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
Profiles). 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
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
The Allowed Audio Coders Groups table is applicable only to the SBC application.
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
video-coders < group index/coder index>).
➢
To configure an Allowed Video Coders Group:
