my answering machine does not disconnect when caller hangs up

The previous discussion by this name describes a problem shared by many Cox customers, including me. After days of group confusion, Colleen D did something to help ONE PERSON and then the forum was locked (why?). I think it is pretty obvious that Cox has a timing bug that in some cases will cause a delay in disconnect that is longer than the time to connect their muy annoying message - so the voltage never drops and the phone stays on the line. This happens when a telemarketer has a robot that disconnects upon sensing voicemail.They need to fix this for everyone by leaving more time between disconnect and message. I hope that each person who needs their cut-off on disconnect tweaked doesn't have to either independently wrestle their way through tech support or make their own post. Has anyone found an easy, routine way to get the right person to fix this problem? This is complicated by the extreme loudness of the Cox message, which actually damaged the speakers in my previous phone. Why would Cox set this up to blast for minutes on end when all they need to do is cut off the connection themselves after a reasonable time of 20 seconds or so. It is their own robot that makes the problem worse!
