FFXI Or Server Specific Private Mumble Servers?

I was wondering if there are any FFXI, FFXIAH, or FFXI(servername) private mumble servers out there. Skype quality sucks so my girlfriend and I use mumble while I walk her through missions and stuff, but the griefers on the public servers are relentless idiots. I saw you can get a free guild mumble server through guildwork but have no idea if its true or how to set it up.

I've heard good things about Discord, which Stan from Guildwork is part of.

I saw that while trying to find out how to get the guildwork mumble server so I guess I'll check it out now. Getting tired of the wannabe trolls shitting all over our conversations.

Just tried it out and it works pretty well! I haven't even had to adjust any voice settings yet on mine or girlfriend's laptop. She was talking using the built in microphone and speakers and I didn't even hear an echo! Looking forward to trying it for an extended time tomorrow.
