I've had the exact same problem. If you put dialer maps on both ends,
either end can bring up the link, but pings will fail. It does not matter
that authentication is working fine, --it does not matter if you have no
authentication on at all, pings just will not go thru. Now if you take off
one of the dialer-maps, -and put in a dialer string, then he can't callout,
but when he gets a callin, they can ping each other just fine.
I used to teach ACRC, where we had ISDN in class, and I KNOW that with 11.2,
this was never a problem. I always had students both do dialer maps so they
could have the experience, but today it does not work anymore.
It seems to me that this is a new feature with 12.0, because I remember in
the "good old days" (grin) of 11.2 when it wasn't that way.

Subject: ISDN ISSUE
I am having a problem geting this senerio to work.. as configured below only
one router can initiate the call and bring up the ISDN link (R2 the one with
the dial map statment) as it should . however when i add a dial map statment
to R1 so both routers can bring up the ISDN link the following hapens:
when either router attempts to ping accross link the ISDN connection is
established(link comes up) but i am not able to ping throu from either
side(nor does ospf traffic pass)
if i remove one of the dial map statments from one of the routers (as i did
below ) r2 brings up the link and all ip traffic is passed as it should
(including ospf updates)from either direction
can someone tell me what I'm missing????
