Even for quick conversations, video chat is much better than a phone call because it has higher quality audio and you can see the visual cues of when it's your turn to talk.

There are plenty of easy browser-based video chat applications using WebRTC like https://appear.in/. You can send people URLs to your video room and there's no software to install.

I have pretty much moved over to appear.in 100% now, I find its latency is much better when working with remote teams (I am based in Australia and the stakeholders are in the USA (East and West coast) - Appear in is flawless, have had 8 people on a call and it just works, hangouts frequently craps out unless bandwidth is perfect!
