---------------------------------------------------------------------- 
Problem still happens when using DAHDI-Linux 2.2.0.2 and DAHDI-Tools 2.2.0.
The problem only happens when all these criteria are met:

- E1 (ccs,hdb3)
- ISDN protocol (I'm using signalling=euroisdn)
- VPMADT032 is physically present

When the VPMADT032 is physically removed the problem no longer happens.
Actually I had to remove it in order to get a stable link with the telco.
Also tried:

echo 0 > /sys/module/wcte12xp/parameters/vpmsupport

But the problem still happens.
