Abstract
A system and method of using multiple service providers to provide subscriber services on a per call basis achieved by using H.323 capability in a gatekeeper to identify call signaling transfer addresses used for each call. Service subscription data is based on the address or alias being used to place or receive a call. Since telephones can have the ability to register multiple addresses simultaneously, the same phone can receive service from multiple providers simultaneously. In addition, it is possible that some of the addresses or aliases used may be part of a private address space such as, for instance, a private branch exchange (PBX) system. This would enable service from a provider that is not a registered public telephone service provider.
