Hello Daniel,

I must admit I only saw your mail last Friday. Until the 10th of October I was also on vacation. I know that you actually committed some of the changes together with your comments on the 12th this month.

I don't know if we can consider the topic of the patch closed. As far as I understand, the state-full replies have not been addressed, right? (There should be a change in the t_reply.c) I followed the code to the relay_reply but I did not yet come to find the send function. Should I pursue further?

Thank you,
Lucian Balaceanu

Hi Lucian,

somehow I forgot to follow up on this. But we need to get sorted out soon, before we release, so it works as expected with the new version. See more comments inline.

Hi Daniel,

Please forgive me for my delay in responding to your mail.
Please find attached a second version of the onsend_route_reply patch (which again has some problems). As per your previous indications I did the following:

Issue1

From performances point of view, there can be added a config parameter to enable running of onsend_route for replies:

onsend_route_reply = 0|1

Following http://www.asipto.com/pub/kamailio-devel-guide/#c08add_parameters I have tried to add onsend_route_reply parameter. The code compiles, but when trying to start kamailio with this parameter inside, the parsing fails with syntax errors signaling:

0(1321) :<core> [cfg.y:3423]: yyerror_at(): parse error in config file kamailio-basic.cfg.4.1, from line 107, column 1 to line 108, column 0: syntax error
0(1321) : <core> [cfg.y:3423]: yyerror_at(): parse error in config file kamailio-basic.cfg.4.1, from line 107, column 1 to line 108, column 0:
ERROR: bad config file (2 errors)

The issue is:
+<INITIAL>{ONSEND_RT_REPLY}	{  yylval.intval=atoi(yytext);
+						yy_number_str=yytext; return NUMBER; }

It should be:

+<INITIAL>{ONSEND_RT_REPLY}	{  yylval.intval=atoi(yytext);
+						yy_number_str=yytext; return ONSEND_RT_REPLY; }
Issue2

#define onsend_enabled(rtype) (onsend_rt.rlist[DEFAULT_RT]?((rtype==SIP_REPLY)?onsend_route_reply:1):0)

That is to say you see it best to take the chek for onsend_rt.list[DEFAULT_RT] from inside run_onsend() function and call this onsend_enabled(...) before the run_onsend()?

This is to detect whether the onsend_route should be executed for SIP replies. The condition being:

- if is a sip reply and onsend_route is set and the onsend_route_reply parameter is 1

Issue3

On the other hand, is onsend_route also executed for local requests? I had in mind it is only for received requests that are forwarded ... Iirc, on onsend_route, the sip message is the one received, the outgoing content being accessible via $snd(buf).

I agree with you with taking out the locally generated requests and only left the run_onsend call in do_forward_reply function (inside forward.c).
Could you point me to the reply relaying function that is called for state-full processing?

Stateful processing for replies is mainly done in t_reply.c from tm module. At some point there should be a send buffer function call.

Cheers,
Daniel

Thank you and sorry again for my late answer,
Lucian
