[asterisk-bugs] [JIRA] (ASTERISK-24600) IAX hangs

[Rusty Newton (JIRA)]

Rusty Newton commented on ASTERISK-24600:
-----------------------------------------

Can we get the iax.conf for both servers and the dialplan used to dial across?

You might see if you can reproduce it by generating calls over the IAX trunk without SIP involved. Say, callfiles, or originations.

> Setup:
> 20 endpoints, register locally over SIP (no NAT)
> 1 IAX trunk to another remote Asterisk box (unauthenticated, IP restricted on firewalls)
> Server randomly gets 2 IAX channels "stuck" (most likely after the call has ended since we haven't had complaints of dropped calls), stops responding to IAX, SIP registrations, etc. High CPU usage on 2 threads (see attached).
> Issue seems to be happening randomly with calls over trunk (SIP to IAX and IAX to SIP). I can reproduce it by simply creating lots of channels over the trunk (it's not rare, but more channels just means I get the issue to happen sooner, not a load issue). Happens every few dozen calls made by the client (about daily since this is a small office).
> Our next steps will be to configure a SIP trunk between sites to isolate if the issue is IAX specific.
