H.245 and G.726 Configuration
To enable this feature, you do need to set up media profile configurations appropriately. Media profiles now allow you to set the configuration to any of the four G.726 encodings (as defined by ITU G726 Annex B and RFC 3551). You must create one media profile for each of the four different supported data rates. In addition, you are also required to set a genericAudioCapability media profile.
