Abstract  Abstract

According to one aspect a system and method of exchanging GRUUs (Globally Routed User Agent URI (Uniform Resource Identifier)) between a first telephony-enabled device and a second telephony enabled device using a circuit-switched message is provided. Once exchanged the telephony enabled devices can exchange SIP (session initiated protocol) communications routed by the GRUUs. Any one of the telephony-enabled devices can add a media component to the SIP communications. According to another aspect a system and method of generating GRUUs is provided. According to another aspect a system and method of handing off communications to a packet switched network from a circuit switched network is provided.
