Version 6.8 597 Mediant 2600 E-SBC
User's Manual 43. Configuration Parameters Reference
Parameter Description
CLI: user-agent-info
[UserAgentDisplayInfo]
User-Agent: myproduct/v.6.80.010.006
If not configured, the default string, <AudioCodes product-
name>/software version' is used, for example:
User-Agent: Audiocodes-Sip-Gateway-Mediant 2600 E-
SBC/v.6.80.010.006
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).
Web/EMS: SDP Session
Owner
CLI: 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
CLI: sdp-ver-nego
[EnableSDPVersionNeg
otiation]
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.
Web/EMS: Subject
CLI: usr-def-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.
Web: Multiple
Packetization Time
Format
EMS: Multi Ptime Format
CLI: mult-ptime-format
[MultiPtimeFormat]
Determines whether the 'mptime' attribute is included in the outgoing
SDP.
[0] None = (Default) Disabled.
[1] PacketCable = Includes the 'mptime' attribute in the outgoing SDP
- PacketCable-defined format.
The mptime' attribute enables the device to define a separate
packetization period for each negotiated coder in the SDP. The 'mptime'
attribute is only included if this parameter is enabled even if the remote
side includes it in the SDP offer. Upon receipt, each coder receives its
'ptime' value in the following precedence: from 'mptime' attribute, from
'ptime' attribute, and then from default value.
EMS: Enable P Time
[EnablePtime]
Determines whether the 'ptime' attribute is included in the SDP.
[0] = Remove the 'ptime' attribute from SDP.
[1] = (Default) Include the 'ptime' attribute in SDP.
Determines the device's behavior regarding call identifiers when a 3xx
