I used Linphone via Flatpak on Debian 9 and it works great. I did not try yet the video, but the SIP works great (sounds quality is very good), and it's easy to use, and OPEN SOURCE !

Sadly it can't be installed through their Flatpak anymore, it's been broken for at least 3 months: https://gitlab.linphone.org/BC/public/linphone-desktop/issues/10
Ubuntu 19 only has an old v3 version in its repo, like most distros.
