In CCM you can use shared lines, for example assistant 1 with extension 1001 has two Managers (extensions 1002, 1003). On Assistant phone you define two additional lines 1002, 1003 (it will be shared lines). The best is to define these lines on CP-7914 (lamps in the buttons indicate status of the line). When manager is using his line, assistant will see on his/her phone display that the line is used (special icons).
It is not very comfortable solution. Better is to use third party product like:
I understand. But how many lines do your users need to control? For "special users" you can install attendant console on their PCs, at it shows them status of the lines of other users.
You can also turn off "waiting calls" on your phones (only one incomming connection available), and when someone will try to transfer a call to the user, and this user has a active call, transfering party will get a busy tone. Users still will be able to make few outgoing calls.
There is no way that you can do what you want with just callmanager.There are 3rd party products that will enable you to do this but this would involve installing a software client on every PC and also spending money!
