Rejecting a Call Waiting Call
If you receive another call while you are already making a call and you do not want to speak with the second caller, or you do not want to interrupt the first call, you can reject the call waiting call. The caller receives a busy signal as long as no other phones are called.
If a call waiting call is signalled, proceed as follows:
1.Press the Flash key or the Query key.
2.Dial 0.
Note: You can also use this function on analogue phones, where it can be performed via the T-Net function key/menu (optional, see manual for the phone).
Note: On ISDN and system phones, this function is performed via an existing function key or via the menu (optional, see manual for the phone).
