We have a company that bills different doctor's offices and hospitals. We need the capability to change the outbound caller ID name on the fly. We can have our carrier give us control of the name but I'm not sure what I need to do on the Call Manager or gateway side to get this accomplished. We are currently using CCM 4.1.3 and H323 gateways. What would be the best bay to go about making sure that a set phones have one caller ID name and another set of phones with a different caller ID name?
