My phone calls are not working after IOS 9 update

My number shows up as my wife's and hers as mine? Weirdest thing ever? Not sure what's going on?

hate that this is the case, but you are not alone in this.

I had the problem, rebooted, and it went away.

I am having the same problem. People keep calling me and with the screen is off the phone doesn't ring.

I swipe my phone to login and it says I have missed calls and have voicemails.

I turned the ringer on same issue.

Is anyone else having these types of problems?
