I have a customer who used to have line 9 on the system ring through the paging speakers after hours when the night button was pushed. Now, for some reason, all lines are ringing through the speakers when the button is pushed. So I actually have 2 ?? - first, what is the programming to have a line ring a loudspeaker, and second, how do I make it so only when the night service button is pushed? I got as far as seeing what extensions are in the night service group - there is one that has a phone and two that they are not using. Any help appreciated. Thanks.
