       The vpbecho utility performs a simple test of Voicetronix hardware.  It exercises the card base functions
       including the audio path, ring and hook detection.

       FXS  (station)  ports  will record 4 seconds of audio when the handset is lifted, then play back what was
       recorded.

       FXO (trunk) ports will answer after the second ring, then record 4 seconds of audio and  play  back  what
       was recorded.
