With the help from James.Zhu, we have managed to install one B400p and one A400p card in one server. Below are some key points:
Download and install Bristuff from openvox download version, remember to apply the patch before compiling, then asterisk, zaptel, libpri will auto install.
After that configure you zaptel.conf:
# Span 1: ztqoz/2/1 "quadBRI PCI ISDN Card 1 Span 1 [TE] (cardID 7) Layer 1 DEACTIVATED (F0)"
span=1,1,1,ccs,ami
# termtype: te
bchan=1-2
dchan=3
After that remember to load qozap.ko driver first before wctdm.
If any one has any problem can follow up this post then I will try to answer your question.
