You configure prefix tags in the Dial Plan file, using the following syntax:
[ PLAN<index> ]
<prefix number>,0,<prefix tag>
where:

Index is the Dial Plan index

prefix number is the called or calling number prefix (ranges can be defined in
brackets)

prefix tag is the user-defined prefix tag of up to nine characters, representing the prefix
number
Each prefix tag type - called or calling - must be configured in a dedicated Dial Plan index
number. For example, Dial Plan 1 can be for called prefix tags and Dial Plan 2 for calling
prefix tags.
The example Dial Plan file below defines the prefix tags "LOCL"and "LONG" to represent
different called number prefixes for local and long distance calls:
[ PLAN1 ]
42520[3-5],0,LOCL
425207,0,LOCL
42529,0,LOCL
425200,0,LONG
425100,0,LONG
....
Note: Called and calling prefix tags can be used in the same routing rule.
The following procedure describes how to configure IP-to-Tel routing using prefix tags.

To configure IP-to-Tel routing using prefix tags:
1. Configure a Dial Plan file with prefix tags, and then load the file to the device.
2. On the Routing General Parameters page (Configuration tab > VoIP menu > SIP
Definitions > General Parameters), specify the Dial Plan indices (e.g., 1) where you
configured the prefix tags:
•
Prefix tags for called number prefixes: 'IP-to-Tel Tagging Destination Dial Plan
Index' parameter
•
Prefix tags for calling number prefixes: 'IP-to-Tel Tagging Source Dial Plan Index'
parameter
3. Open the Inbound IP Routing table (Configuration tab > VoIP menu > GW and IP to
IP > Routing > IP to Trunk Group Routing).
a. From the 'IP-to-Tel Routing Mode' drop-down list, select Route calls before
manipulation so that the device performs the routing processing before
manipulation.
b. Configure routing rules using the prefix tags as matching characteristics for
destination or source number prefixes:
♦
User's Manual
Prefix tags for called number prefixes: 'Dest. Phone Prefix'. For example,
configure two routing rules:

Set this field to "LOCL" and the 'Trunk Group ID' field to 1 (local Trunk
Group).

Set this field to "LONG" and the 'Trunk Group ID' field to 2 (long
distance Trunk Group).
