There's a new PR mumble with loads of new features, as quoted:

"After joining the PR Mumble server, that's about it! You don't have to do anything else. You don't have to know what channel to join, which team is which, etc. You get automatically moved to the right channel when you join a server in-game. If you disconnect from the in-game server, you get moved out of the channel and won't bother anybody playing. Awesome.


There's a new structure in place, where each squad has their own sub-channel.

Again, you don't need to manually change channels when joining a squad in-game, our server does that automatically for you. You will always be in the right place to talk to the right people.

This allows for a more complete set of communication lines between the team (the default shortcuts can be changed in the settings):
Local Speech (default H): you talk to players in the 3D world in a radius around you.
Squad Radio (default NUM 0): you talk to your squad, no matter where they are, like BF2 voip B.
Squad Leader to all Squad Leaders Radio (default NUM *): you talk to all Squad Leaders in the team.
Squad Leader to specific Squad Leader Radio (default NUM 1-9): you talk to a specific Squad Leader in the team.
Squad Leader to Commander Radio (default NUM /): you talk to only the Commander, like BF2 voip V.
Commander to all or specific Squad Leaders Radio: same as described above, but starting with the Commander.

You could communicate specifically to the CAS squad or to the transport squad, without spamming the Squad Leader radio with information that other people don't need. If used properly, this can be amazing for keeping comms clear and useful."
