Computer telephone integration (CTI) server having dial-up network access. By providing increased integration between a CTI server and the public switched telephone network (PSTN), enhanced features can be provided to users of the CTI server for accessing on-line services. The server connects with on-line service providers either through a PSTN office or a dedicated data network which is associated with the PSTN. The dedicated data network is usually either a frame relay or an asynchronous transfer mode (ATM) network. The CTI server can also be connected to customer premises equipment (CPE) through a PSTN office to provide CTI services to dial-up users. Additionally, the CTI server can provide simultaneous access to multiple service providers which allows better integration of CTI services and services provided by Internet service providers, |
