Hi Liran,
the problem u are facing it is a well known issue of FreeRADIUS. SQL
module is missing the Accounting-Type=15, so nothing related to
OpenSER, therefore nothing to be fixed here.
A sollution would be using the patch provided with the distribution of
CDRTool, or directly get it from their site:

(link name "Freeradius patch for OpenSER accounting").
Hope it helps,
DanB
