Jitsi Meet is an open-source voice and video-conferencing application that can run on any smartphone or within a web browser. Jitsi is an excellent alternative to proprietary videoconferencing applications (Zoom, Skype, Microsoft Teams, Google Hangouts) and is open for anyone to use either as a host of a meeting or as an attendee.
Simply download the Jitsi Meet app to your phone from your preferred app store, or visit the Jitsi website to use the meeting software within a web browser. Users also have the option to run Jitsi on their computer by downloading the desktop version.
Above Privacy Suite (APS) customers using Jitsi Meet have all of the Jitsi Meet features, and also enjoy the added benefit of having their meeting instance hosted on Above's private Jitsi server. As a paid service, customer's using Above's private Jitsi server can rest assured that their meeting is truly private as Above does not log data either from the content of your meeting or any information about the participants involved.

Secure, end-to-end encrypted meetings riding on open-source software and hosted on a private server that does not retain or sell any information - the gold standard in private, secure communications.
