the same config twice.  Here are the configs for both routers.

Brian,
           A couple things I noticed in looking at the configs  See
Inline..
I'm really confused..  Is this an active/production circuit or a
lab setup.   You have numerous errors in this configuration.  First
thing I
want to ask is does the both devices have "active"
Layer 1 and Layer 2 connectivity?   Based on the what you're trying to
do
using a teltone ISDN sim and two ISDN routers back-to-back
here's a revision of your configs that should work..  Also here is a
link
you should check out..

NT:   The other router is configured to for r2...  here you have r5as
the
hostname.
As well the account of the called router here should be R1...

> ppp callback accept

NT:  If this is the calling router then it;s going to request the
callback.
The callback server(router) accepts the callback.

NT:   Only the router(acting as the callback server) requires the
class-map
which is used to tell the router
how and who is allowed to recieve the callback once authenticated.
