Currently, in order to determine the handling of a subscriber initiated call in telecommunication networks we have to write applications using specific protocols to access Call Control functions provided by network elements. This approach requires a high degree of network expertise. We can also use the OSA gateway approach, invoking standard interfaces to gain access to call control capabilities, but these interfaces are usually perceived to be quite complex by application IT developers. Developers must have advanced telecommunication skills to use Call Control OSA interfaces.

This TS specifies a Parlay X Web Service, Call Notification, for handling calls initiated by a subscriber in the network. A (third party) application determines how the call should be treated. The overall scope of this Web Service is to provide simple functions to application developers to determine how a call should be treated. It is possible to request to end the call, continue the call or re-route the call. Optionally, it is also possible to request the media type(s) when the action is to re-route the call. It provides, for example, the capability to route a call to an IVR in order to play a video stream to the calling subscriber. A service policy determines if multimedia application control is supported.
