AudioCodes Mediant 3000 User Manual

Version 7.0 905 Mediant 3000
User's Manual 58. Configuration Parameters Reference
Parameter Description
selected coder is G.729.
User-Agent Information
[UserAgentDisplayInfo]
Defines the string that is used in the SIP User-Agent and Server
response headers. When configured, the string <UserAgentDisplayInfo
value>/software version' is used, for example:
User-Agent: myproduct/v.6.80A.227.005
If not configured, the default string, <AudioCodes product-
name>/software version' is used, for example:
User-Agent: Audiocodes-Sip-Gateway-Mediant
3000/v.6.80A.227.005
The maximum string length is 50 characters.
Note: The software version number and preceding forward slash (/)
cannot be modified. Therefore, it is recommended not to include a
forward slash in the parameter's value (to avoid two forward slashes in
the SIP header, which may cause problems).
SDP Session Owner
[SIPSDPSessionOwner]
Defines the value of the Owner line ('o' field) in outgoing SDP messages.
The valid range is a string of up to 39 characters. The default is
"AudiocodesGW".
For example:
o=AudiocodesGW 1145023829 1145023705 IN IP4
10.33.4.126
[EnableSDPVersionNegoti
ation]
Enables the device to ignore new SDP re-offers (from the media
negotiation perspective) in certain scenarios (such as session expires).
According to RFC 3264, once an SDP session is established, a new
SDP offer is considered a new offer only when the SDP origin value is
incremented. In scenarios such as session expires, SDP negotiation is
irrelevant and thus, the origin field is not changed.
Even though some SIP devices don’t follow this behavior and don’t
increment the origin value even in scenarios where they want to re-
negotiate, the device can assume that the remote party operates
according to RFC 3264, and in cases where the origin field is not
incremented, the device does not re-negotiate SDP capabilities.
 [0] Disable = (Default) The device negotiates any new SDP re-offer,
regardless of the origin field.
 [1] Enable = The device negotiates only an SDP re-offer with an
incremented origin field.
Subject
[SIPSubject]
Defines the Subject header value in outgoing INVITE messages. If not
specified, the Subject header isn't included (default).
The maximum length is up to 50 characters.
[CoderPriorityNegotiation] Defines the priority for coder negotiation in the incoming SDP offer,
between the device's or remote UA's coder list.
 [0] = (Default) Coder negotiation is given higher priority to the remote
UA's list of supported coders.
 [1] = Coder negotiation is given higher priority to the device's (local)
supported coders list.
Note: The parameter is applicable only to the Gateway application.
Send All Coders on
Retrieve
Enables coder re-negotiation in the sent re-INVITE for retrieving an on-
hold call.
 [0] Disable = (Default) Sends only the initially chosen coder when the
