almost exactly 5 min.
Two different firewalls, one sonicwall, with all the SIP helpers turned
off, the other, a pfsense firewall that uses Tony's templates.
EVERYTHING ELSE WORKS. I have have hours long conversations if you call
me, or I call you on PSTN (using sip trunks)
sip dialing outbound (including ISN dialing, which uses SIP), almost
EXACTLY 5 mins, audio both ways stops.
(want traces? ok) but this sounds like a common enough thing.
I am ASSUMING this has to do with one of the firewalls timing out after
not seeing something on TCP port 5060 for 5 mins, and that sipxbridge
takes care of this in ITSP configs with keepalive timers.
I tried (in poly 650(=) keepalive.sessionTimers didn't help.
I see (in poly) keepalive interval, but that looks like its for natting.
