I have around 10 extensions ringing dial "0". Dial "0" is ringing over to phantom extension 500. My problem is that the customer is wanting to push a night button and wants more phones to start ringing dial "0". Then turn night off and go back to the same 10 phones. I can`t think of a way to do so if some one has some advise it would be appreciated. (Toshiba 280,B processor,release 3)(Stratagy DK 4 port card)
