Who called from 3072151004

this number called my office voicemail at 8pm mountain time on a Friday -- no message

I should have mentioned in my earlier post that a caller must enter two separate extension numbers after dialing to reach my voicemail

I got a call from this number yesterday.  They did not leave a message.  When I tried calling it back, I got a message saying the number had been disconnected!

Got a call from this number last night around 8, no message.

Called at least 4 times, no messages left on machine. When I call back, it says the number has been disconnected.
