3.3.2.13.2 Configuring IP2IP Routing Table (SAS)
The 'IP2IP Routing Table' page allows you to configure up to 120 SAS routing rules (for
Normal and Emergency modes). 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 do
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.
When SAS receives a SIP INVITE request from a proxy server, the following routing logic
is performed:
a. Sends the request according to rules configured in the IP2IP Routing table.
b. If no matching routing rule exists, the device sends the request according to its SAS
registration database.
c. If no routing rule is located in the database, the device sends the request according to
the Request-URI header.
Note: The IP2IP Routing table can also be configured using the ini file table
parameter IP2IPRouting (see SIP Configuration Parameters).
¾ To configure the IP2IP Routing table for SAS:
1. In the 'SAS Configuration' page (see ''Configuring Stand-Alone Survivability'' on page
216), cli
ck the SAS Routing Table button; the 'IP2IP Routing Table' page
