Surely that's true of *any* trunked system, though? Once you've filled up all the traffic channels (or timeslots) it's going to start moaning about being busy.
You don't even need a disaster to do that - stand near a football ground just after a game finishes and everyone is coming out, and try to make a call. The city where I live has just switched all their traffic wardens over to mobile phones - it's a disaster when there's any large event on. The MPT1327 system keeps going without a blip... (well, except when BT cock up the tie lines)
