its 2xx response.
Determines whether a Cisco gateway exists at the remote side.

[0] = (Default) No Cisco gateway exists at the remote side.

[1] = A Cisco gateway exists at the remote side.
When a Cisco gateway exists at the remote side, the device must
set the value of the 'annexb' parameter of the fmtp attribute in the
SDP to 'no'. This logic is used if the parameter
EnableSilenceCompression is set to 2 (enable without adaptation).
In this case, Silence Suppression is used on the channel but not
declared in the SDP.
Note: The IsCiscoSCEMode parameter is applicable only when the
selected coder is G.729.
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.6.40.010.006
If not configured, the default string, <AudioCodes product-
name>/software version' is used, for example:
User-Agent: Audiocodes-Sip-Gateway-Mediant 800B
Gateway and SBC/v.6.40.010.006
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).
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
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.
Defines the Subject header value in outgoing INVITE messages. If
