Integrating Telephony with Office Communications Server 2007 white paper

ABSTRACT

This paper defines in detail Microsoft’s strategy and approach to an enterprise’s integration of its telephony systems with Office Communications Server 2007.

In order to address the needs of our diverse customer base, we have defined several deployment scenarios and each is described in detail, including high-level feature descriptions, migration paths and call flows. A broad ecosystem of partnerships has been created to facilitate the deployment scenarios and to smooth the path to deployment and integration. Programs to support these partnerships have been implemented and these are also described.
