precedence call level.

Table 6-39: 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.
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.
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). The default
is a null string, which is interpreted as the local IP address of the
gateway.
Determines 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
This parameter is obsolete; instead, use the parameter
SASRegistrationManipulation.
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.
