The legacy telephony interface to the open source Asterisk PBX is the Digium Asterisk Hardware Device Interface (Dahdi). The legacy interfaces can be FXS, FXO, ISDN BRI, T1 over USB, T1, E1 ISDN PRI and TDMoE (Dynamic Dahdi) ports. This Webmin module aids in configuring the legacy hardware devices to Asterisk PBX. Webmin was chosen because Webmin is a mature web based GUI platform that concentrates on the hardware side of a server. Webmin allows controlled secure root access to the hardware. Other web based GUIs concentrate on the software side of configuring Asterisk and do not provide root access directly.
