Openfire (formerly Wildfire) is a real-time collaboration (RTC) server dual-licensed under the Open Source GPL and commercially. It supports instant messaging, group chat, and VoIP and uses the only widely adopted open protocol for RTC, XMPP (also called Jabber). Openfire is incredibly easy to setup and administer, but offers rock-solid security and performance.

Use Openfire in your organization as a more secure and feature-rich alternative to the consumer IM networks. Or, replace your existing EIM server with a more open, easier to use, and much less expensive solution.
