OK, the secret is out of the bag. I'm creating a new Open Source VoIP system, called QuadPBX - https://quadpbx.com/ - because I'm a bit miffed with what has happened to my PREVIOUS Open Source VoIP system (the one with the frog, you know).
There's also a Discord instance, but I feel that we probably should use something else. Suggestions welcome.
So, if you like #opensource and #voip and those sort of things, please boost this post so other people learn about it - and feel free to suggest things!
