Table 1-13: Modified SIP SAS Parameters for Release 6.2
Parameter Description
SAS Survivability Mode
[SASSurvivabilityMode]
Modification: Option [4] Use IP-to-IP Routing Table added (all
products).
Determines the Survivability mode used by the SAS application.
[0] Standard = Incoming INVITE and REGISTER requests are
forwarded to the defined Proxy list of SASProxySet in Normal mode
and handled by the SAS application in Emergency mode (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).
