[Skunkworks] Caller ID in Call-Centre Environment

Hi guys, Quick one : How feasible is it to implement a centrally managed caller-ID feature in an environment where incoming calls in a '*call-centre-like*' environment can be attended to by any of the members in a team. The outfit has one single contact number and each operative has their own desktop phone to attend to incoming calls. Can the list of regular callers be centrally managed, to eliminate the need to load the same in each and every operative's desk-phone? Sounds like something that should already exist to me. Any pointers? Tony.
