LUCS allows extending the functionality of the Lync\S4B conversation window by creating a conversation context. Conversation context is a Silverlight add-in that allows users to get additional context while having a conversation.

Your defined conversation Context is selectable within within your Service Call Context tab when configuring your services.

You can add new context by clicking ‘+Add‘ or edit any existing entry in the list.

The ‘Conversation Context’ page is accessible on Settings -> Service -> Conversation Context:
