Currently we use Slack for company meetings and one-on-ones. It works very well, but it's a bit flaky at times. Our other solution, which we still use with customers and other external parties, is GoToMeeting (Citrix). It's about $180/year, I think. The app, despite being native, looks like something from 1995, and there's very little mobile app functionality to speak of, and also screen sharing is broadcast only, and it has some minor idiosyncrasies (for example, new people who join are muted initially, and the app's UI makes it ridiculously difficult to figure out how to unmute (hint: it's not the microphone icon next to your name)), but it does have several advantages: * Audio and video is just rock solid. Unlike Google Hangouts, Slack and other web-based solutions, GoToMeeting just works. I can count the number of times we've had people struggle with audio/video on one hand. I don't know what the others are doing wrong (WebRTC?). * You can dial in with a normal phone. This is useful when you have people who don't have/want the app, or if your Internet connection is slow or flaky. * You can join a call very quickly even if you don't have the app. The invitation contains a link to an app download that, when opened, immediately joins the right call. * You can record calls (including screen sharing).
