Configuring IP-to-Tel Routing Rules

The IP-to-Tel Routing table lets you configure up to 120 IP-to-Tel routing rules. IP-to-Tel routing
rules route incoming IP calls to Trunk Groups. The specific channel pertaining to the Trunk Group to
which the call is routed is determined according to the Trunk Group's channel selection mode. The
channel selection mode can be configured per Trunk Group (see
or for all Trunk Groups, using the global parameter ChannelSelectMode.
Configuration of IP-to-Tel routing rules includes two areas:
■ Match: Defines the characteristics of the incoming IP call (e.g., source IP address from which
the call is received).
■ Action: Defines the action that is done if the incoming call matches the characteristics of the
rule (i.e., routes the call to the specified Tel/Trunk Group destination).
The device searches the table from top to bottom for the first rule that matches the
characteristics of the incoming call. If it finds a matching rule, it sends the call to the Tel destination
configured for that rule. If it doesn't find a matching rule, it rejects the call.
If an IP-to-Tel call cannot be routed to the Trunk Group, the device can route it to an alternative
destination:

■ To implement LCR and its Cost Groups, the Routing
Policy must be enabled for LCR (see
Gateway Routing Policy
device ignores the parameter.
■ The Routing Policy also determines whether matched
routing rules that are not assigned Cost Groups are
considered as a higher or lower cost route compared to
matching routing rules that are assigned Cost Groups.
For example, if the 'Default Call Cost' parameter in the
Routing Policy is configured to Lowest Cost, even if the
device locates matching routing rules that are assigned
Cost Groups, the first-matched routing rule without an
assigned Cost Group is considered as the lowest cost
route and thus, chosen as the preferred route.
