Hello,
Thank you ! Not sure to have the time for testing it before 4.2.
Will it be ported to 4.2 or are you waiting for my feedback?
Regards,
Igor.

Hello,
you can browse the git repository online and get from there the patch or diff:
- http://git.sip-router.org/cgi-bin/gitweb.cgi?p=kamailio;a=history;f=modules/acc;hb=HEAD
Or on github:
- https://github.com/kamailio/kamailio/commits/master/modules/acc
Cheers,
Daniel

Hello Daniel,
I don’t use the GIT repository. I still use the source from tar.gz.
Can you give me the link to the patch? I will patch acc module and compile it.
Regards,
Igor.

Hello,
I pushed a fix to kamailio master branch that should solve it -- last commits to acc module. If you can give it a try and report results, would be appreciated.
Cheers,
Daniel

Hello Daniel,
I’m just seeing that 4.2 is scheduled for 15th October.
I can wait until this date.

Hello,
Thank you for your time on this issue.
I understand that I can define “db_extra” like:
modparam("acc", "db_extra",
"src_user=$fU;username=$Au;src_domain=$fd;src_ip=$si;src_pai=$avp(s:pai);"
"dst_ouser=$tU;dst_user=$rU;dst_domain=$rd")
Instead of:
modparam("acc", "db_extra",
"src_user=$fU;username=$Au;src_domain=$fd;src_ip=$si;src_pai=$ai;"
"dst_ouser=$tU;dst_user=$rU;dst_domain=$rd")
And, in the request_route
request_route {
#Store PAI in AVP for accounting
$avp(s:pai)=$ai;
# per request initial checks
route(REQINIT);
[…]
}
I can put this fix while waiting for 4.2.
Regards,
Igor.

Hello,
not really troubleshooting, as I got traveling, but I thought a bit of it, also from performances point of view.
As it was related to parallel processing of 1xx/2xx sip responses that you are accounting, I think the safest solutions would be:
- clone the message locally to acc if it is the tm (share memory)
- do synchronized access to tm data inside the acc (use locks there)
Instead of using locks or other workarounds in tm (lower performances in all cases), better do it on the part doing parallel access out of tm. Acc is doing some particular processing -- it uses a callback for a reply to access the response, so it is quite specific to it.
If you want to be safe side immediately, store the PAI in an avp inside request_route and use that avp for accounting.
A solution will be there before 4.2 is out.
Cheers,
Daniel

Hello,
so it is still related to PAI header -- I will have more time to look at it by end of the week.
