What happens if the invite never arrives (e.g. federation/networking/implementation bug)? Should we specify a lifetime in m.call.replaces as well or should we just advise clients to stop waiting after a "reasonable" amount of time?

Hmm - a lifetime field feels more like the time that specific event is valid for (eg. if an invite exceeds its lifetime after you've sent an answer but before the call's connected, you'd continue with the call). Feels OK to let clients decide how long to wait, although we might need to add a way for the transferee to say, "I tried, but it didn't work".

"Breakout rooms" are becoming a more and more requested feature thanks to COVID and how useful they are in Zoom and BBB. I continue to wonder if it would be better to have a generic "please take this room somewhere else" mechanism rather than having it VoIP specific. What are the specific VoIP semantics that justify making this VoIP specific?

Mostly that we specify call IDs for the call to create or wait for, plus party IDs.
Sends an m.call.replaces event and flag for whether to advertise support. MSC2747 (matrix-org/matrix-spec-proposals#2747)
Adapt the InviteDialog to select a transfer target Doesn't support supplying a roo mID fr the transfer: just leaves the transferee to work out how to contact the target themselves. MSC2747 (matrix-org/matrix-spec-proposals#2747) Requires matrix-org/matrix-js-sdk#1558

| * `target_room`: Optional. If specified, the transferee client waits for an invite | ||
| to this room and joins it (possibly waiting for user confirmation) and then continues | ||
| the transfer in this room. If absent, the transferee contacts the Matrix User ID | ||
| given in the `target_user` field in a room of its choosing. |

A room may not always be joinable by ID, i.e. if the room was created on a server, that doesn't exist anymore. In general, I don't think you should join a room by the server part from the ID. I suggest adding an additional via field here, so that the room will be joined via one of the servers in that list. You should probably put the server of the target user there. Alternatively, the server to join via could be extracted from the target users mxid.
If this is not present and the users don't share a room, should a new one be created? Then you probably need to wait for them to join the room to send the call events?

Yep - hence them having to wait for an invite to the room. There shouldn't be any need to wait for them to join the room before calling: in fact in future we'll probably need to include metadata in the invite to say the inviter is trying to call, so the invitee has some way of knowing someone's trying to call them, which right now they don't.

Oh, right, I missed that part, my bad, sorry about the noise :D
