@Junior sorry your connection was a dud to mumble. Let me know if you want help debugging it before another call.
Re: mumble versus video. 2 years ago we tried all the tools for calls, and wasted a lot of time with unreliability - connections breaking, audio chopping. like 10-30 mins every call. Then @cel set up the mumble server, and it just fucking works (at least 99%). You can't imagine how much of a relief this was (for me).
