You should always use PPP authentication with dialer interfaces. Say you
have two dialer interfaces on a router with one bri interface and another
router calls in. How is the router going to know which dialer interface to
bind the call to? It needs ppp authentication to get the remote name and
then searches for a dialer interface with "dialer remote-name" that matches.
Turn on "debug isdn q931" on the router with the dialer interfaces without
ppp authentication configured and try to call into it. You should see that
the call is disconnected due to being "unbindable".
