Crash on REGISTER
by Igor Potjevlesch 03 Apr '14

03 Apr '14

Hello, I experienced an issue yesterday. I move a customer to Kamailio 4.0.4 (previously he was on an old SER instance without issue). He uses the same SIP account for connecting two IPBX (same platform, same firmware). When the second REGISTER came on Kamailio and, may be 500ms/1s after (I have sufficient time to see 200 OK (2 bindings) on Wireshark), Kamailio crash with coredump generated. I know that I must analyse the coredump but I hope that could be a known issue. In addition, when I try to run "gdb" on the core files, I got the following: Core was generated by `/usr/local/sbin/kamailio -P /var/run/kamailio.pid -m 256 -M 64'. Program terminated with signal 11, Segmentation fault. #0 0x00000030f2230f30 in escape_string_for_mysql () from /usr/lib64/mysql/libmysqlclient.so.16 Missing separate debuginfos, use: debuginfo-install glibc-2.12-1.80.el6.x86_64 keyutils-libs-1.4-4.el6.x86_64 krb5-libs-1.9-33.el6.x86_64 libcom_err-1.41.12-12.el6.x86_64 libconfuse-2.6-2.el6.rf.x86_64 libselinux-2.0.94-5.3.el6.x86_64 mysql-libs-5.1.61-4.el6.x86_64 nss-softokn-freebl-3.12.9-11.el6.x86_64 openssl-1.0.0-20.el6_2.5.x86_64 zlib-1.2.3-27.el6.x86_64 I guess that I'm missing packages to troubleshoot. Many thanks. Regards, Igor.

NAT Traversal issue
by Wingsravi R 03 Apr '14

03 Apr '14

Dear Kamailio'ns, I am working on Kamailio server (V 4.1.2) with RTPproxy (1.2.1) integrated, in a standalone intranet infrastructure (no any connection with internet). I dont have any NAT settings in my network set-up. even though i will not get Audio/video calls through some times. So in that concern I have installed RTPproxy, now all the audio/Video calls are fine (with some Pixelled). I have the Following Kamailio configuration script, in which it suppose to invoke RTPproxy service when the SIP clients behind NAT. But every time when i do Audio/Video calls, they are proxying through RTPproxy server only. I analysed SIP captures of Audio/video call, i didnt found any IP/port changes in the whole SIP session and with this i assumed that there is no NAT issue in my Network. But why all the Audio/Video calls are proxying through RTPproxy everytime ? Is there any Wrong placement of function call in Kamailio configuration script (below) ? #----------------------------------------------------------------- #!ifdef WITH_NAT # ----- rtpproxy params ----- modparam("rtpproxy", "rtpproxy_sock", "udp:127.0.0.1:7722") # ----- nathelper params ----- modparam("nathelper", "natping_interval", 30) modparam("nathelper", "ping_nated_only", 1) modparam("nathelper", "sipping_bflag", 7) modparam("nathelper", "sipping_from", "sip:pinger@192.168.2.52") modparam("nathelper", "sipping_method", "INFO") # ----- NAT_traversal ----- modparam("nat_traversal", "keepalive_interval", 60) modparam("nat_traversal", "keepalive_method", "NOTIFY") modparam("nat_traversal", "keepalive_state_file", "/var/run/kamailio/keepalive_state") # ----- params needed for NAT traversal in other modules ----- modparam("nathelper|registrar", "received_avp", "$avp(RECEIVED)") modparam("usrloc", "nat_bflag", 6) #!endif #Routing Script # ----------------------------------------------------------------- # Sanity Check Section # ----------------------------------------------------------------- route { if (!mf_process_maxfwd_header("10")) { sl_send_reply("483","Too Many Hops"); break; }; #if (msg:len > max_len) { if (msg:len >= 8192 ) { sl_send_reply("513", "Message too big"); break; }; # ----------------------------------------------------------------- # Record Route Section # ----------------------------------------------------------------- #if (method!="REGISTER") { if (!method=="REGISTER") { record_route(); }; if (method=="BYE" || method=="CANCEL") { # unforce_rtp_proxy(); rtpproxy_answer(); } # ----------------------------------------------------------------- # Loose Route Section # ----------------------------------------------------------------- if (loose_route()) { if ((method=="INVITE" || method=="REFER") && !has_totag()) { sl_send_reply("403", "Forbidden"); break; }; if (method=="INVITE") { if (!proxy_authorize("192.168.2.52","subscriber")) { # proxy_challenge("","0"); proxy_challenge("192.168.2.52", "0"); # break; } else if (!check_from()) { sl_send_reply("403", "Use From=ID"); break; }; consume_credentials(); if (nat_uac_test("19")) { setflag(6); force_rport(); fix_nated_contact(); }; rtpproxy_offer("l"); }; route(1); break; }; # ----------------------------------------------------------------- # Call Type Processing Section # ----------------------------------------------------------------- # if (uri!=myself) { if (!uri==myself) { route(4); route(1); break; }; if (method=="ACK") { route(1); break; } if (method=="CANCEL") { route(1); break; } else if (method=="INVITE") { route(3); break; } else if (method=="REGISTER") { route(2); break; }; lookup("aliases"); if (uri!=myself) { route(4); route(1); break; }; if (!lookup("location")) { sl_send_reply("404", "User Not Found"); break; }; route(1); } # ----------------------------------------------------------------- # Default Message Handler # ----------------------------------------------------------------- route[1] { t_on_reply("1"); if (!t_relay()) { if (method=="INVITE" && isflagset(6)) { rtpproxy_answer();; }; sl_reply_error(); }; } # ----------------------------------------------------------------- # REGISTER Message Handler # ----------------------------------------------------------------- route[2] { if (!search("^Contact:[ ]*\*") && nat_uac_test("19")) { setflag(6); fix_nated_register(); force_rport(); }; sl_send_reply("100", "Trying"); if (!www_authorize("192.168.2.52","subscriber")) { www_challenge("192.168.2.52","0"); break; }; if (!check_to()) { sl_send_reply("401", "Unauthorized"); break; }; consume_credentials(); if (!save("location")) { sl_reply_error(); }; } # ----------------------------------------------------------------- # INVITE Message Handler # ----------------------------------------------------------------- route[3] { if (!proxy_authorize("192.168.2.52","subscriber")) { proxy_challenge("192.168.2.52","0"); break; } else if (!check_from()) { sl_send_reply("403", "Use From=ID"); break; }; consume_credentials(); if (nat_uac_test("19")) { setflag(6); } lookup("aliases"); if (uri!=myself) { route(4); route(1); break; }; if (!lookup("location")) { sl_send_reply("404", "User Not Found"); break; }; route(4); route(1); } # ----------------------------------------------------------------- # NAT Traversal Section # ----------------------------------------------------------------- route[4] { if (isflagset(6)) { force_rport(); fix_nated_contact(); # force_rtp_proxy(); rtpproxy_offer(); } } onreply_route[1] { if (isflagset(6) && status=~"(180)|(183)|2[0-9][0-9]") { if (!search("^Content-Length:[ ]*0")) { # force_rtp_proxy(); rtpproxy_offer(); }; }; if (nat_uac_test("1")) { fix_nated_contact(); }; } Please find the Attachment for Tcpdump based Video call Sip capture for your better Understanding. PS: Both Kamailio and RTPproxy are running on same IP (host), i.e 192.168.2.52. Please anybody help me in resolving this issue. Any help will greatly appreciate. Regards, Ravi.

when dialing another extension, instead of ringing for 30 sec, vmail kicks in right away
by mark li 03 Apr '14

03 Apr '14

I'm using kamailio as a sip proxy and registrar, and freeswitch for all media services like vmail, conference calls, ivrs etc. I just set up vmail ... and it seems to be working. Except that it appears that I've broken something else because now when I call extB from extA, instead of ringing first for a little while and then having the vmail kick in afterwards, vmail kicks in right away. someone mentioned that it could be a forking problem. I'm afraid I don't really understand what this means. just wondering if you can point me in the right direction list, as far as what I should be looking for in the kamailio.cfg file... Thanks.

I'm trying to google to see if I can find the article the made references to similar error messages. But in the meantime, I thought I'd check the list to see if you could point me in the right direction.

Understunding the routing logic with WebSockets
by DURECU, OLIVIER (OLIVIER) 02 Apr '14

02 Apr '14

Hi experts, Using websockets, I am facing a behavior I can't manage explaining : on reception of an initial REGISTER (over websocket), it seems that the routing logic in the request_route method is not invoked Extract of my Kamailio.cfg to explain =================================================================== Request_route { xlog("L_DBG", "Entering request_route for $rm") ... Onreply_route[REGISTER_reply] { If (t_check_status("200")) xlog("L_DBG", "REGISTER OK") Event_route[xhttp:request] { xlog("L_DBG", "XHTTP Request received") ws_handle_hanshake(); In my logs, I only see > XHTTP Request received > REGISTER OK No trace of "Entering request route for REGISTER" ! whereas for a subsequent INVITE, I see the trace Any explanation ? because of this, the fix_nated_register() is not called, and I suspect this causes the troubles I meet trying to make call with websockets Olivier DURECU Bell Labs / IP Platform Research Villarceaux Center Tel: +33(0) 130772759 GSM: +33(0) 683776482

Hello, Probably i dont see the dialog variable in the onreply route , because I see on the trace ip that sometime on the reInvite the proxy dont put on the record route the dialog cookie. On the first invite , its ok , but on every reinvite (we have sip session timer) there isnt. Its correct ? Thanks Da: pars3c [mailto:pars3c@gmail.com] Inviato: martedì 1 aprile 2014 17:32 A: 'Kamailio (SER) - Users Mailing List' Oggetto: Reply route and variable Hi , i have a question for all : in the onreply_route is visible a dialog variable ($dlg_var(ring_time)) or a avp variable ? Can I set them , on this kind of route ? On the event route (dialog start) they are all null. I try to set them, but some time (on reInvite) this variables are not setted. Why? Thanks to all

Dimension a kamailio server
by Rizwan Khan 02 Apr '14

02 Apr '14

HI Guys, can you refer me to some resources which help me dimension the hardware for a setup. Total users will be 20,000. What percentage should i assume for concurrent audio and video calls? What is the standard practice? How does this all map to the cpu, ram and storage etc. given that I will be storing the cdrs as well. In the futute this setup should be scalable so that it should support 200,000+ users within a span of 6-8 months. What would be the ideal architecture? Thanks, Rizwan Khan

webrtc (websockets) to UDP and vice versa
by ik 01 Apr '14

01 Apr '14

Hello, I'm a newbie with Kamailio, and I require to connect webrtc (websockets) based phones, into a VoIP PBX that does not support websockets. I wish to create/use Kamailio rules that will translate UDP to websockets and vice versa. I have found few examples over the internet, but as it seems (to me), they are just doing normal SIP operations under websockets (registration, routing, voicemails etc). Is there a way to make Kamailio a broker that understand both transports, and translate them ? If so, can you please point me to a documentation/example that does it that might help me better understand it ? Please note that I do not have any experience with Kamailio, and just getting started with it. Thank you very much, Ido

Notify registered users of primary server status change
by Neven Boric 01 Apr '14

01 Apr '14

Hi, I'm using kamailio as an intermediate proxy with survivability. That means I'm monitoring the primary server using the dispatch module, and if it goes down, I take control of all further requests. The main server acts as registrar, but I keep a copy a of the registered users list. There's a feature of Siemens (now Unify) phones and SBC where in this same scenario, the SBC will send a NOTIFY packet informing the status change to the phones. The phones then display a message indicating "limited service" and re-register. To indicate that they support this feature, phones send a "Supported: X-Siemens-Proxy-State" header when registering. The NOTIFY packet from the SBC includes the header "Event: server-mode-backup" or "Event: server-mode-normal" according to the main server status. I would like to replicate this functionality in kamailio. I looked at the presence module, as it already sends NOTIFY requests, but UACs have to subscribe to events first, and Siemens phones do not. I am trying to do it manually in the event_route[dispatcher:dst-down/up] triggers, but I can't find a way to iterate through all registered users. I would appreciate some assistance: - Is there some module I'm missing that implements something similar? - If not, how to iterate through all registered users to manually send a request to each of them? - If I send the requests using uac_req_send, will they be sent sequentially from the same thread? Thanks Neven Boric

IMS and SIP over WebSocket 500/Error
by DURECU, OLIVIER (OLIVIER) 01 Apr '14

01 Apr '14

Hello all, I have installed Kamailio 4.1.2 in IMS configuration (3 Kamailio instances to run in P/I/S-CSCF modes) Everything works fine with Native IMS clients (Boghe) I want now to introduce Web clients using WebSockets. I have added to the P-CSCF Kamailio.cfg the websockets parts Registration is Ok but I can't manage placing a call. With SIPoWS, the contact header is sip:olivier@132.invalid. So when the P-CSCF receives a terminating INVITE, its destination URI is sip:olivier@132.invalid , it tries to make a DNS resolution of 312.invalid and it doesn't forward to the client saying the domain is unknown and can't be routed I guess that something is missing in my configuration around aliases/nathelper/outbound but didn't find what... Thanks for any help Olivier DURECU Bell Labs / IP Platform Research Villarceaux Center Tel: +33(0) 130772759 GSM: +33(0) 683776482

