Obtaining Ip Destination From Dial Plan File - AudioCodes Mediant 800B User Manual

The following procedure describes how to configure IP-to-IP routing using prefix tags.

To configure IP-to-IP routing using prefix tags:
1. Configure a Dial Plan file with prefix tags, and then load the file to the device.
2. Add the prefix tags to the numbers of specific incoming calls using Inbound IP-to-IP
Manipulation rules:
a. Open the IP to IP Inbound Manipulation table (Configuration tab > VoIP menu >
SBC > Manipulations SBC > IP-to-IP Inbound), and then click Add.
b. Click the Rule tab, and then configure matching characteristics for the incoming
call (e.g., set 'Source IP Group ID' to "1").
c. From the 'Manipulated URI' drop-down list, select Source to add the tag to the
calling URI user part, or Destination to add the tag to the called URI user part.
d. Click the Action tab, and then enter the Dial Plan index for which you configured
your prefix tag, in the 'Prefix to Add' or 'Suffix to Add' fields, using the following
syntax: $DialPlan<x>, where x is the Dial Plan index (0 to 7). For example, if the
called number is 4252000555, the device manipulates it to LOCL4252000555.
3. Add an SBC IP-to-IP routing rule using the prefix tag to represent the different source
or destination URI user parts:
a. Open the IP-to-IP Routing table (Configuration tab > VoIP menu > SBC >
Routing SBC > IP-to-IP Routing Table), and then click Add.
b. Click the Rule tab, and then enter the prefix tag in the 'Source Username Prefix'
or 'Destination Username Prefix' fields (e.g., "LOCL", without the quotes).
c. Continue configuring the rule as required.
4. Configure a manipulation rule to remove the prefix tags before the device sends the
message to the destination:
a. Open the IP to IP Outbound Manipulation table (Configuration tab > VoIP menu
> SBC > Manipulations SBC > IP-to-IP Outbound), and then click Add.
b. Click the Rule tab, and then configure matching characteristics for the incoming
call (e.g., set 'Source IP Group ID' to "1"), including calls with the prefix tag (in the
'Source Username Prefix' or 'Destination Username Prefix' fields, enter the prefix
tag to remove).
c. Click the Action tab, and then in the 'Remove from Left' or 'Remove from Right'
fields (depending on whether you added the tag at the beginning or end of the
URI user part, respectively), enter the number of characters making up the tag.

39.1.4.4 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 /IP-to-IP and SBC calls. This enables the mapping of called
numbers to IP addresses (in dotted-decimal notation) or FQDNs (up to 15 characters).

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
10.33.8.52
201,0,10.33.8.52
