Hi

I understand that with Lync 2013 (server/client) comes the ability to have persistent chat. I'm trying to understand what this is really.

Is the same the same functionality as a chatroom where messages are displayed indefinitely (i.e. don't need at least one party to remain active, and also a client can jump in and out and see the history).

Had some questions:

1. Does there need to be more than 2 parties for persistent chat to work (i.e. does it require multi-party, not just 1 to 1)

2. Can persistent chat be enabled for just 1 to 1 messaging

3. Is this dependent on the client (i.e. will this work with Lync 2010 client or mobile clients)

4. Do all parties require the same client

How Persistent Chat Works

One of the key architectural points to keep in mind with Lync Server 2013 Persistent Chat is how requests are routed to the Persistent Chat servers. Persistent Chat services run on a dedicated pool. The Persistent Chat pool depends on the Lync Server pool to route messages to the Lync clients participating in a discussion. Lync clients communicate with the Persistent Chat services by using Extensible Chat Communication Over SIP (XCCOS).

The following steps outline at a high level the client sign-in process to Persistent Chat:

The Lync 2013 client retrieves basic permissions from Lync Server 2013 via in-band provisioning.
Lync Server 2013 responds to the Lync client if the user has the ability to sign in to the Persistent Chat pool.
The Lync 2013 client contacts the Persistent Chat server.
The Persistent Chat server responds with the rooms the user has been granted rights to participate in.
The Lync 2013 client retrieves the list of accessible rooms.
The Lync 2013 client sends message invites to any new room the user wishes to participate in.

1. Two parties are enough

2) Yes, the chatroom manager will have permission to have one to one

3) Yes it works well with Lync 2013 basic client not sure about Lync 2010 or older version, if you have in real-time you can test on your environment. Both Lync 2010 and Lync 2013 are almost similar.

4) Not sure but if you have mixed clients you can test it
