19.2.5.3 SAS Routing Based on SAS Routing Table

SAS routing based on rules configured in the SAS Routing table is applicable for SAS in
the following states:

SAS in normal state, if the SASSurvivabilityMode parameter is set to 4

SAS in emergency state, if the SASSurvivabilityMode parameter is not set to 4
The SAS routing rule destination can be an IP Group, IP address, Request-URI, or ENUM
query.
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
