If Mr. Baylin indeed is served by a 5ESS switch, then the loop current is NOT interrupted to provide a call-waiting indication. In a 1ESS they couldn't figure out how to put tone plant on an off-hook line without the battery going berserk, so the interruption was necessary on those switches. The #5 doesn't exhibit this behavior; the transition is smooth and almost unnoticeable. Feature or bug: you be the judge. Notwithstanding all the suggestions, I maintain that the best solution to any call-waiting problem is to CANCEL the damned 'feature'!
