Abstract: A telephony call center has agent workstations having telephones connected to station-side ports of a telephone switching apparatus adapted to receive and switch conventional telephone calls to the telephones, and also computer platforms connected on a local area network (LAN). A processor also connected on the LAN has a wide area network (WAN) port and is adapted to receive and distribute computer-simulated telephone calls from the WAN to computer platforms at the agent stations. At individual agent stations the telephone and computer platform is connected by a Telephone Application Programming Interface (TAPI)-compliant bridge. Status of calls of both types at agent workstations is communicated to a network-level router by the processor having a WAN connection, which may also receive computer-simulated calls. The router may then make routing decisions based on agent status relative to both kinds of calls.
