According to a Microsoft case study:
The University of Kentucky (UK) IT organization selected Microsoft Office Communications Server (OCS) 2007 to manage its large telephony infrastructure, then discovered that unified communications (UC) can also reduce costs and enhance communications. Although specific to UK, this Case Study provides a useful model for how other organizations can develop a practical UC strategy.
Key Findings
- Implementation of a UC strategy provides a foundation for efficiently growing, enhancing and managing all aspects of an enterprise communications infrastructure.
- The uniformity provided by OCS 2007 enabled the university to control and reduce communications costs, while improving personal productivity and fostering collaboration. An implementation doesn't necessitate the integration of OCS 2007 voice communications for all users, which diminishes the need to totally upgrade the time division multiplexing (TDM) platform.
- OCS 2007 audioconferencing costs significantly less than conferencing provided by service providers. When deployed with Exchange Server 2007, Microsoft's unified messaging (UM) solution was a cost-effective voice mail solution for the university.
