I have a situation that when a call is placed from an offnet phone to our phones then forwarded to a offnet phone number that is in the same area code as my CUCM the phone will ring once and go busy, if the destination number is in a differnt area code everything works. To make this more interesting this happens when the call comes into a phone that is on our Nortel PBX that is trunked to our CUCM. All of our calls come in and out of our SIP trunk.
Any help resolving this is greatly appreciated.
