Abstract
Methods, systems, and computer program products for providing telecommunication services between a SIP network and an SS7 network are disclosed. In one method, SIP/SS7 gateway receives an INVITE message from a SIP proxy server. The SIP/SS7 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 SIP/SS7 gateway then formulates an SS7 query to a database corresponding to the identified service type. The SIP/SS7 gateway receives a response from the database and uses data from the response to facilitate completion of the call. In one example, the SIP/SS7 gateway may forward a routing number extracted from the response back to the originating SIP proxy server. In another example, the SIP/SS7 gateway may generate a new INVITE message and forward the new INVITE message to a terminating SIP proxy server. In yet another example, the SIP/SS7 gateway may formulate a second query to the same database or to a different database to obtain further information for facilitate completion of the call.
