Who called from 2087580237

Just got the call but didn't answer it.  My Caller ID reads:  Coeur D Alen ID
A Phone Stalker

208-7580237 called me at 7:25. i picked up and it was just silence, My mom got a phone call from a 208 area code 30 mins before me

I also received a call from this number. From Idaho, and when I attempt to call back I just get a busy signal.

I was called twice from this number on july 5 2010 at 7:21... when I attempt to call back I just get a busy signal 3 times in a row! Strange!

I got this call on landline and cell.  I picked up the land line and it was a recorded political survey.  I did not find out who is behind it...The message had already started rolling and the information identifying what the call was about (if they did id) was missed.   Calls were received on July 19th on landline and july 21 on cell.