Intermittent Audio/video call
by Wingsravi R 01 Apr '14

01 Apr '14

Dear All, I am working on Kamailio server (V 4.1.2) with RTPproxy (1.2.1) integrated, in a standalone intranet infrastructure (no any connection with internet). I have a strange behavior with my set-up here is : --> Audio/Video calls are just go fine with only kamailio server (Without running RTPproxy instance). But with the same script and set-up sometimes i'm experiencing one-way audio/video !!. What could be the reason for this behavior ? Is it a NAT problem ? How can i solve this issue ? --> I was just suspecting it as NAT problem and installed RTPproxy server, with this all the audio/video calls are going fine. But i'm curious to know about this intermittent audio/video calls that too without any changes to Kamailio configuration and my set-up. Please below find the attachment for kamailio config file. Please anybody help me in resolving this issue. Any help will greatly appreciate. Regards, Ravi

Social Configuration module for Kamailio released
by Alex Balashov 01 Apr '14

01 Apr '14

For immediate release: ATLANTA, GA (1 April 2014)--Evariste Systems LLC, an Atlanta-based consultancy and software vendor specialising in Kamailio-based VoIP infrastructure solutions for the ITSP (Internet Telephony Service Provider) market, has announced the public release of its groundbreaking "Social Configuration" module for the Kamailio open-source SIP server and SIP proxy. Evariste principal Alex Balashov explained: "It's no secret that writing Kamailio configuration in its embedded scripting language is complex. Social Configuration integrates with Twitter and Facebook to allow tens of thousands of people to write a config simultaneously through social networks, over a variety of devices and media, including PCs, tablets, smartphones and SMS. This lets Kamailio users harness the benefits of crowdsourcing." Continued Balashov: "The process begins when the Kamailio administrator writes the desired intentions of their setup--yes, in natural English prose. This isn't for propellerheads. The module sends this to our proprietary QNLP (quantum natural language parsing) server, which splits these desiderata into Business Action Items (BAIs). These are then sent out to participating Facebook and Twitter users via our expansive middleware, and the users return their piecemeal script implementations, which are usually one line of code or less. These are consolidated back into a fully functional Kamailio configuration." Brooks Bridges, Director of Engineering at Evariste, explained how Social Configuration handles reconciliation of conflicting implementations from across the Twittersphere and Facebook: "This is really the heart of the technology. It's handled via a deeply recursive, Rails-based social A/B testing and multiple-choice polling system. It uses hashtags, trending and RSS and stuff. The days of merge conflicts with unified diffs are gone! Throw out your legacy version control, 'cause this is Conflict Resolution 2.0: The Feed!" Another frequently asked question lingered: assembling the contributions in a particular order. On this topic, Balashov offered a surprising answer: "Plot twist: that's social, too! Twitter is an infinitely dynamic collaboration platform. The question isn't so much 'what can social networks do for us?' as 'what can't they do?' You can see that there are many strata of social clouds here: cumulus, stratus, cirrus--we've got all the clouds!" "Xzibit would make it easier to understand for the layman," chortled Balashov as he shifted his position slightly. "The whole process uses infinitely differential recursion manifolds. It's like: 'Yo dawg, I heard you like crowds, so we put a crowd in your crowd, so you can crowd while you crowd', you know? All stages of the process happen simultaneously and in real time. It's consensus-driven development by a Committee of the Ultimate." Balashov also stated that total development time for Social Configuration was only three days, rather than the thousands of man-hours normally required to develop complex technology. When asked how this was possible, he deferred to Bridges: Bridges explained: "It's all because we embraced the Agile Full Vapour method at our company. Maybe you've heard of it. Classic Agile and 'customer-driven development' says 'release early, fail often'. That wasn't enough for us. Agile Full Vapour is Agile extended to its logical maximum. Our slogan here at Evariste Engineering is 'Release Too Early, Fail More Often'. And stand-ups? Ain't nobody got time for that. We've done away with all team communication or collaboration of any kind. We've slashed overhead to a new level, and the numbers speak for themselves. We get three thousand percent more out of our developers than anyone, anywhere else." Balashov concurred, gesturing to the Evariste office "Vapour Board": "I really don't know how legacy Agile companies get anything done!" Initial reactions to the new technology from inside the VoIP community were positive. Sean McCord, Vice President of Wholesale Hashtag and viral marketing expert at Atlanta-based social media anaytics giant CyCORE Systems, agreed that Social Configuration is an essential leap forward for the Kamailio ecosystem: "The Social Configuration module heralds the long-overdue marriage of Kamailio with the Social Web, the biggest trend of the Internet in this millenium so far, and probably for the rest of the millenium. Everyone knows that the wisdom of crowds is greater than the wisdom of one." On the broader theme of Kamailio's ascendancy to the mainstream of the Social Web, McCord said: "Anyway, the whole reason Kamailio hasn't gone viral so far is due to lack of network effects. We have planking, owling, Grumpy Cat, so why not Kamailio? Kamailio's imagery is green like Philosoraptor. What's stopping it from going big like Philosoraptor? No network effects, no multiplier--that is, until now." J.R. Richardson, Chief Technology Officer of Dallas-based Ntegrated Solutions, reported positive results from his initial testing: "Down here in Texas, we're a real social bunch. But I always felt so lonely writing Kamailio script by myself. I don't even know what I'm doing half the time. But now, with this Social Configuration business, the whole neighborhood can help out!" John Knight, Chief Engineer at Ringfree Communications in Hendersonville, North Carolina, also spoke highly of the new social technology: "It's great! The config just writes itself! But the best part for me, as a civically conscious businessman, is the economic boost. It's a much better employment opportunity for stay-at-home moms in Appalachia than Mechanical Turk. I'm paying out 2 cents per core function call, 4 cents per modparam, 10 cents per Record-Route parameter, and 5 cents per module function invocation. Stimulate this economy!" Carlos Alvarez, an international business consultant at The Himley Dock Table Agency, a Phoenix, Arizona-area think tank focused on sociology of the World Wide Web, was keen to note that the technology brought forth by Evariste was far more than just a different way of implementing Kamailio solutions. "We were talking with Evariste about building an XMPP server and selling it to Facebook for $20 billion, but that train left the station. It was a blessing in disguise, though, because it told us that we weren't thinking big enough. Social Configuration is way more transformative." Asked further about what it meant, Alvarez said: "This is going to have implications way beyond esoteric programming. A crowdsourced config is nothing like an individual's config; it's e-cosmopolitanism, it's Humanity 2.0. It will open up the floor to new kinds of first movers and lead to new assumptions about how scripts of all kinds should be written. It's going to challenge established notions of what it means to program, and it will make the playing field more level by disintermediating the supply chain of session initiation. A lot of middlemen are going to hurt. One does not simply program the program anymore; the program programs you, too. It programs all of us. For the first time, request routes and SRV load balancing are part of a living, breathing organism. And that's worth way more than an XMPP server. That's disruption right there." After a moment's thought, Alvarez added: "I can probably flip it to Facebook for at least $3 trillion in Zuckerberg funny money--whoops, did I say that? I meant Facebook stock." The transformative impact forecasted by Alvarez is seemingly borne out in the enthusiasm for Social Configuration shown around the world by a variety of societal constituencies not traditionally thought to be associated with software development and telecommunications. Jakub Klausa, a self-described member of an "anarcho-syndicalist reading group" in Wroclaw, Poland, confidently offered a hypothesis about the` new era brought forth by Social Configuration: "Let's start with the deeply-ingrained assumption of Kamailio consultant or trainer as 'teacher', as a purveyor of knowledge that he has and you don't," said Klausa. "That's a very oppressive, authoritarian construction. It's quite presumptuous and dehumanising. Oh, does the Kamailio 'expert', His Royal Highness, deign to 'teach' us, to 'share' what he knows with the little people? Oh, thank you, massa', thank you!" lamented Klausa. "You see, it's not so much about what the consultants and self-anointed mailing list demigods can 'teach' us. It's more about what we can all learn from each other! Social Configuration is a tool that finally allows us, the workers, the so-called 'newbies', to take the power of Kamailio into our hands and master our own destiny. It's time to put a knife through the tyranny of 'expertise' and 'knowledge'." The Chairman of the Plenary Session of the Central Committee of the Revolutionary Communist Party of Poland, Magdalena Boksa, issued the following communiqué from the party's headquarters, thought to be located in an underground bunker beneath a Starbucks: Social Configuration empowers the revolutionary vanguard of the activated, class-conscious proletariat to commandeer the machinery of Kamailio, in order to advance a scientific understanding of the objective laws of motion of the capitalist system, together with the tension of its internal contradictions, in keeping with the essential truth of dialectical materialism. The global imperialist division of labour, as revealed by V.I. Lenin in Selected Works, Vol. 1, shall meet its end through the thunderous destruction of the petit-bourgeois monopoly on knowledge-as-capital and the extraction of surplus value from it. Through the dogma of Social Configuration, the means of production in Information Technology shall be socialised among the working class, distributed according to the principle of "from each according to his ability, to each according to his need". When asked about the revolutionary potential of Social Configuration, a young student member of the RCP-Poland Youth Brigade concurred with Comrade Boksa's recitation: "¡Venceremos! ¡No pasarán! ¡Hasta la victoria siempre!" The impact of Social Configuration has even played out on a national, and perhaps global level of significance. A brief statement from the Ministry of Foreign Affairs of the Democratic People's Republic of Korea read: Social Configuration of Red Star SER [as it is known inside North Korea] is consistent with the teachings of Kim Il-Sungism and Kim Jong-Ilism. Great Leader Kim Jong-Un, Supreme Commander of the Korean People's Army, First Secretary of the Workers' Party of Korea, will chart the glorious course to the maximum realisation of its full military and civil potential in all spheres of public and private life. It will boost the resilience of our prosperous socialist nation in the face of a continual onslaught by the imperialist menace and its ROK puppet regime. Motivated by chronic energy shortages, the secretive North Korean state has been rumoured to be working on a Kamailio-based personal VoIP appliance that is--the first of its kind--powered not by conventional electricity, but by The Juche Idea. Social Configuration has also garnered attention from scholars attentive to the role of gender, race and privilege in the configuration scripting process. Moriah Trostler, a resident feminist scholar at the Phoenix, Arizona-based Scorpion Bay Institute of Gender Studies, gave some insight into the ways that Social Configuration potentially broadens the inclusiveness of the Kamailio tapestry: "If people would check their cisprivilege and open their eyes, they would see that Kamailio, and SIP itself, is full of oppressive, psychologically violent gendered constructions. For instance, there is the infamous 'loose routing vs. strict routing' dichotomy, which is clearly a dark, sadomasochistic allegory for capricious--dare I say schizophrenic?--sexual humiliation. It's a lurid invitation to indulge the prurient whims of the boss-with-secretary." Trostler gave another example: "And From and To 'tags'? Please, the idea of ownership of another's corporeal being, of branding--tagging--like cattle, is transparent. That's straight out of the Larry Flint smut-peddling playbook. And what's more, all this makes use of 'globally unique identifiers', the signature scent of industrial alienation--an anonymising, dystopian, Kafkaesque labyrinth. This has all the markers of masculinised depersonalisation. Need I go on?" Trostler went on: "Social Configuration opens the door to speaking truth to some of these discriminatory, alienating, gendered mental categories in which brogrammers think. Finally, women can write the Kamailio config as they might have written it, without compromising their identity or their dignity. Maybe we can even make some headway in influencing the male-dominated IETF standards process." Asked to summarise the impact of emergent minority voices and critical discourse enabled by Social Configuration, Fred Posner, a literary theorist based in Gainesville, Florida, offered the following comments: "The larger power of Social Configuration is essentially meta. It offers a new language, a new word-prism through which to look at the neosemiotic discursive space of SIP express routing. It's about reader as text, and text as reader, and the joy and wonder of their sizzling interplay." "It is evocative of Nietzsche," said Posner, gesturing to an open manhole cover on a busy Jacksonville thoroughfare. "If you stare too long into the Kamailio configuration, it, in turn, stares back into you! But now it speaks with a palpable collective voice, giving shape--definition!--to a bold, muscular subtext of configuration as culture, and culture as configuration. It is a semantic fusion of coder as critic, and critic as coder. Without knowing it--and it was inconceivable that they could have known it--Evariste has set into motion a wondrous, intricate and mesmerising ballet, a shower of sparks, a thrifty, yet spirited rejoinder to the supposed futility of poststructuralist rationalism. As we speak, a new 'Social Text' is being written!" Alistair Cunningham, a physicist from the University of Cambridge, provided an appraisal from a different angle: "Social Configuration, as interpreted by Balashov, embodies the kind of nonlinear thinking that is noticeably missing in software. At first glance, it does seem to invite a deafening cacophany, an undifferentiated chaos. But if one phase-shifts it slightly, the shadows of mathematical signatures emerge, waiting to be unlocked. The quantum resonance of social entropy doing its work gives us valuable clues into the origins of the universe at the sub-particle level."

