How to disable call notification on multiple devices? Whenever I receive a phone call, my phone starts ringing (which is fine) and one second later, my iPad and Mac starts to ring as well.

How do I disable or, at least delay the notification of phone calls to my other  devices?

My devices are on iOS 8.1 and OS X Yosemite.
For Mac:


Open the “FaceTime” application on the Mac
Pull down the FaceTime menu and choose “Preferences”
Under the primary Settings tab, uncheck the box for “iPhone Cellular Calls”
Quit FaceTime


For iPad:

Settings->Facetime->iPhone Cellular Calls on the iPad.
