We have a Legend in one of our offices and they would like to have some sort of "night bell" where after 5 pm, incoming calls on the main line will ring all the desks, and if no answer, will flow to the Auto Attendant. Avaya tried to set this up, however, the calls wouldnt flow back to the AA, rather, it would go to the lowest extension's personal mailbox. Avaya said there was no other way to fix this except remove the call forwarding to vm off the phones (and why would anyone do that?). Is there any way to accomplish this? Do we have to run a cable and install a "true" night bell and add a pick up key to the phones? PLEASE HELP?
