Some kind of computer modem or FAX tones on our voice only line that left us a voicemail that lasted for 83.5 minutes. Really? What F***ing FAX tries for more than 2 minutes to connect? I bet 100% this came through on our toll free # so we will be paying the charges for the call as well. What BS. I bet it's the Toll Free companies sending these calls through to make us pay more. It wouldn't be a first as the TF providers have been caught doing this before (Google it). Each time we get these calls it is on a new number. I called the number and left a VM on their system asking for any explination they could provide (may not be them, could be a spoofed #). I will update you when I know more...
