Abstract

A method and apparatus for enabling registration of an Aggregate End Point (AEP) device that is incapable of supporting a Session Initiation Protocol (SIP) based Internet Protocol Multimedia Subsystem (IMS) registration are disclosed. The method performs a static registration of the AEP device in a plurality of network elements associated with an Internet Protocol Multimedia Subsystem (IMS) network by provisioning. The method then processes an originating call request or a terminating call request associated with the AEP device using the static registration.
