Zello can utilize one of the buttons on the Voyager to trigger PTT, when Zello is in the foreground or background. The back button works as PTT, and the button underneath the microphone replays the last message when pushed quickly.
The button works as toggle mode only but requires no special set-up. Simply, pair with your Android device and make sure that Bluetooth is selected in the bottom corner in your talk screen.
Simply, press to start talking, and then press again to stop talking.
