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

[Ewgeny]

Hi,


I use custom radius accounting with "AAA RADIUS MODULE", because I have to adapt the RADIUS accounting with complex system, and i have to send many many specific attributes to the RADIUS server.
I'm using functions "radius_send_auth", "radius_send_acct".
I didn't find good examples in google or in mailing list - about using of "AAA RADIUS MODULE".

Due to the manual RADIUS accounting there are many nuances, which does not happening when using standart RADIUS accounting module "Acc Module" with "setflag(ACC_DO)".


As you can see in my code examples - I should call Radius Acct-Stop and Radius Acct-Start in many places of opensips.cfg.
What do you think about stability and reliability about my method of RADIUS accounting ?

I have problem with Acct-STOP on loose_route(), because not always i should do it.
For example when routing in local call - i don't start accounting, and i didn't setflag(DOACCT) - but in loose_route flags are not working.
How to do STOP package sending not every time when receive SIP BYE, but only in those cases when a START packet was sent ?



I'm sorry for my poor English....
