A method for establishing a communication session between a first client (C1) located within a first network (N1) and a second client (C2) through a signaling server (S) located within a second network (N), consisting of a step of binding together a first address and a second address of the first client within an address translation device, by having the first client transmit registration signaling messages. The server: saves an incoming signaling message sent from the second client, responds to the registration message that follows with a reply message (RN) requesting that a new registration message (MN+1) be sent using the TCP protocol, and delivers the incoming signaling message (MI) after the new registration message has been received.
