Moreover, on these switches, you can get a loop-drop even if you don't have call-waiting. If the party you're conversing with on an intra-office call has call-waiting and gets beeped, you get a loop interruption while he or she gets beeped. But on 5ESS, you get a beep, the other end gets nothing, and nobody gets an open-loop. Either the switch is not a 5ESS, or the problem isn't call-waiting.
