30.4 Pre-Configured IP-to-IP Routing Rules
For the CRP application, the IP-to-IP Routing table is pre-configured with IP-to-IP routing
rules. These rules depend on the configured Call Survivability mode, as described in
''Configuring Call Survivability Mode'' on page
516 .
Notes:
•
The IP-to-IP Routing table is read-only.
•
For accessing the IP-to-IP Routing table and for a description of its parameters,
see ''Configuring SBC IP-to-IP Routing Rules'' on page
487 .
30.4.1 Normal Mode

Notes:
1. IP Group 1 is a User-type IP Group and therefore, if the devicecan't find a matching
user in the device's registration database, it attempts to route the call using the next
routing rule.
2. Index 7 appears only if the CRPGatewayFallback parameter is enabled (see
''Configuring PSTN Fallback'' on page
520 ).
