Project Description

We have an increasing problem with toll fraud.
Do you have a solution to combat it?

I have some ideas which we can use Asterisk or other to block the calls or IPs.

Toll fraudsters have this pattern (amongst others):
1- same number multiple times simultaneously
2- similar prefixes in quick succession

We need to:

1- not allow the same number to be dialed concurrently for more than set number of times (say 3) no calls can be made to the same number simultaneously 3 times.

2- asterisk to detect the same set prefix being dialed 5 times in a row within 5 seconds of each other

3-in the dialing rules, enter a dial rule such as block, via a 3rd party application (website) via API

4- asterisk block an IP from registering or transmitting a call. currently we use IPTABLES, but we need asterisk sql to have a list of IPs within it to block them from calling.

5- as in point 4, we need an API designed to add these bad IPs so it can be blocked.

If you have a better idea or solution and a price on the above solution, please bid.

Thank you
