Ladite opération comprend les étapes consistant à : recevoir, à partir du premier terminal utilisateur, une seconde valeur unique et un second pseudonyme qui sont indiqués par le biais d'un code QR identifié par un premier terminal utilisateur ; vérifier la validité du code QR à l'aide de la seconde valeur unique reçue et du second pseudonyme ; identifier une adresse réseau d'un second terminal utilisateur à l'aide de la seconde valeur unique du code QR dont la validité a été vérifiée ; transmettre un message de demande d'appel au second terminal utilisateur à l'aide de l'adresse réseau identifiée ; recevoir un message d'acceptation d'appel à partir du second terminal utilisateur et générer un canal de communication en ligne entre le premier terminal utilisateur et le second terminal utilisateur en réponse à la réception du message d'acceptation d'appel.
