6.1.4 GWCall::callIPOffered

The application waits for either a GCEV_ALERTING or a GCEV_CONNECTED event from the PSTN.

In the case of GCEV_ALERTING, the application calls processEvent(USR_ACCEPT) from the IPCallControl module and the call state transitions to callIPAccepting.

In the case of GCEV_CONNECTED, the application calls processEvent(USR_ANSWER) from the IPCallControl module and the call state transitions to callPSTNConnected.

If the application receives a GCEV_CALLPROC or a GCEV_PROCEEDING event, it ignores the event and remains in the callGetIPOffered state.

If the application receives a GCEV_DISCONNECTED or a GCEV_TASKFAIL event, it sets the drop reason by calling getResultValue( ) from the GCCallControl module. The application then calls processEvent(USR_DISCONNECT) from the IPCallControl module if the PSTN was the event source, or from the PSTNCallControl module if the IP was the event source. The call state transitions to callDropping.
