Multi-Vendor Integration Protocol
Encyclopedia
The Multi-Vendor Integration Protocol (MVIP) is a hardware bus for computer telephony integration
(Audiotex) equipment, a PCM data highway for interconnecting expansion boards inside a PC
. It was invented and brought to market by Natural Microsystems Inc (now NMS Communications).
Used to build call center equipment using regular PCs, MVIP provides a second communications bus within the computer that can multiplex up to 256 full-duplex voice channels from one voice card to another. Digital voice, fax and video is bussed over a ribbon cable connected at the top of each ISA or PCI card. MVIP products make a PC perform like a small-scale PBX. The protocol accommodated for a variety of expansion boards, including trunk interfaces (usually T1
or ISDN), voice processing boards equipment speech recognition
or fax processing. Each board could optionally provide a switch that could interconnect voice channels on the bus, allowing for a flexible routing of calls within the MVIP bus.
The MVIP bus was promoted as an alternative to the then-dominant PEP
bus by Dialogic Corporation
which had much less capacity and was not an open standard.

Speech recognition converts spoken words to text. The term "voice recognition" is sometimes used to refer to recognition systems that must be trained to a particular speaker—as is the case for most desktop recognition software...
