A system and method for establishing a long distance call connection between call stations (10, 20) over the PSTN (200) initiates a call connection reque st 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 requirin g 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. |
