User's Manual 35. Configuring Dial Plans
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 New.
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 New.
b. Click the Rule tab, and then configure matching characteristics for the incoming
call (e.g., set 'Source IP Group' 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.
