And the shortcut is added:

Then, if C disappears off the network, then B would know it (via the
usual mechanisms, PING/PONG, etc), and would be able to notify A (and
vice-versa). It seems like something to test in practice, though.
I don't know enough about IAX2 to know whether this is true or not...
under what circumstances are PING frames generated at all? They
certainly aren't mini frames, so I can't see how A would ever send one
directly to C.
This is a valid concern... unless B (the machine in the middle) is
sending PINGs to C and will notice that it has disappeared, then kill
entire bridge.
chan_iax2 and all IAX2 implementations send PING every few seconds; 10
to 60 seconds or so, depending on the implementation. chan_iax2 also
sends these LAGRQ things, but they're pretty useless, and really ought
to go.
