Application Initiated Outbound Call

Application	Libgcs7	State	Stack	Network
		NULL
gc_MakeCall( ) -->	CRN assigned IAM -->	DIALING	IAM -->	IAM -->
	GCEV_ALERTING <--	ALERTING	ACM <--	ACM <--
	GCEV_CONNECTED <--	CONNECTED	ANM <--	ANM <--

Or, if the ACM contains "no indication":

Application	Libgcs7	State	Stack	Network
		NULL
gc_MakeCall( ) -->	CRN assigned IAM -->	DIALING	IAM -->	IAM -->
			ACM <--	ACM <--
	GCEV_ALERTING <--	ALERTING	CPG Alerting event <--	CPG Alerting <--
	GCEV_CONNECTED <--	CONNECTED	ANM <--	ANM <--

This following scenario is also possible in ITU-T operation:

Application	Libgcs7	State	Stack	Network
		NULL
gc_MakeCall( ) -->	CRN assigned IAM -->	DIALING	IAM -->	IAM -->
	GCEV_CONNECTED <--	CONNECTED	CON <--	CON <--
