Configuring Allowed Video Coder Groups

The Allowed Video Coders Groups table lets you configure up to four Allowed Video
Coders Groups for SBC calls. Each Allowed Video Coders Group can be configured with
up to 10 coders. An Allowed Video Coders Group defines a list of video coders that can be
used when forwarding video streams to a specific SIP entity. The coders can include pre-
defined video coders and user-defined (string) video coders for non-standard or unknown
coders.
Allowed Video Coders Groups are assigned to SIP entities, using IP Profiles (see
'Configuring IP Profiles' on page 405). The video coders appear in the SDP media type
"video" ('m=video' line). Coders that are not listed in the Allowed Video Coders Group are
removed from the SDP offer that is sent to the SIP entity. Only coders that are common
between the coders in the SDP offer and the coders listed in the Allowed Video Coders
Group are used. Thus, Allowed Video Coders Groups enable you to enforce the use of only
specified coders. For more information, see 'Restricting Audio Coders' on page 628.
The order of appearance of the coders listed in the Allowed Video Coders Group
determines the priority (preference) of the coders in the SDP offer. The device arranges the
SDP offer's coder list according to their order in the Allowed Video Coders Group. The
priority is in descending order, whereby the first coder in the list is given the highest priority
and the last coder, the lowest priority. For more information, see 'Prioritizing Coder List in
SDP Offer' on page 632.

The following procedure describes how to configure Allowed Video Coders Groups through
the Web interface. You can also configure it through ini file (AllowedVideoCodersGroups
and AllowedVideoCoders) or CLI (configure voip > coders-and-profiles allowed-video-
coders-groups; configure voip > coders-and-profiles allowed-video-coders <group
index/coder index>).
