Thanks for your reply, but it gets more complicated. The system has 3 DLC's that are in a calling group(780). Ext 143 is logged in to the group most of the time, but if she goes to lunch, she can log out and have one of the other DLC's log in. 12 CO lines are assigned to the calling group(780). There are also 12 channels of two way coming in on a T1. The only digits sent on incoming are 899. These are unassigned. If I send unassigned to group 780, it works great in the day, but in night mode it rings to an open. If I send them to VM(7929) they go to the AA all the time. If I send them to Ext 143, They follow the night service button, but in the daytime, they go to Ext. 143's personal MB. How can I get them to go to the Group 780 in the day, and Group 7929 at night?
