To use the functionalities of OCS you will need a client, either a hardware device or software installed in your computerphone.

Communicator Web Access, also called CWA makes it possible to deliver OCS access via a Web application. This has an advantage that not each client has to install the client on hisher computer. Server roles. As with Exchange, OCS has also several roles to deliver services to end users, in the following chapters I will give a short overview of the server roles and what the functionality of each role is Front End server. An OCS environment can have one or more Front End servers. These servers are responsible for delivering instant messaging, presence and enterprise voice to the end user. All OCS enabled users will be placed on a Front End server. There is one exception for this, when using the Front End server as a director it will only do user authentication and therefor will not have any user hosted on it. With the director you can create an extra layer of security by letting only the Edge Server communicate with the Director. The director will then contact the Front End servers where the user is hosted. Delivering OCS services is done by publishing servicesapplications. The pool can publish the following servicesapplications Front End, provides login functionality, IM and voice capabilities to users and ensures that calls are routed to the Exchange 2. Unified Messaging Server Role when configured. IM Conferencing, provides server managed group IM, this is used if you add multiple people to one instant messaging chat.
