Description
Defines media types permitted for this SIP entity. 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., "media, audio" (without quotes). By default,
no media types are configured (i.e., all media types are
permitted).
Assigns an Allowed Coders Group to this SIP entity. This
defines audio (voice) coders that can be used for this SIP
entity.
To configure Allowed Coders Groups, see Configuring
Allowed Audio Coder Groups on page 543.
For a description of the Allowed Coders feature, see
''Restricting Coders'' on page 513.
Assigns an Allowed Video Coders Group to this SIP entity.
This defines permitted video coders when forwarding
video streams to the SIP entity. 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 ID.
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 Groups on page 544.
Defines the mode of the Allowed Coders feature for this
SIP entity.

[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 ID' parameter,
above), these coders are added to the SDP offer.

[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
Coders Group or Allowed Video Coders tables. The
coders received in the SDP offer are listed after the
Allowed coders.

[2] Restriction and Preference = Performs both
Restriction and Preference.
Notes:

This parameter is applicable only if Allowed coders are
assigned to the IP Profile (using the 'Allowed Coders
Group ID' or 'Allowed Video Coders Group ID'
parameters).
