[App_rpt-users] Zoiper not Transmitting

Hi all, I installed Zoiper on my Android phone and configured my node. When I connect using Zoiper, I can hear fine on the phone, but the “mute” button won’t allow me to transmit from the phone. I than installed Android IAXRPT on the same phone and it transmits and receives fine using the same setting that I used in Zoiper. As a final test, I installed Zoiper on another Android phone and had the same issue, mute button won’t allow me to transmit. Any idea’s? Thanks, Steve_WB8GRS
