Abstract
Transaction Capabilities Application Part (TCAP) information from an Signaling System 7 (SS7) network (11) is provided, in response to an original SIP-compatible request by an SIP entity (17) in an SIP network (10), to the SIP network where the TCAP information is then used to facilitate call setup and routing of the call. In one embodiment, the SIP network locally stores the TCAP information upon receipt (at least temporarily) such that the TCAP information is available for subsequent local use without requiring a correspond inquiry to the SS7 network.
