It's a good habit to reboot the router when you first set up the isdn link
or have changed configurations. The TEIs you got there may not be working
even though they are "valid" and "established". I've worked with ATLAS 800
before and sometimes it gave you big headache.

If you have not gotten this resolved yet, it would be helpful to see
the results of debug isdn q931 and perhaps the results of debug ppp
authen.
