        'mCall will be in onHoldPendingTransfer state , ConsultCall will in dialtone
        If mCall.SetupTransfer() Then
            Sleep(1000)
            bnSwapHold.Enabled = True
            BnTransferComplete.Enabled = True
            BnThreeWay.Enabled = True
            'use ITAPILine.ConsultCall to obtain the consultation call.

You can read can't you? What part of "'SetupTransfer' is not supported by the device" is difficult to understand??

It'll telling you that your modem doesn't support transferring calls.

I can read but the problem is, this device is mobile phone. So in general we know that it can transfer call,but still i am facing the problem.

It doesn't support it in a method that TAPI supports!
