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:

[SER] MY.SER.IP.ADDRESS
[CISCO AS5300] MY.AS5300.IP.ADDRESS

And maybe I found little bad Via header in
ACK message from Asterisk (via SER) to AS5300.

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?
