What GOnnect is
GOnnect is a free, GPLv2 open-source desktop client for phone calls, chat, and video conferencing. It operates as a SIP client with call transfers and ad-hoc conferences, and lists Asterisk, Fritzbox, and Cisco as compatible systems. During an active phone call, users can switch to a Jitsi Meet video conference with one click. The client includes busy lights, configurable audio, automatic media control for incoming calls, system-tray access, auto-start, global shortcuts, and design customization. GOnnect is intended for companies and organisations, including professional enterprise use, while self-managed operation keeps sensitive data under the user's control. The current Linux version is distributed as a Flatpak; Windows remains in active development. The changelog identifies version 2.4.1, dated July 31, 2026, as the latest release, and lists Microsoft calendar and contact plugins plus CardDAV support. Matrix integration is planned. GOnnect has no browser calling, mobile app, or call recording.
