How do I use the Dial Plan feature to block toll fraud?

Question:  How do I use the Dial Plan feature to block toll fraud?

 

Product and Software: This article applies to ArubaOS 5.0 and later.


Toll fraud is a costly expense for all companies. Long distance carriers will notify users when the activity is detected. In ArubaOS 5.0, you can log this activity and block charge-backs. I have enclosed all the dial-plan syntax in this article example. See the user guide for the full syntax and more examples.
Example
Accounting has noticed a charge of 88 dollars for an 800 number. It has been determined that the users are receiving spam that asks them to call an 800 number, 800-123-1234. For all SIP clients, we can use the dial-plan to change the dial number. You can also forward the number to an IT recorded message.

918001231234. >> 8989%e >> 8989918001231234
In this example, the dial plan adds "8989" to the front of the dial string, and the PBX forwards users to a prerecorded message at extension "8989". The logging for this dial-plan feature also logs additional information of the caller.

Inserting digits (%e = Dialed String)

Insert "9": 9%e

Insert "91": 91%e

Insert "9011": 9011%e

Advanced Syntax

"%e": Variable for the dialed string.

"X": Wildcard for 0-9

"Z": Wildcard for 1-9

"N": Wildcard for 2-9

"[" and "]": Used for a more specific range

".": Wildcard for the remaining digits
