SIP User's Manual 494 Document #: LTRT-65415
MediaPack Series
Parameter Description
(default).
[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: 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 "".
