A university professor has worked out a low-tech way of preventing students' mobiles from going off in class: he answers them himself.
Peter Telep, at the University of Central Florida, has taken calls from his students' boyfriends and girlfriends, telling them: "This is the English teacher, and we're busy right now."
The professor warned students of his novel approach on the first day of term, and told the Orlando Sentinel newspaper that he no longer has a problem with phones going off during his classes.
University lecturers are apparently finding mobile phone use so frustrating that they are having to develop ever more imaginative ways to cope.
Some have more serious rules: students have been told to leave the class, and some have even had their grades reduced.
