AudioCodes Mediant 1000

User's Manual 402 Document #: LTRT-27045
Mediant 1000B Gateway & E-SBC
Parameter Description
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 on page 618.
Allowed Video Coders
allowed-video-coders-group-
name
[IpProfile_SBCAllowedVideoC
odersGroupName]
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 Groups on page 392.
Allowed Media Types
sbc-allowed-media-types
[IpProfile_SBCAllowedMediaT
ypes]
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).
Direct Media Tag
sbc-dm-tag
[IPProfile_SBCDirectMediaTa
g]
Defines an identification tag for enabling direct media (no Media
Anchoring) for the SIP entity associated with the IP Profile. Direct
media occurs between all endpoints whose IP Profiles have the
same tag value (non-empty value). For example, if you set the
parameter to "direct-rtp" for two IP Profiles "IP-PBX-1" and "IP-PBX-
2", the device employs direct media for calls amongst endpoints
associated with IP Profile "IP-PBX-1", for calls amongst endpoints
associated with IP Profile "IP-PBX-2", and for calls between
endpoints associated with IP Profile "IP-PBX-1" and IP Profile "IP-
PBX-2".
The valid value is a string of up to 16 characters. By default, no value
is defined.
For more information on direct media, see Direct Media on page 616.
Note: If you enable direct media for the IP Profile, make sure that
your Media Realm provides sufficient ports, as media may traverse
the device for mid-call services (e.g., call transfer).
RFC 2833 Mode
sbc-rfc2833-behavior
[IpProfile_SBCRFC2833Beha
vior]
Defines the handling of RFC 2833 SDP offer-answer negotiation for
the SIP entity associated with the IP Profile.
 [0] As is = (Default) The device does not intervene in the RFC
2833 negotiation.
 [1] Extend = Each outgoing offer-answer includes RFC 2833 in
the offered SDP. The device adds RFC 2833 only if the incoming
offer does not include RFC 2833.
 [2] Disallow = The device removes RFC 2833 from the incoming
offer.
