It would not be very hard to create a CALLEDTON variable. The information 
is sent from libpri to chan_zap. A few more fields in chan_zap and a 
little bit of code in pbx.c.

I really _ really_ wish asterisk would stop using the pseudo-variables and 
simply store stuff in the dialplan variables (like PRI_CAUSE etc already 
do). These pseudo-variables are stupid since in most cases reading and 
writing them is not time critical.

We use cvs from an old date (predating these functions) but with quite a 
few additional patches of our own. there is currenctly a showstopper bug 
where the dtmf-detecting dsp is disabled on outbound call legs. Bad if you 
need #-transfers.
