I got a call from my parents who told me that when someone calls their home phone number, it answers with what sounds like a fax. I tried it and sure enough, it was being answered by a modem. My first thought was the security system, or even their fax, but no. The fax is on a separate line, but I was grasping at straws. I disconnected everything in the house and it rang just fine with no answer. Their answering machine was picking up after five rings, which is when the modem tone was heard. I later found that ANY device that answered the line would result in this tone. It turns out that the new EMTA that Spectrum is using, made by 'Ubee' was the culprit. Once the line is answered, it turns itself into a modem and takes over the line. A hard reboot of the EMTA resolved this, but it was definitely a first for me.
I won't go into the numerous times they spent on the phone with Spectrum being told that the problem was with their phone "system".
