Abstract
The present invention discloses numerous implementations for IP-based call processing systems that can selectively control an outgoing call initiated by a source device to a destination device. The call processing system communicates with a Service Switching Point (SSP) associated with the source device and determines whether to effect control of the outgoing call. It could determine to effect control of the outgoing call for many reasons including to convey a media message to the source device, to implement a call feature or to manage call restrictions. Upon determining to effect control of the outgoing call, the call processing system causes the SSP to initiate a media connection between the source device and the call processing system. The call processing system can then utilize the media connection with the source device to perform functionality for the outgoing call prior to and/or during the outgoing call.
