 supports H.323-H.323 calls with an audio and video stream. Unlike SIP video where all codecs are relayed through

the

the 

Spacevars
0product
, H323 only supports a subset of the video codecs supported via SIP. The codecs are:

Payload TypeCodec Variants
31/DynamicH.261
34/DynamicH.263
DynamicH.263-1998
DynamicH.263-2000
DynamicH.264
DynamicH.264-RCDO
DynamicH.264-SVC

The video stream is allowed to pass-thru if the Packet Service Profiles used for both legs of the call allows video; i.e have a non-zero value for video bandwidth.

This object is the H.323 Trunk Group for this zone.
