When you debug callback, do you see the callback negotiated? Also do a
debug dialer to see the lines come up on the calling router, and then go
down after callback is negotiated. In your map-class I believe you should
have "dialer callback-server username" instead of just the "dialer
callback-server" to make this work. Try those out and see how it goes.

Subject: ISDN Callback
Hi there...
I have a bit of problems verifying PPP Callback...
What I have is the following
R1----ISDN----R2
R1 requests callback, R2 accepts
When I do a ping from R1 to R2(Which triggers the DDR) the ping goes through
fine, and I see the Virtual bundle1 comming up twice, but when I do show
ISdn active I get the following output on R1...
ISDN-1#sh isdn active
----------------------------------------------------------------------------
----
ISDN ACTIVE CALLS
----------------------------------------------------------------------------
----
Call Calling Called Remote Seconds Seconds Seconds Charges
Type Number Number Name Used Left Idle
Units/Currency
----------------------------------------------------------------------------
----
Out 384020 ISDN-2 13 - - 0
----------------------------------------------------------------------------
----
When I do this show ISDN active should it not read call-type "in" instead of
out?
I have attached the configs here:
