there is an updated source map involving the SSRC that is assigned to the track and re-attach it to the corresponding HTMLVideoElement so that the correct video stream is rendered in the remote participant’s viewport.
But wait, re-using an SSRC like this is okay for audio because the streams simply get mixed before playback, but what about video, how do we avoid video content being rendered in the wrong viewport when signaling and media race? That’s the elegance of this approach, we simply use a large enough limit (larger than the maximum number of streams forwarded at any one time) and the occurrence becomes extremely unlikely. If the limit is larger by K, then K new forwarding decisions must be made before the signaling arrives at the receiver for the problem to happen.
So how do we choose the limits? We have the constraint just mentioned, but also an interesting trade-off. If the limit is too high we’re using unnecessary resources at the receivers. But if the limit is too low, we’ll be signaling updates more often. We have chosen to set the limits to 50 by default. That’s 50 for audio and 50 for video, which is well above the maximum of 25 tiles that we display at any time.
When SSRC rewriting is enabled, the number of source signaling messages can increase drastically based on the SSRC limits set for the conference and the total number of participants in the call. Imagine a call with 100 participants where everyone has their video on; UI shows a grid of 25 participants and the SSRC limit is set to 25. Whenever the user scrolls to the next grid of 25 participants, existing SSRCs get remapped. This happens everytime the user scrolls back and forth. This results in a lot of signaling messages over the bridge channel. What if the websocket connection for the bridge channel is down at this time? This would result in videos not being rendered or audio from new dominant speakers not being heard which can be very disruptive to meetings. All the sources are signaled immediately after the websocket connection reforms but even minimal disruptions to audio can be very annoying.
To mitigate these issues, Jitsi client switches to using WebRTC’s SCTP data channel for establishing the bridge channel instead of using a websocket. This ensures that the bridge channel is up and running all the time as long as the media connection between the client and the JVB is up. This results in minimal or no disruptions to the signaling messages from the JVB to the downstream endpoints.
This feature has been well tested and has been running on meet.jit.si for the past few months now, with limits set to 50. We also enabled it by default in our last stable release of the Debian packages and Docker images. We will be releasing it soon to all our production deployments in the next few releases pending investigation into some SCTP crashes that we are seeing in the JVB .

So you want to have live meetings in Moodle courses. Well, as it turns out, this is quite an easy feat. Thanks to the wonderful work done by UDIMA (Universidad a Distancia de Madrid), you can use their Jitsi Moodle Plugin.
If your use-case doesn’t go beyond 25 monthly individual endpoints, you might want to opt for the JaaS Dev offering which is completely free. For users requiring more than 25 monthly endpoints or desiring premium features like transcriptions, dial-in, recordings or RTMP streaming, there are two options:
1. Add a credit card for overages, paying extra costs as needed, without any discounts.
2. Sign up for alternative plans offering an initial discount of 80% off for the first three months of JaaS usage.
To benefit of the 80% discount you need to use the MOODLE23 JaaS Coupon. The coupon expires on September 2024.
Before starting the configuration process, you need to download and install the latest Jitsi Moodle Plugin in your Moodle instance and create a JaaS account.
Right off the bat, the plugin tries to use the freely accessible meet.jit.si instance as the backend. This is only going to work for the first five minutes due to the changes announced here. This should be more than enough if you only want to give it a try.
Once you have created your JaaS Account, here are the steps to configure the plugin:
Go to the JaaS API Keys section and create a new key pair. Name it something meaningful. Download the private key and store it somewhere safe.
Open the Moodle Jitsi plugin settings and change the values as follows:
– Domain: `8×8.vc`
– Server type: pick `8×8 Servers`
– App_ID: copy it from the JaaS Console API Keys page, i.e. `vpaas-magic-cookie-xxxxx`
– Api Key ID: copy it from the keys table in the same page, it should be something like `vpaas-magic-cookie-xxxxx/somehex`
– Private key: the contents of the private key you just downloaded from JaaS Console
– Make sure to leave the ID User (jitsi_id) dropdown to Username, the default
With just a few steps, you’ll now have a complete communication solution right within Moodle!

