SIP User's Manual 6. Configuration Parameters Reference
Parameter Description
Web: Redundant SAS Proxy Set
EMS: Redundant Proxy Set
[RedundantSASProxySet]
Determines the Proxy Set (index number) used in SAS
Emergency mode for fallback when the user is not found in the
Registered Users database. Each time a new SIP request arrives,
the SAS application checks whether the user is listed in the
registration database. If the user is located in the database, the
request is sent to the user. If the user is not found, the request is
forwarded to the next redundant SAS defined in the Redundant
SAS Proxy Set. If that SAS Proxy IP appears in the Via header of
the request, it is not forwarded (so that loops are prevented in the
request's course). If no such redundant SAS exists, the SAS
sends the request to its default gateway (configured by the
parameter SASDefaultGatewayIP).
The valid range is -1 to 5. The default value is -1 (i.e., no
redundant Proxy Set).
Web: SAS Survivability Mode
EMS: Survivability Mode
[SASSurvivabilityMode]
Determines the Survivability mode used by the SAS application.
ƒ
[0] Standard = All incoming INVITE and REGISTER requests
are forwarded to the defined Proxy list in SASProxySet in
Normal mode and handled by the SAS application in
Emergency mode (default).
ƒ
[1] Always Emergency = The SAS application does not use
Keep-Alive messages towards the SASProxySet and instead,
always operates in Emergency mode (as if no Proxy in the
SASProxySet is available).
ƒ
[2] Ignore REGISTER = Use regular SAS Normal/Emergency
logic (same as option 0) but when in Normal mode, incoming
REGISTER requests are ignored.
Web: SAS Binding Mode
EMS: Binding Mode
[SASBindingMode]
Determines the SAS application database binding mode.
ƒ
[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).
ƒ
[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.
