Calls worked through Mac and from iPhone and Now Suddenly Don't Work at All

Question

After Monday's update, I was able to make and receive calls through my iPad 3 and iMac (about a year old) with no problems at all. Matter of fact, it was a little annoying to have all three devices ringing whenever I received a call. Then mid-week, this feature did not work at all.
What I've Done:
1) I've gone through the set-up guides and now my FaceTime doesn't even show the option to set-up this feature.
2) I've signed out of FaceTime on both devices multiple times.
3) I signed all the devices in on my iCloud e-mail to ensure they are on the same page.
Now phone number don't even show the option to call when I was freely making phone calls just a few days ago from my Mac, a feature I love. It's as if the settings don't even reflect it's possible to set-up this feature. On the FaceTime settings it doesn't even have the check box for allowing calls to be connected through.
Please help.
