Hello! I'm doing some testing with http requests but got stuck at the beginning. event_route[xhttp:request] does not seem to be executed. I'm getting the following in the log with the most basic configuration. Am I missing something? Jun 3 20:50:35 kamailio-dev-2 kamailio[9148]: 13(9161) DEBUG: <core> [core/ip_addr.c:577]: print_ip(): tcpconn_new: new tcp connection: 127.0.0.1 Jun 3 20:50:35 kamailio-dev-2 kamailio[9148]: 13(9161) DEBUG: <core> [core/tcp_main.c:1238]: tcpconn_new(): on port 46328, type 2, socket 23 Jun 3 20:50:35 kamailio-dev-2 kamailio[9148]: 13(9161) DEBUG: <core> [core/tcp_main.c:1630]: tcpconn_add(): hashes: 1391:1425:2615, 2 Jun 3 20:50:35 kamailio-dev-2 kamailio[9148]: 13(9161) DEBUG: <core> [core/io_wait.h:367]: io_watch_add(): processing io_watch_add(0xb22d80, 23, 2, 0x7f7a63877f30) - fd_no=17 Jun 3 20:50:35 kamailio-dev-2 kamailio[9148]: 13(9161) DEBUG: <core> [core/io_wait.h:598]: io_watch_del(): DBG: io_watch_del (0xb22d80, 23, -1, 0x0) fd_no=18 called Jun 3 20:50:35 kamailio-dev-2 kamailio[9148]: 13(9161) DEBUG: <core> [core/tcp_main.c:4671]: handle_tcpconn_ev(): sending to child, events 1 Jun 3 20:50:35 kamailio-dev-2 kamailio[9148]: 13(9161) DEBUG: <core> [core/tcp_main.c:4335]: send2child(): selected tcp worker idx:1 proc:10 pid:9158 for activity on [tcp:127.0.0.1:8089], 0x7f7a63877f30 Jun 3 20:50:35 kamailio-dev-2 kamailio[9148]: 10(9158) DEBUG: <core> [core/tcp_read.c:1782]: handle_io(): received n=8 con=0x7f7a63877f30, fd=6 Jun 3 20:50:35 kamailio-dev-2 kamailio[9148]: 10(9158) DEBUG: <core> [core/tcp_read.c:627]: tcp_read_headers(): no clen, p=A Jun 3 20:50:35 kamailio-dev-2 kamailio[9148]: 10(9158) ERROR: <core> [core/tcp_read.c:1555]: tcp_read_req(): bad request, state=7, error=4 buf: Jun 3 20:50:35 kamailio-dev-2 kamailio[9148]: GET /TEST HTTP/1.1 Jun 3 20:50:35 kamailio-dev-2 kamailio[9148]: Host: 127.0.0.1:8089 Jun 3 20:50:35 kamailio-dev-2 kamailio[9148]: User-Agent: curl/7.43.0 Jun 3 20:50:35 kamailio-dev-2 kamailio[9148]: Accept: */* Jun 3 20:50:35 kamailio-dev-2 kamailio[9148]: parsed: Jun 3 20:50:35 kamailio-dev-2 kamailio[9148]: GET /TEST HTTP/1.1 Jun 3 20:50:35 kamailio-dev-2 kamailio[9148]: Host: 127.0.0.1:8089 Jun 3 20:50:35 kamailio-dev-2 kamailio[9148]: User-Agent: curl/7.43.0 Jun 3 20:50:35 kamailio-dev-2 kamailio[9148]: Accept: */* Jun 3 20:50:35 kamailio-dev-2 kamailio[9148]: 10(9158) DEBUG: <core> [core/tcp_read.c:1562]: tcp_read_req(): received from: port 46328 Jun 3 20:50:35 kamailio-dev-2 kamailio[9148]: 10(9158) DEBUG: <core> [core/ip_addr.c:577]: print_ip(): received from: ip127.0.0.1 Jun 3 20:50:35 kamailio-dev-2 kamailio[9148]: 10(9158) DEBUG: <core> [core/tcp_read.c:1704]: release_tcpconn(): releasing con 0x7f7a63877f30, state -2, fd=6, id=2 ([127.0.0.1]:46328 -> [127.0.0.1]:8089) Jun 3 20:50:35 kamailio-dev-2 kamailio[9148]: 10(9158) DEBUG: <core> [core/tcp_read.c:1705]: release_tcpconn(): extra_data (nil) Jun 3 20:50:35 kamailio-dev-2 kamailio[9148]: 13(9161) DEBUG: <core> [core/tcp_main.c:3745]: handle_tcp_child(): reader response= 7f7a63877f30, -2 from 1 Jun 3 20:50:35 kamailio-dev-2 kamailio[9148]: 13(9161) DEBUG: <core> [core/tcp_main.c:3668]: tcp_emit_closed_event(): TCP closed event creation triggered (reason: 0) Jun 3 20:50:35 kamailio-dev-2 kamailio[9148]: 13(9161) DEBUG: <core> [core/tcp_main.c:3676]: tcp_emit_closed_event(): no callback registering for handling TCP closed event #!KAMAILIO children = 4 tcp_children = 4 debug=3 log_stderror=yes memdbg=5 memlog=5 fork=yes #!substdef "!LOCAL_UDP!udp:127.0.0.1:5060!g" #!substdef "!LOCAL_HTTP!tcp:127.0.0.1:8089!g" listen=LOCAL_UDP listen=LOCAL_HTTP loadmodule "xlog.so" loadmodule "pv.so" loadmodule "ctl.so" loadmodule "sl.so" loadmodule "xhttp.so" event_route[xhttp:request] { xhttp_reply("200", "OK", "text/html", "<html><body>OK - [$si:$sp]</body></html>"); } Thank you very much!

