Sounds like you forgot to put the "name" parameter on the map statements.
Check out "show dialer" you could find that when you open a connection you
have 2 channels open. If that is the case you have 1 channel on each router
doing simplex to the other side... That's because the routers don't know
where they are connected to.

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????
