I have at least 3 or 4 agents out of 150+ call center that constantly go into a Ready not Ready Agent State. What could be causing the issue?
I know it's not the agents themselves going off hook because I've sat next to them when it happens.
Since its happening to only 4-5 agents, server issues can be ruled out. Try finding out if this is a desk specific issue or pertaining to agent. Let these agents login to some other PC's and make a check.
A network connectivity check to IP Phone and desktop would be worth to start with.
(Pls rate if this helps.)
If you are using UCCE then must check the device targets of these IP phones if it is happening on receiving call. Also check out the remarks of "lpezj" if using UCCX,
