Hello guys, after changing instance type from t2 to t3a for kamailio server
in aws log(/var/log/kamailio.log) file and some other files are corrupted
and I can not touch,delete,create or anything and when kamailio start
receiving traffic it crashed.
Is there any particular reason for this? Basically on t2, they are under
/dev/sda1 and /dev/xvda. Under t3 they are nvme disks (biggest part of the
speed increase), so they are under /dev/nvme1n1.
Note: once I rollback to t2 everything is working as expected.
Hello,
I am trying to configure kamailio to use external antifraud protection using so called "traffic loop" when call is forwarded to external SIP proxy that would response even with same INVITE back or with error message if number is fraud.
schema: PBX -> kamailio -> traffic loop -> kamailio -> carrier
Kamailio in second and fourth step is the same.
Issue is that if kamailio receives same INVITE back to I would like to forward to next carrier it is possible, but kamailio struggles with transaction handling.
If ACK message come from PBX, kamailio will correctly forward it to traffic loop but when it comes back, function t_check_trans is failed and I cant relay it. Only workaround is to use send() message, but that causes deny of BYE message from carrier.
My question is following:
Is it possible to register two different transactions states for same message? If yes how? If no, would it help to send and receive messages on another network port or not?
Thank you,
Michal
Hello!
Due to I still experience irregular Kamailio 5.4 crashes (like 1/month)
related to SSL (using websockets and SIPS) I'm wondering, could openSSL
upgrade change the situation?
As of now in CentOS 7 I have 1.0.2k version.
Does anyone have experience to fix crash-related to TLS problems with
openSSL upgrade?
Or maye some tuneup of TCP parameters can help here?My current setup is
quite simple:
children=4
enable_tls=yes
tcp_accept_no_cl=yes
tcp_connection_lifetime=600
tcp_max_connections=998976 # 1000000 - 1024, so we're leaving 1k for system
reserve
tls_max_connections=998976
Number of clients ~ 200 constantly connected to websocket.

HI,
I am facing a problem related to the IMC module.
I have installed kamailio 5.2.x and I tried to list the members of a
room-qsipchat.
In my test environment the kamailio.cfg file it is very basic, the
kamailio server listen on
tcp=192.168.100.192:15006
the client run on a PC with IP address 192.168.100.156
the imc outbound_proxy is set
modparam("imc", "db_url", DBURL)
modparam("imc", "imc_cmd_start_char", "#")
modparam("imc", "outbound_proxy",
"sip:sip-test.quintetto.it:15006;transport=tcp")
The client start by sending a #join message to kamailio and looking the
log file I can see that the room-qsipchat has been create, and also I
received the message 200 OK.
By using the tcpdump I can see the join message from the Client to
kamailio server and the reply from kamailio to the client.
When I send the #list message to the room-qsipchat , I expecting to
receive the message relate to room's members and the 200 OK message.
When I tcp dumping I saw the following messages

Hi sr-users,
Since ClueCon is going on right now, and some Kamailio community members
are involved I hope you will forgive a little promo here: I have a RHEL8
build of the just released 1.10.8 on Copr:
https://copr.fedorainfracloud.org/coprs/beaveryoga/FreeSWITCH-1.10.8/
Hope you will find it useful in your kamailio + Class 5 scenarios!
Cheers

Hello,
as I am not a user of dialog variables, I am turning to community to ask
for help testing the current master branch with configurations that make
use of dialog variables and acc dialog-based cdr generation.
With a few reports of issues related to dialog modules and unexpected
crashes, I looked over the code and noticed that the access of the value
for dialog variables was not protected, making them vulnerable of
invalid memory access in case of the variable was updated by another
process or dialog was terminated.
I introduced a couple of new functions to try to cover different use
cases of getting the dlg variable values, dialog management code was not
affected, but given that these commits need to be backported to stable
branch (5.6), I want to get proper feedback from community that things
work fine.
A previous attempt of a simpler fix was not enough, having side effects
to acc module for dialog-based cdr generation, because it was keeping
referenced to many dlg variables at the same time.
In short, it would be appreciated any feedback on testing dialog and acc
with dialog-based cdr generation using git master branch.
Cheers,
Daniel

Hi
Looking for advise if anyone could point out where im going wrong.
My setup is Kamailio Ver 5.6.0 running in azure , rtpengine Version: git-master-dc395d5, behind kamailio I have asterisk ver 18.12.1
Kamailio conf I have interface set as below
listen=udp:10.3.1.6:5060 advertise WANIP:5060
and rtpengine.conf set as below
interface = eth0/10.3.1.5
but when I can make a call I don't get any audio, rtpengine.log extract below shows that rtp is going to the private IP rather that the Public IP of the phone that initiated the call, do I need to set rtpengine_manage() to fix this?
Oct 7 09:38:58 kamailio-proxy rtpengine[8127]: INFO: [NmE0MjdhMzA4NjUzYWVjMmRjYzIxNGJjMTY4ZTc2MWE. port 30278]: [core] Confirmed peer address as 10.3.1.5:12890

Since on the topic of tsilo:
1. I watched Federico’s presentation on it from 2015, and his examples insinuate that it is necessary to store the index and label of a suspended transaction in some external vehicle, e.g. htable, for use with ts_append_to(). Why would one do this when it is possible to call ts_append() based on R-URI alone?
2. The appropriate pattern of interaction between tsilo and http_async_client — which I imagine to be a rather common use-case — is rather unclear.
If I use http_async_query() to call out to a PN service, with $http_req(suspend) = 1, what should happen to the current instance of SIP request processing?
That is to say:
request_route {
. . .
t_check_trans();
if(is_method(“REGISTER”)) {
. . .
save(“location”, “0x06”);
if(ts_append(“location”, “$tu”)) {
xlog(“success”);
}
return;
}
else if(is_method(“INVITE”)) {
# PN stuff.
ts_store(“$var(uri)”);
http_async_query(“http://url”, “PUSH_REPLY”);
return; # <— ???
}
}
route[HTTP_PUSH_REPLY] {
. . .
if(!t_relay())
sl_reply_error();
}
I should add that this proxy front-ends a registrar, but is not in itself a registrar. It contains a shadow registrar - hence the save() calls - in order to be able to take advantage of the ’tsilo’ module, given its dependency on registrar/usrloc.
This leads to the difference that the gateway receives requests with RURIs that have already been resolved to a contact binding elsewhere, so there are no lookup() calls. How should this play into the http_async_client workflow?
Appreciate any help!

Hi,
When there are no stored transactions for an AOR, it logs this error:
Oct 13 07:48:18 gw1 /usr/sbin/kamailio[14758]: ERROR: tsilo [ts_append.c:64]: ts_append(): failed to retrieve record for sip:abalashov@sip.evaristesys.com
But not having transactions ts_store()’d is a rather normal occurrence, right? It is the expected case the vast majority of the time that someone registers.
Does that mean one is simply destined to have this scary-looking error, to the syslog ERROR facility, for a normal runtime condition? Is there not some principle against using attention-grabbing error messages this way? Would a patch to fix be welcome?

Hi Sir/Mada,
I'm trying to integrate kamailio + freeswitch, according to the manual http://kb.asipto.com/freeswitch:kamailio-3.3.x-freeswitch-1.2.x-sbc on Kamailio v5.6
modified the kamailio.cfg file, add WITH_FREESWITCH parts, then kamailio could NOT start up.
Could you please help check, what should be modified to fit the version 5.6？
Thanks！
