Abstract
The present invention provides a novel method and apparatus for interconnecting a telephone call and voice processing system ("CVPS") with a telephone key system control unit ("KSU"). A plurality of digital feature telephone ports of the KSU are connected to the CVPS. These connections provide two-way digital feature telephone call information and telephone audio paths between the CVPS and the KSU. The CVPS emulates digital feature telephones on each of these ports permitting the CVPS to automatically perform all of the functions available to a human user of one of the digital feature telephones. Optionally, interposed lines connected to telephone central office telephone lines may be used to provide some of the connections between the KSU and the CVPS. Additionally the CVPS may, through the fully emulated digital feature telephone ports, query the KSU, telephone extensions and telephone lines in order to determine set up parameters and thereby self configure itself upon installation or modification of the installation.
