asterisk users - Feb 2007 - cannot get whole DNID with ISDN line

Hi,
I have an Asterisk 1.2.9.1 with chan_misdn 0.3.1-rc23 and a beronet 
octoBRI on a Debian box I have to set up instead of an old legacy PBX.
My problem is I get only the base DNID and not the extensions (the last 
two digits) in Asterisk but the old PBX got all the DNID number so I 
think it is the card.
Is there anybody experiencing a problem like this? How can I solve it? 
Any ideas?

TIA
