Automatic Call Distribution (ACD)
ACD enables the use of phones in a call-center role by automatically distributing incoming calls to available users
or agents. You can enable users to use their phone in a call center agent/a supervisor role on a supported call
server.
The users can sign in and sign out of the ACD state as call center agent using soft keys. The server distributes calls
to the agent when the agent state is available, and stops distributing calls when the agent changes state to unavail-
able. The IP phone remains in the unavailable status until the agent manually changes the IP phone status. You
can configure how long the IP phone remains unavailable state and changes to available automatically on a sup-
ported call server.
