| H.248.1 packages for H.323 and H.324 interworking |
 |
This annex defines several H.248 packages that are intended for Media Gateways designed to support interworking between H.323 terminals and H.324 terminals. More specifically, this Annex 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. |
