Description
■ [0] Restriction = In the incoming SDP offer, the device
uses only Allowed coders; the rest are removed from
the SDP offer (i.e., only coders common between those
in the received SDP offer and the Allowed coders are
used). If an Extension Coders Group is also assigned
(using the 'Extension Coders Group' parameter,
above), these coders are added to the SDP offer if they
also appear in Allowed coders.
■ [1] Preference = The device re-arranges the priority
(order) of the coders in the incoming SDP offer
according to their order of appearance in the Allowed
Audio Coders Group or Allowed Video Coders Group.
The coders in the original SDP offer are listed after the
Allowed coders.
■ [2] Restriction and Preference = Performs both
Restriction and Preference.
Note:
■ The parameter is applicable only if Allowed coders are
assigned to the IP Profile (see the 'Allowed Audio
Coders' or 'Allowed Video Coders' parameters).
■ For more information on the Allowed Coders feature,
see Restricting Coders.
Assigns an Allowed Video Coders Group. This defines
permitted video coders when forwarding video streams to
the SIP entity associated with the IP Profile. The video
coders are listed in the "video" media type in the SDP (i.e.,
'm=video' line). For this SIP entity, the device uses only
video coders that appear in both the SDP offer and the
Allowed Video Coders Group.
By default, no Allowed Video Coders Group is assigned
(i.e., all video coders are allowed).
To configure Allowed Video Coders Groups, see
Configuring Allowed Video Coder
Defines media types permitted for the SIP entity
associated with the IP Profile. The media type appears in
the SDP 'm=' line (e.g., 'm=audio'). The device permits
only media types that appear in both the SDP offer and this
configured list. If no common media types exist between
the SDP offer and this list, the device drops the call.
The valid value is a string of up to 64 characters. To
configure multiple media types, separate the strings with a
comma, e.g., " audio, text" (without quotes). By default, no
media types are configured (i.e., all media types are
permitted).
