User's Manual
id when sending REGISTER again after registration expiration. RFC
5627 specifies that the remote target is a GRUU target if its' Contact
URL has the "gr" parameter with or without a value.

Using GRUU: The UA can place the GRUU in any header field that
can contain a URI. It must use the GRUU in the following
messages: INVITE request, its 2xx response, SUBSCRIBE request,
its 2xx response, NOTIFY request, REFER request and 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 Silence Suppression is configured 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.7.20A.000.038
If not configured, the default string, <AudioCodes product-
name>/software version' is used, for example:
User-Agent: Audiocodes-Sip-Gateway-Mediant 500 E-
SBC/v.7.20A.000.038
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
Note: For the SBC application, the parameter is applicable only when
the device creates a new SIP message (and SDP) such as when the
device plays a ringback tone. The parameter is not applicable to SIP
messages that the device receives from one end and sends to another
(i.e., does not modify the SDP's 'o' field).
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
