Abstract
A communication system (10) includes a communication device (12) that supports communication using multiple number identification modules (70-74). Each NAM (70-74) supported by the communication device (12) is associated with a network (14,16) that provides a voice service or an enhanced service to the communication device (12). For outbound communication, the communication device (12) selects the appropriate NAM (70-74) in response to a request for a particular service. For inbound communication, the communication device (12) registers more than one NAM (70-74) to be able to respond to incoming pages from the networks (14, 16).
