Hi Lawrence,

I don't believe this is standardized in the way you're trying to use it. Typically receiver signals would be GREEN and BLACK while transmitter signals are WHITE and RED. Your description sounds more appropriate to a 3.5mm TRRS jack. You can still use the RJ9 with the understanding that other phones that plug in may not be compatible.

Best regards,

Hi Jett,

Telephone host directly connects to PCM2912AEVM

Not using the handset on the phone

The sound signal is obtained from the computer

Will this configuration work?

Hi Jett,

The sound signal is not timely

Must be played back after recording through computer

Is there a way to answer calls instantly through headphones?

Hi Lawrence,

There is no GUI for this device because everything is handled over USB as a USB audio device. You can operate the device through typical Windows audio settings.

Allen,

Please give more detail on your issue.

Best regards,
