Megaco (Media gateway control)

A joint standardization effort of the ITU-T (H.248) and the IETF

(RFC 3525) that defines the call control protocols employed in a physically decomposed gateway with subcomponents distributed across multiple devices that may be in multiple physically distinct locations.

Those subcomponents take the form of a Media Gateway (MG) and a Media Gateway Controller

(MGC), also known as a softswitch or a call agent. A single MGC can control a large number of MGs, each of which is optimized for a particular gateway application function to convert the media format between a packet network and another form of network, such as a public switched telephone network (PSTN) or
