b. Configure routing rules using the one or both of the following fields for specifying
the tags:
♦ 'Destination Phone Prefix': Prefix tags for called number prefixes: For
example, configure two routing rules:
Configure the field to "LOCL" and the 'Trunk Group ID' field to 1 (local
Trunk Group).
Configure the field to "LONG" and the 'Trunk Group ID' field to 2 (long
distance Trunk Group).
♦ 'Source Phone Prefix': Prefix tags for calling number prefixes.

5. Configure manipulation rules to remove the prefix called tags:
a. Open the Destination Phone Number Manipulation for IP-to-Tel Calls table (see
''Configuring Source/Destination Number Manipulation'' on page 537).
b. In the 'Destination Prefix' field, enter the prefix called tag (e.g., "LOCL").
c. In the 'Stripped Digits From Left' field, enter the number of characters in the prefix
called tag (e.g., "4").
6. Configure manipulation rules to remove the prefix calling tags:
a. Open the Source Phone Number Manipulation for IP-to-Tel Calls table (see
''Configuring Source/Destination Number Manipulation'' on page 537).
b. In the 'Source Prefix' field, enter the prefix calling tag.
c. In the 'Stripped Digits From Left' field, enter the number of characters in the prefix
calling tag.
45.5.4 Obtaining IP Destination from Dial Plan File
You can use a Dial Plan index listed in a loaded Dial Plan file for determining the IP
destination of Tel-to-IP and SBC (see note below) calls. This enables the mapping of called
numbers to IP addresses (in dotted-decimal notation) or FQDNs (up to 15 characters).
Note: For the SBC application, the method described in this section for obtaining an
IP address using the Dial Plan file is for backward compatibility purposes only. For the
new method, see Configuring Dial Plans on page 726.
To configure routing to an IP destination based on Dial Plan:
1. Create the Dial Plan file. The syntax of the Dial Plan index for this feature is as
follows:
<destination / called prefix number>,0,<IP destination>
Note: The second parameter "0" is not used and ignored.
An example of a configured Dial Plan (# 6) in the Dial Plan file is shown below:
[ PLAN6 ]
200,0,10.33.8.52 ; called prefix 200 is routed to
10.33.8.52
201,0,10.33.8.52
300,0,itsp.com ; called prefix 300 is routed to itsp.com
2. Convert the file to a loadable file and then load it to the device (see ''Creating a Dial
