Version 6.6 685 Mediant 2000
User's Manual 45. Configuration Parameters Reference
Parameter Description
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
[SASEmergencyNumber
s]
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 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
[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
[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
