[cisco-voip] Calls over trunk drop after 5:18 min

[Dennis Heim]

And if you are SIP, then you can have reinvite timing issues too. Seen that before.

What protocol are you using on the trunks? If they are SIP trunks then H.323 timers should not have an affect. This goes back to my question about topology.

Yes Wes, I have Cisco ASA between sites but I've already set the H323 timer on the ASA to 3:00:00. And yes this is case only for calls that traverse over trunks aka via the ASA firewall which was recently upgraded with new IOS and installed an IPS module. Any suggestions, please...

"temp fail" on your CIPC means CM has lost call signaling communication with the remote device. This coincides with the concerns about a firewall or other device aborting the control session.

What is the topology between CM, firewall, and remote device?

Keepalives for H323 should, generally, be set to true.  That sends keepalives on the socket to keep firewall from timing out the session.

Wes

I've tried setting the h323 timer to 3:00:00 and setting the "Allow Peer to Preserve H.323 Calls"  parameter to true and setting "Allow TCP KeepAlives For H323" to false but it's almost the same. At almost the same time I loose audio (call is still connected) and get "Temp Fail" message on the screen on my IP Comunnicator.
