Signal now supports free end-to-end encrypted video calls with up to 5 participants
The Signal secure messaging client has added free, end-to-end encrypted group voice and video calls that support up to 5 simultaneous participants.
Announced via the Signal blog, group calling on the secure messenger was built using the RingRTC-powered Signal Private Group System, ensuring that every message and audio or video call is completely private and encrypted end-to-end.
When looking at an open group chat in Signal, you will now see a video call button at the top of the screen. Starting a call in the group sends a notification to all of its members. The group call interface defaults to a grid-based view of every participant, with the option to switch to a view that automatically focuses on the active speaker in the call.
The Signal development team is looking into allowing more than 5 people in a group call "soon." In the meantime, groups created before support for video calls launched, referred to as "legacy Signal groups," will need to be upgraded to "new style Signal groups" in order to use the group video calling feature. This is expected to automatically occur "in the coming weeks."
Signal is now available across Android, iOS, Windows, macOS, and Linux via signal.org/download/.
