Are you using PAP or CHAP authentication?  It looks like the type of
behavior I had when I had my authentication wrong.  Turn debug on in
your pppd options file and watch the /var/log/ppp.log file when your are
connecting, 'tail -f /var/log/ppp.log'.  You should see the username and
password being sent to the remote host. If it is wrong you will see a
LCP request from the remote host to hangup.  I am no expert but just
speaking from experience.
