[OpenSIPS-Users] Custom RADIUS Accounting with "AAA RADIUS MODULE"

[Bogdan-Andrei Iancu]

Hello Ewgwny,

The module docs offers some good basic examples : 
http://www.opensips.org/html/docs/modules/1.9.x/aaa_radius.html .

Before spending too much time in doing your own manual accounting with 
Radius, have you evaluated the possibility to use the ACC module (auto 
accounting) with RADIUS backend and extra accouting option 
(http://www.opensips.org/html/docs/modules/1.9.x/acc.html#id293362).
