Currently evaluating different remote collaboration software platforms. We use microsoft teams for a subset of the platforms, but need to ability to receive phone calls from customers.
Skype has not really let me down, ever.
At a previous job I had good experiences with Bluejeans as well and it never gave us trouble. Best A/V quality as well.
GoToMeeting/Zoom/TeamViewer has always been part of the sales/support team arsenals, so they’re still using those as well.
On the personal front, I chat with some friends via Slack, and then we play games in the evening on PS4 (does Apex Legends count as personal collaboration?).
In Toastmasters we mostly use Zoom. The disadvantage is that it is not free (if you need more than one to one and more than 40 minutes) and that you can't have a standing meeting, somebody needs to host it and when the host leaves, the meeting is over. Upside is that it works, and that you can have basic things like push to speak, mute all participants, etc.
If somebody is looking for a start-up idea, a zero setup, click here to generate an url and send it to others to have a video meeting would be a god-send. Slack gets it right by continuing the call as long as at least one person is still connected, even if the person who started the call has left.
Websites, like github or jira, are also OK.
