Abstract

An call distribution system is provided for distributing calls and information relating to the calls to different stations serviced by telephones and computers. The call distribution system comprises one or more telephone lines (52, 300), with or without a PBX (50) or an ACD, a first telephony interface device (62, 308) connected to a computer and to the telephone lines (52, 300), a second telephony interface device (76, 306) connected to the telephone lines (52, 300), a call control process (116, 350) that controls the telephony functions on the first telephony interface device (62, 308), a telephony interface process (254, 354) that controls the telephony functions on the second telephony interface device (76, 306), and an interprocess message dispatch system (112, 352) that is used to send messages between the call control process (116, 350) and the telephony interface process (254, 354).
