Hi Sir or Madam at Avaya,

We recently acquired Tsapi client SDK 8.1. We want to use SingleStepTransferCall functionality. We would like to transfer the call as soon as it arrives.

However we are not able to perform single step transfer call, after we receive the CSTA_DELIVERED event. On the code side we are using AttSingleStepTransferCall and CSTAEscapeDevice to perform the transfer. And both returned true. Please see attached BlindTransferCall.txt.


From TSAPI Spy, we saw that single step transfer call resulted into a UniversalFailure invalidCstaDeviceIdentifier. Please see attached TsapiSpylog.txt, 07/03/19 14:02:42.206 time stamp for transfer and 07/03/19 14:02:42.209 for the failure.

Note that 13602 is a valid number, we are able to perform a single step transfer upon CSTA_ESTABLISHED event.


We would like to know under what conditions should we be able to perform single step transfer upon delivered event. Because when we receive the delivered event, the device state is alerting and according to the documentation, Tsapi is able to perform single step transfer at alerting state.

It seems that attachments and editing doesn't work

bool BlindTransferCall(long acsHandle, long callID, String^ connectionDeviceID, short connectionDevIDType,
String^ deviceToTransfer, String^ privateData) override
{
ConnectionID_t connection;
RetCode_t rc;
//uui data section;
ATTPrivateData_t attPrivateData;
DeviceID_t transferVDN;

//set private data
(void)strcpy_s(attPrivateData.vendor, "VERSION");
attPrivateData.data[0] = PRIVATE_DATA_ENCODING;

attMakeVersionString("3-8", &(attPrivateData.data[1]));
attPrivateData.length = strlen(&attPrivateData.data[1]) + 2;

//set connection data
connection.callID = callID;
strcpy_s(connection.deviceID, (char *)Marshal::StringToHGlobalAnsi(connectionDeviceID).ToPointer());
connection.devIDType = (ConnectionID_Device_t)connectionDevIDType;
strcpy_s(transferVDN, (char *)Marshal::StringToHGlobalAnsi(deviceToTransfer).ToPointer());

// Prepare for blind transfer
rc = attSingleStepTransferCall(&attPrivateData, &connection, &transferVDN);

// Perform actual transfer
rc = cstaEscapeService(acsHandle, 12, (PrivateData_t *)&attPrivateData);

if (rc >= 0)
return true;
else
return 0;
}

You must answer the call before you can transfer it (i.e. a ringing call can not be transferred to a ringing call), one of the two calls must be in a stable answered state, and if the other call is unstable (ringing), it must be an outbound call from one of the transferring devices (stations).
