METHODS, SYSTEMS, AND COMPUTER PROGRAM PRODUCTS FOR PROVIDING TELECOMMUNICATIONS SERVICES BETWEEN A SESSION INITIATION PROTOCOL (SIP) NETWORK AND A SIGNALING SYSTEM 7 (SS7) NETWORK

摘要

Methods, systems, and computer program products for providing telecommunication services between a SIP network and an SS7 network are disclosed In one method, SIPISS7 gateway receives an INVITE message from a SIP proxy server The SIPISS7 gateway extracts a called party number from the INVITE message and determines whether a telecommunications service is required and a type of service required for the INVITE message based on the called party number The SIPISS7 gateway then formulates an SS7 query to a database corresponding to the identified service type The SIPISS7 gateway receives a response from the database and uses data from the response to facilitate completion of the call In one example, the SIPISS7 gateway may forward a routing number extracted from the response back to the originating SIP proxy server.