I realise this is a little left field, but has anyone compiled kamailio to run on Android ? ( and rtpproxy etc if you know ) would be really handy if there was some experience here. -- Sincerely Jay

rls, rls_get_by_service_uri(): match not found
by Mihai Marin 31 Mar '14

31 Mar '14

Hello Sirs, I'm trying from some days to make RLS work but without success. I checked every character from kamailio.cfg, xml files from xcap but I can't find the problem and I'm out of ideas. My problem is the the subscribe is not done => 0 notifications with status. I think the key error is that: DEBUG: rls [subscribe.c:125]: rls_get_by_service_uri(): match not found, service-uri = [sip:bob@93.187.138.214] 2(29025) DEBUG: rls [subscribe.c:125]: rls_get_by_service_uri(): match not found, service-uri = [sip:bob@93.187.138.214] 2(29025) DEBUG: rls [subscribe.c:125]: rls_get_by_service_uri(): match not found, service-uri = [sip:bob@93.187.138.214] 2(29025) DEBUG: rls [subscribe.c:279]: rls_get_service_list(): service uri sip:alice@93.187.138.214 not found in rl document for user sip:bob@93.187.138.214 Request: SUBSCRIBE sip:bob-list@93.187.138.214 SIP/2.0 Via: SIP/2.0/WS kvvj9i9uhvbp.invalid;branch=z9hG4bK4622972 Max-Forwards: 69 To: <sip:bob-list@93.187.138.214> From: "Bob Test" <sip:bob@93.187.138.214>;tag=e9144sdk2v Call-ID: 52k3b9gheoj6gk2vmjlrr0 CSeq: 81 SUBSCRIBE Expires: 300 Event: presence Contact: <sip:v8jmlmeu@kvvj9i9uhvbp.invalid;transport=ws>;reg-id=1;+sip.instance="<urn:uuid:152abb8b-085d-4ca5-b658-4ecb38d1b79f>";expires=60000 Supported: eventlist Accept: multipart/related, application/pidf+xml, application/rlmi+xml, application/rpid+xml Allow-Events: refer, presence, presence.winfo, xcap-diff, conference Require: recipient-list-subscribe Allow: INVITE, ACK, CANCEL, BYE, MESSAGE, OPTIONS, NOTIFY, PRACK, UPDATE, REFER User-Agent: JsSIP 0.3.7 Content-Length: 0 Receive: NOTIFY sip:v8jmlmeu@188.215.94.132:25702;transport=ws SIP/2.0 Via: SIP/2.0/WS 93.187.138.214:5040;branch=z9hG4bKf43b.cc179644000000000000000000000000.0 To: <sip:bob@93.187.138.214>;tag=e9144sdk2v From: < sip:bob-list@93.187.138.214>;tag=67d32ce551425daaac3772fa02abe99f-daa0 CSeq: 1 NOTIFY Call-ID: 52k3b9gheoj6gk2vmjlrr0 Content-Length: 394 User-Agent: kamailio (4.2.0-dev3 (x86_64/linux)) Max-Forwards: 70 Event: presence Contact: <sip:rls@93.187.138.214> Subscription-State: active;expires=300 Require: eventlist Content-Type: multipart/related;type="application/rlmi+xml";start="<1396291389.sip:bob-list@93.187.138.214.834374984>";boundary="TnOoxHgwMlltoGjpMlgd1kNc" --TnOoxHgwMlltoGjpMlgd1kNc Content-Transfer-Encoding: binary Content-ID: <1396291389.sip:bob-list@93.187.138.214.834374984> Content-Type: application/rlmi+xml;charset="UTF-8" <?xml version="1.0"?> <list uri=" sip:bob-list@93.187.138.214" xmlns="urn:ietf:params:xml:ns:rlmi" version="1" fullState="true"> <resource uri="sip:alice@93.187.138.214"/> </list> --TnOoxHgwMlltoGjpMlgd1kNc-- I have 2 users: bob & alice.

Kamailio ICSCF strange forking
by DURECU, OLIVIER (OLIVIER) 31 Mar '14

31 Mar '14

Hi all, I have deployed an IMS based on Kamailio 4.1.2 and I don't manage establishing a call. Users registration is OK but when I initiate the call from A(a)ims.net to B(a)ims.net, I notice a strange I-CSCF behavior The INVITE message goes OK from P-CSCF to S-CSCF then to I-CSCF. Till this point everything is fine... Then the I-CSCF performs its LIR diameter request and gets an Ok response from the HSS with a S-CSCF URI The I-CSCF forwards the INVITE at the received S-CSCF. BUT at the same time the I-CSCF generates a DNS request to resolve ims.net SIP SRV (it gets itself as answer...) and forwards a second INVITE (exact copy from the one sent to the S-CSCF) to itself So I have 2 copies of the same INVITE dialog travelling in the network and messing everything. Any idea of the cause of this behavior . Thanks for your support... Olivier

SIP - WebRTC gateway
by Zappasodi Daniele 31 Mar '14

31 Mar '14

Hello, I'm figuring out the best approach to deploy a bridge between Websocket\Webrtc and SIP\rtp. Can Kamailio (+mediaproxy-ng or something else) operate as a full Webrtc\SIP gateway (signaling, audio or video transcoding, ICE and so on)? Some months ago I found the architecture described here http://www.kamailio.org/wiki/devel/rtcweb_breaker that proposes to introduce a new RTCWeb Breaker. Is it just a proposal or is Kamailio moving following this approach? If Kamailio really requires a RTCWeb Breaker, what are the main issues against using Doubango webrtc2sip with Kamailio? Performance? Interoperability? License? ...

ERROR reply code Failure route
by pars3c 31 Mar '14

Hello, i receive many error on the failure route like this " t_should_relay_response(): ERROR: t_should_relay_response: status rewrite by UAS: stored: 500, received: 487" . Do you know why ? My version of Kamailio is the 4.1.2 and the code is this: failure_route[MANAGE_FAILURE] { if (t_is_canceled()) { exit; } revert_uri(); if (!cr_next_domain("$avp(s:carrier)", "$avp(s:domain)", "$rU", "$avp(s:host)", "$T_reply_code", "$avp(s:domain)")) { exit; } if (!cr_route("$avp(s:carrier)", "$avp(s:domain)", "$rU", "$rU", "call_id")) { exit; } $avp(s:host)= $rd; t_on_failure("MANAGE_FAILURE"); t_on_branch("MANAGE_BRANCH"); append_branch(); if (!t_relay()) { exit; } } Thanks to all

Forward copy of Register information to FreeSWITCH
by Alexandr Usov 31 Mar '14

31 Mar '14

I am already have some practice to integrate Kamailio with Asterisk, when all users creates and registers in Kamailio, and calls go to/from Asterisk with static "host=kamailio_ip" settings for each user on Asterisk side. I can't (don't know - how to) use in same way integration with FreeSWITCH. Can't create in FS directory structure a user with "host=kamailio_ip", FS require registration. Maybe I can register user on Kamailio and send additional registration request to FS with src ip changed to kamailio (lan ip)? P.S. Reading FreeSWITCH 1.2 book in progress...

Patch to support symmetric UDP socket in mi_datagram
by Muhammad Shahzad 31 Mar '14

31 Mar '14

Hi, After wasting most of the day trying to make mi_datagram over UDP socket work. I eventually realize that it does asymmetric UDP communication, which creates a lot of trouble for writing a useful MI script using PERL or Python etc. Anyhow, i go through the module code and was able to write a patch for symmetric UDP communication using mi_datagram. I have tested the patch using both Kamailio 4.1 and trunk branches and it seems to compile and run flawlessly. I am attaching here with this patch for Kamailio community. It would be great if Kamailio developers would review and commit this patch to source trunk. Thank you.

dialog expire, acc
by Kelvin Chua 28 Mar '14

28 Mar '14

I have a situation here, when a dialog expires, it sends a BYE to both call legs and this does not generate an entry on acc table. however, when i use acc_db_request() on event_route[tm:local-request], i get 2 entries on acc, 1 for the downstream, and 1 for the upstream. is there a way of handling this so i can only get 1 BYE on acc?

Kamailio custom header stored in acc db_extra
by Ryan Brindley 28 Mar '14

28 Mar '14

Hey community, I'm trying to get a 2nd leg custom header value stored in my acc table. Right now I'm appending the header with append_hf in a failure route and trying to use: modparam("acc","db_extra","custom=$hdr(Custom)") A sip trace shows the header was properly added and xlog output shows the proper $hdr(Custom) value just after I append the header, but the value doesn't show in acc. Does acc only read from the INVITE of the incoming leg? Any suggestions on how to get this 2nd leg INVITE header in acc is greatly appreciated. Thanks in advance, Ryan

Trying to dial 4000 into freeswitch's vmail system - Kam Proxy returning Status 403: Not allowed
by mark li 28 Mar '14

28 Mar '14

Hi there. I'm still trying to integrate Kamailio and freeswitch... where kamailio acts as a proxy and registrar ... and freeswitch provides conference calls and voicemail. I have calls between two polycoms working and conference calls work. But when I try to leave a voice message for a user by dialing 44+ext, the sip proxy never replies to the polycom. I did a tcpdump and i can see the INVITE from the polycom to the sip proxy multiple times... but no response back. The phone eventually disconnects itself. Here's what my config looks like: http://pastebin.com/wWgyVcxc Just do a search for "route[FSDISPATCH]". You will see how I check for the "44" prefix, and then send the call to a route called "FSVBOX". Any suggestions would be appreciated. 1. route[FSVBOX] { 2. if(!($rU=~"^1[0-9][0-9]+$")) 3. return; 4. prefix("vb-"); 5. route(FSRELAY); 6. } 7. 8. # Send to FreeSWITCH 9. route[FSRELAY] { 10. $du = "sip:" + $sel(cfg_get.freeswitch.bindip) + ":" 11. + $sel(cfg_get.freeswitch.bindport); 12. route(RELAY); 13. exit; 14. } 15.

rport

I have a Kamailio server forwarding REGISTERs to an Asterisk box, similar to the way Daniel shows here: http://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb Can I force Kamailio to append rport=5060 to the topmost Via header, prior to forwarding the REGISTER to Asterisk? I tried add_local_rport() but it only included 'rport' and not 5060. Thanks, Marc

Integrating Kamailio and Freeswitch

Hi there. I'm a noobie to Kamailio and Freeswitch... but I'm trying to follow the article located here: http://kb.asipto.com/freeswitch:kamailio-3.1.x-freeswitch-1.0.6d-sbc I've tried to add all the sections marked with WITH_FREESWITCH in the sample config in the article into my own kamailio-advanced.cfg file. Here's what my cfg file looks like: http://pastebin.com/KsvrYVN7 I've restarted kamailio after making these changes. Then I tried to dial 41 to listen to vmail or 44999 to leave a message for user 999 but both return a busy tone. Any suggestions would be appreciated. Thanks.

Need to confirm the changes for the Kamailio.cfg
by varun pratapsingh 27 Mar '14

27 Mar '14

HI All, This is my first post to this community and I am new user of the Kmailio. I want to use the Kamailio and RTPProxy on the same machine. I have installed and rtpproxy succesfully and I have started both the kamailio and RtpProxy. My RtpProxy is listening on localhost:7722 port of my local machine. Now this machine is on the public IP and I want that all sip and RTP passes though this machine from SIP Softphones before going to the SIp Server. This means the machine on which I am running the Kamailio and RTPProxy will act like a SIP proxy from my SIP Softphones through which the SIP and RTP relays. SIP is relaying fine with defult kamailio.cfg but can anyone let me know the changes in Kamailio.cfg so that my RTP also passes or rleays through this Kamailio + RTPProxy machine. Thanks in advance. Thanks and Regards Varun

Rewrite SIP INVITE
by Mickael MONSIEUR 26 Mar '14

26 Mar '14

Hello, I installed kamailio and asterisk with the tutorial of asipto. For alias numbers I configured the module alias_db. Everything works because Asterisk outgoing call is directed at Kamailio, then Kamailio is sending to the alias registered (table location) Only the number alias appears in the "To" (02XXXXXX) and not in the INVITE URI. It only shows "s" ... is it possible to force writing 02XXXXXX instead of "s" ? Example: INVITE sip:s@10.1.0.191:5060 SIP/2.0 Max-Forwards: 69 From: "0475XXXXXX" <sip:1053212@sip.domain.com>;tag=as7df9ab18 To: <sip:02XXXXXX@kamailioIP:5060> Contact: <sip:1053212@asteriskIP:5060> Call-ID: 344d42bd16975a54141d11f635bdfc71(a)sip.domain.com CSeq: 102 INVITE Date: Wed, 26 Mar 2014 15:06:01 GMT Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY, INFO, PUBLISH Supported: replaces, timer Content-Type: application/sdp Content-Length: 252 Because without it, Asterisk servers behind Kamailio not will route the call to the correct extension but to the "s". Asterisk ignores the "To" apparently this is strange ... Thank you, Mickael

