Got a call today from 503 201 2304. Let it go through the message, and it gave menu options, so I entered "1", and was connected to a (live) person selling something, I think it was insurance of some sort. Cursed her out and hung up. Looked at my cell call log, I had gotten a call from 503 200 9482 several weeks ago; I imagine it's another number they call from. Since there is a real person available at the number, I suggest letting it give you the option of talking to them, get as much info as possible, and use it against them in any way you can.
This same number has been calling me on and off for about a month now. Try to call it back and it toss busy.......the wierd thing is i just moved to Portland from Texas....and i still have a Texas area code...i do.t give my number out either.
