ABSTRACT:
A method of telephone call, in which if a subscriber is unable to answer an expected call to this telephone due to a conference, business trip, vacation or temporary absence, the reason of not answering is registered with an electronic switching unit from the subscriber's telephone. When an incoming call arrives for the subscriber's telephone, the electronic switching unit decides whether the subscriber's telephone is advisable to call it on the basis of the registered subscriber status data. If the reason for no answer is registered, the calling subscriber is informed without calling the other subscriber by an audible signal or a recorded message.