Using Kamailio with a SIP Trunk
by Rizwan Khan 26 Mar '14

26 Mar '14

I want the following setup: 1 Kamailio server to handle internal calls (A/V), IM and Presence. 1 Asterisk or any other way to communicate with an NGN where I will create the SIP Trunk to route calls outside of the network. Is this the right approach or there is a way to directly communicate with the NGN to make a SIP trunk by using some external modules. Any guidelines will be highly appreciated. Rizwan Khan

Memory leak when using db_unixodbc, help tracking it down (try 2)
by Alex Villacís Lasso 26 Mar '14

26 Mar '14

I have a CentOS 6 installation with the following packages installed from the RPM build service from Kamailio: kamailio-unixodbc-4.1.2-1.1.x86_64 kamailio-4.1.2-1.1.x86_64 kamailio-presence-4.1.2-1.1.x86_64 kamailio-utils-4.1.2-1.1.x86_64 I am also using db_unixodbc for all database accesses (with MySQL backend). The problem is that after a few hours, a single Kamailio process (never more than one) starts complaining that it has run out of memory: 9(11479) ERROR: uac [uac_reg.c:638]: uac_reg_tm_callback(): got sip response 408 while registering [admin_pbx.elastix.com] 9(11479) ERROR: db_unixodbc [dbase.c:335]: db_unixodbc_fetch_result(): no memory left 9(11479) ERROR: <core> [db_query.c:502]: db_fetch_next(): unable to fetch next rows 9(11479) ERROR: db_unixodbc [dbase.c:224]: db_unixodbc_free_result(): invalid parameter value 9(11479) ERROR: db_unixodbc [dbase.c:327]: db_unixodbc_fetch_result(): no private memory left 9(11479) ERROR: <core> [db_query.c:434]: db_fetch_query_internal(): unable to fetch the db result 9(11479) ERROR: presence [publish.c:108]: msg_presentity_clean(): failed to query database for expired messages 9(11479) ERROR: db_unixodbc [dbase.c:327]: db_unixodbc_fetch_result(): no private memory left 9(11479) ERROR: <core> [db_query.c:434]: db_fetch_query_internal(): unable to fetch the db result 9(11479) ERROR: presence [publish.c:108]: msg_presentity_clean(): failed to query database for expired messages 9(11479) ERROR: db_unixodbc [dbase.c:327]: db_unixodbc_fetch_result(): no private memory left 9(11479) ERROR: <core> [db_query.c:434]: db_fetch_query_internal(): unable to fetch the db result I have attached the stderr output when I kill the offending process.

Regarding SRV lookup
by Swetha Raj 26 Mar '14

26 Mar '14

Hi All, I am trying to communicate between two sip servers.The communication from external sip server user to kamailio user works but message from kamailio to external sip user is not reaching. I get the following error in Jitsi "The above message could not be delivered A network problem occurred. Please check your network configuration and try again. Error was: 408 Request Timeout" Does kamailio do SRV lookup ? How do i force kamailio to use DNS SRV lookup. Any clues ??

group regex db reload?
by Pete Ashdown 26 Mar '14

26 Mar '14

I'm using the group module to assign groups to users. As the documentation states, "the table content is loaded into memory at startup and all regular expressions are compiled". Having to restart Kamailio is cumbersome every time the table is updated. Is there a method to reload the table via kamcmd? Also, I had no luck in getting the non-regex method of group to recognize a table entry, for example, 159(a)mydomain.com was split into 159 and mydomain.com, yet it get_user_group wouldn't match it. It was only when I started using the regex table that I had success.

Unable to make calls after integration with Freeswitch
by mark li 25 Mar '14

25 Mar '14

Hi there. I had a working Kamailio proxy working where i could call from one polycom test phone to another. But then I tried to integrate freeswitch with it... (following the article found at: http://kb.asipto.com/freeswitch:kamailio-3.1.x-freeswitch-1.0.6d-sbc as a baseline. ) Now when I dial a phone, it's just silent for a few seconds... after which i get a busy tone. I did a tcpdump and have been reviewing the file in wireshark. It looks like my two test phones are registered properly... but as you can see, the INVITE is not getting an OK back. It just keeps on retrying the invite. I'm not sure how to go about troubleshooting this. Any suggestions on where to start would be appreciated. In the meantime, I'm googling around to see if I can find anything that might help me figure this out. thanks.

Re: [SR-Users] Module TOPOH: Does not unmask CALL-ID on request BYE in one direction
by Samuel F. 21 Mar '14

21 Mar '14

Hey, No, that is totally correct. What is strange is that it doesn’t trigger on the BYE coming back where direction is (should be) = 1. It never unmasks it when it goes back upstream. I will run a scenario in our setup again on Monday and send you the output. Have a nice weekend! // Samuel

Memory leak when using db_unixodbc, help tracking it down
by Alex Villacís Lasso 21 Mar '14

21 Mar '14

I have a CentOS 6 installation with the following packages installed from the RPM build service from Kamailio: kamailio-unixodbc-4.1.2-1.1.x86_64 kamailio-4.1.2-1.1.x86_64 kamailio-presence-4.1.2-1.1.x86_64 kamailio-utils-4.1.2-1.1.x86_64 I am also using db_unixodbc for all database accesses (with MySQL backend). The problem is that after a few hours, a single Kamailio process (never more than one) starts complaining that it has run out of memory: 9(11479) ERROR: uac [uac_reg.c:638]: uac_reg_tm_callback(): got sip response 408 while registering [admin_pbx.elastix.com] 9(11479) ERROR: db_unixodbc [dbase.c:335]: db_unixodbc_fetch_result(): no memory left 9(11479) ERROR: <core> [db_query.c:502]: db_fetch_next(): unable to fetch next rows 9(11479) ERROR: db_unixodbc [dbase.c:224]: db_unixodbc_free_result(): invalid parameter value 9(11479) ERROR: db_unixodbc [dbase.c:327]: db_unixodbc_fetch_result(): no private memory left 9(11479) ERROR: <core> [db_query.c:434]: db_fetch_query_internal(): unable to fetch the db result 9(11479) ERROR: presence [publish.c:108]: msg_presentity_clean(): failed to query database for expired messages 9(11479) ERROR: db_unixodbc [dbase.c:327]: db_unixodbc_fetch_result(): no private memory left 9(11479) ERROR: <core> [db_query.c:434]: db_fetch_query_internal(): unable to fetch the db result 9(11479) ERROR: presence [publish.c:108]: msg_presentity_clean(): failed to query database for expired messages 9(11479) ERROR: db_unixodbc [dbase.c:327]: db_unixodbc_fetch_result(): no private memory left 9(11479) ERROR: <core> [db_query.c:434]: db_fetch_query_internal(): unable to fetch the db result I have attached the stderr output when I kill the offending process.

Contract support engineer in Americas wanted
by Alistair Cunningham 21 Mar '14

21 Mar '14

Integrics would like to hire a contract support engineer to provide level two support to Enswitch customers. This is a contract, work at home role. It entails: * 10 to 20 hours per week (with the possibility of more in future) answering support questions. This is primarily via web ticketing system, though occasional calls with customers may be required. Questions are submitted by customers' engineers, so are generally highly technical. Many involve substantial investigation, debugging, reading of SIP traces, etc. You will not be dealing with end users or the general public. * Being on call for emergency support up to around 50% of the time. This will normally be daytime in North America as we have staff in other countries to cover night, but may occasionally be night time if necessary. You will be compensated for any callouts. * Optionally, some Perl development. If you're not interested in this, or lack the necessary skills, that's no problem. The following are hard requirements. Please do not reply unless you fulfil all of these: * Strong skills in Linux (Redhat and Debian based distributions), Asterisk, and SIP. * Moderate or better skills in Perl, MySQL, and networking. * At least a basic familiarity with Kamailio and/or OpenSIPS. * Experience of providing technical support to IT professionals. * Strong communication and diplomacy skills. * Be physically located in the Americas. Most of the customers you will be supporting are in the USA and Canada, and expect support during business hours. Please do not reply if located outside the Americas. * Be able to speak and write English fluently, and with a professional demeanour, spelling, and grammar. If you're interested in this role and meet the above requirements, please email me off-list. Please include details of your skills and experience, and a rough indication of hourly rates and availability. -- Alistair Cunningham +1 888 468 3111 +44 20 799 39 799 http://integrics.com/

Interdomain Routing
by Owais ul Haq 20 Mar '14

20 Mar '14

Hello, I have kamailio implemdented on two machines in my local network. Both are using the same database implemented on a third machine in the same network. As my servers are on local domain so given fake domain names. How can calls be routed between the two domains ?? I asked this question and got reply to use "t_relay ". I read about it but it is for stateful processing of SIP messages. I cant relate my problem to this t_relay module. What can be the solution for this ? Regards.

Child process exited by a signal 11
by Allen Zhang 19 Mar '14

19 Mar '14

Hi, Scenario: Our kamailio server normally has a debug level of 2. The server gets a segmentation fault and dies when we run a certain demo. The error message is: "[4097]: ALERT: <core> [main.c:789]: child process 4098 exited by a signal 11" And we got a lot of these before it dies: "error reading: Connection reset by peer (104)" "ERROR: tcp_read_req: error reading" Because of the low debug level, I have no idea of what child process 4098 was doing before it died. Here is the wired bit: The problem goes away if I set debug level to 5. But always occurs at debug level 2. Two questions: 1, I noticed that the main thread was 4097 and 4098 died. what is the child process created straight after main? My guess is this 4098 child process manages TCP connections. Is this correct? 2, Why does debugging level has an impact on this? Is it because higher debugging level introduces some delay? Regards, Allen

Legacy Cisco 7945 and 7960 Handset Integration with Kamailio
by Jonathan Hunter 19 Mar '14

19 Mar '14

Hi Guys, Hope your all well? Apologies for the post, however I wondered if anyone had successfully integrated Cisco 7945/7960 handsets running SIP firmware with Kamailio? I appreciate these handsets have some issues, whereby they expect responses on port 5060, even though they initiate transactions from a dynamic port, I just wondered if anyone had a working model or some pointers they could share? As we are pondering a VPN connection to remove NAT, however Id like to consider other alternatives before then. Many thanks Jon

Does tls/wss actually work or What is required for tls/wss
by jaflong jaflong 19 Mar '14

19 Mar '14

Hi, What are the requirements for connecting with tls/wss. I have not come across any information or example for this. My config is working when the client uses ws. However if I change this to use wss, (this is it only paramter I change) it does not work. I understand Kamailio does not support DTLS, I set the jssip client DtlsSrtpKeyAgreement to false to disable this, I also set the tls option to not require or verify certicficates and it still does not work. What if other considaerstion do I need to check? thanks

Hi to all, I could hardly make kamailio log cdr to db but it just logs successful calls.I need cdr of unsuccessful calls also.I used to use asterisk so in cdr I need duration and billsec separately.As far as I understand kamailio can give only one of them.Is there a way to get them? Here is my acc configuration: #!ifdef WITH_ACCDB modparam("acc", "cdr_enable", 1) modparam("acc", "early_media", 0) modparam("acc", "report_ack", 1) modparam("acc", "report_cancels", 1) modparam("acc", "detect_direction", 0) modparam("acc", "db_url", "mysql://root: secret@localhost/mydb") modparam("acc", "log_flag", FLT_ACC) modparam("acc", "db_missed_flag", FLT_ACCMISSED) modparam("acc", "db_table_missed_calls", "missed_calls") modparam("acc", "db_flag", 1) modparam("acc", "db_missed_flag", 3) modparam("acc", "db_extra","src_user=$fU;src_domain=$fd;src_ip=$si;dst_user=$rU;dst_domain=$rd") #!endif What should I exactly do?Can someone help?

Ugrade Kamailio 4.0.2 to 4.1.2
by Helena Garcia-Nieto 19 Mar '14

19 Mar '14

Hi! I am not used to manage the software upgrade and I would like to have a more detailed explanation… I've searched in the web and in the mailing list but I need a more step-by-step explanation for newbie that what I found. I downloaded the kamailio version 4.0.1 some time ago (http://www.kamailio.org/pub/kamailio/latest/src/) when it was latest release. I untar it on /opt/kamailio-4.0.2 and did make FLAVOUR=kamailio include_modules="db_mysql " cfg, Make all and make install. Now I would like to upgrade to the 4.1.2 version but I am not sure how. When you say: " just replace the binaries." What do you mean? Should I delete the /opt/kamailio-4.0.2 folder and untar the (http://www.kamailio.org/pub/kamailio/latest/src/) on a new /opt/kamailio-4.1.2 and make again? Should I remove anything else? I have modified the config file, and the kamctlrc to use mysql as dbengine. Then after making it should I execute the sql script for adapting the db? And then connecting it by modifying the config file? I am sorry if that seems a really silly question but I'd appreciate a really step by step guide help!

