Caller leaves a voicemail and hangs up, but vm keeps recording and eventually times out several minutes later. In my area it is always mediacom as the service provider, when a customer has this issue.

Is there a general consensus of the solution to this problem? I've heard that having the cable company change the phone modem out, will fix this. Trying to convince them something is wrong with the phone modem is easier said than done.

But then I wondered if there needs to be a setting change in the phone system, "open loop detect timer", or call disconnect timer, which I have tried at one place and it didn't help.

This seems to be coming up more and more for me.
