An approach for providing telephony services over a data network (231) is disclosed. A communication system includes a gateway (201) that receives a signal to establish a call with a called (229, 233) station from a calling station (237, 239) in a telephone network, such as a Class 3 network (205), associated with one of a plurality of customers. The gateway (201) generates a message according to a prescribed application layer protocol to establish the call with the called station (229, 233) over the data network (231). The message includes an alias host address identifying the one customer. The system also includes a server (225) that receives the message from the gateway and to route the call to the called station (229, 233) based upon the alias host address.
L'invention concerne un procédé qui permet de fournir des services téléphoniques dans un réseau de données (231). Un système de communications comprend une passerelle (201) qui reçoit un signal permettant d'établir la communication avec une station appelée (229, 233) par une station appelante (237, 239) dans un réseau téléphonique, tel qu'un réseau de classe 3 (205), associé à un client parmi une pluralité de clients. La passerelle (201) émet un message selon un protocole de couche d'application déterminé pour établir la communication avec la station appelée (229, 233) dans le réseau de données (231). Ce message contient une adresse IP pseudonyme identifiant ledit client. Par ailleurs, ce système comprend un serveur (225) qui reçoit le message à partir d'une passerelle et qui achemine l'appel à la station appelée (229, 233), sur la base de l'adresse IP pseudonyme.
