SIP Call rings continues but destination phone is switched off

Dear All,

I have a problem with SIP trunk.

Problem Description >

I am dialing an external phone number (mobile number in this case) from my IP phone registered to CUCM 11.5 and I know the mobile is switched off, but I get ringing tone still.

Could someone give me a clue as to what is causing this behavior.

Send debug ccsip message please. The ringi g follows after the trying is received and the responder can actuall ring the destionation. Without debugs it is not possible to determine wherr the false positive ringing occurs. Or if this is expected behaviour
