group members, where if the device uses the alternative route, the call is also sent to
its group members. In this case, instead of setting the alternative route's 'Group Policy'
to None, you must set it to Forking. The group members of the alternative route must
be configured in the rows immediately below it.
The LCR feature can also be employed with call forking. The device calculates a
maximum call cost for each Forking group and routes the call to the Forking group
with the lowest cost. Thus, even if the call can successfully be routed to the main
routing rule, a different routing rule can be chosen (even an alternative route, if
configured) based on LCR. If routing to one Forking group fails, the device tries to
route the call to the Forking group with the next lowest cost (main or alternative route),
and so on. The prerequisite for this functionality is that the incoming call must
successfully match the input characteristics of the main routing rule.

Dial Plan Tags for Representing Source / Destination Numbers: If your
deployment includes calls of many different called (source URI user name) and/or
calling (destination URI user name) numbers that need to be routed to the same
destination, you can employ user-defined tags to represent these numbers. Thus,
instead of configuring many routing rules, you can configure only one routing rule
using the tag as the source and destination number matching characteristics, and a
destination for the calls. For more information. see Using Dial Plan Tags for Matching
Routing Rules on page 751.

Dial Plan Tags for Determining Destination IP Group: Instead of configuring
multiple routing rules, you can configure a single routing rule with a specific
"destination" Dial Plan tag. The device uses the tag to determine the destination IP
Group. For more information, see Using Dial Plan Tags for Routing Destinations on
page 761.
Note:
The following procedure describes how to configure IP-to-IP routing rules through the Web
interface. You can also configure it through ini file (IP2IPRouting) or CLI (configure voip >
sbc routing ip2ip-routing).

To configure an IP-to-IP routing rule:
1. Open the IP-to-IP Routing table (Setup menu > Signaling & Media tab > SBC folder
> Routing > IP-to-IP Routing).
Version 7.2
Call forking is not applicable to LDAP-based IP-to-IP routing rules.
