28.5.3 SAS Routing Based on IP-to-IP Routing Table
SAS routing that is based on SAS Routing table rules is applicable for the following SAS
states:
Normal, if the 'SAS Survivability Mode' parameter is set to Use Routing Table only in
Normal mode.
Emergency, if the 'SAS Survivability Mode' parameter is not set to Use Routing
Table only in Normal mode.
The SAS routing rule destination can be an IP Group, IP address, Request-URI, or ENUM
query.
The IP-to-IP 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 IP-to-IP 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.
