Hi,
Try changing the CUCM Service Parameter "SIP Session Expires Timer" from the default (1800 secconds =30 mininutes) to a higher value; for example 14400 seconds (4 hours).
Pls give feedback afterwards (Let us konw If it helped).
Cheers

Hi Emmanuel,
I'd be curious to know if this is truly the resolution or a workaround. It would seem that modifying the Session Expires timer in CUCM would only increase the time to 4 hours before the call dropped potentially?

The SIP session timer was the correct solution for that particular issue.
