The key item in my logs, which would preface the call dropping, was: [2011-06-28 09:43:49] DEBUG[25563] chan_sip.c: ** SIP TIMER: Cancelling retransmit of packet (reply received) Retransid #858
For instance - a call would be connected. SIP debug/core debug on. At the 14:30 mark I would begin tailing the full log. Once I saw the SIP TIMER notice, it would be followed by a new INVITE (re-invite) SIP transmission that would be sent to the phone currently on call. This re-invite was odd in that it would be on a different port to the phone than was already established (for example the NAT outgoing SIP OPTIONS would be sent to the phone on port 27608 - and this re-invite might go out on port 35780). The behavior following would be: Asterisk would hang up as though the parties disconnected - however the phone would show the call was still going and would continue sending SIP responses to asterisk indicating as such. When the phone was manually hung up it would send a SIP BYE (as normal) to asterisk - indicating it had no notice that Asterisk dropped the call. Adding to sip.conf session-timers=refuse Resolved the issue by stopping Asterisk from sending these re-invites during a live call. Hope that helps! I have more SIP debugs/logs if they're useful to ya.

I'm looking into the sip session timers. I believe the issue lies there, but haven't confirmed that just yet. On Jul 1, 2011, at 10:31 AM, Jonathan Thomas wrote: > 900ms?
