Cisco provides a set of sizing tables in the Cisco Unified Contact Center Enterprise 8.0(x) Design
Guide (SRND). These tables show the private network bandwidth that is required for the clustering
over the WAN deployment model. Using these tables, how much bandwidth is required to support
the following configuration:
BHCA coming into the contact center is 10,000.
One hundred percent of calls are treated by the Cisco Unified IP IVR, and 40 percent are queued.
All calls are sent to agents unless they are abandoned; 10 percent of calls to agents are transfers
or conferences.
Four Cisco Unified IP IVRs are used to treat and queue the calls, with one Peripheral Gateway
pair supporting them.
There is one Cisco Unified Communications Manager Peripheral Gateway pair for a total of 900
agents.
Calls have ten 40-byte call variables and ten 40-byte ECC variables.
