BRI

A BRI Media Gateway typically connects residential, SMB or enterprise telephony equipment to the service provider VoIP network using an ISDN BRI connection. This is done by converting the existing TDM digital ISDN BRI interfaces to VoIP. A BRI gateway can connect to existing legacy PBXs using BRI interfaces, providing a trunk connection into the PSTN, or alternatively connecting BRI phones directly into the VoIP network using BRI interfaces.
