gc_RejectXfer( ) — reject call transfer request Parameter Description crn call reference number for the call between the remote transferring party A and the local party that received the call transfer request reason specifies the value of rejection reason, which may be protocol-specific. For H.323/H.450.2, the defined rejection reasons are: parmblkp ignored for IP After successfully rejecting the request, the call state of local party B or C returns to its original call state (GCST_CONNECTED). When receiving the GCEV_REQ_XFER event, the application can obtain the information for the rerouting number or address from extevtdatap in the METAEVENT data structure. Because the extevtdtatap is managed by GCLib/CCLib (allocated/deleted automatically), the user application does not need to allocate or deallocate extevtdatap. Preceding Events GCEV_REQ_XFER unsolicited event, notifies application at the local party receiving the call transfer request from remote party A Termination Events GCEV_REJ_XFER indicates that the gc_RejectXfer( ) function was successful, that is, the local party successfully rejected the call transfer request from the remote party GCEV_REJ_XFER_FAIL indicates that the function failed. For more information, see the “Error Handling” section in the Dialogic ® Global Call API Programming Guide.
