CHAPTER 20 SIP Definitions
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.
The following figure displays the device's SIP dialog processing when Dial Plan tags are used to
determine the destination IP Group:
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
Name
Prefix
Tag
