Hi Joel,
Thank you for your response.
In fact, I want to get Request-line URI's parameters of the outgoing INVITE that is leaving the first Kamailio box, briefly. Unfortunately "du - destination URL" or "sndto(name)" pseudo-variables indicate the next hope's information. And in this case, the next hope's information is not same as the ClientB's information.
As I tried to tell before, our setup is like that:
ClientA -> Kamailio1 -> Kamailio2 -> ClientB
I need the request line URI parameters of the invite message sent by Kamailio1 to Kamailio2. And these parameters contain ClientB's ip and port information such as 10.252.180.51:36945 as you can see below:
INVITE sip:905364167881 at 10.252.180.51:36945;transport=tls SIP/2.0
Record-Route: <sip:gearbox11.turkcell.tgc:5060;r2=on;lr;did=7f5.f572;nat=yes>

CSeq: 21 INVITE
Call-ID: 1wF-vjzGIX
...
And, your question: no, we don't use the dispatcher mechanism. We just check the DB to find out Kamailio server which the number registered into and send the messages to this server basically.
Thanks for all...

Hi all,
I'm a newbie for Kamailio and working on a feature needs end-users' destination IP in the first transferred/forwarded invite message.
Basically, our system/call flow is like:
ClientA -> Kamailio1 -> Kamailio2 -> ClientB
Invite from the clientA:
tls:212.252.34.165:32980
tls:172.21.193.100:5061
INVITE sip:905364167881 at testsip.tvoip.turkcell.com.tr:443 SIP/2.0
Via: SIP/2.0/TLS 100.64.13.139:56993;branch=z9hG4bK.GoiTxA4Ee;rport
From: <sip:905368601286 at testsip.tvoip.turkcell.com.tr>;tag=WbINy0ypx
To: sip:905364167881 at testsip.tvoip.turkcell.com.tr
CSeq: 20 INVITE
...
Needed Ip (Client B's IP 10.252.180.51 for this case) is in the INVITE row of the forwarded message.
Invite to the Kamailio2 :
udp:172.21.193.100:5060
udp:172.21.193.98:5060
INVITE sip:905364167881 at 10.252.180.51:36945;transport=tls SIP/2.0
Record-Route: <sip:gearbox11.turkcell.tgc:5060;r2=on;lr;did=7f5.f572;nat=yes>

CSeq: 21 INVITE
...
When the first invite message receives, the dialog variables or sel(msg...) parsed values belong to this first received message, as far as I understand during the tests. However I need the forwarded invite message's variables. Even after t_relay in RELAY route, it looks the message I have is the first one. So, I cannot reach this later IP in the forwarded invite message. As far as I understand, bear with me here please, this IP manipulation executes in t_relay function and in the C side of Kamailio. So, I cannot find a way to do that in the our native scripts.
Is there any way to get it without diving C code's abyss? Do you have any idea about it? I would appreciate it, if I can get any help or any clue.
Thanks for all...

Rtpengine does this automatically, unless the `asymmetric` flag is used.
You should see a log message about a `confirmed peer address` as soon as the first RTP is received on a port.
Cheers

Hello,
If I understand correctly your email, you want the IP/Host of the destination of the outgoing INVITE that is leaving a Kamailio box?
First of all, how are you forwarding the request? Are you using dispatcher module?
Here are a couple of options:
1-
https://www.kamailio.org/wiki/cookbooks/5.3.x/pseudovariables#du_-_destination_uri
(although
this depends on your config, it might not be set)
2- https://www.kamailio.org/wiki/cookbooks/5.3.x/core#onsend_route + https://www.kamailio.org/wiki/cookbooks/5.3.x/pseudovariables#sndto_name
If you can describe a little more how you are doing things we might be able to give you more information.
Joel.

Hi again.
Thanks for all the help and suggestions. I realized the issue happens if using kernel forwarding only. If I change rtpengine to start at userspace without the kernel module enabled everything works fine as expected.
Do you have any hints on why this could be happening with the kernel module?
I'm running rtpengine like this:
usersapece: $ rtpengine -f -L 7 --interface=100.100.100.100 --listen-ng=
127.0.0.1:2223 --tos=184 --sip-source
kernel: $ rtpengine -f -L 7 --table=0 --interface=100.100.100.100
--listen-ng=127.0.0.1:2223 --tos=184 --no-fallback --sip-source
when using kernel module, I'm also setting this rules on chain INPUT under
iptables:
-A INPUT -p udp -m udp --dport 5000:16383 -j RTPENGINE --id 0 -A INPUT -p udp -m udp --dport 16384:32768 -j RTPENGINE --id 0 -A INPUT -p udp -m udp --dport 49152:65535 -j RTPENGINE --id 0
Looking forward to hear from you guys.

