I am attempting to send calls from various Ip phones (Snom 105,200 and SIP
Express ATA) to a default SIP gateway (Cisco AS5300) and for some reason my
calls are failing 2 seconds after the called party picks up. This is what
the Asterisk console is displaying during the call attempt:
-- Executing Dial("SIP/7708183797-28a7",
"SIP/16783528833@66.102.15.212|30") in new stack
-- Called 16783528833@66.102.15.212
-- SIP/66.102.15.212-bfdc is making progress passing it to
SIP/7708183797-28a7
-- SIP/66.102.15.212-bfdc answered SIP/7708183797-28a7
-- Attempting native bridge of SIP/7708183797-28a7 and
SIP/66.102.15.212-bfdc
-- Got SIP response 481 "Invalid CSeq Number" back from
66.102.15.212
== Spawn extension (default, 6783528833, 1) exited non-zero on
'SIP/7708183797-28a7'
At this point I am not sure if it is a problem with the config on my cisco
box, or with the setup in my extension or sip.conf files. The cisco box is
handling SIP calls from another registrar now, so I doubt that it is the
problem.
Has anyone been able to get this setup working?
Thanks,
Brian
