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.
CLI: sas-emerg-prefix
[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 default gateway
and emergency SAS calls. Therefore, this allows you to define different
manipulation rules for normal and emergency calls.
This valid value is a character string. The default is an empty "" string.
Web: SAS Entering
Emergency Mode
CLI: sas-enter-emg-mode
[SASEnteringEmergenc
yMode]
Determines for which sent SIP message types the device enters SAS
Emergency mode if no response is received for them from the proxy
server.
[0] = (Default) SAS enters Emergency mode only if no response is
received from sent SIP OPTIONS messages.
[1] = SAS enters Emergency mode if no response is received from
sent SIP OPTIONS, INVITE, or REGISTER messages.
Note: If the keep-alive mechanism is disabled for the Proxy Set (in the
Proxy Set table) and this parameter is set to [1], SAS enters
Emergency mode only if no response is received from sent INVITE or
REGISTER messages.
Web: SAS Inbound
Manipulation Mode
CLI: sas-inb-manipul-md
[SASInboundManipulati
onMode]
Enables destination number manipulation of incoming INVITE
messages when SAS is in Emergency mode. The manipulation rule is
done in the IP to IP Inbound Manipulation table.
[0] None (default)
[1] Emergency Only
Notes:
Inbound manipulation applies only to INVITE requests.
For more information on SAS inbound manipulation, see
'Manipulating Destination Number of Incoming INVITE' on page
511.

CLI: configure voip > sas

n
[SASRegistrationManip
ulation]
This table parameter configures the SAS Registration Manipulation
table. This table is used by the SAS application to manipulate the SIP
Request-URI user part of incoming INVITE messages and of incoming
REGISTER request AoR (To header), before saving it to the registered
users database. The format of this table parameter is as follows:
[SASRegistrationManipulation]
FORMAT SASRegistrationManipulation_Index =
SASRegistrationManipulation_RemoveFromRight,
SASRegistrationManipulation_LeaveFromRight;
[\SASRegistrationManipulation]
For example, the manipulation rule below routes an INVITE with
