You may see some hint in the log of Cisco AS if you
enable more detailed
debug, for example:
debug sip all
debug voip ccapi inout
Just be prepared for the huge about of log and system slowdown!

Hi,
rport missing is no problem at all, default 5060 is then used.
The branch=0 in the ACK might be the problem (if Cisco does not match it
with the INVITE (but then it should retransmit the 200 OK reply)).
You can try add syn_branch=0 to the ser.cfg to have the branch id
calculated for ACKs too.

I got an additional SIP message log from my
5300.
Scenario:
[UA] => [Asterisk] => [SER] => [CISCO AS5300] => [PSTN]
[UA] "12"
[Asterisk] 0355558888(a)MY.ASTERISK.IP.ADDRESS
[SER] MY.SER.IP.ADDRESS
[CISCO AS5300] MY.AS5300.IP.ADDRESS
[PSTN] T1 Line
And maybe I found little bad Via header in
ACK message from Asterisk (via SER) to AS5300.
Feb 7 03:22:34.401: Received:

Record-Route: <sip:MY.SER.IP.ADDRESS;ftag=as2ad98fe4;lr>
Via: SIP/2.0/UDP MY.SER.IP.ADDRESS;branch=0
Via: SIP/2.0/UDP
MY.ASTERISK.IP.ADDRESS:5060;branch=z9hG4bK0a0daaf9;rport=5060
...
Why Via header looks like no branch value and port value...?
And all SIP messages have no Route header.
I attached AS5300 SIP message log (see below).
Any ideas?
