Hi Mohamed,

Few more inputs required for further analysis.

Please share the topology and make one test call to get the debug ccsip all and share it.

Main thing to get to know is who is releasing the cal and what clear code (cause code) you are getting while call is being released?

Please share the calling number & called number too because this log contains lot of other number traces.

Also please share your topology i.e do you have sip trunk from CUCM to CME (gateway)?

IP address of CUCM?

Hello, It seems the CME is disconnecting the call after the default value of Min-SE timer (30 mins) expires.

So, you can try increasing the timer beyond 30 mins (1800 sec) under voice service voip.

Router(config)# voice service voip

Router(conf-voi-serv)# sip

Router(conf-serv-sip)# min-se  <90-86400>  Min value of Session Expires Header (in seconds)
