facetime not working
Just recently I am no longer able to initiate or answer an incoming Facetime call successfully. When I call my wife's phone it doesn't ring. When she calls me it rings and I accept, it shows my video, but never connects with her. I just tried it with my brother and it rang both ways but would not connect.
I read something where it said that the phones had to be on the same revision IOS so I upgraded my wife's to the current revision and mine was already there. This had not effect on correcting the problem.
Any input on what is going on and how to correct it would be greatly appreciated.
