Media Gateway Control. Also know as H.248. A joint IETF/ITU standard to replace MGCP as the communications protocol between Media Gateway Controllers and Media Gateways.
MEGACO was developed by the ITU-T SG16 and IETF WG MEGACO and defines the control protocol between the media gateway controller (call agent) and the media gateway. The protocol provides - Control for various types of terminations, Support for negotiation of call capabilities, Multi user call scenarios, Rich termination dynamics, Quality of Service (QoS)and traffic measurement support, error reporting on protocol, call and capability and network failures.
Megaco is a call control protocol that addresses the relationship between the Media Gateway (MG), which converts circuit-switched voice to packet-based traffic, and the Media Gateway Controller (MGC), sometimes called a call agent or softswitch, which dictates the service logic of that traffic. Megaco is designed for intradomain remote control of devices such as VoIP gateways, remote access servers, Digital Subscriber Line Access Multiplexers (DSLAMs), Multiprotocol Label Switching (MPLS) routers, optical cross-connects and PPP session aggregation boxes.
