This person keeps calling and hangs up when we answer.

This number called twice today! First time I left it goto voicemail and it hung up right away. Later that evening when it called I picked up and it hung up right away once again! When you call the number back the recording states that the number is no longer in service.
My thoughts: This may be a computer set up to figure out what phone numbers are active and what numbers are connected to a fax machine. They use this info to sell to companies to send un-wanted telemarket calls and faxes. ie: inforusa.com or faxblast.com
I have had many issues with them in the past selling my number. I would get faxes at all hours of the night to a phone line which was my home phone number.

If anyone obtains additional info I would be greatful if you could pass it on to me!

Got more information on this number!
The phone number comes out of Easton, Pa. which is half way between Philly and Reading, Pa. where I live. The number is owned by the below phone company. I am going to contact them tomorrow. Anyone else that gets this number calling them and hanging up etc I suggest reporting it to this phone company asap. If the company is legit they tend to do something about these things. Anyways here is the info!

ATX Communications.
