CA 2420245

A system and method for establishing a long distance call connection between call stations (10, 20) over the PSTN (200) initiates a call connection request from a desktop application (40) adapted to operate locally on a user workstation (30). The desktop application communicates call connection information to a long distance service provider server (60) without requiring a web browser when a request is initiated by a user. Call connection information is processed by the long distance service provider server and an information packet is sent to a call controller (70), to effect a call connection over the PSTN via a TDM toll switch (80). A communication connection with the long distance service provider server is automatically established by the desktop application when a request is initiated, and subsequently released when the call connection request is received and processed by the long distance service provider.

L'invention concerne un système et un procédé permettant d'établir une communication longue distance entre des stations (10, 20) de communication, à travers un RTPC (200). Dans ce système et ce procédé, une demande de communication est lancée à partir d'une application (40) de bureau conçue pour fonctionner localement sur un poste (30) de travail utilisateur. Cette application de bureau transmet l'information de communication à un serveur (60) de fournisseur de service longue distance, sans qu'un navigateur Web ne soit sollicité lorsqu'une telle demande est lancée par un utilisateur. L'information concernant la communication est traitée par le serveur du fournisseur de service longue distance et un paquet de données est envoyé à un contrôleur (70) d'appel afin d'établir une communication dans le RTPC via un commutateur (80) interurbain à multiplexage temporel (TDM). La communication avec le serveur du fournisseur de service longue distance est établie automatiquement par l'application de bureau lorsqu'une demande est envoyée, puis libérée lorsque la demande de communication est reçue et traitée par le fournisseur de service longue distance.
