Alex, Thanks for the reply but I've tried everything. If you read my original post I indicated that the problem is only with outgoing calls from my Macbook pro using the audio feature of Facetime. I use this feature all the time and suddenly the other day after installing ios13 I get call failed. I can receive audio calls but not send them. No settings were changed that could cause the failure. It works with my iPad but not my Macbook pro. I have since tried a different iphone and I can make outging calls which leads me to believe that something happened in the install of ios13..
