Who called from 2145860333

I didn't pick it up, was busy when it rang.  They did let it ring off the hook for over a minute so I thought it might be important.  Googled it, and called back, and got an automated message that said operator 888 was not available and to leave a message.  -.-  Sounds like someone's running a scam.

insounded like a  30 year old man somewhere in there and all he said was hello and then hung up??
