Avaya Call Management System (CMS) is a software product for businesses and organizations that receive a large volume of telephone calls processed through the Automatic Call Distribution (ACD) feature of the Avaya Aura® Communication Manager system.

CMS runs on the Red Hat Enterprise Linux (RHEL) operating system and uses various operating system utilities to communicate with terminals and printers, log errors, and run processes. The Informix database management system provides an interface to the CMS historical database.

As as administrator or supervisor, you can use CMS Supervisor to access the CMS database, generate reports, administer ACD parameters, and monitor call activities to determine the most efficient service for customers calling the contact center. The Tenancy feature enables you to restrict user access to CMS reporting data and functionality within the call center.
