I was thinking the same. It probably explains why calling in RIngCentral apps are not working on ios 13 beta currently. I know that RC devs are aware of this so I would hope it is resolved by the time 13 is released.
Hi there! I'm having an issue that I suspect is around iOS 13. I used to be able to call my native iPhone and my work phone at the same time without the call saying "Call Failed." I also have users getting kicked out of Active Calls. Do we have any further info on the iOS 13 piece?
