It may not be related to your problem but I cannot see a dialer-group on
both Dialer 0 interfaces,

Asunto: ISDN Rookie Question?
Group,
What are the rules for using multiple ISDN dialer interfaces with
chap. I'm basically experimenting to find out what works and what doesn't.
The
config below always results in the ISDN layer 2 error message "user-busy".
The first dialer interface is meant to backup another interface and will
later
be reference by the backup interface and dialer persistent command. Right
now,
I simply want dialer0 to be able connect to the remote routers dialer0
interface.
