I am using Zoiper with Fusion Talk and when I call a Japan phone, I hear them fine, but they cannot hear me.
I also notice that the phone defaults to speaker phone and doesn't allow me to disable the speaker phone function.
the same problem iPhone 5
I have the same issue. I can hear the called party but they cannot hear me.
