Implementing and Maintaining Telephony by Using Office Communications Server 2007

Course OutlineModule 1:
Implementing and Maintaining Telephony by Using Office Communications Server 2007

Office Communications Server 2007 supports both PBX telecommunications and SIP telecommunications. To capitalize on the SIP telecommunications functionalities, enterprises can integrate Office Communications Server 2007 into their telephony solution. This module describes the basic components of an enterprise telephony solution, such as PSTN, PBX, SIP-PSTN gateways, and endpoints, and security considerations for implementing a secure telephony solution. The module describes the Active Directory design considerations and networking considerations for deploying Office Communications Server 2007. The module also identifies the installation considerations for distributing the Office Communicator 2007 client to enterprise users. Finally, this module introduces the administrative tools that Office Communications Server 2007 provides to manage and monitor the enterprise telephony solution.
