12 or 24 analog line recording external board for Soft PBX


  • EBS-FXO HI 120, with 12 analog recording interfaces
  • EBS-FXO HI 240, with 24 analog recording interfaces


The primary function of the EBS-FXO HI SPX is the passive recording (high-impedance) of PBX extensions or analog telephone lines in systems that use open code software. EBS-FXO HI SPX modules are connected in parallel with the channel, recording in a manner that is imperceptible to the user and without degrading call audio. It reports to the host the ring signal, inversion of polarity, audio events, answering and hang up of the call, without the need for integration with the PBX to begin and end the recording.
