this default gateway.
The address can be configured as an IP address (dotted-decimal
notation) or as a domain name (up to 49 characters). You can also
configure the IP address with a destination port, e.g., "10.1.2.3:5060".
The default is a null string, i.e., the local IP address of the gateway.
Defines the value of the SIP Expires header that is sent in a 200 OK
response to an incoming REGISTER message when in SAS 'Emergency
Mode'.
The valid range is 10 to 2,000,000. The default is 20.
Enables the re-use of the same TCP connection for sessions with the
same user in the SAS application.

The device can use the same TCP connection for multiple SIP requests /
responses for a specific SIP UA. For example, assume the following:

User A sends a REGISTER message to SAS with transport=TCP.

User B sends an INVITE message to A using SAS.
In this scenario, the SAS application forwards the INVITE request using
the TCP connection that User A initially opened with the REGISTER
message.
Determines whether the device's SAS application adds the SIP Record-
Route header to SIP requests. This ensures that SIP messages traverse
the device's SAS agent by including the SAS IP address in the Record-
Route header.

The Record-Route header is inserted in a request by a SAS proxy to
force future requests in the dialog session to be routed through the SAS
agent. Each traversed proxy in the path can insert this header, causing
all future dialogs in the session to pass through it as well.
When this feature is enabled, the SIP Record-Route header includes the
URI "lr" parameter, indicating loose routing, for example:
Record-Route: <sip:server10.biloxi.com;lr>
Defines the Proxy Set (index number) used in SAS Normal mode to
forward REGISTER and INVITE requests from users that are served by
the SAS application.
The valid range is 0 to 5. The default is 0 (i.e., default Proxy Set).
Defines the Proxy Set (index number) used in SAS Emergency mode for
fallback when the user is not found in the Registered Users database.
Each time a new SIP request arrives, the SAS application checks
whether the user is listed in the registration database. If the user is
located in the database, the request is sent to the user. If the user is not
found, the request is forwarded to the next redundant SAS defined in the
Redundant SAS Proxy Set. If that SAS Proxy IP appears in the Via
header of the request, it is not forwarded (thereby, preventing loops in
the request's course). If no such redundant SAS exists, the SAS sends
the request to its default gateway (configured by the parameter
SASDefaultGatewayIP).
The valid range is -1 to 5. The default is -1 (i.e., no redundant Proxy
