Figure 37-7: SIP Dialog Handling for Tag-Based Routing
The following procedure describes how to configure routing to destination IP Groups
determined by Dial Plan tags. The procedure is based on the following example scenario:
Calls from IP Group "HQ" with destination (called) prefix number 102 are sent to IP Group
"ENG" while calls with destination prefix number 103 are sent to IP Group "BEL". The
destination IP Groups are determined by the Dial Plan tags, where the tag
"Country=England" is used to send calls to IP Group "ENG" and the tag "Country=Belgium"
is used to send calls to IP Group "BEL".
To configure routing to destination IP Groups based on Dial Plan tags:
1. In the Dial Plan table, configure a Dial Plan with Dial Plan rules, where the 'Prefix'
parameter is the destination (called) prefix number. In our example, we will configure
a Dial Plan called "Dial Plan 1" with two Dial Plan rules:
Parameter Index 0 Index 1
