An unexpected tool has helped tremendously for our teams in terms of remote work: Mumble (<a href="http://wiki.mumble.info/wiki/Main_Page" rel="nofollow">http://wiki.mumble.info/wiki/Main_Page</a>).<p>Mumble is a cross platform, open source VoIP application. Often used for gaming in a group (like Teamspeak or Ventrilo). It has the idea of channels (rooms, offices, etc) is very high quality, low latency and low bandwidth installed on your companies servers in minutes, always encrypted... and clients are available for linux, windows, os-x, android, ios, etc.<p>So you can have channels like "Bob's Office", "Working on XYZ problem", etc. People can come into these channels to speak to you and can leave them. It feels a bit like an office environment, I can pop into Jay's office, talk to him about an issue, and go back to my office. I recommend people setup Push To Talk, which really helps create a silent non-annoying environment. Basically, me and another developer can be working on an issue, but maybe not actively talking, but in the same channel -- and there is blissful silence... I don't hear the fan, the cat, the fact that his wife came into talk to him for a minute, etc.<p>When I start my work-day -- I start it by logging into the mumble server (or more accurately, moving myself out the AFK channel) -- and when I end it, I move myself back into the AFK channel. This is a realtime communication system, async work still happens... well, everywhere else.<p>It is easy to be on all day as an "in-office" experience... when I am eating lunch, I create a "eating lunch" channel under AFK and put myself there.... We find it works so much better than video chat (or really anything else), is far more casual (like an office) and far more fluid... it is like having an open door policy. Sometimes I might be in a channel that says "Debugging Race Issue Go Away" -- but it technically doesn't keep anyone out, it is a request.<p>Using mumble day to day basically changed the experience from mediocre to great for us. We still use everything else, but mumble is our real time core, and slack is our async core.
