4, 8 or 12 analog line external boards


  • EBS-FXO 40, with 4 FXO interfaces + 4 VoIP channels
  • EBS-FXO 80, with 8 FXO interfaces + 8 VoIP channels
  • EBS-FXO 120, with 12 FXO interfaces + 12 VoIP channels


The EBS-FXO was developed for CTI applications that require analog trunking. Added value platforms, Audible Response Unit (IVR), Telemarketing, Voice Mail, Conference, IP PBX, and Help desk, among other items, are examples of applications in which the EBS-FXO can be used.

Its voice resources, which include detection of voice mail, detection and suppression of DTMF and AGC, call progress, reproduction and recording of audio messages, detection of fax signals, among other items, in addition to echo canceling, are performed in the hardware without consuming the processing capacity of the host. This robust architecture allows for the use of the EBS-FXO in high density applications using servers with less density.
