This Mumble Moderator modules can limit the user count of a channel. This functionality is already included in the official Mumble server but server wide only. usersperchannel. With this module one can set different limits per channel.

If a user enters a „full“ channel he will immediately be moved back to his previous channel.

Get the module from GitHub, see http://github.com/ExplodingFist/mumo-maxusers/ and read Installation of Modules for Mumble Moderator.

Or use my fork at https://github.com/Natenom/mumo-maxusers which moves users into the default channel or root channel if a channel was removed while the user was in the AFK channel through the DeafToAFK – Module for MuMo.

• Set a limit per channel or per server.
• Define a group whose members are not affected by a limitation.
• Define a channel where users will be moved into if their previous channel does not exist any more.

• Channel for private talks
• Gaming channel without listeners

An example configuration can be found here.

On our server we use the following configuration:

[maxusers]
servers = 
limit = 0
ret = 15
exceptions = admin

;Zweiergespraech
[channel_2956]
limit = 2
exceptions = moderator

;Gruppentreffen
[channel_2956]
