The OpenVox A400P11 offers a PCI interface for one FXS port and one FXO port. A modular design means you can swap out and mix up the card's analog ports as your system requires. The OpenVox A400P11 hosts up to four FXS and FXO ports.
Interchange the ports with OpenVox FXS-100 and FXO-100 modules, or Digium X100M and S100M modules. The OpenVox A400P series is compatible with open source and proprietary platforms such as Asterisk, trixbox, Elastix and more.
