Claim:
1. A method of registering in an IP multimedia Subsystem (IMS)-enabled network, two or more user agents associated with a multi-contact user device, the method comprising the steps of: associating with each of the two or more user agents, a unique user device identification (ID) that is unique to the multi-contact user device, wherein the unique user device ID is derived from a global permanent identifier associated with the multi-contact user device; and providing, by each of the two or more user agents, the device ID to the IMS-enabled network; wherein when a communication request is directed towards the multi-contact user device, a serving node in the IMS enabled network manages the communication request according to a predetermined handling scheme that prevents redirection of the communication request from one registered user agent to another in response to the detection of identical user device IDs.
