Apple introduced the Continuity feature with OS X Yosemite that lets you field phone calls and text messages from your iOS devices and Mac. I enjoy being able to respond to texts from my MacBook Pro and iPad when my iPhone is charging, but I'm less sold on sharing phone calls between all three devices. I don't like the cacophony of ringtones when all three devices are nearby, and I find that even when it's charging, my iPhone is never too far away that I can't grab it to take a call.
In his post about using Continuity to make and take calls, Jason Cipriani explains how to set up the feature and how to disable it on your Mac. I have followed my colleague's directions so my Mac doesn't ring anymore when I get a call, but I also want to disable the feature on my iPad. If you would like to stop your iPad from ringing when someone calls your iPhone, it's easy. Here's how:
Go to Settings > FaceTime and tap the toggle switch to turn it off for Calls from iPhone.
