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

[Wes Sisk]

"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.

Regards,
Wes
