ATTENTION

Customers must not use their Office Communicator client to call Emergency numbers (for example, 911). To ensure that emergency service organizations can accurately trace the source of the call, always use a desktop phone to place

an emergency call.

Hardware Load Balancer

Hardware IP Load Balancers (for example, Nortel Application Switches) are required for multiple Office Communications Server 2007 Enterprise Edition deployment. The Load Balancer presents a single virtual IP (VIP) address to clients to prevent direct access to individual OCS 2007 Enterprise Edition servers. The Load Balancer uses an algorithm (for example, round-robin, or fewest connections) to route new client requests to the Office Communications Servers.
