When in Meetings to Block ALL incoming phone calls Merged

An automatic change in user status to Do not Disturb (DND) when the user has a booked meeting in their calendar - whether the meeting is a physical meeting or an online meeting.
This feature needs to work and integrate with the following most used platforms:· RC Meetings· Microsoft Teams - Office 365· Skype· Other popular system that may be used by other organizations
At the moment when I am in a Teams Meeting online - phone calls still come through and its very distracting. Having to switch your status to DND manually is a painful exercise as I also tend to be pulled into meeting unexpectedly - all meetings are booked via the Calendar. The system should be able to automatically recognize that I have a meeting and therefore would be unable to answer ANY phone calls.
