Well, I just answer myself here:
Since the ISDN PBX is just the same as ISDN phone as far as the
asterisk is concerned, NT mode on the ISDN card should be used as
well.
The difference is that the phone uses p2mp (point to multi point)
protocol, as the PBX uses p2p (point to point) protocol.
Using the bri_net signalling instead of bri_net_ptmp solves the problem.
