keep getting a call from these people every day.... at least everyday some times 2. what the hell? who are they? I am no where near IA.

I get called from this number just about everyday on my cell phone it is annoying because sometimes I will answer and nothing on the other side and guess what? that goes on your minutes!!!Somthing must be done about this!!!

They just called, after confirming the number by Googling here on this page, I just picked up the receiver and hung up on them rather than listening to it ringing or actually speaking to them.  Nowadays it seems so many of these solicitor calls come through during the day (on my work phone line), it's easier to just go off hook and hang up rather than even listen to the phone ringing!

7124290352 called at 1432 MST and when our agent answered, they hung up. A quick return phone call yielded in a "number you have dialed has been disconnected..."

I suspect this entity is performing some kind or service or activity that is boardering (or just is) illegal. Monitoring will continue and the FCC will be notified if the pattern continues.
