Agents are using Thin Clients. Thin clients are dumb computers. When agent presses the power button on thin Client, a virtual desktop is launched. Using that they open One X application
This one X application is not installed on thin Clients, rather it is installed on a server
Agents when try to change states, One X freezes. Agents receive inbound calls when they are not suppose to and sometime they do not receive calls when they should.
In a nutshell, the actual state of OneX is not received by CM and so the call is send to the agents, when agent are in break state or vice versa
