asterisk users - Jul 2008 - CallerID in The Netherlands with TDM11B

For quite a long time already my CallerID stopped working (maybe even when 
i upgraded from Asterisk 1.2 to Asterisk 1.4). I am using a TDM400P card 
(in TDM11B config) with one FXO and one FXS port.

Tried googling for some more recent examples of Asterisk config files for 
use in The Netherlands, but without success.

Anybody here that has this working?

When a call comes in i see this on the asterisk console :

   == Starting post polarity CID detection on channel 4
     -- Starting simple switch on 'Zap/4-1'
[Jul  8 11:58:55] WARNING[9539]: callerid.c:219 callerid_get_dtmf: 
Couldn't detect start-character. CID parsing might be unreliable


This is in my /etc/zaptel.conf :
fxoks=1
fxsks=4
loadzone=nl
defaultzone=nl

This is in my /etc/asterisk/zapata.conf :
