A third-party call setup gateway (90) is provided for setting up bearer channels (60) through a switched telecommunications system, such as a PSTN, by controlling an associated switch (41). The call setup gateway (90) has an interface onto a computer network, such as the Internet, that is accessible to users of the telecommunications system. In a preferred arrangement, a user A wishing to place a call to user B gets the details of B's current telephone number from a "phone page" (41) on B's website and then sends this telephone number together with A's own telephone number, to the gateway (90). The gateway (90) then commands the switch (41) to establish a call between A's telephone and B's telephone.

Une passerelle d'établissement d'appel par un tiers (90) permet d'établir des canaux porteurs (60) au moyen d'un système de télécommunications commuté, p. ex. un RTPC, par commande d'un commutateur associé (41). La passerelle d'établissement d'appel (90) a une interface avec un réseau informatique, p. ex. l'Internet, qui est accessible aux utilisateurs du système de télécommunications. Dans une version préférée, un utilisateur A désireux de faire un appel à l'utilisateur B obtient les détails relatifs au numéro téléphonique de B sur une « page téléphonique » du site Web de B, puis envoie à la passerelle (90) ce numéro téléphonique conjointement avec le numéro téléphonique de A. La passerelle (90) commande ensuite au commutateur (41) d'établir l'appel entre le téléphone de A et le téléphone de B.
