39.4 Pre-Configured IP-to-IP Routing Rules

Note:
• 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 656.

1. Index 7 appears only if the CRPGatewayFallback parameter is enabled (see
''Configuring PSTN Fallback'' on page 723). This routing rule is used if the device can't
find a matching destination user for IP Group 1 (User-type IP Group) in its registration
database. If the CRPGatewayFallback parameter is disabled and no matching user is
find, the device rejects the call.
