I am running UCCX - 7.0(1)SR03_Build011
agents sometimes get this msg.
"the agent extension is out of service. Ready state change and call control operations cannot be performed".
I do see other netpro discussion where ppl restarted the CTI manager on CUCm to fix issue.
I can probably do the same thing to fix it. But I would like to know why it happens. Whats the root cause.
