WhatsApp Rival Signal has announced that it can now support group video calls with up to 40 participants. The company disclosed about this update through a post on Twitter. “Signal now supports 40 person group calls. Building large end-to-end encrypted group calls requires some new engineering.” The tweet read from the official Twitter handle of Signal. Till now, the platform only supported group calls with up to five participants.
In a blog post, the company has revealed that it uses selective forwarding units, or SFUs, to make this possible since Signal released end-to-end encrypted group calls a year ago. In this method, each participant sends their media to a server, according to Signal. The server “forwards” the media to other participants without viewing or changing it. It works with multiple participants, and is compatible with end-to-end encryption.
