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.
