They called and there was a funny sound.  It was not like anything I have heard before, and not a fax. Then they hung up.

Called my home. I didn't pick up.

This number called my home and didn't leave a message.  There was a funny sound while I was waiting for the message, and then they hung up.  I live in Olympia, WA.

Received a call from this number (ID displayed Port Ludlow WA) and there was nothing. I did not hear a funny sound like some have reported but then again my hearing ain't too good.

ID as Port Ludlow WA. I answered. Caller hung up.
