Method and system for correlating telephone calls with information delivery

A method of coordinating the delivery of information through a data network with a call initiated using a call setup signaling message to a predetermined directory number (DN) through a switched telephone network (STN), comprising steps of:

• forwarding the call setup signaling message to a trunk in the STN controlled by a virtual switching point (VSP), so that the VSP lies in a signaling message path for the call;
• inserting an identifier string into the call setup signaling message, when the call setup signaling message is received at the VSP;
• inserting the identifier string and predetermined data from the call setup signaling message into a query message sent to a database in the data network to effect the retrieval of information associated with a calling party;
• forwarding the information and the identifier string to a data server associated with a facility that also terminates calls to the DN;
• and
• correlating the call setup signaling message with the information using respective identifier strings.

A system for correlating information received from a data network at a facility with a call made through a switched telephone network (STN) to the facility's telephony equipment, which is adapted to serve a plurality of calls simultaneously, the system comprising;

• a call control node interfacing a trunk in a telephone network adapted to perform call control messaging as commanded by a call control application, including the ability to insert an identifier string into a call setup signaling message;
• the call control application adapted to exchange messages with the call control node and to effect the delivery of the information with a copy of the identifier string, to a data server associated with the facility;
• and
• a data server of the facility that receives the information, and uses the accompanying identifier string to correlate the information with the call, wherein said information is used to perform an enhanced service feature.
