The present invention provides a Computer Supported Telecommunications Applications (CSTA) protocol-based service delivery method, which includes: obtaining a switching function service that carries voice parameters; and sending the switching function service that carries voice parameters down to the switch side. The present invention also provides a CSTA-based service execution method, a Personal Computer (PC), a switch, and a voice service system. In the present invention, when the PC sends a switching function service to the switch, voice parameters can be carried in the switching function service. In this way, when the switch obtains the switching function service with voice parameters, the switch can play voice according to the voice parameters. Therefore, the present invention enables play of voice without modifying the existing service process, thus, simplifying the implementation.
