Each time you accept a conversation from the queue, the USD creates a new session. USD sessions make it easy to handle more than one conversation at a time while keeping everything in context. Sessions appear in the main panel of USD as separate tabs.
When you are engaged with one visitor, and accept another conversation, two things will happen.
1. An additional avatar circle will appear on the right side of the Agent Widget.
2. An additional session will appear in the USD as a new tab.
Switching between conversations is easy. Simply click on the other avatar circle in the Agent Widget. Or, click on the other session tab in the main panel. Both actions have the same effect. The other conversation will open in the Agent Widget and the other USD session will open in the main panel.
