We are using CUCM 8.5 BE. Sometimes it is reported that the call automatically disconnects after random period of time. Before the call disconnects, an announcement is played "Your call your call will be disconnected after 60 sec". This announcement is repeated after every 15 seconds and the call finally disconnects after 60 sec. The problem mainly occurs on calls made to UAE.
For one call, CDR CMR dump shows origCause_value = 16, destCause_value = 0 while for other origCause_value = 0, destCause_value = 16
