Abstract: A method relating to telecommunications in which the telephone of a first subscriber is connected to the telephone of a second subscriber via a standard telephone network and the call is billed to a third subscriber. The first subscriber first dials a subscriber number, preferably preceded by a prefix, which leads to the third subscriber and then dials a subscriber number that leads to the second subscriber. The telephone network connects the call to a telephone-network-connected computer unit that forwards the call to the second subscriber to connect the first subscriber with the second subscriber. The call between the first subscriber and the second subscriber is billed to the third subscriber, and advertisements are transmitted on the call connected between the first and second subscribers.

Abstract: A method and apparatus for forwarding and billing a telephone call, wherein a first subscriber telephone is connected to a second subscriber telephone via a standard telephone network and a third subscriber is billed for the call. The first subscriber dials a prefix followed by a subscriber number which leads to the third subscriber and also dials a subscriber number which leads to the second subscriber. The prefix causes the telephone network to connect the call via the telephone network to a computer unit that is associated with the third subscriber and that is connected to the telephone network. The prefix also causes the computer unit to forward the call to the second subscriber via the computer unit, to connect the first subscriber with the second subscriber. Detection of the prefix by the telephone network causes the network to bill the call between the first and the second subscriber to the subscription of the third subscriber.
