The element (P) has two interfaces (INT1, INT2) to exchange a signaling message with a communication agent (UA1) e.g. terminal, and with other signaling element (S) e.g. session initiation protocol proxy type element, respectively. A processor (TRT) receives another signaling message on one of interfaces and copies the data contained in the path towards a service-route of the message from the other interface. The processor receives an initial signaling message on one of interfaces and copies the data contained in a route to a record-route of the message from the other interface.
