My phone is picking up other people's microphones. Only when I call one number. It only does it while dialing out to a certain number. There is soft clicking on the line when it does ring out. I have checked almost everything on my phone and came to VPN. I have never used it and haven't even heard of it until today. When I first checked it there was an error message and a long log. I checked again and half of it was gone. I checked a minute after that and the log is empty. I have pictures if you can help me I need to find out who this is. Please help!