There was a time when cash was king. Today, however, not so much.
Paying over the phone for everything from fast food to a holiday abroad has become the norm for millions of consumers who prioritise modern convenience over traditional transacting.
Protection from fraud is, of course, paramount, which is why strict rules exist. Phones used by businesses to take payments must be Payment Card Industry-compliant. They must feature ‘pause-and-resume’ functionality for use at the critical point that customers provide their payment card details. Also, all transactional calls and call recordings must be encrypted.
Breaching these rules can lead to seriously big fines capable of dealing a catastrophic blow to profit and reputation. Ultimately, in the most extreme cases, non-compliance can even lead to jail!
Next year, the rules change: an update to the Payment Card Industry Data Security Standard (PCI DDS) which beefs-up protection, but which also places new obligations on in-scope organisations. In a world in which technology plays a vital part in the way over-the-phone transactions occur, it is the perfect time for businesses and their Managed Service Providers to also change things up – upgrading desk and softphones that support that all-important compliance.
Choose Sangoma’s award-nominated P-Series Desk and Softphone, and that-all important compliance also comes with a feature set that ensures the wider desk calling experience is rich and rewarding for both callers and agents. High-definition audio, unprecedented plug-and-play deployment, and advanced IP applications as standard that include voicemail, call log, contacts, phone status, user presence, call parking, and more. Big and bold, yet at the same time stylish and sleek, its ergonomic design leverages the beauty of angles, curves and corners to provide users with brilliant visibility of and access to its bright touchscreen display and lightweight receiver, regardless of where they sit or stand. The audio is crisp and clear, the management and compliance of calls is fast and effective, and overall satisfaction levels are high. For callers, that overall high-quality reflects favourably on the brands or organisations with which they interact.
Importantly, the P-Series’ versatile compatibility with both PBX and cloud-based voice systems also means it can be deployed on different platforms in different spaces whilst maintaining an organisation’s look-and-feel. In addition, the P-Series is the only Desk Phone designed to be fully-compatible with Sangoma’s wider communications portfolio – further enhancing its value to Sangoma customers and enabling its commercial reseller partners to benefit from the efficiency and simplicity of stocking and supporting just one Sangoma phone product line. The P-Series brings yet more added value too. The rarest of combinations: it appeals to all types of user groups, at a price point that suits all types of budgets.
For user organisations and their MSPs, we think that makes for a compelling offer all-round.

It’s hard to believe that Asterisk has been around for 25 years. It started in humble beginnings as a phone system for a fledgling company, only to grow and expand to become the purpose of that company itself eventually. While I was not there from the beginning, I was there from the fairly early days.
Back then, it was the wild west. VoIP was still new. SIP was still new, and its problems had yet to be discovered. STIR/SHAKEN was in the minds of no one. The cost of calling people was still high (in comparison to what we pay today). Asterisk swiftly emerged onto the scene and became THE open source phone system. It disrupted the traditional phone system market and gave the power back to the users and deployers to do things the way they wanted at a price they could handle.
As the industry evolved and expanded, Asterisk continued to do so as well. Thanks to the numerous contributions and the community around the project, it expanded in functionality and scope beyond what anyone could have envisioned. Its usage grew and grew in more clever and interesting ways. Every week, by helping individuals and talking to them, I find new ways that Asterisk is used. The flexibility of Asterisk means you are always surprised by what people are doing.
This evolution and expansion continue to happen to this day. While Asterisk started as a phone system, it has also become a telephony toolkit. This has given users even more power and control, especially developers, allowing them to manifest ideas more rapidly in the communications space by providing easy-to-use and understandable interfaces. This is where a lot of the power in Asterisk is these days. This aspect is filled with endless possibilities and untapped potential.
I want to thank everyone who has helped Asterisk get to this point. Those who have contributed code or ideas, filed issues, helped others on forums and other places, and spread the word of Asterisk itself. It’s been a wild 25 years, and we still have more to go. It’s not too late to join me and others on the journey through participating in the Asterisk project and community. You can find us on GitHub or the Community Forums. All help is welcome!
As always, I enjoy sharing extra resources. If you’re intrigued by the history of Asterisk and other related topics, I invite you to check out the webinar I gave on the fascinating “Evolution of Asterisk”.

