I can confirm we?ve seen fraud to this NPANXX also on our carrier network. In our case, a customer PBX was hacked and all of their call paths were filled with never-ending calls to random numbers in this exchange. In our case also, all calls answered with dead air. The calls stayed up until we killed them. Most LD companies don?t seem to terminate to this exchange at all, but Level 3 did for a high price. That was expensive; we had assumed that the FCC?s ICC reform had done away with high-cost domestic destinations. We block this NPANXX now, and have never had a complaint about it being blocked.

Jumping in on this one late ? Pine Ridge is most well-known for the Ogala Lakota reservation that is located there. Numbers are in fact owned by Native American Telecom which is tribally owned and has had traffic pumping charges levelled against them as someone else mentioned. Payday lenders have used tribal law for years to get around usury laws, there was one company that was charging something like 900% effective interest. Repayment on a $10k loan was something like $75k. Wondering if they can somehow skirt Federal telecom law too? Paul, you are 100% correct ? any fraud detection system that is only looking at International destinations would not pick it up . . . you definitely need something that can, at a minimum, be configured to look at call velocity and volume to US destinations. I can make a recommendation if you are interested.

Yeah, what makes it notable in this case is it seems like it's dead air calls and hacked phones like traditional international fraud, not free conference call services.

Paul, Why do you mention international toll fraud when that is an area code and exchange for Pine Ridge South Dakota? And just imagining how small that company must be wouldn't a logical guess be more like they just messed up in some fashion? But in your defense that telecom company is fishy and Sprint tried to sue them. I am not sure what ended up happening. Typical crap with free conf stuff and having traffic sent to a high cost area...

Is anyone else seeing lots of long duration calls to the 605-562 exchange that when you dial the respective number, it supervises to dead air?
