I have a BCM450, R1 with CC. What they want is to be able to silent monitor Contact Center calls. When I log in and do a F905, and enter the agent ID, I hit the OBSV soft key and all I see is either "busy" or "idle" and how long they have been in that state. How do I listen to the calls? F*550 doesn't work because these phones are not in a hunt group, but in a skillset.
