Since we are already using the Zoom videoconference service in production at CERN, we released the current version of the Zoom plugin for Indico as a beta version to the general public as well.
You can find more information on the plugin in its README file (including a changelog since the last beta); and if you would like to give it a try, simply
pip install indico-plugin-vc-zoom, enable the
vc_zoom plugin in
indico.conf and configure it in the Indico admin area.
