Important: When the boss/secretary function is switched on, incoming calls are also rerouted to the secretary when the function call forwarding for subscribers is enabled on the boss telephone. On the other hand, a call from the secretary to the boss telephone is rerouted if call forwarding is enabled or signals busy if do-not-disturb is enabled.
Note: On the secretary's telephone, in addition to the boss key, it is also a good idea to configure a speed dialling key for the phone number of the boss telephone in order to keep track of whether it is busy or not.
