I am not sure exactly what you are asking. If you have a previous post which Kyle answered I would suggest just posting back to it.
However if you want to send data across TCP in LabVIEW there are some TCP VIs that are quite easy to use. You open a connection, write and read from that connection, and then close it. However data send over TCP using the TCP VIs is sent as a string, not as "voice" however I am not sure what data type you are currently using.
