In order to properly determine how many Cisco Voice Gateways are needed in a Cisco Unified Customer Voice Portal deployment, the following information is provided by the customer:
“We typically receive about 6000 calls a day, higher on Mondays. Each call lasts an average of four minutes once the caller is talking to an agent, and the average queue time is about five minutes. Also, there is about a one-minute prompt and collect activity when the call first arrives. All calls go to a single contact center, and the data center is located on-site. All the contact center agents are on Cisco Unified Communications Manager IP phones with Cisco Unified Contact Center Enterprise Cisco Agent Desktop.”
