In this how-to, we will be installing a Mumble VoIP server on Ubuntu 15.04. Mumble is an open source, low-latency, high-quality voice chat software primarily intended for use while gaming.


To install Mumble, you will need an Ubuntu 15.04 server, if you do not have a server, consider spinning up a Cloud Server from Atlantic.Net in under 30 seconds.

Install Mumble

Mumble may not be available in the default Ubuntu repository. To add the repository–

sudo add-apt-repository ppa:mumble/release

An example of adding the repository in Ubuntu

or if that command does not work, you may do the following. —


An example of the install process

sudo dpkg-reconfigure mumble-server

Advanced Config

To configure, open up /etc/mumble-server.ini via nano or vi (user preference):

nano /etc/mumble-server.ini

In order to avoid users from affecting your Mumble server negatively , you may use Mumble’s global-ban system.

The below configuration is set so that if someone attempts to connect to the server (unsuccessfully) 5 times within 60 seconds, they will be banned for 150 seconds.

autobanAttempts, autobanTimeframe and autobanTime
#autobanAttempts = 5
#autobanTimeframe = 60
#autobanTime = 150

In order for these rules to take place, you must remove the # in front of each line.


You will be able to choose a password for your server here. Be sure to use a strong password such as: f;Q=uS6/#BK5t<(9

# Password to join server.


This setting displays a message to the users every time they login to the server.

# Welcome message sent to clients when they connect.
Thank you for choosing! We hope you enjoy your stay


The default port used by mumble if port 64738.



With this setting, you can limit the number of users allowed on the server at one time.



Set Allowhtml to true to allow HTML to be used in messages.


Press Ctrl+X to exit /etc/mumble-server.ini

Perfect, now your Mumble server is installed and configured!
