Can anyone tell me why we have a 5 digit number in the DN field of the IVR Detailed Call by Call report? What does this number represent?

I have agents who login to take calls remotely. We can see them for a brief second when they login and then they disappear from the Supervisor desktop. HHowever, they are taking calls.  What is causing this issue? Why can't I see them?

Any recommendations for a Wall Board for UCCX 7.0?

Is a readerboard required in order for CAD agents to see calls in queue?
