XEP

XMPP Extension Protocol (XEP) is a component within the XMPP designed to expand upon the functionalities defined in XMPP's core RFCs. They serve as standardized extensions that enable XMPP clients and servers to support a wide range of additional features and capabilities.

3. XEP-0166 (Jingle): voice calls and video conferences.
