SIP User's Manual 768 Document #: LTRT-83310
Mediant 600 & Mediant 1000
Parameter Description
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: 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 = 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 (default).
[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 IP2IP 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 Inbound Manipulation
Mode
[SASInboundManipulationMode]
Enables destination number manipulation in incoming INVITE
messages when SAS is in Emergency the state. 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 397.
