Overview & Setup:

To setup voicemaster, you need to run the following command:

;voicemaster setup

This will create an interface channel and a voice channel used to create a channel for the user.

These two channels are needed for the voicemaster module to work. Joining the join to create voice channel will create a voice channel in which that user owns and can control.
