I have the latest asterisk 1.6 and libpri installed. I am using
Digium's B410P (with the DAHDI driver).

AOC-E (units) are properly decoded. With minimal changes in chan_dahdi
you can set the units in CDR. This works only if the call leg which
receives the AOC messages hangs up first no matter where the other
call leg is coming from (sip, analog). If the other leg hangs up first
then the CDR is written before the AOC-E is received.

I do not receive AOC-D or S so I can't say if the patch works, but it
should work with some modifications. Anyway some of the logic in the
libpri patch seems to be already in the current release.
