What's wrong with this picture? The config looks correct to me but the darn thing wont dial.
Ideas anyone?
thanks

It looks like it is connecting, but dropping immediately.

Perhaps an authentication problem? debug ppp authentication

Another thought is that the original post shows dialer-group 1 but does not show dialer-list 1. It would help to know if dialer-list is configured and if so what it has.

rick,
dialer list is configured.
dialer-list 1 protocol ip permit

ok ... get auth failure but username and passowrd is correct on both client router and the one they dial into.
What else can it be?

check out the multilink string used on either sides.
It would help if debug q931 and q921 outputs are taken.