The libcurl seems to offer an option for that as well:
- https://curl.haxx.se/libcurl/c/CURLOPT_INTERFACE.html
So it can be a small patch to the module and support it in the future.
If you look for a solution on current stable, maybe one of the embedded scripting languages can help, you can execute inline a small script in Lua/Python/Perl with app_lua_run() & equivalents. In the past I used the http client from lua to do more complex http api queries (e.g., with specific headers, ...).
Cheers,
Daniel

Daniel,
Got the same issue on 5.3.1 with openssl1.1, debian9.
After 3 working days of tests (about ~30-50 wss clients), suddenly we've got
a lot of connections stucked in CLOSE_WAIT state. Kamailio called
sig_alarm_abort() when we try to reboot.
Thanks,
Andrey

Content-Type: text/plain; charset="utf-8"
Hi,
I am on kamailio 5.2.4 and want to use the xhttp module for certain management operations.
The request involves some DB queries . The DB is remote and via ODBC and might have some delay.The documentation on the xhttp module states about latency http://kamailio.org/docs/modules/devel/modules/xhttp.html mentioning that the request is handled in an asynchronous manner.
However, the JSONRPC-S module documentation says that this module implements the support for asynchronous RPC commands only for HTTP and HTTPS transports.
https://www.kamailio.org/docs/modules/devel/modules/jsonrpcs.html#idm1049416972
I am confused about the process under whose context the xttp request . Can there be a dedicated process to handle certain management requests which do some custom instructions like certain DB operations or initiate certain http requests ?
Thanks,Rupesh

Message-ID:
<CAH3xi0-AEEj_bwLYd4OzSH96Cz8=qyrdsNWTjWnf5Sm1efrvhg at mail.gmail.com>
Content-Type: text/plain; charset="utf-8"
Hi All,
I'm having some issues trying to properly send a '302 Moved Temporarily'
reply to the calling UAC (UAC1) when the remote UAC (UAC2) returns a 486
status (Do Not Disturb). The goal is to redirect UAC1 to a voicemail server
when UAC2 is in DND.
Here are the pertinent parts of my config:
route {
# drop some things right away
route(DROP);
# perform sanity check
route(SANITYCHECK);
# handle registrations
if(is_method("REGISTER")) {
route(REGISTRATION);
exit;
}
# handle invites
if(is_method("INVITE")) {
route("INVITE");
exit;
}
route(RELAY);
}
route[INVITE] {
# add this proxy to the record-route so it stays in the loop
record_route();
# if we can find this user in the location DB...
if(lookup("location")) {
# relay the invite to the new dURI
t_on_failure("FOURDIGITFAIL");
t_on_reply("FOURDIGITREPLY");
route(RELAY);
# go back to the main route
return;
}
onreply_route[FOURDIGITREPLY] {
if(t_check_status("4[0-9]{2}")) {
t_reply("302", "Moved Temporarily");
}
}
I'm having issues with the t_reply in the onreply_route. It successfully
sends the reply, but I can't seem to set the Contact header properly. I'm
trying to set it to the location of the user's mailbox on the voicemail
sever (ie sip:1000 at vmpbx.domain.com), but nothing I try works. I've tried:
remove_hf("Contact");
insert_hf("Contact: sip:1000 at vmpbx.domain.com");
t_reply("302", "Moved Temporarily");
But as I understand it, that just changes the header in the reply from
UAC2, not the reply I'm sending to UAC1
Then I tried:
append_to_reply("Contact: sip:1000 at vmpbx.domain.com" );
t_reply("302", "Moved Temporarily");
But I can't use append_to_reply in an onreply block.
How can I change the Contact header in the reply that's sent? Am I just
going about this the wrong way? Any help would be appreciated. Thanks

The kernel module receives its instructions from the userspace daemon,
so there's no reason there should be a difference. Can you post 1) logs
and 2) the flags you use for your offers/answers?

Thank you Daniel,
I implemented a work around (little proxy in go) but would love if the
option was added for the future.

Try doing this in a failure_route[]; onreply_route[] isn't really meant
to transform replies, just to passively observe or drop them.
Also, you'll want to use append_to_reply():
https://kamailio.org/docs/modules/5.3.x/modules/textops.html#textops.f.append_to_reply
Note that the conditions that give rise to the invocation of a
failure_route are broader and somewhat more abstract than any given SIP
reply -- e.g. transaction reply timeouts. So, you would want to
structure your failure_route like this:
failure_route[REDIRECT_HANDLE] {
if(t_is_canceled())
exit;
if(t_branch_timeout()) {
# Handle the timeout case...
exit;
}
# Use $T_rpl to access reply code ($rs) and reply reason if needed
# ($rs), per:
#
# https://www.kamailio.org/wiki/cookbooks/5.3.x/pseudovariables#t_rpl_pv
if($T_rpl($rs) == 486) {
append_to_reply("Contact: <sip:...>\r\n");
t_reply("302", "Moved Temporarily");
exit;
}
# Some other case.
}