Re: [SR-Users] [Kamailio-Users] [Kamalito-Users] Sip MESSAGE
by Peter Reid 19 Mar '14

19 Mar '14

Hi Alex, Please let me make a comment here in support of Abdul Hakeem's comment in respect of Kamailio supporting a SIP to SMPP translation module and in furtherance of this thread (conversation). I believe Kamailio, as an open source community would glean the benefit of supporting a feature that could see better funded players use Kamailio, with SIP to SMPP, as an alternative strategy to supporting proprietary solutions. As networks look towards 4G technology the support of such a feature could see Kamailio used as a gateway between the origination technology and the legacy SMSC gateway. This is a solution, I believe, many will need to consider looking forward.

Redirect, maddr, and domain
by Marc Soda 18 Mar '14

18 Mar '14

I'm trying to handle a redirect with get_redirects(). It seems that Kamailio is ignoring the maddr param on the contact header. Is there a way to force maddr to be used? The Contact header on the 302 looks like this: <sip:2404441112@domain.com:5060 ;maddr=1.1.1.1>;q=0.5,<sip:2404441112@comain.com:5060;maddr=2.2.2.2>;q=0.25 The message is then being sent to domain.com, rather than 1.1.1.1.

Hi There, A fast solution would be to re-run the installation procedure. To do so , follow the steps below : a)Remove siremis-4.0.0/siremis/install.lock b)While reinstalling and setting up the database properties , check all of the options available at the bottom of the form . That worked for me , Cheers

Endpoint registration tracking and reporting
by Nick Raper 17 Mar '14

17 Mar '14

Hi all, What is the best way to monitor endpoint registrations? When one of our clients has a link failure or for some reason they lose their SIP registration with Kamailio, we'd like to be able to see this so that we can respond and get the trunk re-registered. We do monitor the physical links but endpoints, (usually Asterisk based), often don't re-register after connectivity is restored. I was thinking of a script that dumps the 'location' table every 10 minutes and compares it to the previous 'location' table dump and reports on the changes. Is there a better way of doing this?

Softphone cant connect
by aawaise 17 Mar '14

17 Mar '14

Hello, I have deployed a kamailio server. Now I am trying to set up a voip call between two soft phones (EyeBeam) located on local network. I am using "Outbound proxy option" on softphone. It shows "peer to peer mode enabled". Settings are shown in figure attached <http://sip-router.1086192.n5.nabble.com/file/n125931/1.jpg> But when I make a call. It doesnot connect. Using wireshark on kamailio server, I found that in response to "SIP : Request" packet, it sends ICMP packet "Destination Unreachable: Port Unreachable". Firewall is disabled on all concerned systems. What can be the possible reason. Any one will help please.

401 after a 302
by Marc Soda 14 Mar '14

14 Mar '14

Can someone tell me how to handle a 401 from a 302 redirect? I am attempting to register with the uac module. Normally, I set a failure route for the 401 and call auc_auth(). In this case, I am receiving a 302, sending the register with get_redirects(), then getting a 401. However, Kamailio seems to be ignoring the 401. I see it in an onrely_route, but not a failure route. failure_route[REG_AUTH] { xlog("L_NOTICE","route[REG_AUTH]\n"); # Handle redirects if ($T_reply_code == 302) { get_redirects("*", "Redirected"); t_on_failure("REG_AUTH"); route(RELAY); } else if ($T_reply_code == 401) { uac_auth(); t_on_reply("REG_REPLY"); route(RELAY); } } route[RELAY] { xlog("L_NOTICE","route[RELAY] ($rm)\n"); if (is_method("INVITE|BYE|SUBSCRIBE|UPDATE")) { if (!t_is_set("branch_route")) t_on_branch("MANAGE_BRANCH"); } if (is_method("INVITE|SUBSCRIBE|UPDATE")) { if (!t_is_set("onreply_route")) t_on_reply("MANAGE_REPLY"); } if (is_method("INVITE")) { if (!t_is_set("failure_route")) t_on_failure("MANAGE_FAILURE"); } xlog("L_NOTICE","t_relay()'ing ($rm)\n"); if (!t_relay()) { sl_reply_error(); } exit; } Thanks!

Soft phone Issue
by Owais ul Haq 14 Mar '14

14 Mar '14

Hello, I have configured a kamailio server on my local network, gave it a dummy domain like "abcd.tk". I have a number of computers on my local network. I want to run eyebeam on them and connect to my kamailio server. Server is running fine. When I try to connect Eyebeam to Server, it goes to DNS to find IP for "abcd.tk". I have entered the value "192.168.1.10 = abcd.tk" in "hosts" file of all machines. File is located at "C:\WINDOWS\system32\drivers\etc\hosts". On other hand, when I ping abcd.tk from client computers. They ping 192.168.1.10. So Operating systems verify the entry "192.168.1.10 = abcd.tk", but problem lies with soft phones. I have tried X-Lite and Eyebeam. How can I make softphone understand that abcd.tk = 192.168.1.10 and please go to this adress, not DNS ?? Help please :( Regards, Awais.

help with SIP Notify message, to make a endpoint (SPA504G and similar) to reboot.
by Pedro Niño 13 Mar '14

13 Mar '14

Sorry for intruding, but this is puzzling me a lot. I followed the guide to make Kamailio work with asterisk and realtime, Kamailio version 4 and asterisk 11. (http://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb ) up until now its working, and now want to get the phones (CISCO SPA504G, former linksys) to get the SIP notify command and reload to get their new config, from the asterisk cli the cli command is "sip notify spa-reboot <username>" The problem is that, using the setup in the guide, the phones registers with kamailio, kamalio then strip the password and register with no password to the asterisk, as supposed to be. by that, when asterisk sends the SIP Notify with the reboot commands, it arrives to the kamailio, and is forwarded to phone, and the phone answers with a '401' and a digest. In the flow, the kamailio (in the middle) receives the 401 and sends again the sip message to asterisk, and asterisk uses the digest to cipher the password and reply, but as asterisk is configured with no password, the reply contains as 'wrong' password (the empty/blank one) is there any way to make kamailio intercepts again that '401' and reply with a crafted message, with the right digest, password, (the one in the ul table) and user, so the phone can accept the order and reboots? The other (ugly) option, is to remove the auth from the phone, for the Sip Provisioning, but that would leave and open door to a reboot attack without auth needed from any IP. And I dont like that option. As we talk, I managed to create a routing logic, but is that the right approach? : =================== request_route { if (is_method("NOTIFY")) { #xlog("NOTIFY received: $rs"); t_on_failure("MANAGE_FAILURE_401"); #try to intercep a 401 } ..... } failure_route[MANAGE_FAILURE_401] { if (t_check_status("401")) { #401 detectado dentro de un Notify, #probablemente ha sido por una orden de reboot. #hay que construir un paquete e intentar enviar, con el digest adecuado.... $uac_req(method)="NOTIFY"; $uac_req(ruri)="sip:"; $uac_req(furi)="sip:"; $uac_req(turi)="sip:"; $uac_req(hdrs)="Contact: <sip:"+ ">\r\n"; #Paquete construido, debe ser enviado uac_req_send(); xlog("401 detectado"); # exit; } =================== Thanks in advance.....

Bizarre dialog profile tracking behaviour
by Alex Balashov 13 Mar '14

13 Mar '14

Hello, We've got an issue we've been trying to track for days with 'dialog', where the dialogs go through the following life cycle: 1. INVITE --> 2. <-- 407 challenge 3. ACK --> 4. INVITE --> 5. <-- 100 Trying 6. <-- 180 Ringing 7. <-- 183 Session Progress 8. <-- 200 OK 9. ACK --> 10. BYE --> 11. <-- 200 OK Somewhere around steps #6-7 (18x messages), the dialogs no longer appear to be counted in the dialog profile they're attached to, as gleaned from 'kamctl fifo profile_get_size <profile> <key>'. The dialog count in the profile falls to 0. Naturally, I suspected a SIP issue that was preventing the dialog state from being tracked correctly. However, subsequent investigation revealed that these very same dialogs are tracked just fine throughout their entire lifetime. The 'kamctl fifo dlg_list' command shows them to have the right states at the right times. So, the dialog itself isn't going away from tracking. Its attachment to the given profile seems to be the issue. I can't find any logical explanation for this in the code, nor any technical reasoning to support this hypothesis. However, that's what seems to be happening. I'm not sure that this is the issue; it might be another issue masquerading as having this effect. I'm just trying to rule possibilities out. Are there any situations that can cause a dialog that is otherwise being normally tracked to be dumped from a profile of which it was previously part?

Problemas with kamctl ul show - Kamailio 4.1
by Raphael Borges 13 Mar '14

13 Mar '14

Hello, I'm having a problem with the command kamctl ul show, and I do not understand what is happening. On my server when I run just "kamctl ul show" command works fine but when I run "kamctl ul show [<username>]" an error happens. Before when I was using Kamailio 3.1, its work ok. I looked for some documentation and found nothing about this. For example: *$ /home2/local/kamailio/sbin/kamctl ul show* Domain:: location table=512 records=1 max_slot=1 AOR:: 2501 Contact:: sip:2501@192.168.XXX.XXX:5060;transport=udp Q= Expires:: 3594 ... Domain:: aliases table=512 records=0 max_slot=0 *$ /home2/local/kamailio/sbin/kamctl ul show 2501* 404 AOR not found Thanks for Help. Best regards. Raphael

Reminder: about private emails
by Daniel-Constantin Mierla 12 Mar '14

12 Mar '14

A message sent almost one year ago, but based on volume of private emails related to free support on SIP, Kamailio or other applications, perhaps it is time to refresh, with couple of extra bits for clarification: - http://lists.sip-router.org/pipermail/sr-users/2013-April/077700.html >>> I would like to remind that, at least in my case, writing emails directly without cc-ing the mailing list is not recommended. The rule is also suggested in the mailing lists presentation page: - http://www.kamailio.org/w/mailing-lists/ Unless I asked explicitly for a private email with some specific details, the message will not be noticed and therefore not replied. I use this email address for many public mailing lists and it is intended only for that usage, I am reacting based on the filters I created, unmatched messages getting the lowest priority. There are several common sense as well as technical reasons. Here are some along with other suggestions to improve the likeliness of getting an answer: - we are not answering questions on mailing lists to help only one person, but also other people that may have similar issues in the future -- they can find the answers in the archive with a search engine. Also, other people subscribed to the list can learn from conversation or contribute to the discussion, resulting in better outcome - the amount of unexpected messages is very high -- it is practically a zero chance to get to the folder with messages that didn't match any filter (thus your message is not going to be replied) - whenever I find time, the first emails I answer are those coming on mailing lists. They are many there as well, people are traveling or having other personal or business projects, so sometime is good to send a reminder if a question does not get an answer - starting with negative approach or no technical content, like you are going to use something else if you don't get this instantly, or this application is missing what so ever tutorial giving exactly the solution you need, or simply asking for full config of complex requirements, is not helping at all, but actually making people to ignore your messages. Start with what you tried and where you got stuck. Everything you get is for free, nobody here owe you anything. Therefore, if anyone sent me a private message asking about kamailio or continuing a discussion started on mailing lists, then the messages have to be resent on mailing list if one wants an answer. A quick look in my unfiltered folder revealed hundreds of messages during the past year, soon many will be deleted anyhow. Note that you can always mask sensitive data (e.g., replace passwords, IP addresses) before sending logs or config file.

Kamailio LCR unable to relay new calls, memory issue
by Camila Troncoso 12 Mar '14

12 Mar '14

Hi, Last Friday I presented a increase of load in kamailio by a client. The load was almost twice as usual. By that time I encountered with many issues in kamailio. The calls were not relay to gateways, and a lot of messages about memory were appearing in log file. Kamailio didn't crash. When I remove the extra traffic all went back to normal. Is there a issue about memory leak or about to few memory resources to manage this amount of traffic?

