Feature Interactions
Extension Status
A CMS supervisor uses the Extension Status feature to control and
monitor when agents are in the available, unavailable, or ACW state. A
CMS agent does not have to be a member of a calling group to be
available or unavailable. The system can be programmed for CMS or for
Hotel/Motel Extension Status, but not for both.
Group Calling
CMS agents log in and out by using the same buttons or codes as
calling group members.
