The word from Cisco: the product (Attendant Console Standard) is working as designed. The idea is quickly to make the operator aware of a new incoming call.
The customer has Attendant Console Standard, which doesn't seem to have the same options as Advanced.
I have opened a TAC case, and I'll report back the findings into this thread.
I'm concerned the prior message on this topic was two years ago, and there's not been a response. I too have this issue, and the customer assures me this is not what they want.
