Facetime does not ring on ipad
When I call my parents ipad2 from my ipad2 via facetime, their ipad does not ring. It only shows that i am calling them. Once we connect, everything is fine (audio and video), so it is not an internet connection issue and it is not because their volume is low or on mute. Any ideas why my ipad2 has an audible ring but theirs does not?
We also tried a solution that was posted online that suggested setting the mute button from "lock screen" to "mute" and then sliding the button left and right. This did not solve the problem. Their facetime still does not ring on their ipad2.
We both have the latest operating system updates.
