I set up a 24/7 teamspeak server for my society a few weeks ago. It’s free to join for everyone who wants to but has a few channels that are for society members only. It’s extremely handy when we go out grouphunting or are attending events andeven just for some general chat 
I hooked it up to our website so it’s easy to connect to and you can also see the stats etc. One click launches your TS client and lets you join the channel you clicked
I use TeamSpeak.
Really good in hunt.
