Description

Need to specify a standard profile for multi-way VoIP/Video calls.

Options include:
- Signalling for all calls is mixed into the same room (useful for multicast traffic)
- Signalling between calls and conference server is in side-channel 1:1 rooms
- We use EDUs of some kind for non-stateful conference signalling

Do we do SFU, MCU, full mesh, multicast, or some combination?

Do we hook into Jitsi or Kurento or Janus or FreeSWITCH or what?

Research direction

Start with the issue's listed alternatives for signalling, conference topology, and integration with Jitsi, Kurento, Janus, or FreeSWITCH. Done would require agreement on a standard multi-way VoIP/video profile and documenting that decision in the Matrix specification.
