A method relating to telecommunications wherein a call is connected between two subscribers, wherein the call is billed to a third subscriber, wherein the telephone of a first subscriber is connected to the telephone of a second subscriber via a standard telephone network, wherein the first subscriber dials a subscriber number, preferably preceded by a prefix, that leads to the third subscriber and dials a subscriber number that leads to the second subscriber, wherein the telephone network is caused to connect the call to a telephone network connected computer unit (4) that forwards the call to said second subscriber such as to connect said first subscriber with said second subscriber, and wherein the call between the first and the second subscriber is billed to the third subscriber, wherein advertisements are transmitted on the call connected between the first and the second subscriber. The invention is characterized in that when one of the first and the second subscribers enters a code or the like through the keypad of the telephone concerned during an ongoing call, said computer unit (4) is caused to sense said code; in that when sensing the code, the computer unit is caused to interrupt transmission of advertisements during the course of the call; and in that the computer unit is caused to bill the remainder of the connected call in accordance with fixed telephone charges.
