Soft Phone -> Asterisk A -> Asterisk B -> Carrier Soft phone is behind a NAT. Asterisk servers are not, same as the carrier. We've noticed that the carrier tries to run a media re-invite, after the call had basically dropped from Asterisk B, and tries to do it over and over again, without stopping. Eventually, that would dead-lock chan_sip completely, requiring a full blown asterisk restart. Any of you ever encountered anything like this? I've mitigated the issue by forcing two different codecs on the two sides of Asterisk B, basically, preventing the media re-invite - but it isn't the proper solution.
I can't say I've heard of anyone running into this problem and it's a common enough scenario. I'd suggest trying against the latest 13 and if not resolved then filing an issue with a description and backtrace.
