[SR-Users] [sr-dev] Missing accounting events in ACC table

I did a basic test (acc with parameters as in default kamailio.cfg) and
invite is accounted ok. I used master branch, but there is no difference
with acc from 4.2.

Can you run with debug=3 and see all the log messages, maybe you get a
further hint from there.

Also, you can try with clone_msg parameter set to 0 - it is one of
latest additions to acc module, just be sure you don't have some corner
case situation...

Cheers,
Daniel