With the holidays just around the corner we thought it would be a cool to show a perhaps non-conventional use of the Elgato StreamDeck, a gadget I recently acquired that would make a great gift!
The Elgato Stream Deck is a programmable hardware device that allows users to automate virtually any task with the press of a button. It has been around for a while but not too long ago I was at the RTC.ON conference chatting with my buddy Dan Jenkins when he told me there was a library to control these devices using WebHID. I instantly bought one (no, this is not a sponsored post).
The idea here is to use the Jitsi iframe API (you can start using it right away with a free JaaS account!) to map custom meeting controls on your own Stream Deck. Our iframe API provides a bunch of events and commands to interact with the meeting and the WebHID library allows us to program each key individually, inluding the icon on each of the buttons, which is actually a tiny display!
Here is a video demonstrating the integration:
Cool, right! The potential for contextual controls for specific applications right from your browser is virtually boundless, what a time to be working on the Web Platform.
The source code can be found here. It works with 6 buttons by default (the Stream Deck Mini) but it’s easy to adapt to other models.
Have fun and happy holidays!
Your personal meetings team.

Starting on August 24th, we will no longer support the anonymous creation of rooms on meet.jit.si, and will require the use of an account (we will be supporting Google, GitHub and Facebook for starters but may modify the list later on). This is a first for us, so users may encounter a few bumps here and there as we are tweaking the experience to make sure there is as little friction as possible on the way into a meeting.
When we started the service back in 2013, our goal was to offer a meeting experience with as little friction and as much privacy as possible. We felt and still feel that both of these goals are very important and one of the main reasons that justified the existence of “yet another meeting service.” We wanted people to be able to converse easily and freely, without fear of expressing their views and opinions.
Our “one tap and you’re in” experience was a big part of our strategy to eliminate friction. We didn’t want people to have to worry about “creating” meetings in advance, remembering passwords, codes or long complicated sequences of numbers for a meeting ID. We wanted users to be able to think of a name and just go there. Through the years we’ve had to compromise on this a little bit. We ended up introducing a pre-meeting device check screen. We felt that checking your camera and microphone before you entered a room could save everyone some hassle so it was worth the pause.
As for privacy, we previously made sure all communication was always encrypted and we retained no data beyond what is necessary to actually provide a decent meeting service.
Offering the possibility to anonymously use the service felt like a good way to help with both its privacy and the usability.
Our commitment to both goals remains as strong as ever but anonymity is no longer going to be one of the tools we use to achieve them.
Earlier this year we saw an increase in the number of reports we received about some people using our service in ways that we cannot tolerate. To be more clear, this was not about some people merely saying things that others disliked.
Over the past several months we tried multiple strategies in order to end the violations of our terms of service. However in the end, we determined that requiring authentication was a necessary step to continue operating meet.jit.si.
It is a good time to have a look at our privacy terms. 8×8 will now store the account responsible for creating rooms. Aside from the changes to our privacy terms referenced above, there is no other change to our meetings. We are still very much committed to holding user privacy in the highest regard and we still have no tools that would allow us to compromise the privacy of the actual audio or video content of a meeting, nor do we intend to create any.
That said, it is completely understandable that some users may feel uncomfortable using an account to access the service. For such cases we strongly recommend hosting your own deployment of Jitsi Meet. We spend a lot of effort to keep that a very simple process and this has always been the mode of use that gives people the highest degree of privacy.
If you see content that violates the jit.si terms of service you can always report it.
That’s all we’ve got for now!

Flutter‘s initial release occurred in 2017, the same year as the introduction of our mobile apps and mobile SDKs. For those who are unfamiliar with it, Flutter is one of the most popular frameworks for developing cross-platform applications.
Now a few years after their first release, we are thrilled to announce that our mobile SDKs and Flutter cross paths as the Jitsi Meet Flutter SDK. Yes that’s right, after multiple requests, an official Jitsi Meet Plugin for Flutter is now available.
As of now, our family of mobile SDKs is more complete than ever.
Android and iOS are supported, of course. The plugin serves as a wrapper for the iOS and Android SDKs, on top of which a Flutter API was created with functionality similar to those found in native APIs.
The plugin is available on pub.dev under the jitsi_meet_flutter_sdk name. Discover it there, follow the instructions, and you’ll be able to utilize the API to the fullest extent.
Here is a sneak peek of how simple it is to add a meeting to a fresh page.
Here is how that looks like:
In your own Flutter app, you’ll have the same view as the one from the Jitsi Meet mobile apps, with just a few additional lines of code, amazing, right?
We developed two apps using the Jitsi Meet Flutter SDK, one of which is the example app in the plugin repository and primarily acts as a tester app by displaying the majority of the plugin’s features in the user interface, and the other of which is an official sample app in the repository that contains all of our samples for all mobile SDKs and is just a straightforward example of integrating Jitsi Meet.
Flutter is new to us, and we hope this new SDK will make it easier for our users and JaaS customers to embed video meetings into their existing Flutter apps we agerly await your feedback!

