Appendix A - Call Control Scenarios
401
When a transferred call is disconnected, the network informs the TBCT controller
by sending a NOTIFY message with the Network Call Reference Value. The
application receives the GCEV_EXTENSION event (with ext_id =
GCIS_EXEV_NOTIFY) event.
The following figures provide line diagrams that illustrate the operation of this
feature. Figure 7 shows the invocation of TBCT with notification in which both
calls answered.
