Table A-63: SAS Parameters
Enables the Stand-Alone Survivability (SAS) feature.

[0] Disable Disabled (default)

[1] Enable = SAS is enabled
When enabled, the device receives the registration requests
from different SIP entities in the local network and then forwards
them to the defined proxy. If the connection to the proxy fails
('Emergency Mode'), the device serves as a proxy by allowing
calls internal to the local network or outgoing to PSTN.
Note: For this parameter to take effect, a device reset is
required.
Defines the local UDP port for sending and receiving SIP
messages for SAS. The SIP entities in the local network need to
send the registration requests to this port. When forwarding the
requests to the proxy ('Normal Mode'), this port serves as the
source port.
The valid range is 1 to 65,534. The default value is 5080.
Defines the Default Gateway used in SAS 'Emergency Mode'.
When an incoming SIP INVITE is received and the destination
Address-Of-Record is not included in the SAS database, the
request is immediately sent to 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 10to 2,000,000. The default value is 20.
Defines the local TCP port used to send/receive SIP messages
for the SAS application. The SIP entities in the local network
need to send the registration requests to this port. When
forwarding the requests to the proxy ('Normal Mode'), this port
serves as the source port.
The valid range is 1 to 65,534. The default value is 5080.
Defines the local TLS port used to send/receive SIP messages
for the SAS application. The SIP entities in the local network
need to send the registration requests to this port. When
forwarding the requests to the proxy ('Normal Mode'), this port
serves as the source port.
The valid range is 1 to 65,534. The default value is 5081.
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
