[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.
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.
