The functionality of Nokia 22 loop interruption and polarity reversal features is implemented the way described in the question/comment. To make it work properly in every wished and different kind of customer case, Nokia 22 would require quite some further development.
We've made an acknowledment of these comments and have them in mind to assess the issues in possible future development cases.
