Media Gateway Control Protocol (Megaco)
Megaco (a contraction of "Media Gateway Controller") is a signalling protocol, used between a Media Gateway and a Media Gateway Controller (also known as a Call Agent or a Soft Switch) in a VoIP network. It defines the necessary signalling mechanism to allow a Media Gateway Controller (Call agent) to control gateways in order to support voice/fax calls between PSTN-IP or IP-IP networks.
This protocol is defined by IETF RFC 3525 and was the result of joint work of IETF and ITU. It is also known as H.248. H.248 is the name given to it by the ITU, Megaco is the IETF name.
