I had an issue where I would get call drops only when you were using mobile data on iPhone and Android to place a call. This would also happen when using the OS X soft phone app tethered to a mobile phone.
in examining the logs of the IOS app in Xcode, I could see that the call via and Contact fields were showing 127.0.0.1. this caused the other side to not be able to respond properly. I was getting audio, but I think It was trying to connect back and it couldn’t
