Hi Daniel,
Indeed the case with the state full replies seems not to be taken care
of. I attach a patch with the proposed solution.
Could you please provide feedback?
1. I am unsure if the place I introduced the run_onsend call is
appropriate since the buf used for msg_send is constructed
build_res_buf_from_sip_req and build_res_buf_from_sip_res calls.
2. Also, we can maybe unite these if call branches I created:
send_res = msg_send(&uas_rb->dst, buf, res_len);
send_res = SEND_PR_BUFFER( uas_rb, buf, res_len );
3. Do you think a get_send_socket snippet as follows should be inserted
before the /*if (onsend_route_enabled(SIP_REPLY)){*/ :
if(dst.send_sock == NULL) {
dst.send_sock=get_send_socket(msg, &dst.to, dst.proto);
if (dst.send_sock==0){
LM_ERR("cannot forward reply\n");
}
}
Thank you,
Lucian

Hello Lucian,
I applied your patch with some fixes.
I haven't checked with stateful replies, at some point a function from
core should be used. You can go ahead and see if it works, if not, let
me know and I can look into it as well. You can follow the callbacks
for TMCB_RESPONSE_OUT or TMCB_RESPONSE_FWDED inside tm code, they
should lead to the place where a sip response is going to be sent out.
Cheers,
Daniel

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

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:

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*

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.

Daniel
Thank you and sorry again for my late answer,
Lucian
