As in previous years, we were at FOSDEM 2026 as both exhibitors and speakers.
Alexandre Jorgensen and @jehan_monnier@mastodon.social gave a talk in the “Collaboration and Content Management” room, focusing on the integration of telephony within a Digital Workplace. You can watch the replay here: https://fosdem.org/2026/schedule/event/TW7QMN-open-source-telephony-digital-workplace/
At our booth, we met many open-source enthusiasts interested in VoIP.
Many thanks to the FOSDEM team for the excellent organization. See you next year!
