My usual trick is to wait a couple of days and look in your category 11 intercarrier compensation files for the call examples and check the CIC field, and if it's all 0's, check the OCN in the file. I'd check your CDR to see if JIP (If this is on your Taqua, you'll want the jurisdictionInfo field) is populated. If it is, you have the NPA/NXX of your originating LEC. -Paul On 09/16/2011 04:21 PM, Matthew S. Crocker wrote:

I'm seeing a lot of calls from 118772988855 hitting my customers. I actually had two hit my home line today simultaneously. It was a 'you could get a better credit card interest rate' scam. The calls came in through my Verizon SS7 interconnect. Does anyone know the source carrier? Any way to track them down.

Thanks
