How can I set up the opening hours and holidays?

You can configure the opening hours and holidays in the “Numbering and incoming config” section by clicking on the “Edit” button of the desired configuration > Schedules (calendar icon).

In this tab you will find three main sections: time schedules, holidays and vacations. If an incoming call arrives after hours or on a holiday, the call will be hung up or forwarded to the general answering machine (if activated).
