Call and data correspondence in a call-in center employing virtual restructuring for computer telephony integrated functionality

A telephone call-routing system, comprising:

• a call-in center comprising a plurality of agent stations, individual ones of the agent stations having a telephone and a computer platform including a video display unit (VDU), the telephone and the computer platform connected by a Telephone Application Programming Interface (TAPI)-compliant bridge, with a plurality of the computer workstations connected to one another, to a first processor, and to a database on a local area network (LAN);
• and
• a call-routing center comprising a telephony switch adapted to switch telephone calls to the telephones at the call-in center and a first processor adapted to route computer-simulated telephone calls to the computer platforms at the agent stations;
• wherein the computer workstation is adapted to retrieve origination data for incoming calls, both conventional telephony and computer-simulated, and to report the origination data to the first processor, and wherein the first processor is adapted to use the origination data to correlate the caller with further data retrieved from the database for display on the VDU, to service calls from specific Service Control Points (SCPs) and to block display of data at agent station VDUs for any call not identified as originating at one of the specific SCPs.
