Collaboration Sizing, Configuration and Quoting Tools
The Cisco Unified Communications (UC) Sizing, Configuration and Quoting Tools assists you with hardware sizing for large or complex Cisco Unified Communications solutions. The tools calculate the call-processing requirements for products that have a major impact on performance and scalability.
System engineers or individuals with equivalent Cisco Unified Communications solution experience can use the sizing tools to design and model solutions for existing and prospective customers. The tool requires various types of information to calculate the minimum size and type of devices required for a solution, such as the type and quantity of IP phones, gateways, and media resources. For most device types, the tool also requires the average number of call attempts per hour per device during the busy hour (busy hour call average, or BHCA) and the average usage time. The tool generates calculations that you can copy, save, and send to other users.
Cisco makes assumptions about end-users’ requirements for the purpose of describing Unified Communications (UC) deployment examples in this guide. These assumptions may not align to your specific deployment requirements; use these sizing tools to calculate accurate hardware sizing and VM count.
