Who called from 2064456049

I did not answer the phone when this call came in, but the weird thing was that the rings were very short.  Has anyone else had this happen?

I got 2 calls today  rang twice  I do not know anyone in Seattle

Receive this call today only rang a couple of seconds so caller id could not pick it up. Let me guess, yet another junk debt buyer trick to get you to answer or return call. Portfolio Recovery shame on you!

Phone rang at 10:04 pm. two times.   Caller ID showed this number only as Seattle WA.  
Phoned number back and there is a recording stating, "If you do not wish to receive future calls on promotional specials please press 1 to be placed on our DO NOT CALL LIST-allow 72 hours for this to take place.  Pressed 1 and received auto anwser of thank you.
Not sure if there will be any future problems or not.

got the call. called back pressed 1 to be taken off list, hope it works...
