I have option 1C
Only my extension number (3106) can dial a code (85) to get the outgoing call.
I surprised when I find all the other sets can dial a special cod 51 – 1234 and here another internal tone and then dial (85) to get the outgoing call, how can I cancel this option form all the others sets. And make my set only get the outgoing call.
