gc_AcceptInitXfer( ) — accept request to initiate a supervised transfer Preceding Events GCEV_REQ_INIT_XFER unsolicited event, notifies application at party C of the initiate transfer request from remote party A Termination Events GCEV_ACCEPT_INIT_XFER indicates that the gc_AcceptInitXfer( ) function was successful, that is, party C successfully accepted the initiate transfer request from remote party A GCEV_ACCEPT_INIT_XFER_FAIL indicates that the function failed. For more information, see the “Error Handling” section in the Dialogic ® Global Call API Programming Guide. Cautions The gc_AcceptInitXfer( ) function can be called only when the call is in the GCST_REQ_INIT_XFER call state. Errors If this function returns
