Redundant Unified ICM Distributors and AW Servers
Administrative Workstation Real-Time Distributors are clients of the Unified ICM Call Router real-time 
feed that provides real-time information about the entire Unified CCE across the enterprise. Real-Time 
Distributors at the same site can be set up as part of an Admin Site that includes a designated primary 
real-time distributor and one or more secondary real-time distributors. Another option is to add Client 
Admin Workstations which do not have their own local SQL databases and are homed to a Real-Time 
Distributor locally for their SQL database and real-time feed.
The Admin Site reduces the number of real-time feed clients the Unified ICM Call Router has to service 
at a particular site. For remote sites, this is important because it can reduce the required bandwidth to 
support remote Admin Workstations across a WAN connection.
When using an Admin Site, the primary real-time distributor is the one that will register with the Unified 
ICM Call Router for the real-time feed, and the other real-time distributors within that Admin Site 
register with the primary real-time distributor for the real-time feed. If the primary real-time distributor 
is down or does not accept the registration from the secondary real-time distributors, they will register
