I believe I have run into an IOS bug problem.
I have tested the regular calls, i.e. "ping ipx 14.6.6.6" from R1 or "ping ipx
14.1.1.1 from R6" both bring up the ISDN connection.
Originally I was running c2500-jos56i-l.121-5.t9 on both routers, and the clie
nt first makes the call, but it does not drop the call to wait for callback and
the ISDN line stays up for 2 minutes.
Then I use c2500-js56i-l.121-12 on both routers, this time the client made the
call and drop it to wait for callback, but the server did not try to call the c
lient back. The ISDN connection never got re-established.
Then I use c2500-js-l.112-21 on the client side and c2500-js56i-l.121-12 on the
server side, this time the client made the call, drop it, make the call again,
drop it, made it again, drop it again... (5 times, since I was sending a regul
ar ipx ping of 5 packets). And finally gave up.
Then I use c2500-js-l.112-21 on both routers, the behavior is the same as it i
s under the oringinal IOS.
Last I use c2500-js-l.121-2 on both routers, the behavior is the same as it is
under the oringinal IOS.
Just a reminder, I am tsting IPX connection and a dialer-class is configured on
the server side.
map-class dialer dial1
dialer callback-server username
Have you experience this before ? What is the IOS version on which you can mak
e it to work ?
Thank you.

Make sure you have this config on R6:
map-class dialer dial1
dialer callback-server username
Also, in my own test setup I have seen different versions of 12.x work and
not work with the exact same configuration on the router - the only
difference being the firmware version load on the router. I would recommend
experimenting with different firmware versions if your sure the
configuration is correct.

Subject: ISDN PPP Callback
Hi,
I have configured two BRIs to do callback, but the client makes the call,
and brings up the line, but it never drops the call and force a callback.
I thought i am doing everything per the DOC.
TIA.
