Who called from 8585350547

An unknown caller but with no available service when I call back..

Just got a call from 858-535-0547 - no one there - hung up before I said hello - tried calling it back and got a "number is out of service" message....

caller hung up when i said hello number cant be connected when call back

rang, no msg. I did not return call.  6:40P san diego

Caller let me say "hello" twice then asked if he could speak to me.  I said "Speaking."  He promptly hung up the phone thereafter.  When I called the number back, the disconnected recording came on.
