The Total Cost of Ownership Benchmarking Study for Unified Communications
Throughout 2011, Aberdeen analyzed the Total Cost of Ownership (TCO) associated with IP and legacy TDM (Time Division Multiplexing) telephony systems in 236 different corporate environments on a worldwide basis. TCO Categories measured include capital costs, implementation and training, ongoing support, system administration, and network/long distance usage. This study provides specific insight for TCO in eight comparative metrics associated with the following telephony solutions: Cisco Unified Communications Manager (UCM), Cisco UCM Express, Microsoft Office Communications Server (OCS)/Lync, Avaya Aura Communication Manager, Avaya IP Office, ShoeTel and various legacy TDM systems.