Kamailio Proxy for Freeswitch
by jay binks 12 Mar '14

12 Mar '14

So im using Kamailio as a load balancer and proxy in-front of a few Freeswitch boxes. Im not going to use RTP Proxy, as my FS boxes will be public on the internet ( Direct RTP connection is fine ). I want ALL SIP to go via Kamailio, but the issue im running into is that the SIP Contact header has the FS IP address in it in some cases. ( 180's etc ) Every bit of documentation I can find about re-writing the Contact header is geared around NAT, and thats not what im trying to do here.. Can anyone give some pointers on how to basically topology hide the FS boxes on the SIP front but leave their IP in the SDP. im going to have the firewalls setup so the SIP Can ONLY come from kamailio, so its quite important I get this all right. Any pointers would be appreciated. Thanks Jay

Fail Safe Environment for kamailio
by Owais ul Haq 12 Mar '14

12 Mar '14

Hello, Guys, I need some help. I am tasked to deploy "Fail Safe Architecture" for already running Kamailio Server in our organization. Presently one Kamailio Server is serving the cause with one internet connection and database on MySQL running on Windows 2008 Server R2(which is attached to kamailio server on other LAN card). Now the requirement is to deploy redundancy for internet connection and kamailio server. Like they want two kamailio servers running parallel, so if one fails, other will automatically take over and service will be available to users without any obstruction. At any cost, my organization want to absolutely minimize any possible blackout. To further elaborate my point. Here is the network we want. 2 incoming internet connections to 2 kamailio servers. Both attached to a single database placed at the backend. Now is it possible ?? If not what are constraints ?? What workaround is possible ?? I seriously need help as it is matter of job. Thanking in advance for help. P.S : kamailio server is running of Fedora machine in our environment. Cheers.

hello folks, i'm really new with kamailio (a couple fo days) and I need some suggestion/samples/idea/HELP to realize my environment. I've been starting to read the docs on website but there are a lot and i don't know where start and which kind of modules need to use I''d like to realize a trunk from kamailio and asterisk. Each one has their own sip users. kamailio sip users are some inside network and some outside network (behind nat) Could someone be son kind to show me the right way to configure kamailio for incoming/ougoing calls from/to asterisk and for using sip peers (behind nat and not)?. Also same samples are really preciated. Thanks a lot in advance Kind regards Lorenzo -- "Chi vive sperando muore cagando ...

how to get value of route param?
by Juha Heinanen 10 Mar '14

10 Mar '14

rr module has check_route_param(re) function that can be used to check if local route header has a param that matches re. however, there does not exist a function to find out what is the value of a given rr param. for example, if route header has param ;param=foo, how to extract value foo of param? there is @rr.uri.params select that together with {param.value,name} transformation might be able to do the job? -- juha

How to encode domain in username for Asterisk REGISTER forwarding (was: How to configure Kamailio + Asterisk (on same server) to route between several disjoint networks?)
by Alex Villacís Lasso 10 Mar '14

10 Mar '14

On the previous issue (disjoint networks), I eventually settled for binding Asterisk on localhost:5080, and using rtpproxy to route media to the networks as required. The only snag is that I had to write a script to rewrite the Kamailio configuration in order to take current IPs into account. Now, for the same project. What I want now is to be able to express multiple domains with an Asterisk backend. That is: given pbx.company1.com and pbx.company2.com, two DNS addresses that point to the same server, I want to have separate accounts bob(a)pbx.company1.com and bob(a)pbx.company2.com, with separate registration and accounting, without collisions. I know about the Kamailio "domain" module, and I have enabled WITH_MULTIDOMAIN and filled the kamailio.domain table for it to work. Now the authentication is taking domains into account. Next, I want to express two non-colliding registrations for Asterisk. What comes to mind is username rewrite - Kamailio sees bob(a)company1.com, and forwards a REGISTER to Asterisk using bob_company1_com as the SIP username. I am looking right now at the WITH_ASTERISK block that uses the uac module: # Forward REGISTER to Asterisk route[REGFWD] { if(!is_method("REGISTER")) { return; } $var(rip) = $sel(cfg_get.asterisk.bindip); $uac_req(method)="REGISTER"; $uac_req(ruri)="sip:" + $var(rip) + ":" + $sel(cfg_get.asterisk.bindport); $uac_req(furi)="sip:" + $au + "@" + $var(rip) + ":5060"; $uac_req(turi)="sip:" + $au + "@" + $var(rip) + ":5060"; $uac_req(hdrs)="Contact: <sip:" + $au + "@" + $sel(cfg_get.kamailio.bindip) + ":" + $sel(cfg_get.kamailio.bindport) + ">\r\n"; if($sel(contact.expires) != $null) $uac_req(hdrs)= $uac_req(hdrs) + "Expires: " + $sel(contact.expires) + "\r\n"; else $uac_req(hdrs)= $uac_req(hdrs) + "Expires: " + $hdr(Expires) + "\r\n"; uac_req_send(); } #!endif The above is the non-encoding version. What is the best way to modify it to do a domain encoding in the username? Or, if a better solution exists, what is it?

I´m presenting the problem that its stops jumping after 12 gateways and returns the message 500 Forking capacity exceeded (12/SL). I need to increase this limit , so all the gateways in the list give the call a try.

Hi folks, I'm new to Kamailio, and I am looking for some documentation on how to write config files, what should be included... etc..

Incorrect IP address in path header
by Rob Moore 06 Mar '14

06 Mar '14

Hi All, So an interesting one here. I'm doing pass through registrations using the dispatcher module in Kamailio and I'm using the Path Module to set the Path header In Register request so that Freeswitch knows to follow the route via Kamailio to find the sipPhone in future. In summary: [SIP Phone]------[NAT]------[(externalip)Kamailio(internalip)]-------[FS-Registrar] The problem I'm having is that the Path header is being added with the external ip address of the Kamailio instance not the internal ip e.g. "Path: sip:(externalip);transport=tcp" which mean FS doesn't root new calls out to the SIPPhone correctly via kamailios internal ip. I have noticed that if I remove the ;transport=tcp from the FS-Register address in my dispatcher group so that the last hop (from kamailio to FS-Register) is done over UDP then the problem corrects itself. (although this does present new issues whilst calling out back along the path from FS, and we also have a prerequisite to use TCP so this doesn't help). Has anyone had any experience of this issue? I can't see what I've done wrong here. Many Thanks Rob

dialog module with DB Backend
by jay binks 06 Mar '14

06 Mar '14

Hi all, im using the dialog module with db_cassandra backend.. I dont believe this issue is related to cassandra, but its worth mentioning anyways. so... I run kamailio, make calls, see dialogs in the DB.. and I Can use "kamctl mi dlg_list" and see that dialogs go away when I hangup a call.. When I query the DB Backend, I still see the queries, but they have a state of 5. I Initially thought this was a bug, but it seems dialogs in state 5 get cleaned up after a period. so I moved on. now , lets restart kamailio.. kamailio loads all dialogs on startup, after kamailio starts I call "kamctl mi dlg_list" again, and it shows all my dialogs from the DB. they DO show as "State 5" but for some reason, these dialogs appear to stick around for a long time, and the bigger issue it causes me is that my channel limiting ( using get_profile_size ) seems to consider these dialogs ( in state 5 ) as being active calls. Please someone point me in the right direction... :) what am I doing wrong ? ( or is this a bug somewhere ) Sincerely Jay

Releasing 4.1.2, 4.0.6 and 3.3.7
by Daniel-Constantin Mierla 06 Mar '14

06 Mar '14

Hello, we are considering to release new versions from stable branches of Kamailio starting with Thursday, March 6. First is v4.1.2 from latest stable branch and if the time allows in the same day, the v4.0.6. The reason to release v3.3.7 is to have a proper debian packages built and hosted on the new repositories -- the specs had a conflict for latest 3.3 version of some sub-packages. If there are known issues that were not addressed, please report them to the tracker. Cheers, Daniel -- Daniel-Constantin Mierla - http://www.asipto.com http://twitter.com/#!/miconda - http://www.linkedin.com/in/miconda Kamailio World Conference - April 2-4, 2014, in Berlin, Germany http://www.kamailioworld.com

How to add some text at end of body line with subst_body
by Barthel Marco (CI/AFU1) 05 Mar '14

05 Mar '14

Hi, I'm trying to add some string at the end of some line in the body/sdp of a SIP INVITE for testing some interoperability. The following line a=crypto:1 AES_CM_128_HMAC_SHA1_80 inline:NwC8z5MsyCWbpJJo1n2BDS8DkGuUU2cIt9KRUqPU should be converted to a=crypto:1 AES_CM_128_HMAC_SHA1_80 inline:NwC8z5MsyCWbpJJo1n2BDS8DkGuUU2cIt9KRUqPU UNENCRYPTED_SRTCP I tried with this: subst_body('/(a=crypto.*)\r/\1 UNENCRYPTED_SRTCP\r/g'); but it does not match just using subst_body('/(a=crypto.*)/\1 UNENCRYPTED_SRTCP/g'); matches but results in this (carriage return between key and "UNENCRYPTED_SRTCP"): a=crypto:1 AES_CM_128_HMAC_SHA1_80 inline:NwC8z5MsyCWbpJJo1n2BDS8DkGuUU2cIt9KRUqPU\rUNENCRYPTED_SRTCP using Kamailio 3.3.6 Any ideas?

msilo config
by Peter Villeneuve 05 Mar '14

05 Mar '14

Hi, Can someone share a working msilo config for 4.1.1? I've tried following older tutorials out there but they no longer seem to apply. I just want to test out msilo with the default kamailio config in 4.1.1, but the current example in http://kamailio.org/docs/modules/4.1.x/modules/msilo.html doesn't work for me. Specifically, I get an error regarding the syntax in t_on_failure("1"); Any help or pointers appreciated. Thanks

Incorrect Contact address
by Marc Soda 05 Mar '14

05 Mar '14

I have Kamailio setup as a proxy in front of a backend server (Asterisk). When I make a call through the proxy, the Contact header in the 200 OK that is returned to the client has the IP of the backend server in it. Thus, the client is sending it's ACK directly to the backend server. Is there a special method to rewrite the Contact header to be Kamailio's IP? Where is a good place in the config to do this? (my config is loosely based on this: http://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb) Thanks! Marc

Reload memory leaks issues.
by Uri Shacked 05 Mar '14

05 Mar '14

Hi, kamailio ver 3.3.6. I load approximately 100Mb of data into memory. And my shared memory size is 4Gb. It is CARRIERROUTE, DIALPLAN, MTREE and HTABLE combimations. My system has to be synced with DB that is being updated frequently. So, I reload the data every 1-2 minutes. I notice that the shared memory usage is increasing at 1% every 18-19 reloads. I use mem_join = 1 and no mem_join at all. I compiled with C_DEFS+= -DMEM_JOIN_FREE and even with -DF_MALLOC. Tried different options, still, the issue keeps on going and it is very frustrating... Anyone has the same problem? BR, Uri

invalid xmlrpc response from pkg.stats?

there a several <struct>s in the <value>, which according to my understanding is violation of the spec. instead, the response should be like this: <?xml version="1.0"?> <methodResponse> <params>

INVITE proxy auth
by Marc Soda 04 Mar '14

04 Mar '14

Hey all, I have a pretty general SIP question that I'm hoping some of you can shed some light on. I hope this ok for the list. I am setting up a SIP proxy with Kamailio. The backend server (Asterisk in my case) requires authentication. Is it standard/best practice to require a proxy to authenticate to a backend server for INVITEs? I am already registering, with authentication, on behalf of the client, i.e, the client registers to the proxy, then the proxy registers to the backend server, all with authentication. I was hoping not to have to do this on INVITEs, but if I don't I'm left with the following: client proxy backend | -------INVITE-------> | | | <--------407--------- | | | ---------ACK--------> | | | ----INVITE(auth)----> | | | <--------100--------- | | | | -------INVITE-------> | | | <--------401--------- | | | ---------ACK--------> | | <--------401--------- | | | ---------ACK--------> | | | ----INVITE(auth)----> | | | <--------100--------- | | | | ----INVITE(auth)----> | | | <--------100--------- | | | <---------OK--------- | | <---------OK--------- | | | ---------ACK--------> | | | | ---------ACK--------> | It works, but, it's terrible... Before I try to make it work differently, what do you all think it should do? Marc

Re: [SR-Users] Regd. Stored procedure support in Kamailio
by Alex Balashov 04 Mar '14

04 Mar '14

You can executed any SQL statements you want through 'sqlops', including invocation of stored procedures. Our Kamailio-based Class 4 routing/trunking product is built almost entirely on Postgres stored procedures. We have dozens of them. As to whether they are "really needed", I don't know how to answer that. :-) In our case, we decided they were really needed because they offer the opportunity to execute complex business logic beyond what Kamailio's relatively primitive route scripting language can offer, while eliminating unnecessary back-and-forth data interchange between Kamailio and the database. Stored procedures and triggers also execute in a transactional manner, which is additionally beneficial.

Regd. Stored procedure support in Kamailio
by Shankar 04 Mar '14

04 Mar '14

Hello All, Does Kamailio support invoking stored procedures instead of sending plain DB queries already? We have been asked to migrate to stored procedures. I am trying to estimate the effort involved in migrating Kamailio code to support stored procedure. Other question that comes to my mind is whether stored procedures are really needed in Kamailio. Can someone please clarify? Regards, Shankar

REGISTER failure_route 401 problem
by Marc Soda 03 Mar '14

03 Mar '14

I have a Kamailio server setup which is registers to a back end server on behalf of endpoints. The endpoints can register to Kamailio but Kamailio is failing to register to the server when I put a NAT device in front of it. Without the NAT device it works fine. The problem is the 401 that comes back seems to be ignored by Kamailio. I have a failure route setup to auth, but it is never hit. I see the 401 in onrely_route, but not the failure_route. I'm assuming it's a NAT issue because removing the device fixes the issue. Anyone have any ideas? The 401 being ignored: SIP/2.0 401 Unauthorized Via: SIP/2.0/UDP 10.0.10.11;branch=z9hG4bKe5d6.178378f7.0;received=198.XXX.XXX.XXX Via: SIP/2.0/UDP 127.0.0.1:12354 ;rport=6545;received=198.XXX.YYY.YYY;branch=z9hG4bK-1879-1-3 From: <sip:sip7878_spqa@64.YYY.YYY.YYY>;tag=1 To: <sip:sip7878_spqa@64.YYY.YYY.YYY>;tag=as00e32130 Call-ID: 1-1879(a)127.0.0.1 CSeq: 2 REGISTER User-Agent: CoreDialPBX Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY, INFO Supported: replaces WWW-Authenticate: Digest algorithm=MD5, realm="fe-c7c5-9o.domain.com", nonce="151e4f60" Content-Length: 0 Thanks, Marc

I found the solution myself, anyone having a similar issue in the future can use msg_apply_changes() from textopsx module after append_hf line.

