What is the maximum number of concurrent agent web chat sessions that are supported on...

The maximum number of concurrent agent web chat sessions that are supported on the highest class server is 50. This means that each agent can handle up to 50 simultaneous web chat contacts on a server that meets the highest specifications for Cisco Unified Contact Center Express (UCCX). The highest class server for UCCX is the Cisco Unified Computing System (UCS) C240 M5, which supports up to 400 agents and 400 IVR ports1.

The other options are not correct because:

A. 75 is not the maximum number of concurrent agent web chat sessions that are supported on the highest class server. 75 is the maximum number of concurrent agent web chat sessions that are supported on the second highest class server, which is the Cisco UCS C220 M5. This server supports up to 300 agents and 300 IVR ports1.

B. 25 is not the maximum number of concurrent agent web chat sessions that are supported on the highest class server. 25 is the maximum number of concurrent agent web chat sessions that are supported on the third highest class server, which is the Cisco UCS C220 M4. This server supports up to 200 agents and 200 IVR ports1.

D. 120 is not the maximum number of concurrent agent web chat sessions that are supported on the highest class server. 120 is the maximum number of concurrent agent web chat sessions that are supported on the entire UCCX system, regardless of the server class. This means that the total number of web chat contacts across all agents cannot exceed 1202.
