3. In the IP-to-IP Routing table (see Configuring SBC IP-to-IP Routing Rules on page
671), configure a routing rule with the required destination and whose matching
characteristics include the tag(s) that you configured in your Dial Plan in Step 1. The
tags are assigned under the
Match group, using the following parameters:
•
'Source Tags' parameter (IP2IPRouting_SrcTags): tag denoting the calling user
•
'Destination Tags' parameter (IP2IPRouting_DestTags): tag denoting the called
user
39.3.2 Using Dial Plan Tags for Routing Destinations
You can use Dial Plan tags for determining the destination (IP Group) of an IP-to-IP
Routing rule. One of the benefits of using Dial Plan tags is that it can reduce the number of
IP-to-IP Routing rules that you would normally need to configure. For example, assume
that you need to route calls from IP Group "A" to two different IP Groups, "B" and "C",
based on called (destination) prefix number (e.g., 102 and 103). When not using Dial Plan
tags, you would need to configure two IP-to-IP Routing rules, where one rule sends calls
with prefix number 102 to IP Group "B" and another rule sends calls with prefix number 103
to IP Group "C". However, when using Dial Plan tags, you would need to configure only a
single IP-to-IP Routing rule whose destination IP Group is based on a Dial Plan tag.
The following briefly describes the process for using Dial Plan tags in IP-to-IP Routing
rules:
1. The device searches the Dial Plan Index, associated with the source IP Group of the
incoming SIP dialog, for a Dial Plan rule whose 'Prefix' parameter is configured with
the same called prefix number as the SIP dialog (e.g., 102). If found, the device
inspects the tags in the 'Tag' parameter (e.g., "Country=England;City=London;Essex")
configured for that Dial Plan rule.
2. The device searches for a matching rule in the IP-to-IP Routing table and if the
'Destination Type' parameter is configured to
Destination Tag , it checks the tag name
configured in the 'Routing Tag Name' parameter and compares it with the tags found
in the Dial Plan rule. If the 'Routing Tag Name' parameter is configured as "default",
the device selects the first tag name in the Dial Plan rule that is configured without a
value, for example, "Essex" (see Step 1). If the 'Routing Tag Name' parameter is
configured with a specific tag name (e.g., "Country"), the device selects the tag name
with its value (e.g., "Country=England") in the Dial Plan rule.
3. The device searches the IP Groups table and IP Group Set table for an IP Group
whose 'Tags' parameter is configured with the same tag as selected from the Dial Plan
rule. If found, the device routes the call to this IP Group.
