The invention provides systems and methods in which an incoming call port is looped back at a switch and, under control of a call segment controller, is directed to applications and/or other termination points to provide enhanced calling services. According to a preferred embodiment, the call segment controller is provided with initial call instructions to initially direct an incoming call. The call may then be directed to an application which interacts with the call to determine further call instructions. These further call instructions are passed to the call segment controller to further process the call. Under control of the call segment controller the call may be directed to multiple termination points, including redirection to the application to provide subsequent interaction with the call.
