Delegation calls: disable ringing on Mobile App Only

[PG-305]

We are about a month away from go-live with Zoom phone. In our testing we’ve found that delegation calls with ring all of the delegatee’s devices, including their mobile phone apps. Has anyone found a way to limit this? My concern is bosses lines ringing on their assistants cell phones at all times, including lunch breaks, after-hours and weekends.

Thank you in advance!
