Abstract
A system and method for integrating conventional enterprise communication systems into an IMS-based services environment are disclosed. In one embodiment, when a call request is received for a call between first and second local users of a PBX, the PBX determines whether a class of service for either the first or second local user is for Exposed Local Call (ELC) processing. If so, then call information is routed through a Session Initiation Protocol (SIP) core network that is coupled to an Internet Protocol Multimedia Subsystem (IMS) server to provide IMS services to the call.
