Hello,
              My name is Abdul Rasheed, i am working on a voice recording solution using SIP trunk and BIB.  It was noticed that while running the solution for 1 or 1.5 months in one site,  the recording will suddenly stop  and when i checked it was found that after the ACK is recieved from CUCM , it will immedietly send a BYE closing the session and the reason for the BYE is  Q.850 Cause =65  when i checked i found that the cause=65 means "bearer capability not implemented"  i am not sure why this error coming up immedietly on a working system after running for 1.5 months.  Is there any thing in CUCM configuration should i verify ?
 
Thanks and Regards
Abdul Rasheed
