Skype Replacement for Small Business?

cross-posted from: https://programming.dev/post/26910708

My small company (less than 30 employees) has been using Skype for internal group meetings and messaging. Since it's closing, we're looking for alternatives.

I think few people in the company are privacy minded (one of the higher ups had to get scolded to stop using some random AI to listen to all his meetings and write summaries), so we need something with a low barrier to entry.

We have basically no IT department, so self hosting would be a challenge. We do self host a redmine server via docker, and we have to connect to it via VPN when we're off-site (we have several full time remote employees).

Our feature requirements are: Group and individual messaging Screen sharing Meetings up to 2 hours Inexpensive Meetings with up to 10 participants Windows (some people use Skype from their phones also, but not a requirement) Minimal friction to setup and use Minimal bugs (mature)

Some of the ideas floated: Teams Discord Google Meet Signal Telegram Jami

I really don't think we could pull off Matrix, but am I wrong? Which of these ideas bothers you the least? Is there something else I'm overlooking?
