Also known as Megaco, H.248 is a protocol for controlling media gateways via a softswitch/Media Gateway Controller (MGC).

TelcoBridges and H.248
Toolpack now supports the H.248 protocol.
As indicated in the diagram below, the H.248 stack is a module in the media gateway application residing on the application server. It communicates with the various Toolpack classes (CAFClass, CMC Library, CMC Class) as required via a new Media Leg API. In turn, the media gateway application communicates with the softswitch / media gateway controller via the H.248 protocol.
