i'm using 3.2 branch of the git repository.

I'm under the impression that my idea behind this implementation is
somewhat flawed.

The idea was to  count calls per "domain".  If the the idea is
reflected in my approach then
i will head for minor tweaking. But if my implementation is just plain
wrong, then i will have to
do it manually, like using sqlops and do the dialog accounting myself.

cheers.
