Interesting. For us in Sweden it is actually cheaper to connect to our 
carrier through PRIs than through VoIP. We have two fibre pairs instead of 
one, and it is still cheaper. Well, they had six pairs since that is the 
minimum cables they install.

Add to that the lower latency etc of a tdm solution. I guess it is a scale
thing - when lots (most?) companies are connected via isdn technology the
cost goes down.
