However, the Softswitch Consortium also promotes interoperability based on the Session Initiation Protocol (SIP), the
Media Gateway Control Protocol (MGCP), and Real-time Transport Protocol (RTP).
TransMedia and DGM&S Telecom will take advantage of the emerging Internet Protocol Device Control (IPDC) and
Media Gateway Control Protocol (MGCP) standards, and Parlay API industry consortium work by DGM&S Telecom, Microsoft (Nasdaq:MSFT), British Telecom (NYSE:BTY), Nortel Networks (NYSE:NT) and Siemens (OTC BB foreign:SMAWY), in developing the new capabilities.
With
media gateway control protocol (MGCP) and its business phone extensions, however, a standard for stimulus protocols exists, providing the necessary low-level control required for even the most complex business telephony system features.
Version 7.0 was designed to reduce the cost of providing telephony functions to distributed systems or small satellite offices over Internet Protocol (IP), support industry-standard
Media Gateway Control Protocol (MGCP) trunks and offer other various feature enhancements.
The reference design supports G.711, G.722, G.723, and G.728 asymmetrical voice encoding and decoding as well as the Simple Gateway Control Protocol (SGCP) which is the core of the newly announced
Media Gateway Control Protocol and the H.323 Internet telephony standard.
The
Media Gateway Control Protocol (MGCP) Functional and Performance test suite provides rigorous media gateway controller performance testing to RFC 2705 and allows stress testing two million busy-hour call attempts per port for any softswitch.
