The Unable to show "metadata-from": No such page "_space_variables" supports H.323-H.323 calls with an audio and video stream. Unlike SIP video where all codecs are relayed through the Unable to show "metadata-from": No such page "_space_variables", H323 only supports a subset of the video codecs supported via SIP. The codecs are:
| Payload Type | Codec Variants |
|---|---|
| 31/Dynamic | H.261 |
| 34/Dynamic | H.263 |
| Dynamic | H.263-1998 |
| Dynamic | H.263-2000 |
| Dynamic | H.264 |
| Dynamic | H.264-RCDO |
| Dynamic | H.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.
Note
The SBC 52x0 and SBC 7000 systems support creating IP Interface Groups containing sets of IP interfaces that are not "processor friendly" (i.e. carried on physical Ethernet ports served by separate processors). However, restrictions exist regarding the usage of such Interface Groups.
(This ability does not apply to the SBC 51x0 and SBC 5400 systems which have only two physical media ports. IP interfaces from the two physical ports may be configured within the same IP Interface Groups without restriction.)
For complete details, refer to Configuring IP Interface Groups and Interfaces.
To View H323Trunk Group
On SBC main screen, go to Configuration > System Provisioning > Category: Trunk Provisioning > Trunk Group > H323Trunk Group. The H323Trunk Group window is displayed.
