Zello allows prompt voice push-to-talk group communications worldwide. The push-to-talk audio is shared simultaneously in a “channel” using internet-connected phones, tablets, computers and Zello WiFi walkie-talkies. For those accessing Zello from a computer, the Zello Windows program works from Linux using WINE.

Note that Zello requires an internet connection to work. If your device loses its data connection, Zello does not work.

Install Zello on Linux

Download Zello for Windows PC. Install Zello with WINE

wine ZelloSetup.exe

This creates a Zello icon to launch the Zello app in Linux.

Optional: command-line Zello

Make a script “zello.sh” like the following, that can be conveniently run:

#!/bin/sh

wine "$HOME/.wine/drive_c/Program Files (x86)/Zello/Zello.exe"
