The method involves sending a call request from a calling terminal to a called terminal via a signaling unit to enable a data exchange between the terminals, sending useful data between them and recording an identifier and storing or outputting the identifier in the signaling unit. The called terminal is in a data packet transmission network. The signaling unit signals using a protocol specified for data packet transmission network transmissions. The method involves sending a call request from a calling terminal to a called terminal (36) via a signaling unit (44) to enable a data exchange between the terminals, sending useful data between them and recording an identifier and storing or outputting the identifier in the signaling unit. The called terminal is a terminal in a data packet transmission network and the signaling unit signals in accordance with a protocol specified for data transmission in a data packet transmission network. Independent claims are also included for the following: (1) a terminal with a unit for connection to a data packet transmission network (2) and a signaling unit (3) and a program for implementing the functions of a terminal or signaling unit. |
