I'm using 3CX on my iPhone and it works well except the do not disturb function. I have two issues: Do Not Disturb function in IOS (not the function in 3CX): I activate the function planned from 22:00 - 06:00, so I can sleep well and will not be disturbed. This works fine for calls, mails, SMS and so on, but 3CX completely ignores this function, it just rings like hell in the middle of the night Do Not Disturb in 3CX This function works, but I can only choose that it will work for 2 hours or 12 hours, but that's bad. I have to activate the function exactly 12 hours before I want to activate it again. Better would be to set the exact time when it should change back to "available". If I want it activate at 06:00 I have to deactivate it at 18:00 which does not work for me, because I have to be available until 22:00. A scheduler would solve this problem. I'm really unhappy with this situation because there is no solution at the moment. Any ideas or plans for the future to solve this? PS: It's not possible to set the work times striclty from 06:00 to 22:00 because we have more than one really complex ring groups and it seems that 3CX it not designed for that. Edit: On Android phones we can solve it by a scheduler which activate and deactivate airplane mode when I want it. This is something which is not possible on IOS.
