How can I disable the "Ring my mobile simultaneously" feature system wide ?

Select all your extensions and hit the "Edit" button. Then navigate to the "Forwarding rules" and disable the option "Ring my mobile simultaneously". There is no way to disable the functionality completely so users will be able to reenable it.
