I thought that was the idea of using ISDN. We do it with PBXs all the 
time, setting the callerid to your DDI number or just set every call to 
appear to call from the main line. As for getting the so-called 
'witheld' number, it's a feature at the signalling level. Over here, 
when you text using a mobile phone with a 'witheld' number, it still 
shows up at the receiving end. If these are security problem, it's the 
ISDN protocol's fault. The author is obviously barking up the wrong tree.
