Avaya Call Management System (CMS) is a part of the Avaya Contact Center – Extended Capacity solution that collects call traffic data and formats management reports. Without the CMS connection, you cannot get call traffic reports and monitor agent performance. CMS is connected to the CMSi service that runs on the Routing Core Server.
