The Channel Availability feature is designed to allow agents to focus on either inbound or outbound interactions.
When clicking on the Channel Availability icon you will have an option of inbound or outbound to select.
Selecting Inbound will enable the agent to only receive inbound phone calls and when selecting Outbound, the agent will only receive campaign leads.
Please note that if there is no campaign environment, the Inbound channel has to be selected to receive inbound calls.
