Draytek FXO4P voice network module

FXO4P - Analogue FXO Module The FXO module provides four inputs for analogue (POTS) lines. This allows integration of your existing phone lines into the Vigor IPPBX3510. You then can continue to use your analogue lines, but also enjoy the advanced features of the Vigor IPPBX and deploy IP extensions. This is a true hybrid solution for legacy systems. Incoming calls on analogue lines or VoIP can be distributed to extensions exactly as you wish, and outgoing calls made over analogue line or your VoIP trunk according to your own preferences.
