User's Manual 43. Configuration Parameters Reference
Parameter Description

[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
[SASSubscribeResponse]
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
[SASBindingMode]
Determines the SAS application database binding mode.

[0] URI = (Default) If the incoming AoR in the INVITE
requests is using a ‘tel:’ URI or ‘user=phone’ is defined, the
binding is performed according to the user part of the URI
only. Otherwise, the binding is according to the entire URI,
i.e., User@Host.

[1] User Part only = The binding is always performed
according to the User Part only.
Web: SAS Emergency Numbers
[SASEmergencyNumbers]
Defines emergency numbers for the device's SAS application.
When the device's SAS agent receives a SIP INVITE (from an IP
phone) that includes one of the emergency numbers (in the SIP
user part), it forwards the INVITE to the default gateway
(configured by the parameter SASDefaultGatewayIP), i.e., the
device itself, which sends the call directly to the PSTN. This is
important for routing emergency numbers such as 911 (in North
America) directly to the PSTN. This is applicable to SAS
operating in Normal and Emergency modes.
Up to four emergency numbers can be defined, where each
number can be up to four digits.
[SASEmergencyPrefix]
Defines a prefix that is added to the Request-URI user part of
the INVITE message that is sent by the device's SAS agent
when in Emergency mode to the default gateway or to any other
destination (using the IP-to-IP Routing table). This parameter is
required to differentiate between normal SAS calls routed to the
