GCEV_ACCEPT_INIT_XFER_FAIL Termination event for gc_AcceptInitXfer( ) Associated with a call (CRN) The gc_AcceptInitXfer( ) function failed. GCEV_ACCEPT_XFER Termination event for gc_AcceptXfer( ) Associated with a call (CRN) Indicates that the function was successful, that is, the local party successfully accepted the call transfer request from remote party A. GCEV_ACCEPT_XFER_FAIL Termination event for gc_AcceptXfer( ) Associated with a call (CRN) The gc_AcceptXfer( ) function failed. GCEV_ACKCALL Termination event for gc_CallAck( ) Associated with a call (CRN) Indicates termination of gc_CallAck( ) and that the DDI string may be retrieved by using gc_GetDNIS( ). GCEV_ALARM Unsolicited event Associated with a line device (LDID) An alarm occurred on a trunk or a time slot. If enabled and allowed, GCEV_BLOCKED and GCEV_UNBLOCKED will also be generated for blocking alarms.

GCEV_ANSWERED Termination event for gc_AnswerCall( ) Associated with a call (CRN) Call established and enters Connected state. GCEV_ATTACH Termination event for gc_Attach( ) or gc_AttachResource( ) Associated with a line device (LDID) Voice or media handle was successfully attached to the line device. GCEV_ATTACH_FAIL Termination event for gc_Attach( ) or gc_AttachResource( ) Associated with a line device (LDID) The corresponding attach function failed. GCEV_BLINDTRANSFER Termination event for gc_BlindTransfer( ) Associated with a call (CRN) Events Generated when the call transfer has been successfully initiated in an unsupervised transfer. GCEV_BLOCKED† (enabled by default) Unsolicited event Associated with a line device (LDID) Indicates that the line is blocked and application cannot issue call-related function calls. Retrieve reason for line blockage using gc_ResultValue( ). GCEV_CALLINFO Unsolicited event Associated with a call (CRN) Generated when an incoming information message is received, for example, in response to a gc_SndMsg( ) function call from the remote side. GCEV_CALLPROC Termination event for gc_CallAck( ) Associated with a call (CRN) Generated when a call proceeding indication is sent out. GCEV_CALLSTATUS Termination event for gc_MakeCall( ) Associated with a call (CRN) Indicates that a time-out or a no answer (call control library dependent) condition was returned while the gc_MakeCall( ) function is active. GCEV_COMPLETETRANSFER Termination event for gc_CompleteTransfer( ) Associated with a call (CRN) Indicates that the original call has been transferred to the consultation call. Transfer completed successfully. Dialogic ® Global Call API Library Reference — January 2008 399 Dialogic Corporation
