Who called from 3103454166

They called but my phone rang for a half second then stopped!

I got one today with no message - thought it might be a friend who just moved to San Diego - when i called it back I keep getting a message that the circuits are busy. They didn't leave a message.

They called my cell phone while I was working.Did not leave message or anything. When I tried to call the back and my phone said "Call Failed: Not Allowed"

I got a call from this number at work. i tried calling back and it say call failed.

i got a call today at home. Person said they were an operator with an important call and to hold. Put on hold and nothing happened.
