In addition to the code you have recieved, you could also type the following command to auto voice any user that joins your channel: /avoice * #yourchannel in the correct server window where you want it to work. If you want to make it work on all servers, you can type: /avoice -w * #yourchannel
If at some point in the future, you want to disable this functionality you can specify this command: /avoice -r * #yourchannel if you had specified it first without the -w flag, and /avoice -wr * #yourchannel if you specified it with the w flag.