Kamailio Dispatcher for Docker Asterisk
by Fernando Lopes 03 Jun '25

03 Jun '25

Hello everyone, I have Kamailio running on port 5060, and I'm running Asterisk inside a Docker container. I'm trying to connect to Asterisk via port 5061. Could someone please advise what I should add to my dispatcher list? Currently, I have the dispatcher.list entry: 1 sip:10.0.0.5:5061;transport=tcp 0 Here’s the network info for my Kamailio host (eth0 interface): inet 10.0.0.4/24 brd 10.0.0.255 scope global eth0 And here are the relevant port mappings from Docker: 5038/tcp -> 0.0.0.0:5038 5060/tcp -> 0.0.0.0:5061 5060/udp -> 0.0.0.0:5061 ... My main question: Is the dispatcher entry sip:10.0.0.5:5061;transport=tcp correct if Asterisk is listening on port 5061 in the container? Do I need to adjust anything on the Kamailio side or change the dispatcher entry format? Thanks in advance for any help!

Kamailio as Proxy only
by disa_369＠msn.com 03 Jun '25

03 Jun '25

Hello to everyone. I deployed Kamailio on Debian system. Install was successfull. I have not much experience Kamailio and i dont know what need to run Kamailio as Proxy. I have the task to use Kamailio as proxy between Avaya PBX and Videoconference System. Outgoing calls only from Avaya PBX -------> Kamailio ----> Video System. We dont need Kamailio subscribers\peers, Just to forward a call from avaya to Video system by ip. Video system has IVR number 3000, all we need to dial number 3000@ip_of_video_system. I got questions. 1. Do we need install maria_db for that? 2. Do we need create subscriber\peer on Kamailio? 3. Do we need add modules for that? And main question what to add in kamailio.cfg is? Thx!!!!!!!!!

Kamailio Regex
by Timothy Delin 03 Jun '25

03 Jun '25

Hi everyone, I need your advice. I am extracting a SIP Body message from a User Agent Client using the regex as such "$var(calling_party)= $(var(body){re.subst,/.*Calling-party:\s*sip:(\+[0-9]+)@.*/\1/});" And I tried to log it as "xlog("L_INFO", "Extracted number 1: $var(calling_party) <><><>\n");" However, the output in my logs is only showing as below, where I cannot see any value after my variables. "1(6) INFO: {1 10 SUBSCRIBE 5017ae21204c72a3} <script>: Extracted number 1: +6512345678" I suspect this is the reason why when I tried to use this variable in a redis_cmd, it returns as null as the variable may have impacted the command input to Redis. I tried to change the $var(calling_party)="+6512345678" and it is working perfectly fine Best regards, Timothy
