Let's say, I have extensions 100 and 200 and there are few scenarios that I want to implement: 1) There are two queues. 100 is an agent in one, and the 200 is an agent in second one. At 6:00 I want only one queue being able to receive calls from IVR, let it be queue for 100. At 7:00 I want both of them being able to receive the calls At 8:00 only the second queue being able to receive the calls. 2) Mon-Fri the dialtree follows one IVR Saturday it goes to second IVR. On Sunday and other non-office hours it goes to third IVR. Right now I have to do this through different fake extension, which is gratefully sucks, when you have a lot of settings like that.
