No message left, just voices in background.

Called 4 times on a phanton voice mail at work and every time hung-up.

Keeps calling my work number.. no noise, just an empty VM in my in-box.. 2 or 3 times in the last week.. kinda annoying..

They keep calling my work number and never leave a message. I called the number but got a message that their voicemail box was full.
The number is in Redondo, CA.

I finally answered this call and it was the Minneapolis StarTribune calling to get me to subscribe to the newspaper.
