We are running ccm 5.1.3 and have an MGCP CAS T1 connected to another phone system. I would like to know if there is a way to present a predefined name on inbound calls from that T1 tie trunk. Currently we get unknown name when receiving a call. I know caller ID doesn't work but can I define a trunk group name to display so at least our users know what location is calling. We don't need the number at this point.
