Sorry, there are no analog softmodem drivers yet. I have been living in
isdn land for too long and forgot about the analog modems. There are 
indeed drivers for ppp over isdn direct but no softmodem for analog calls.

We have solved this by routing those calls to our old pbx (over an E1 
PRI) from which a couple of BRI:s go to isdn modems with analog 
capabilities.

So, you should be able to hook up your old PRI equipment to Asterisk, i.e.

     PSTN  -PRI-  Asterisk  -PRI-  Old_equipment
                     \
                      ---lan--- sip stuff

This is sort of what we are doing. As far as I can tell the digital 
channels are passed transparently from one pri to the other once a call is 
set up. We can do both analog termination and direct isdn connections.
