It sounds like someone is dialling the phone while I'm on a call and I'm unsure of what is causing this. I have tried using a different phone with this SIM, resetting the device, turning airplane mode on and off, and no luck. The problem is inconsistent and only happens when I call my wife on the same network (public). I make calls out and never have this issue with anyone else. Hanging up and calling back resolves the issue but I would like to know how to fix this so it just doesn't happen.
Completely lost on this and it has been a really irritating issue.
