Hello Daniel,

I’m just seeing that 4.2 is scheduled for 15th October.

I can wait until this date.

Regards,

Igor.

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.

Cheers,
