I got ISDN caller ID callback to work in my home lab. Its actually an
easier config than the ppp callback and costs less. Since ppp callback
requires that the callback server connect the call and do negotiation you
still incur toll charges although they would be small. Caller ID callback
simply recognizes the calling party number in the inbound setup. If this
number matches one configured on the router than it will not connect the
call and initiate a call to the callback client. In my configuration, I was
able to get it to work with just one command in addition to the standard
ISDN setup (Legacy DDR) with dialer maps.
isdn caller [remote number] callback
debug isdn q931 will let you see the call setup. There are other commands
that you may need to tweek.
this url is good for the information and is directly from the documentation
cd. You should get very familiar with this cd.

Hope this information helps.
