In my site (bsi.com.br) I have done a small shell program(pppmon)
that does this every minute.
1) ps -ax | grep ppp....
2) find what ips are connected to ppp interfaces
3) ping -c 1 ip (if does not respond, kill -1 pid...)

In the case the modem (hungs up, or the ppp locks) the user is 
disconnected...
