A conversation participant with hidden roster visibility is a trusted application that performs specific conference services. An example is a trusted application which announces conference roster events to participants who join the conference through audio only. A client application such as Microsoft Lync 2010 will not display such applications in the roster UI.

Conference participants can be users or trusted applications that perform specific conferencing services. Applications will still receive notification events for hidden participants, however, most applications with a user interface (UI) are expected to check for hidden participants and not show them in the UI.
