In former GTE territories, this feature is only provided if the lines ordered are trunks. If they are ordered as simple POTS lines, they sometimes don't add this feature arbitrarily. You have to ask for it. I had luck in getting their repair people to understand what this feature was and to put it on. They refer to the feature as "cancel on disconnect". If you are in a former Bell Atlantic area, then I really don't know what to tell you except to try the same thing with repair people.

This is not a feature that incurs a monthly fee.

You are fortunate to have two lines that work properly and two that don't so that they can do a complete comparison between them. That's better than most people get.
