Hello, I would like to know if there is any specific configuration in kamailio.conf to enable/disable handle the array of ICE candidates. In my tests, using PJSIP for the development of my User Agent, I notice that when ICE is enabled, several calls made do not reach the other User Agent and in this case they receive a 408 error. I am suspicious that Kamailio is getting lost, when the SDP arrives with the array of ICE candidates. The initial goal of using ICE is to promote peer-to-peer communication when both are under the same router, because the application is always with STUN enabled. Best regards Thiago Barcelos Guimarães thiago.barcelos(a)gmail.com

DIAMETER over SCTP for Rx and Cx Interfaces

by Ron McLeod

I would like to connect Kamailio to a PCRF (Rx interface) and HSS (Cx interface) using DIAMETER over SCTP. Is this currently supported? If it is, are there any notes on how to configure this? If not, and there are plans to develop this, I would like to get involved in testing. Thanks.

custom kamailio-x.deb package

by Abdul Basit

Hi All, I am trying to compile custom .deb package from kamailio source that will install dependencies like mysql-server, lua, rtpproxy, etc. and will install few custom scripts along with additional db tables from tables-create.sql files. I am able to create kamailio_x-amd64.deb package that I installed on fresh machine dpkg -i kamailio_x-amd64.deb This package installed kamailio config files and modules in appropriate locations but it didn't created default, init.d and kamailio.service files. Nor it asked for installing the dependencies which I mentioned in control file. OS: Debian GNU/Linux 8.9 (jessie) Kamailio: 5.0.3 through git clone I am creating .deb package for the very 1st time. Can anyone point me to the right direction? -- regards, abdul basit

How to troubleshoot "ERROR: error while initializing modules"

by ron.kamailio＠mcleodnet.com

I have built kamailio-5.0.3 from source with no issues. I have used the P-CSCF configuration examples from ./misc/examples/pcscf and the database definitions from ./utils/kamctl/mysql. When I check the configuration file, it is reported to be "ok": # /usr/local/sbin/kamailio -c loading modules under config path: /usr/local/lib64/kamailio/modules/ 0(10835) INFO: pv [pv_shv.c:60]: shvar_init_locks(): locks array size 16 0(10835) INFO: <core> [core/sctp_core.c:75]: sctp_core_check_support(): SCTP API not enabled - if you want to use it, load sctp module Listening on udp: pcscf.core.ims1.test [172.25.152.20]:4060 Aliases: *: pcscf.core.ims1.test:* config file ok, exiting... But when I attempt to run the application, it fails with an error message "ERROR: error while initializing modules": # /usr/local/sbin/kamailio -D -d loading modules under config path: /usr/local/lib64/kamailio/modules/ Listening on udp: pcscf.core.ims1.test [172.25.152.20]:4060 Aliases: *: pcscf.core.ims1.test:* WARNING: no fork mode ERROR: error while initializing modules How can I troubleshoot this to determine what the actual error is? I have tried increasing the debug level, but I don't see any additional information. Thanks.

presentce handly_subscribe() protocol/port mismatch to WS endpoint

by Yuriy Gorlichenko

Hi. I have presence server and it works fine for UDP/TCP/TLS endpoints. For now i have new one type of endpoints that runs via WebSockets It sends SUBSCRIBE request to the and then after handle_subscribe() NOTIFY not comes to the subscriber because of [core/forward.c:231]: get_send_socket2(): protocol/port mismatch I already had some issues regarding this for ACK for example but i resolved it cimply doing $ru = $ru+";transport=wss" but NOTIFY sending is internal process and can't be controlled by config file. So i can not change $ru for NOTIFY directly. Any ideas how to fix this?

Inserting local path into shared USRLOC table.

by Marrold

Hi All, I am wondering if the following is possible. For simplicity imagine two asterisk boxes and two kamailio proxies. Kamailio on the edge, asterisk in the 'core' Kamailio <=> Asterisk Asterisk <=> Kamailio A user may register to either kamailio proxy, and a call may originate from either Asterisk box where it will be sent to its *local *Kamailio proxy. >From there I'd like Kamailio to forward the request to the AoR, following the same path the registration took if it registered to the other proxy, to avoid NAT issues. I think this requires a shared USRLOC table, and also for the proxy that handled the registration to insert itself in the path of the USRLOC table. The registrar module has the 'path_check_local' parameter which sounds relevant, ignoring the path if the first hop is local. I've included add_path_received() in my REGISTRAR routing block, however I see 'Path: [not set]' in the USRLOC table. Is it possible to force the insertion of the local proxy into the path field? One additional question, in the case of NAT keepalives, is it possible to only send these from the proxy the received the register request? Thanks in advance, Matthew

kamailio QOS questions

by Lv, Victor (NSB - CN/Qingdao)

Hi All, Currently, we would like to have a try on the Kamailio QOS module toward PCRF Rx interface, it's looks a little complex to configure. Is there anyone had already successfully configured the Rx interface? If yes, could you share your configuration with me? Thanks in advance. Victor

Forcing a TCP Connection Closed?

by Mark Boyce

Hi all Just working on some connections security filters on a Kamailio install. The security goes something like this; In REQINT … if source_ip is not in customers IP white-list then just exit This works fine for UDP where packets are just ignored if they don’t come from a trusted IP. However on TCP this leads to the connection staying open until it either times out or the source disconnects. Which feels untidy. Is there a way to say close the TCP connection from within the config script? Thanks Mark -- Mark Boyce

Route Header - Comma separated issue

by Soltanici Ilie

Hi all, Why Kamailio are not removing full Route header in case if he is receiving comma separated Route? For example: Receiving such Message: SUBSCRIBE sip:101@192.168.1.1 SIP/2.0 Route: <sip:192.168.1.1;r2=on;lr=on;ftag=fb0076047b3da3e4;nat=yes>, <sip:172.16.30.10;sbc=topoh-NFlx.VXxPVXv8rfM83X1KnhF83LINVLO8VcJ6VL79zkEYH5U83hdKVhyKFi-5zX-5njs67kyYSllNx**> Event: dialog User-Agent: Cisco/SPA504G-7.6.2 Content-Length: 0 after applying loose_route function, kamailio is forwarding this message: SUBSCRIBE sip:101@192.168.1.1 SIP/2.0 Route: Event: dialog User-Agent: Cisco/SPA504G-7.6.2 Content-Length: 0 Other devices are sending 2 Route Headers in separate rows - and everything is working properly. Is this a bug or it should be like this per RFC? Thank You. using Kamailio 5.0.3.
