We have recently rolled out the ability for our employees to dial external phone numbers via SIP through our carrier. The problem we are experiencing is that the CPND of the phone set that is making the call to an external phone number via SIP is passing with their calling phone number. We also have office-to-office calling going over the same SIP trunk group within our PBX that we still want the CPND to pass. Is there a way to stop the CPND from passing on calls to external phone numbers and still allow the CPND to pass for office-to-office calls?
