Abstract
A system, apparatus and method for identifying particular applications in a multi-application terminal environment to which incoming network messages should be directed. A registration message is generated at a terminal having multiple applications, and is transmitted to a registrar to be registered. The registration message includes a user address of record, and at least one contact header including at least a contact Uniform Resource Identifier (URI) of the terminal and an application identifier of one of the applications. Incoming messages subsequently received at the terminal include the registered application identifier of one of the SIP-related applications operating at the terminal, such as included with an optional field of the terminal URI. Upon receipt of the incoming message, the terminal forwards it to the application identified by the application identifier.
