Technical Examples

In a method for digitally transferring information via telephone connections, in which a receiver registers the sender's telephone number, the receiver is assigned a plurality of callable telephone numbers. Each time a specific sender dials a callable telephone number, the receiver registers this as an individual piece of digital information associated with the called telephone number. A piece of total information is formed from the individual pieces of digital information.
