Constant on-peer-error-peer-unavailable errors

[TerminalStar]

There are 3 of us in the call (say A, B and C), A can see and hear B and C; B can only see and hear A; and C can also only see A.

The dev console repeatedly throws on-peer-error-peer-unavailable errors for persons B/C (presumably as it retries the connection to the peer you can't see/hear).
