Who called from 2067773656

Phone rang only 4 times and they hung up. I don't know anyone in Washington state.

its a scam if its importannt or someone u know , they will leave a msg

No one answered. And i am in WA state but in the 509 area code.

Keeps calling but nothing on line when I answer...several times over past two weeks, sometimes three-four consecutive times.

caller ID said: Washington and 206-777-3656 -- answering machine took call, they listened to message, and for several seconds after the beep I could tell I still had an open line.  No one spoke, then disconnected.

I never answer unless I know the number and/or name.  If a business I must know the name, and have reason to get a call from them -- I usually just listen until they leave a message and then pick up if it is a legit call,
