Hi I have an issue with Cisco ASA 5520, The summary is below!
Packet # 1 on inside capture the Call-ID was: Call-ID: 2a54f680-
Packet # 1 on outside interface the Call-ID was: Call-ID: 2a54f680-
[email protected] --- this bcz of the inspection.
Packet # 2 on outside capture the Call-ID was: Call-ID: 2a54f680-
Packet # 2 on inside capture the Call-ID stay: Call-ID: 2a54f680-
[email protected] --- this is the problem.
(This suppose to be Call-ID: [email protected])
The inspection should change the Call-ID for the incoming packet as it
did with the outgoing packet. Whenever, the CM receive the trying
message with different Call-ID it considered as new session and it keep
sending invitation messages for the SIP provider.
NAT is enabled.
How to fix the above problem ?
Any help will be appreciated.
Verify any Xlate entries on SIP server. You might also want to include inspect SIP in your global policy. There are also lots of bugs in 8.0(3) regarding SIP handling
