Who called from 8585643148

Caller called around dinner time. I didn't answer. The caller left no message.

i don't answer anymore.  They never speak and don't leave a message

I don't answer numbers I don't recognize, but I did dial this number back using *67 to hide my own caller ID. It was answered by a 'singing' message asking me to leave my name & number. I have gotten this message a dozen times from many different numbers. I believe it to be a telemarketer and they are now blocked.
