Hi,
I am stuck with the Cisco gateway (SIP-PSTN) disconnecting the call. The
scenario is that a SIP client makes a call which is forwarded to a Cisco
gateway, the call gets established but is disconnected after 20-30 seconds.
Bellow is the call trace from ethereal, the problem is that the Cisco
gateway (for some reason I don't know) sends a BYE. Does this have anything
to do with the ACKS?
I have tested the same scenario with the UA being Windows Messenger and the
Cisco Gateway, and there are no problems.
Any advice on troubleshooting this?
Thanks in advance,
Hamid
PS:
192.168.11.102 = UA
