Abstract
A method for providing combined local, toll, toll free services, and number portability, to a calling party originating calls from an IP-based communication devices which are coupled to an IP-based multi-media service provider. The method includes receiving a SIP INVITE message, which includes a multi-media service identifier, at the multi-media provider. The SIP INVITE message represents a call request for a multi-media service. The SIP INVITE message is processed at the multi-media provider for determining if the call request can be satisfied. If the multi-media service provider includes resources for satisfying the call, the multi-media service identifier of the SIP INVITE message is set to a first predetermined state and the call is processed. If the multi-media service provider does not include resources for satisfying the call, the multi-media service identifier of the SIP INVITE message is set to a second predetermined state and the call is processed elsewhere.
