I have got attendant console configured at one of our sites and it is working fine except that the receptionist has no way of knowing if the staff member's extension is busy or not. This is important during call transfers etc. I can only see a ? on the line status column in the Directories box. In a nutshell I am looking for a BLF type of functionality that has been available lately in UCM 6.x. Our CM at the moment is CM 4.2.1 and I am assuming that this is not possible with 4.2.1?
