Calls all day. No one speaks.

why did you call me and then hang up without saying anything??

This number calls repeatedly throughout the day and then when you pick up no one responds. Later when you get the phone bill, you get charges from other states for .10 cents ea.

I get several hang up calls a day from this #. When I return the call,  it welcomes me to "audex" or "audix" and requests an extension and a password.Haven't received a bill yet.

Audix or Audex is a centralized voicemail system which some phone companies use for their customers. I just found this out now since I've been getting the same calls and respones you have. Why the system is  dialing out is beyond me, and I'm trying to locate phone companies in the area code 207 that utilize this system to provide answers. Perhaps someone can try this lead and post some answer.