Adding Path header for the current request.
by MAXX ... 02 Mar '14

02 Mar '14

Hello, I need to add a Path header to the current request so the save method of registrar module will save the location with the path value to the db. I made the necessary settings for the registrar module but I couldn't be able to add the header. Neither "append_hf" nor "add_path" of path module works since they don't add the header to the currently processing request. $hdr pseudovariable is readonly so I couldn't modify it as well. What can I do to make this happen? Also the reason I need this is to let people registered to different registrars to be able to call each other via their current tls connections to their respective registrars. Thanks In Advance.

How to configure Kamailio + Asterisk (on same server) to route between several disjoint networks?
by Alex Villacís Lasso 01 Mar '14

01 Mar '14

As part of a project, I have installed a CentOS 6 test system (a virtual machine) with Asterisk 11.7.0 and Kamailio 4.1.1 downloaded from http://download.opensuse.org/repositories/home:/kamailio:/telephony/CentOS_…. I am trying to setup a combination of Kamailio and Asterisk that will route SIP calls between all the configured networks in the test setup, in addition to being capable of using Asterisk in order to handle PSTN and IAX2 calls. I am using the following online guide to modify my kamailio.cfg: http://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb . Based on this, I generated the attached patch for my Kamailio configuration My test setup has the following network interfaces: eth0: 10.1.0.3, on network 10.1.0.0/24 eth1: 192.168.5.18, on network 192.168.0.0/16 eth2: 10.0.0.2, on network 10.0.0.0/24 lo: 127.0.0.1, on network 127.0.0.0/8 I first configured Asterisk with SIP realtime support (with no Kamailio), and tested that all configured accounts could register from all interfaces, and that Asterisk could properly route media between any two disjoint networks. After installing Kamailio, the guide called for disabling Asterisk SIP authentication by setting passwords to NULL, and moving Asterisk SIP to a different port (I chose 5080) so that Asterisk and Kamailio could run on the same machine. At this point, the SIP clients (one softphone and one VoIP phone) can now register at port 5080 without authentication. In the process of changing my Kamailio configuration according to the attached patch, the guide says that I should configure the IP of the network interface as the value of asterisk.bindip and kamailio.bindip. After performing all required changes, Kamailio does take over authentication at the default port of 5060. Testing shows that for all SIP clients with IPs belonging to the same network as the configured asterisk.bindip, both registration and media exchange work correctly, and that the SIP clients are still capable of calling into the Asterisk dialplan, and therefore, routing into Asterisk resources. For SIP clients in disjoint networks, the failure mode depends on whether mhomed is enabled or disabled in kamailio.cfg. For mhomed=0 (or unset), I have the following situation between the two SIP clients (one at 10.1.0.1, the other at 10.0.0.3), as shown by "sip show peers" in Asterisk (when asterisk.bindip is set to 192.168.5.18): Privilege escalation protection disabled! See https://wiki.asterisk.org/wiki/x/1gKfAQ for more details. Name/username Host Dyn Forcerport ACL Port Status Description Realtime gatitoscomx64am_100/gatit 10.1.0.3 D N A 5060 OK (16 ms) Cached RT gatitoscomx64am_101/gatit 10.0.0.2 D N A 5060 OK (36 ms) Cached RT gatitoscomx64am_IM101 (Unspecified) D N A 0 UNREACHABLE Cached RT 3 sip peers [Monitored: 2 online, 1 offline Unmonitored: 0 online, 0 offline] If I try to call from one SIP client to an extension in the Asterisk dialplan that does NOT map to a SIP client in a disjoint network, the media exchange works (with negotiatied media IP in the same network as the SIP client), regardless of whether the calling client belongs in the same network as asterisk.bindip. If I try to call from the same SIP client to an extension that maps to a SIP client in a disjoint network, the call fails, and I get the spoken message about the user at extension such-and-such being unavailable. Additionally, I get the following error message in the Asterisk logs: [Feb 25 16:53:14] NOTICE[13807][C-00000003] chan_sip.c: Call from 'gatitoscomx64am_101' (10.0.0.2:5060) to extension 'gatitoscomx64am_101' rejected because extension not found in context 'gatitoscomx64am-from-internal'. For mhomed=1, the output of "sip show peers" changes to the following (when asterisk.bindip is set to 192.168.5.18): Privilege escalation protection disabled! See https://wiki.asterisk.org/wiki/x/1gKfAQ for more details. Name/username Host Dyn Forcerport ACL Port Status Description Realtime gatitoscomx64am_100/gatit 192.168.5.18 D N A 5060 OK (19 ms) Cached RT gatitoscomx64am_101/gatit 192.168.5.18 D N A 5060 OK (34 ms) Cached RT gatitoscomx64am_IM101 (Unspecified) D N A 0 UNREACHABLE Cached RT 3 sip peers [Monitored: 2 online, 1 offline Unmonitored: 0 online, 0 offline] From wireshark sniffing, I can see that the SDP payload sent from the client to Kamailio contains the IP address of the client, which is accessible by both Kamailio and Asterisk. However, the SDP payload in the OK response sent back to the client contains a media port with the IP address of asterisk.bindip (the one that appears in the "Host" column in the "sip show peers" report), not the IP address of the interface that received the INVITE. This results in broken media negotiation for all SIP clients belonging to networks other than the one that contains asterisk.bindip. In either case, I have to hardcode an IP address in kamailio.cfg, which is not satisfactory. IPs assigned to interfaces can and do change, especially if the interface is managed with DHCP. To escape this, I tried setting asterisk.bindip to 127.0.0.1, but since apparently localhost is also a disjoint network, all of the above described problems apply. Related to these issues, I am not satisfied with leaving Asterisk running unauthenticated SIP at the nonstandard port. Somebody suggested blocking the port with iptables, but I do not want to rely on this alone. I tried setting bindaddr=127.0.0.1 so that only Kamailio gets to talk to Asterisk, but this also has the side effect of restricting the media negotiation to localhost only. I am asking for help in building a Kamailio/Asterisk configuration that will support all of the networks and route media between all of them, just as if Asterisk were the only program running. Ideally, the configuration should not encode the current IP of any interface (except, maybe, localhost). What is the official name (if any) for the setup I am describing above? Does it have a standard setup procedure? How is Asterisk secured so that clients cannot bypass authentication using the Asterisk SIP port directly?

Replacing an ACME Packet Net-Net SBC
by Francesco Maria Magnini 01 Mar '14

01 Mar '14

Hi, I would like to have some suggestions about a full replacement of an ACME Packet Net-Net Session Border Controller. By now, ACME SBC performs all the SBC functionalities, mainly: - it is used as a SIP endpoint for SIP client registrations - it is used as a SIP endpoint for interconnection to multiple SIP carriers via SIP trunks - it is used for NAT traversal In this deployment, the SIP Server communicates only with the SBC and this one takes care of the communication between the SIP Server and the external SIP entities (UA clients, SIP Trunks). In this scenario, can I consider to replace the SBC with Kamailio?

What is required to enable TLS on non-standard port?
by info＠vintageelectronics.ca 01 Mar '14

01 Mar '14

Kamailio running in Fedora 19 box. The client (Jitsi) can only connect over TCP. If connecting over UDP, the clients connect, but cannot send/receive messages. Cannot connect over TLS at all. Ultimately I will need to run with TLS over 5065 port or higher. Tried using different listen directives, different port directive, but kamailio either does not start, or only listening on one TCP port. I've set up two SRV records, one for _sip on port 5065 and another for _sips on port 5066. Both pointing to the Fedora box. In Jitsi I have to specify port # and when I set it to 5065 over TCP it works, but 5066 over TLS never connects. What am I doing wrong? Thank you.

Add Header
by Tony Turner 28 Feb '14

28 Feb '14

Hi, customers PBX----trunk-----kamailio------------freeswitch-------------carrier We already add Trusted IP’s via SIREMIS 4.0 is it possible with Kamailio to have customers calls come in on a trusted IP and when they send calls we add a header with a [client id] which we can remove on the next ip switch upstream So example Call comes in from customer with IP: their trusted IP source xx.xx.xx.xx add header with their client ID route to PSTN Then my upstream switch will process the customers call and remove the header before sending to our voip carrier. Basically my ip switch will evaluate the client id header for billing, process and strip the header back out. Thanks Tony

proposed patch for the registrar module - crash fix
by Dragos Oancea 28 Feb '14

28 Feb '14

Hi We think that we found and fix a bug in the registrar module. The bug is hard to reproduce, and it crashes our Kamailio from time to time (once at 2-3 weeks for us) . In save.c, function update_contacts() there are two places where we free() a pointer and then we reuse it, line 700 and line 730: while(ptr){ ptr0 = ptr; if(ptr!=c) ul.delete_ucontact(_r, ptr); ptr=ptr0->next; } And then from inside delete_ucontact(_r,ptr) we call mem_delete_ucontact(_r, _c) which calls free_ucontact(_c) , which calls shm_free(_c) . _c is actually our ptr. If another process writes at the location pointed by ptr during the "while" loop , the current process will crash. The bug affects 4.0.4, 4.0.5 and maybe older versions. We keep the location table in memory, no database backend, and we do alot of REGISTER/un-REGISTER in our environment, and maybe that's why this bug was not spotted by the community before. Just to clarify, this fix is in relation with this post: http://lists.sip-router.org/pipermail/sr-dev/2014-February/022934.html Please take into consideration the attached patch provided by the Libon Voice Team. Regards, Dragos Oancea

keep buddy list - best way
by Mihai Marin 27 Feb '14

27 Feb '14

Hello Sirs, I'm a little confused getting a decision about implementing buddy list (step: presence & IM). What is the best way for keeping the contacts list: xmpp or xcap? You will say probably xcap server but even if I intend to use in the future an xmpp gateway in order to be able to communicate sip with with xmpp servers like google - google talk? And why xcap? Because most of the clients has the possibility to connect to a xcap server to get the buddy list? From web perspective I think both are OK because of the xhttp module power in kamailio to get the buddy list xml. Thank you. Best regards, Mihai M

Sorry ... I disagree at all .... All that features you mention, could be done with kamalio ... BUT you have to work on your cfg to get them. You don't get then out of the box.

kamailio with mediaproxy-ng, 488 Not Acceptable Here
by Mihai Marin 26 Feb '14

26 Feb '14

Hello Sirs, I have a problem configuring kamailio with mediaproxy-ng and I'm asking for help. I managed to build everything, kamailio find support for mediaproxy-ng using rtpproxy-ng.

