here is what I have discovered so far, please paste your call records and perhaps we can complete a better black list.

Thank your for your reply,
I have a small question. How to block for these prefixes in rate card A2Billing ? Because I add rate for Myanmar with prefix : 95xxxxxxx .So all calls to Myanmar can pass through A2Billing.
In my case, these numbers that they make these calls to a dummy trunk are :
Code:
Myanmar - 9552580657
Myanmar - 9552580694
Myanmar - 9552580658
Myanmar - 9552580656
Italy - 393276874424
Thank in advance for all helps!
Best regards,
Ryan.
1. create a dummy trunk with a dummy ip without failover
2. add these prefixes to that.
but yours is a little odd to crack, most of the attack to my servers were into none existing providers or number that somehow a backbone provider would benefit
in your case according
https://www.numberingplans.com/?page=pl ... ent_page=9the number 95-52-58XXXX falls in no city
the nearest valid city is 95-52-50XXXX and 95-52-58XXXX
it's a little difficut job to crack but we need the full list of numbering plan from
https://www.numberingplans.com/?page=pl ... ent_page=9to create a list of world's valid prefixes and take out everything else.
