we use CUCM 6.1.2 and we have the problem that a call terminate after 45minutes.
We updatet the Callmanager from 5.1.2 to 6.0.1 and from 6.0.1 to 6.1.2.
The failure occured also in Version 5.1.2 but not in 5.1.3 which is running in a testenvironment.
I called a 7961 oder 7970 from a extern Phone via PSTN. After ~ 45 minutes the established call was terminated automatically.
Have anybody the same Failure?
