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.

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? Seems like a new kind of toll fraud that international fraud detection systems won't catch. -Paul _______________________________________________ VoiceOps mailing list VoiceOps at voiceops.org<mailto:VoiceOps at voiceops.org> https://puck.nether.net/mailman/listinfo/voiceops<https://shared.outlook.inky.com/link?domain=puck.nether.net&t=eyJ0eXAiOiJKV1QiLCJhbGciOiJFUzI1NiJ9.eJxVj8FqhDAQht8lZ6nidqHrqbTselld6KohQZBoZjE6UTHRSkvfvbG3Moc5zD8z3_dNlhlJRFprJxOVfulPS9M_DWBbmPdW-loo1GIofVTGquExlv46qgbGyRCPWBBaSXdBICqQFhCaUe-DdgZhK4QV3IPAI38pRjcjaNHLuDCcpmt9PwUyLBTr39o63iZOPwJON2ThyV71EeX7y5ZqjknIXJ033rV4i1mQ0FTxrDmk8aXl9KJTWqj07rJZfkwy9pV07Pna5QcHogYL8yAcxEOgAY8sBuYKdq1KSDmDMQ7MfkJdv_6T2PXd_i0n0bAg_vwCqMBoXw.MEUCIB2jh7E6C73ltYGuqw88jHcwEqx1ZKc2yd7sZy-ODrATAiEAmcro0OpNvSV5koUqAgXN88Hv-Yt0-ybonzUAGQI30-I>
