The limit of concurrent agents per application server is 600 the limit of concurrent agents per
application server according to Cisco Unified Contact Center Enterprise (UCCE) version 11.5 and for
the hardware specification that meet the requirement. This recommended limit is based on the
assumption that all agents are using IP phones or soft clients and that the agents are using average
resources. However, It's important to keep in mind that this is just a recommended limit and it may
vary depending on the specific version of UCCE and the hardware specifications of the application
server.
