[Serusers] only INVITE accounted

[Rosario Pingaro]

I configured ser to work with an pstn gw accounting all call to mysql db.

But I when I call a local user I get accounted the INVITE and the BYE 
messages, but when I call an outging uri I get accounted only BYE 
messages and not the INVTE.

Where is the probelm?
THANKS
below there is may ser.cfg file:
