The lack of ability to choose "IVR" for an "Off-Duty Handler" as part of Business Hours is not optimal, and in my opinion should be a standard feature. This functionality exists within any PBX that I've worked with in the past. Having to forward calls to a separate number in order to alleviate this lack of ability is adding cost through the consumption of minutes.
Please implement the ability to choose IVR as an option for the Business Hours Off-Duty Handler.
Best,
