CHAPTER 25 Routing SBC
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 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
for Matching Routing
■ 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
■ Fax Rerouting: You can configure the device to reroute incoming calls that it identifies as fax
calls to a new IP destination. For more information, see
Destinations.
Call forking is not applicable to LDAP-based routing.
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).
2. Click New; the following dialog box appears:
3. Configure an IP-to-IP routing rule according to the parameters described in the table below.
4. Click Apply.
