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)..so 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.
