Yes, it's strange. But I find no mention on answer supervision in the 
NT1Plus manual (NT1Plus is the hardware device the Telco installs 
when you ask for an ISDN line). Where should I ask for answer 
supervision? The Telco? That sounds very difficult in Italy... they 
have no technical call centers. Almost only sales.

But if the line should provide those "analog" billing pulses... do 
you think could be possible to intercept them?
