I saw that you had "isdn caller 12 callback" in the config of the called
router, as well as a callback class and dialer callback-secure. Try
removing the isdn caller 12 callback and see what happens, do a debug
callback on the called router and if it still fails see what the router
says.

~Subject: "dialer callback-secure" prevent me from calling back ! HELP
~
~
~Members,
~
~As subject says, I can`t make a callback to the callback client
~if "dialer callback-secure" configured on callback-server.
~There is no problem for callback-server to initiate a callback
~if that command is not configured.
~I know that this must be relate to dialer map ip name class
~and map-class configuration, but already spent a whole day
~trying to figure this out without success.
~Any help would be appreciate.
~
~The following are the configurations, debug results, etc:
~
~1. Network config
~Please refer to Solie`s book Lab 17.
~green-bay------FR (ISDN backup)-------san-diego
~
~green-bay is the callback-server , IOS 12.1(12a)
~san-diego is the callback-client , IOS 12.2(5)
~
~2. "debug dialer" result
~
~From green-bay console:
~
~green-bay#sd
