ITU-T Recommendations

This Recommendation defines several H.248.1 packages that are intended for Media Gateways designed to support interworking between H.323 terminals and H.324 terminals. More specifically, this Recommendation contains: package "h324" for creating terminations supporting H.324, package "h245" for creating terminations supporting H.245 channels for H.324 calls, package "h323bc" for creating terminations supporting H.245 channels for H.323 calls, package "h245com" for the communication of H.245 commands between a MGC and MG, and package "h245ind" for the communication of H.245 indications. NOTE ? This Recommendation has been renumbered. It was formerly known as ITU-T Rec. H.248, Annex M4.Amendment 1 defined packages, which extend the existing H.324, H.245 command and H.245 indication packages by adding properties.Amendment 2 defines a package which enables sending H.245 messages between a Media Gateway Controller (MGC) and a Media Gateway (MG) when the interworking function is handled by the MGC.
