So how do I connect to a PSTN line by SIP? :-)

SS7 is the basis for the entire world's telephone network signalling. 
New forms which run over IP are being deployed. Even if the last 
remaining fragments of the PSTN are shut down, and everything on land 
lines is IP based, SS7 is still the core protocol for the cellular 
networks - GSM-A, for example, is built upon SS7. Of course, its always 
possible WiMAX might shut those down too. :-)
