Marconi announced Session Initiation Protocol (SIP) capabilities for its enhanced SoftSwitch, opening the door to a host of new services that will harness the full potential of a converged voice and data network. Marconi said its SoftSwitch now provides interoperability between SIP, PSTN and MGCP/H248/H323 environments. Trials of the SIP-enabled SoftSwitch are already underway with selected customers. Marconi is also working with third-party customer premises equipment (CPE) and application server manufacturers to deliver a range of applications based on its SoftSwitch. http://ww.marconica.com

From the Technology Graveyard
You just read about SIP. Here is what it replaced:
MGCP / Megaco (H.248) served from 1999. What ultimately replaced it?
MGCP / Megaco (H.248) a master/slave model where a central call agent (softswitch) controlled dumb media gateways, instructing them how to set up and tear down media streams. Its job passed to SIP — but the problem it solved, and the ideas it proved, live on in what replaced it. The standard rests here in the archive. One of 198 technologies here that opened a door and then held it for the next.
