I can't really see a business case where an operator needs to monitor a large number of extensions : if a switch attendant has a lot of extensions to manage, (s)he won't spend a lot of time on each incoming call.<br>
Chances are (s)he will just transfer incoming calls to destinees leaving screening or queues features forward those calls to secretaries if bosses can't be disturbed.<br><br>IMHO, those secretaries are the end users of FOP, not switch attendants.<br>
And FOP is perfect for secretaries ...<br>
