The USB tap recording requires the RJ9 connector for the curly cord
and the flat phone cable (with standard wiring).
We can record with the USB tap when using the handset.
The headset does not have the standard RJ9 connections .
To record the headset, conversion is needed as it uses
2.5MM STEREO SOCKET
2.5MM STEREO JACK
and no RJ9 as required by the USBT tap .
The converters are not suppplied by Datatex.
