Defines signalling protocol for supporting the Recall supplementary service (SS-RE) at the Q reference point between Private Integrated Services Network Exchanges (PINXs), connected within Private Integrated Services Network (PISN). This is a supplementary service providing for the re-directing of a transferred call back to the served user should the call be unanswered.
