Parameter Description
Set).
Web/EMS: SAS Block
Unregistered Users
[SASBlockUnRegUsers]
Determines whether the device rejects SIP INVITE requests received
from unregistered SAS users. This applies to SAS Normal and
Emergency modes.

[0] Un-Block = (Default) Allow INVITE from unregistered SAS
users.

[1] Block = Reject dialog-establishment requests from un-registered
SAS users.
[SASEnableContactRepl
ace]
Enables the device to change the SIP Contact header so that it points
to the SAS host and therefore, the top-most SIP Via header and the
Contact header point to the same host.

[0] (default) = Disable - when relaying requests, the SAS agent
adds a new Via header (with the SAS IP address) as the top-most
Via header and retains the original Contact header. Thus, the top-
most Via header and the Contact header point to different hosts.

[1] = Enable - the device changes the Contact header so that it
points to the SAS host and therefore, the top-most Via header and
the Contact header point to the same host.
Note: Operating in this mode causes all incoming dialog requests to
traverse the SAS, which may cause load problems.
Web: SAS Survivability
Mode
EMS: Survivability Mode
[SASSurvivabilityMode]
Determines the Survivability mode used by the SAS application.

[0] Standard = (Default) Incoming INVITE and REGISTER requests
are forwarded to the defined Proxy list of SASProxySet in Normal
mode and handled by the SAS application in Emergency mode.

[1] Always Emergency = The SAS application does not use Keep-
Alive messages towards the SASProxySet, instead it always
operates in Emergency mode (as if no Proxy in the SASProxySet is
available).

[2] Ignore Register = Use regular SAS Normal/Emergency logic
(same as option [0]), but when in Normal mode incoming
REGISTER requests are ignored.

[3] Auto-answer REGISTER = When in Normal mode, the device
responds to received REGISTER requests by sending a SIP 200
OK (instead of relaying the registration requests to a Proxy), and
enters the registrations in its SAS database.

[4] Use Routing Table only in Normal mode = The device uses the
IP-to-IP Routing table to route IP-to-IP SAS calls only when in SAS
Normal mode (and is unavailable when SAS is in Emergency
mode). This allows routing of SAS IP-to-IP calls to different
destinations (and not only to the SAS Proxy Set).
Web: SAS Subscribe
Response
[SASSubscribeRespons
e]
Defines the SIP response upon receipt of a SUBSCRIBE message
when SAS is in Emergency mode. For example, if this parameter is set
to "200", then SAS sends a SIP 200 OK in response to a SUBSCRIBE
message, when in Emergency mode.
The valid value is 200 to 699. The default is 489.
Web: Enable ENUM
[SASEnableENUM]
Enables SAS to perform ENUM (E.164 number to URI mapping)
queries when receiving INVITE messages in SAS emergency mode.

[0] Disable (default)

[1] Enable
Web: SAS Binding Mode
EMS: Binding Mode Determines the SAS application database binding mode.

[0] URI = (Default) If the incoming AoR in the INVITE requests is
