SKU: B400P

4-port ISDN BRI PCI

The OpenVox B400P is a half length ISDN (Integrated Services Digital Network) BRI (Basic Rate Interface) PCI (Peripheral Component Interconnect) card. The B400P provides a four ISDN BRI S/T ports, which makes it an ideal cost effective option for small to medium sized enterprise applications. OpenVox are a Fonality® Authorized / Certified Ecosystem (FACE) partner and the OpenVox B400P is officially certified for use with Trixbox®. Standard PC (Personal Computer) hardware can be used along with B400P cards to provide a low cost migration path from legacy ISDN PBXs towards an Open Source IP PBX based solution. The Although developed primarily for Open Source IP PBX Asterisk® based applications, the B400P can be used for any Linux applications/systems that require ISDN connectivity, e.g. Linux ISDN firewalls, VoIP gateways and routers.