Ever since we introduced our mobile apps to the world back in 2017 they have been backed by React Native.
Using React Native allowed us to reach feature parity quickly since all logic is shared between our web and mobile codebases, because they are not 2 different things, it’s a single codebase 
Later that year, we released our native mobile SDKs to the world. These SDKs werer a thin wrapper over our React Native application, so our users could embed the entire meeting experience into their own mobile apps, with little effort.
This has been our guiding priciple since the inception of the iframe API: to privide a high-level and fully-featured component that can be integrated into other apps.
Today we are taking another step in our mobile jouney by releasing a React Native SDK.
What does this mean? Before today if you had a React Native application we provided you with no way for embedding Jitsi Meet. Now we do!
As mentioned above, our mobile apps are built using React Native and over time we received a number of requests from our community and customers to have an actual React Native SDK. We finally managed to expose it as a React Native library. It’s not that we didn’t have it in the back of our minds, but we focused on native first to cater the needs of our internal consumers.
Exposing a React Native app as a component seems easy on the surface, but being so complex and having so many dependencies made it a lot harder han we had thought. Fortunately, this all changed thanks to Google Summer of Code. We were fortunate to have Filip Rejmus take on the project and kickstart it. After his amazing work, we took over and added the final touches and now it’s available on npm.
First go and grab our package from npm and follow the setup instructions.
In the screenshot below you can see how easy it is to integrate and enable different meeting options into your app, by simply importing the JitsiMeeting component and adding it to your code:
You will have access to the same features as the Jitsi Meet app.
We created a sample app which integrates our brand new SDK together with react-native-navigation, check it out!
This new SDK will make it easier for our users and JaaS customers to embed video meetings into their existing React Native apps, we agerly await your feedback!
Your personal meetings team.

