Openfire Meetings is a real-time communication server implementing the XMPP (Jabber) and WebRTC protocols with a SIP gateway. It offers a very large number of features and a great admin panel and source code is available under the Apache 2.0 license. It includes Jitsi Meet and Converse, and interacts with Pàdé. The Openfire Fastpath Plugin adds support for managed queued chat requests, such as a support team might use. For example, a web based "Live Support" interface can point a potential customer at a workgroup representing the Sales team. Members of that workgroup will receive notification that a someone is waiting and when someone from that workgroup accepts, the customer and the team member will be connected to communicate with each other.

"Although jitmeet Jitsi Meet and ofmeet (Openfire Meetings) look similar, they are different underneath and are heading in different directions. Jitsi Meet is for generic XMPP servers and aimed at public internet facing conferencing using services like prezi.org and etherpad.org while Openfire Meetings is for private in-house conferencing where all collaboration applications are integrated into Openfire. For example, Ofmeet uses a PDF viewer which supports in-house corporate powerpoint presentations, while Jitmeet uses prezi.org."
