Overview
The maximum supported capacities / sizing for Cisco Expressway Series (not Cisco VCS) are listed in the tables below. These figures are guidelines only and are NOT guaranteed, because many factors affect performance in reallife deployments. Expressway supports so many different use cases that it is not possible to provide capacity limits for individual, specific deployments.
Expressway sizing / capacity information is categorized on the basis of the number of supported concurrent registrations and/or calls.
