You would need to load either the "zaphfc" or "qozap" driver. Depending on what BRI card you use. wct4xxp is for the quad E1/T1 card from Digium and wcfxs is for the TDM400P. > Here is my problem: > I connected the BRI phone to the BRI Card and the Q921 Layer was up.

Just asterisk with bristuff, an old NTBA for termination and power on the s-bus between the BRI card and the phone, card is hfc-s and of course a ISDN cross-over cable (the quadbri and octobri would take care of both power, termination and crosslink, so they don't need that). But you need a HFC based BRI card and you need to load the correct modules. wct4xxp and wcfxs have nothing to do with BRI support.
