4, 8 or 12 analog line external board for Soft PBX


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


The EBS-FXO SPX was developed for applications that use open code software and require analog trunking. Added value platforms, Audible Response Unit (IVR), IP, PBX, Telemarketing, Voice Mail, Conference, and Help desk, among other items, are examples of applications in which the equipment 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 SPX in high density applications using servers with less processing capacity and low cost.
