True or False? Hunt Groups are used
"The problem is, when a call comes into the phone system it doesn't go straight to the handset, it is directed towards another group in the system. So when a call comes in, it doesn't call the handset straight away, it calls this group in the system, and because of this, you can not call forward external calls from the handset. If you were to call the handset directly (not even sure if it has an external number), the call forwarding would work."
