Method, system, network and computer-readable media for controlling outgoing telephony calls to convey media messages to source devices

摘要

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 a media message is to be conveyed to the source device. It could determine a media message is to be conveyed to the source device for many reasons including to convey a message related to a call feature, to prompt a user to provide authorization data, to alert a user of particular information or to provide an audio element to the source device prior to establishing the outgoing call. 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 to convey a media message to the source device.
