Calling operations from the entrance telephone set are performed with a prefix indicating call of the type "called party pays" with the entrance telephone set accepted for initiation of such calls. Alternatively, subscribers connected to the entrance telephone system are treated as "020-subscribers" with regard to call charges for calls from the entrance telephone set. In another embodiment, subscribers connected to the entrance telephone system are given a secondary telephone number for entrance telephone calls on which the call charges are debited for calls from the entrance telephone set. A still further embodiment a sponsor/advertiser is given an opportunity to pass on a message to visitors when calling, and to pay for this service at least the call charges. The call is preferably charged only after acceptance of the call from the called party, and with disconnection, preferably without any call charge, if the called party does not accept the call.
