Megaco
From Wikipedia, the free encyclopedia
The Gateway Control Protocol or Megaco/H.248 is a signalling protocol, used between a Media Gateway and a Media Gateway Controller in a VoIP network. It defines the necessary signalling mechanism to allow a Media Gateway Controller to control gateways in order to support voice/fax calls between PSTN-IP or IP-IP networks.
The protocol was the result of joint work of IETF and ITU. It is both defined by IETF's RFC 3525 (which obsoleted RFC 3015) and by ITU-T's H.248-1. It acts as the actual implementation of the Media Gateway Control Protocol.
