Handling an Incoming Call This section discusses how the demo application handles incoming calls.
IP Gateway (Global Call) Demo Guide for Linux and Windows 26 Once the destination gateway has answered the H.323 call, the IP Gateway (Global Call) demo connects the PSTN call to the IP call. An audio path is now established between the PSTN call and the destination IP station.
6. Demo Details 27 The threads are created as follows: • The first (main) thread is created by the demo application to get the keyboard input. • The second thread is an SRL thread, created as a result of the demo application calling sr_enblhdlr( ) in Windows.
IP Gateway (Global Call) Demo Guide for Linux and Windows 28 • Calculates the logical board and channel and saves them into Session.pstnParams • Closes the board, by calling dx_Close( ) or dt_Close( ) .
6. Demo Details 29 • Calls gc_OpenEx( ) which opens all IP devices, returns the IP LineDevH , and saves it in Session.ipParams • Saves the channel number in the global array HandleToChannel[ ] according to the LineDevH handle 13. The application main() function calls waitForKey( ) , to receive keyboard input.
IP Gateway (Global Call) Demo Guide for Linux and Windows 30 3. Otherwise, the application calls gc_GetUsrAttr( ) and then calls either ipGetEvent( ) to process the IP event, or pstnGetEvent( ) to process the PSTN event. 6.5.3. Handling Application Exit Events Normal application exit events don’t enter the SRL.

6. Demo Details 33 2. In PSTN_OFFERED the application waits for GCEV_CONNECTED from the IP side. When the application receives GCEV_CONNECTED it calls: • gc_Extension( ) to get the call information .
IP Gateway (Global Call) Demo Guide for Linux and Windows 34 2. When the application receives GCEV_DROPCALL from the IP side, it calls gc_Extension( ) to get the RTCP information. When the application receives GCEV_EXTENSION the application calls gc_ReleaseCall( ) and the state transitions to GATE_NULL.
