I've tried all sorts of debug and parameter changes over the weekend,
but still can't figure out the correct solution.
If I disable timers on the sip profile then all works fine.
<param name="enable-timer" value="false"/>
But that seems like a hack; not a correct solution. With the build
13168M (which is pre the new NAT functionality) everything worked fine.
The SIP trace shows the phones and FreeSWITCH happily exchanging NOTIFY
and "200 OK" messages. Audio's working - just calls timeout after 100
seconds with RECOVERY_ON_TIMER_EXPIRE. Is enforcement of this timer new
functionality - and really just exposing a problem I've always had
before?
The config is (50 Polycom Phones -> NAT -> Internet -> Amazon EC2)
I would really appreciate some pointers on what to look for; additional
trace that might reveal something.
Thanks, Chris.
