Who called from 4084588585

Called.  I answered as from 408 (local to me).  Nobody for a few seconds then somebody came on the line but was apparently talking to somebody else.  They hung up in about 15 seconds.

I called it back and the caller was "unavailable at this time, please leave a message".  I did not leave a message.

CALLED AND PHONE RANG FOR ABOUT A MINUTE. NO MESSAGE

This number called me twice within 30 seconds. First time I answered but it hang up.  Second time I didn't answer it hang up itself after ringing once.  Very strange.

Call twice within 1 minute, didn't pick up didn't leave message.

Called but left no VM
