Parameter Description
source port.
The valid range is 1 to 65,534. The default is 5080.
Web: SAS Default Gateway IP
EMS: Default Gateway IP
[SASDefaultGatewayIP]
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.
Web: SAS Registration Time
EMS: Registration Time
[SASRegistrationTime]
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 0 (Analog) to 2,000,000. The default is 20.
Web: SAS Local SIP TCP Port
EMS: Local SIP TCP Port
[SASLocalSIPTCPPort]
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 is 5080.
Web: SAS Local SIP TLS Port
EMS: Local SIP TLS Port
[SASLocalSIPTLSPort]
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 is 5081.
Web: SAS Connection Reuse
[SASConnectionReuse]
Enables the re-use of the same TCP connection for sessions
with the same user in the SAS application.

[0] Disable

[1] Enable (default)
The device can use the same TCP connection for multiple SIP
requests / responses for a specific SIP UA. The benefits of this
feature include less CPU and memory usage because fewer
TCP connections are open and reduced network congestion. 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.
Web/EMS: Enable Record-Route
[SASEnableRecordRoute]
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.

[0] Disable (default)

[1] Enable
The Record-Route header is inserted in a request by a SAS
