3.4.5.7.2 Configuring the IP2IP Routing Table (SAS)
The 'IP2IP Routing Table' page configures SAS routing when SAS is in Emergency mode.
Up to 120 SAS routing rules can be defined. The device routes the SAS call (received SIP
INVITE message) once a rule in this table is matched. If the characteristics of an incoming
call does not match the first rule, the call characteristics is then compared to the settings of
the second rule, and so on, until a matching rule is located. If no rule is matched, the call is
rejected.
Notes:
•
The 'SAS Configuration' page appears only if you have enabled the SAS
application (refer to ''Enabling Applications'' on page
142 ).
•
For a detailed explanation on SAS, refer to ''Stand-Alone Survivability
(SAS) Feature'' on page
479 .
•
For a specific SAS routing rule to be effective, the incoming SIP INVITE
message must match the characteristics configured for that rule.
•
The IP2IP Routing table can also be configured using the ini file table
parameter IP2IPRouting (refer to ''SIP Configuration Parameters'' on
page
318 ).
