Presence Services supports multi-user chat with federated users and Avaya Workplace Client clients. Presence Services supports multi-user chat sessions for XMPP and Microsoft RTC federated systems.
Either Presence Services or the remotely federated system hosts the multi-user chat rooms or multi-user conferences. This is determined by which client, local or federated, starts the chat session.
The following are the general limitations for multi-user chat support for both Microsoft RTC and XMPP federation:
Presence Services does not support multi-user chat with a federated XMPP contact and a federated Microsoft contact in the same chat session.
Avaya one-X® Communicator supports XEP0033 extended addressing for multi-user instant messaging. But it does not support XEP0045 multi-user chat. Therefore, Avaya one-X® Communicator does not support XEP0045 multi-user chat sessions with either Avaya Workplace Client or any federated contacts. Presence Services supports XEP0045 multi-user chat sessions only with Avaya Workplace Client clients.
The following are the XMPP specific limitations for multi-user chat support:
Presence Services does not support multi-user chat rooms with passwords hosted on Presence Services or on a federated system.
Presence Services does not support anonymous multi-user chat rooms.
Avaya Workplace Client does not support modification of multi-user chat room nicknames. Presence Services pre-configures an Avaya Workplace Client user nickname to be the user’s Presence/IM handle, including the domain.
Presence Services does not allow modification of participant nicknames of a multi-user chat room that is hosted on Presence Services.
