What was the last successful French software project in the Telecom or Conferencing space?

This project has been forced into the hands of 40k users, but likely due to a plethora of bugs and user experience issues they are picking a date far in the future for broad deployment.

Belledonne Communications has been actively breaking Linphone, conference calling broke back in August 2023 for example and remains broken to this day.

If we look to Québécoise in Canada, SFLPhone would crash after 2 dozen calls, and Jami (formerly GNU Ring) is still a beta quality product with some neat DHT concepts that I'd love to see work.

The French sphere has a software delivery and quality problem. The user rejection factor will remain high until they choose to fix the bugs that cause users to run away.

Ffmpeg.

Basically all videoconferencing (except teams) is built on the back of French open source software.

Idk, VLC is kinda everywhere and while not the super cutting edge of video playing anymore, is still pretty OK. If they'd just attach a chat and SIP client to VLC they'd be set.

Impossible n'est pas français !

And you seriously are saying Teams is the greatest thing since sliced bread? Ok I concede the videoconferencing works, but it's quite a feat to make a text chat window so slow and buggy. Sometimes when I type, it is spelling stuff backwards! Message texting is a solved problem since IRC or ICQ

CYCLADES (https://en.wikipedia.org/wiki/CYCLADES) was influential in the design of important Internet concepts like the OSI model and TCP.
