Overview

Enea Netbricks MEGACO/H.248 protocol stack, MGC-BRICKS H.248, is a source code implementation of the MEGACO/H.248 Protocol. MEGACO is a protocol enabling a centralized softswitch (or Media Gateway Controller, MGC) to control media gateways between voice over packet (VOP) networks and traditional networks. MEGACO protocol is a joint work of IETF and ITU-T and named ‘MEGACO’ in IETF documents and H.248 in ITU-T documents, but the protocols are identical.

Enea’s H.248 stack is compliant with IETF RFC 3525 and ITU-T H.248.1 for version 2 and 3.
