Another has to do with a station's forwarding being set to Forward All.

The only downside to using the Hunt Group is that it will not present the call to a busy station. If all stations are busy, you won't know someone is at the door. One way around this, as long as you keep it in mind when programming, is to be sure to program one or more "common area" phones, to help increase the odds of there being an idle phone at all times, so you will hear the ringing.

A busy extension will recieve a second call if it has a group intercom to accept it.