In 2017, Jason A. Donenfeld (known for WireGuard®) reported an issue in Tox’s handshake [1]. This issue is called “Key Compromise Impersonation” (KCI). I will try to explain the issue as simple as possible:
In Tox you don’t register an account (e.g. with username and password), but instead your identity is solely based on (asymmetric) cryptographic information, a so-called asymmetric key pair. Such a key pair consists of a public part (public key) and a private part (private key). The public part, as the naming suggests, is public and contained in your ToxID which you share with your contacts to be able to communicate with them via Tox. The private part, again as the name suggests, needs to stay private! If someone gets in possession of your private key, they stole your Tox identity. This could, for example, be the case if someone got physical access to your computer or successfully installed malware on your system, e.g. a so-called trojan horse, to be able to extract data from it. If this happens, you will most likely have multiple problems and your Tox identity may be just one of them. The password you enter when you create your Tox profile, e.g. when you first start qTox client, is used to encrypt your profile and also your private key on your disk. If you start qTox, you need to enter your password to decrypt your private key, to be able to communicate via Tox. Your private key is then stored unencrypted in memory (i.e. RAM) while qTox is running. This means an attacker either needs to get access to your password (steal or crack it) or to read your Tox private key from memory while your Tox chat client is running.
If someone successfully stole your Tox identity (i.e. this private key), they are you – at least in the context of Tox. So they can successfully impersonate you in Tox. Now in this case the KCI vulnerability leads to “interesting” behavior. It is clear that someone who stole your identity is able to impersonate you. But because of the KCI vulnerability, they may also be able to impersonate others to you. This means, to exploit this vulnerability in practice, someone not only needs to successfully steal your private key, but additionally:
In summary, KCI is exploitable, but with a huge effort.
Anyway, this is a real vulnerability and it should be fixed. The current Tox handshake implementation is not state-of-the-art in cryptography and it also breaks the “do not roll your own crypto” principle. As a solution, there is a framework called Noise Protocol Framework (Noise, [2]) which can be used to create a new handshake for Tox. More precisely, the application of Noise will only change a part of Tox handshake — the so-called Authenticated Key Exchange (AKE). Noise-based protocols are already in use in e.g. WhatsApp, which uses it for encrypted client-to-server communication, and WireGuard®, which uses it for establishing Virtual Private Network (VPN) connections. Noise protocols can be used to implement End-to-End Encryption (E2EE) with (perfect) forward secrecy (which is also the case with the current Tox implementation), but further adds KCI-resilience to Tox.
Tobi (goldroom on GitHub) wrote his master’s thesis (“Adopting the Noise Key Exchange in Tox“) on the KCI issue in Tox, designed a new Handshake for Tox based on NoiseIK and implemented a proof-of-concept (PoC) for this new NoiseIK-based handshake by using Noise-C [3]. This PoC has a few drawbacks, which is why it should not be used in practice (see Appendix). If you want to know more about his master’s thesis, see the update in the initial KCI GitHub issue [4].
He applied for funding at NLnet foundation and their NGI Assure fund to continue his work on Tox and to be able to implement a production-ready Noise-based handshake for toxcore. Fortunately, this application was successful [5]. NGI Assure is made possible with financial support from the European Commission’s Next Generation Internet programme (https://ngi.eu/).
The objective of this project is to implement a new KCI-resistant handshake based on NoiseIK in c-toxcore, which is backwards compatible to the current KCI-vulnerable handshake to enable interoperability and smooth transition. The main part of this project is to implement NoiseIK directly in c-toxcore to remove Noise-C as a dependency (as the only other dependency for c-toxcore is NaCl/libsodium) which was used in the PoC and therefore improve maintainability of c-toxcore (see Appendix).
The tasks in this project are:
Noise_IK_25519_ChaChaPoly_SHA512, but it may change due to new insights in c-toxcore).The plan is to implement this new handshake until July 2023. Since it’s not a trivial task, there are still some obstacles:
“Note that lossy and out-of-order message delivery introduces many other concerns (including out-of-order handshake messages and denial of service risks) which are outside the scope of this document.” (cf. [6])
Both points are not ideal for a handshake based on NoiseIK (i.e. it would be way easier to implement it in a client-server model using TCP), but it should be possible to work this out.
Tobi is available in #toktok (libera.chat) as tobi/@tobi_fh:matrix.org and ready for any input, questions, remarks, discussions or complaints.
The PoC shouldn’t be used in practice/in production because it should be improved in the following aspects (for details see chapter five of Tobi’s thesis [4]):
Noise_IK_25519_ChaChaPoly_SHA512 protocol will be implemented directly in c-toxcore. This will remove Noise-C as a dependency for toxcore (i.e. the only other dependency is NaCl/libsodium) and therefore improve maintainability. Additionally this will reduce the number of possibly vulnerable source lines of code.

Hey there Fellow Jitsters!
Have you ever considered adding telephony to your Jitsi Meet self-hosted instance?
Up until now you only had the option to run Jigasi and deal with telephony yourself. Many of our users do this every day, but when we asked we learned that there was interest in offloading that part. Could someone else host it?
Today we’re launching a new way to quickly connect to the public telephone network and offer dial-in capabilities to your users without the need for hosting and managing the entire telephony infrastructure: JaaS components. You can give it a try today!
Are you running Jitsi Meet on a Debian instance or are you using Docker? Either way, you can opt-in for this feature and it will be automatically set up. A new JaaS account will be created for you and you’re good to… call.
If you’re running Jitsi Meet on Debian all you need to do is to answer ‘Yes’ to this question and you will have dial-in capability on your Jitsi instance.
Note: A Let’s Encrypt certificate is required and the email address used to generate the certificate will be used also for creating your new JaaS account.
If you’re running Jitsi Meet on Docker you’ll need to set the following variables on your .env file:
Now you can restart your setup with `docker-compose up –force-recreate`
An email will be sent to you, asking you to set up a password for the JaaS admin account:
From the JaaS admin console you can manage your account, see the overall activity and upgrade to another plan if needed.
You’re all set up now! Let’s make a phone call! Join a call on your Jitsi Meet instance and notice how the dial-in option becomes available when trying to invite participants. You can now dial-in to one of the phone numbers provided in the list and you’ll be connected to the meeting.
Get started today, a free trial is available! Please check the JaaS components website for details on pricing.
Jigasi is the first Jitsi component offered as a service, with more to come. Stay tuned!
Your personal meetings team.
