摘要:
Method of setting up a communication session (fm) between a calling communication client (C1) and a called communication client (C2), through a communication network (SN1, SN, SN2) comprising at least one address translation equipment (NAT1, NAT2). It comprises steps for transmission of signal messages (fs), transiting through address translation equipment and enabling interchange of physical addresses of communication clients to set up the communication session. This method is characterised in that at least one client transmits at least one signal message containing a physical address in a first location, and coded information containing this particular physical address in a distinct second location.
