Implement a Disable Call Blocking Feature

Implement a feature on admin portal to fully disable call blocking for users either by user, group, role, site or company wide. Users can still block calls in the phone app under history (even if role is setup with the Screening, Greeting & Hold Music unchecked (which blocked calls is a subset of)). This way the control is on the admin users and end users would not be able to use or change that feature unless admin portal settings are updated.
