I believe with the digium codec you can do asterisk -rx 'show g729' and
get data back that tells you how many are in use and how many are
available.  You could write a script that will look and send a report,
however there are problems with this:

1. it cuases higher system load to run this often
2. calls can be bursty, a bunch of short lived calls can consume all
your licenses, and your script didnt run in time and you didnt know
until its too late.

The real fix would be to hook into the SDP negotiation for sip (and
whatever codec negotiations are used for any other protocols you use) to
check if g729 loaded, if so check avialable licenses, if enough are
available then allow that coded, otherwise dont list it as available.
If that is done this becomes less of an issue since you wont have dead
calls and warnings spewed to the screen.
