Version 6.8 371 Mediant 2600 E-SBC
User's Manual 21. SBC Configuration
Consider Inputs. The alternative route can also be configured with its own forking
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 Prefix 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 prefix tags to represent these numbers.
Thus, instead of configuring many routing rules, you need to configure only one
routing rule using the prefix tag as the source and destination number matching
characteristics, and a destination for the calls. For more information on prefix tags, see
''Dial Plan Prefix Tags for SBC IP-to-IP Routing'' on page
434.
Note: Call forking is not applicable to LDAP-based IP-to-IP routing rules.
The following procedure describes how to configure IP-to-IP routing rules in the Web
interface. You can also configure IP-to-IP routing rules using the table ini file parameter,
IP2IPRouting or CLI command, configure voip > sbc routing ip2ip-routing.
To configure an IP-to-IP routing rule:
1. Open the IP-to-IP Routing Table page (Configuration tab > VoIP menu > SBC >
Routing SBC > IP-to-IP Routing Table).