coredump on using jsonprc_request
by davy van de moere 26 Feb '14

26 Feb '14

Gents, I’ve stumbled upon a coredump when using jsonrpc_request. I might be expecting the wrong things from jsonrpc_request. I was hoping to use it in combination with CNXCC, and have jsonrpc_request get a maximum duration for every call, as a fraud avoidance mechanism. I tried this with the branch 4.1 and master. Both behave identical. So from the kamailio-basic.cfg example, I just added this line around line 350 (just above route(SIPOUT)): jsonrpc_request("bar.sendsms", "{'ru':'$rU','rb':'$rb'}", "JSONRESPONSE", "JSONERROR", "$var(result)"); Doing a ngrep on the netstrings I have: interface: venet0 (127.0.0.2/255.255.255.255) filter: (ip or ip6) and ( port 7080 ) # T 10.66.8.42:44995 -> 192.168.60.45:7080 [AP] 94:{ "id": 2, "jsonrpc": "2.0", "method": "bar.sendsms", "params": { "ru": "", "rb": "" } }, ## T 192.168.60.45:7080 -> 10.66.8.42:44995 [AP] 43:{"jsonrpc": "2.0", "result": "12", "id": 2}, ####^Cexit 7 received, 0 dropped I do get some results from the JSONRESPONSE route. But when launching a call, or when sending just a register packet, kamailio gives up with: Feb 26 06:29:11 SBC01 kamailio[18043]: WARNING: tm [t_lookup.c:1537]: t_unref(): WARNING: script writer didn't release transaction Feb 26 06:29:12 SBC01 kamailio[18033]: : [mem/q_malloc.c:468]: qm_free(): BUG: qm_free: freeing already freed pointer (0xb4c01624), called from tm: h_table.c: free_cell(157), first free tm: h_table.c: free_cell(157) - aborting Feb 26 06:29:12 SBC01 kamailio[18023]: ALERT: [main.c:775]: handle_sigs(): child process 18033 exited by a signal 6 Feb 26 06:29:12 SBC01 kamailio[18023]: ALERT: [main.c:778]: handle_sigs(): core was generated Feb 26 06:29:12 SBC01 kamailio[18023]: INFO: [main.c:790]: handle_sigs(): INFO: terminating due to SIGCHLD Feb 26 06:29:12 SBC01 kamailio[18041]: INFO: [main.c:841]: sig_usr(): INFO: signal 15 received Feb 26 06:29:12 SBC01 kamailio[18047]: INFO: [main.c:841]: sig_usr(): INFO: signal 15 received Feb 26 06:29:12 SBC01 kamailio[18043]: INFO: [main.c:841]: sig_usr(): INFO: signal 15 received Feb 26 06:29:12 SBC01 kamailio[18048]: INFO: [main.c:841]: sig_usr(): INFO: signal 15 received Feb 26 06:29:12 SBC01 kamailio[18023]: : [mem/q_malloc.c:468]: qm_free(): BUG: qm_free: freeing already freed pointer (0xb4c01624), called from tm: h_table.c: free_cell(157), first free tm: h_table.c: free_cell(157) - aborting Using the jsonrpc_notification works like a charm. I got coredumps of it, if someone is interested. Side questions are offcourse, am I aiming to use jsonrpc_request for the correct purpose? Are there any other good alternatives? (next to using plain db queries?) Grtz, Davy -- davy van de moere

debian packages from opensuse.org
by Jöran Vinzens 26 Feb '14

26 Feb '14

Hi All, we are using Kamailio 4.1.0 packages from opensuse: http://download.opensuse.org/repositories/home:/kamailio:/telephony-debs/De… During installation it seems, the packages are malformed. Installation of kamailio-mysql-modules and kamailio-xml-modules stops during unpacking with failure: "trying to overwrite '/usr/lib64/kamailio/libsrdb2.so.1.0', which is also in package kamailio 4.1.0" it seem this one file is part of all three packages. There is a way to enforce the installation using dpkg -i --force-all.. but it seems not the right way. Does anyone have an idea how to solve without building own packages? Maybe this is an bug in kamailio Project? Many thanks for all proposals.

Problems while reading from location and parsing expires
by Jöran Vinzens 25 Feb '14

25 Feb '14

Hi All, we are upgrading from kamailio 3.1 to 4.1 and we got stuck at a Problem with usrloc module. While starting up kamailio reads location from DB and try to parse expires date from DB. this is the Problem: Feb 25 11:42:11 hagi /usr/sbin/kamailio[19580]: ERROR: <core> [db_ut.c:90]: db_str2int(): Unexpected characters: [-02-25 11:27:08] Feb 25 11:42:11 hagi /usr/sbin/kamailio[19580]: ERROR: <core> [db_val.c:75]: db_str2val(): error while converting integer value from string Feb 25 11:42:11 hagi /usr/sbin/kamailio[19580]: ERROR: db_mysql[km_row.c:68]: db_ mysql_convert_row(): failed to convert value Feb 25 11:42:11 hagi /usr/sbin/kamailio[19580]: ERROR: db_mysql [km_dbase.c:375]: db_mysql_fetch_result(): error while converting row #0 Feb 25 11:42:11 hagi /usr/sbin/kamailio[19580]: ERROR: usrloc [udomain.c:420]: preload_udomain(): fetching rows failed usrloc Module is configured with db_mode "1" so it saves it's entries by itself. When i have a look on the database it looks good and the expires field is an datetime. From logs it looks like it try to parse a unixtimestamp instead of the datetime. when i truncate the location table it starts perfectly, since there are no entries stored where it could fail parsing expires date. does anybody has similar issue or any suggestions how to solve? found in Version: 4.1.0 many thanks!

pcscf - removing registration entries from hash table
by Daniel Ciprus 24 Feb '14

24 Feb '14

Hello, Our current setup is Kamailio as IMS core and we're observing following behavior: Clients register themselves over TCP so pcscf creates hash table which keeps these information in memory. Once tcp reset occurs for any reason, registration entry stays in the memory and client re-registers himself with new pair ip:port. This kind of behavior creates problem because outbound SIP messages are being forked and requests are sent to non-existent tcp sessions which creates a lot of timeouts and confusion for AS. We're using ims_usrloc_pcscf module to keep reg entries in and as I noticed, with usrloc module, there was an option which automatically removed entry from hash table once tcp session was closed which is not the case in this module. Any suggestions how to get out of this ? thanks for any hints/suggestions. -- Daniel Ciprus Integration engineer http://www.acision.com 9954 Mayland Dr Suite 3100 Richmond, VA 23233 USA T: +1 804 762 5601 E: daniel.ciprus(a)acision.com<mailto:daniel.ciprus@acision.com> ________________________________ This e-mail and any attachment is for authorised use by the intended recipient(s) only.

Kamailio as redirect
by Mike Claudi Pedersen 24 Feb '14

24 Feb '14

i want to setup a test environment to see how kamailio handles redirection. i want to be able to reroute calls between servers, where do i insert the configuration for this? can i append a list of user and destination to make the configuration go through, to see where the call is going? im new at kamailio, and im having a really hard time finding the right documentation to support a redirect server. could somone please give me an example? lets say i have 3 user 1000 1001 1002 and they are at 3 different servers eg. 1000(a)192.168.1.10 1001(a)192.168.1.11 1002(a)192.168.1.12 then i call user 1002 from user 1000, through the kamailio redirect server, which redirects to corresponding servers.

Configuring Kamailio as an upstream proxy for FreeSwitch and which RTP proxy to choose
by Sean Kemball 24 Feb '14

24 Feb '14

Hi New to Kamailio and FreeSwitch, loosely familiar with SIP mechanics, and not a complete network idiot... but please be gentle. :) We're trying to get Kamailio set up in front of a FreeSwitch-based SIP application server, to do some simple policy controls and, using one of the RTP proxy modules, to help handle the media side of things. Our SIP trunks come from our provider on a VLAN addressed as 10.x, and they provide an upstream proxy/media server (10.y address). The link also carries Internet traffic so we're running it through a Cisco ASA which breaks out the VLANs and static NATs the SIP stuff to our DMZ (10.z address). This is where we want to put the Kamailio box, where it should receive the calls and route them back through the ASA to the internal address (10.w range - all 10.w/x/y/z are separate, non-overlapping networks). Outbound calls from the application server (there are very few) should pass back up to Kamailio which will validate the numbers against an approved list (the app should only dial a subset of numbers) and pass them to the upstream proxy if necessary. We need to ensure that inbound calls from outside trombone through our application server so that the caller doesn't get billed for any calls, but this should be the default I think as that side of things is handled by FS (the app stands up a new call and bridges it to the incoming). This topology should allow us to use Kamailio to hide details of the FS app from the outside world, and make life easier for the app developer who should just send/receive to the Kamailio box with no further thought or complexity. If we put the FreeSwitch box in the DMZ where we want to put Kamailio, and then turn on SIP packet inspection in the ASA, calls flow but quality is poor for some callers. If we turn off SIP packet inspection, we get no audio - I can't find any clear Cisco documentation for this but I think the SIP inspection stuff in the ASA seems to handle RTP NAT fixups and the like too. But with no docs it may as well be magic, and I want to remove it if possible. With Kamailio in the DMZ and FS internal, we loosely followed http://kb.asipto.com/freeswitch:kamailio-3.3.x-freeswitch-1.2.x-sbc and hacked out the voicemail and Lua stuff, but couldn't get calls to flow, whether or not we used the SIP inspection on the ASA. We were confused why this example isn't define as WITH_NAT and doesn't use a local RTP proxy. Surely that would be needed? Questions: 1. Should the proposed topology, with Kamailio + an RTP proxy behind a firewall, relaying to FS on an inside interface, work? (Can't see why not) 2. Does it need a local RTP proxy on the Kamailio box, particularly if we turn off the ASA SIP inspect stuff? 3. Can you recommend which RTP proxy to use? There seem to be at least 3 that work with Kamailio. The box is CentOS 6.5, and it would be nice to use known-to-work packages rather than compile from source. (But eh, if I haveta). 4. Can anyone point me to some docs to explain what ports need to be open between the Kamailio box and my upstream proxy/media server? I can be more liberal between inside and DMZ I guess. 5. Is static NAT in this environment going to bite me, or should it be OK? 6. Is there any better documentation that we should be using to make this easier, or should I just man up and try harder?

Change from_uri
by arun Jayaprakash 24 Feb '14

Hello, I have a problem that my calls get rejected by he pstn gateway as my gateway is expecting a DID number instead of a 4 digit extension as the 'from user". Let me explain my situation: 1.

Query about RTP flow
by Nandini madhu 23 Feb '14

23 Feb '14

Dear All, I have read about SIP and RTP packet flows but ended with a question about RTP packets flow logic between client-to client when the SIP session starts. I have a running Kamailio (V 4.0.4) server on ubuntu (12.04) platform which is also configured fro DNS and DHCP servers. And following are my test bed set-ups: Kamailio server (DNS+ DHCP+Kamailio) | Router <----------------------------> Switch<----------------------------> Router | | clientA <--------------------- RTP(audio/video) ? --------------------> client B Now when the SIP session established (SIP Packets have to pass through all the routers and switch to reach Kamailio server), RTP session will start between Client A and B. But What is meant by client to client here ? what is the RTP packets path between the clients to reach their destinations ? Is the RTP packets have to pass through Routers and switch to reach its destination client ? (i.e Client A--->Router 1---->switch -----> Router 2-----> client B) ? What if i connect both client A and client B to the same router ? PS: I have not configured any media-relays (RTPproxy/Media-proxy) Please help me in clarifying all this doubts. Anybody's help will greatly appreciate. Regards, Nandini

RTPProxy/Mediaproxy issue
by Wingsravi R 23 Feb '14

23 Feb '14

Dear Kamailio'ns, I have configured kamailio (V 4.0) with RTPproxy server. Audio/Video call establishments are just fine. With this i have some unknown behaviour in my set-up is that When i am running kamailio server with RTPproxy instance, i am experiencing Jitter, Latency, pixelled audio/video calls. But when i run only Kamailio server without RTPproxy service running, audio/video calls are just fine (no any jitter, latency kind of issues). I also tried with Mediaproxy (AG projects) server but the results are same as like in Kamailio/RTPproxy case. What could be the problem with this set-up ? How can i solve this issue ? Please anybody help me in resolving this problem. Any help will greatly appreciate. Regards. Ravi.

parallel forking and 30x
by Andreas Granig 21 Feb '14

21 Feb '14

Hi, What is the intended behaviour from a general point of view if you get a 1xx on one branch and a 30x on another branch for a parallel fork? >From my understanding, the 30x is a final reply, so it's kept in tm until all other branches are finished, then it enters failure-route with the highest error code (e.g. a 487 if you cancel the other branch). What I actually want is intercepting the 30x and send another INVITE to the Contact of the 30x in the failure route. This works fine if you only have one branch, but it doesn't enter failure route for 30x if you have another active branch (e.g. in ringing state). Would it be possible to create a new branch directly from the reply route, or force to enter failure route for a specific reply/branch? Andreas

Hello, I have deployed Kamailio-3.1 on a fedora machine. And my database is placed on another windows 2008 server situated on the local network. Problem is when I run kamailio. I get the following error from logs. <core> [cfg.y:3416] : parse error in config gile /usr/local/kamailio-3.1/etc/kamailio//kamailio.cfg, line 311, column 31-35 : syntax error <core> [cfg.y:3416] : parse error in config gile /usr/local/kamailio-3.1/etc/kamailio//kamailio.cfg, line 311, column 31-35 : Invalid arguments Line 311 is kamailio.cfg is "modparam ("usrloc", "db_url", DBURL)" And 'DBURL' is defined as #! define DBURL "mysql://openser:5mil5My5ql@192.168.1.20/openser" Can some one please help me out in resolving this error. Secondly I am deploying my database on seperate server for the first time. I have deployed kamailio-3.1 already but with database placed on same machine. Can someone please guide what changings do I need to make in kamailio.cfg and kamctlrc file to make it work. I have made some as per my understanding. Maybe they are a cause of this error.

Re: [SR-Users] FW: Regd. t_suspend() and t_continue()
by Shankar 21 Feb '14

21 Feb '14

Hi, We have found the root cause for the problem that was reported (refer below mail for details) in async module. Below is the brief description, - async_route("Resume", "1") - At time t, the async records are stored at slot 't+1' of async list. - Every second, async records from the async list are processed. - In function 'async_timer_exec', slot = ticks % ASYNC_RING_SIZE; since slot is based on the ticks and if the previous invocation of 'async_timer_exec' did not finish in time, the next tick is missed. Subsequent call to 'async_timer_exec' will be with t+2. Here slot t+1 will be missed and the same will be processed only during next cycle. That means the async records will be stored for the next 100 seconds before they are actually processed. TM module will drop those timed out transactions and hence the error "t_continue: transaction not found" Now we have modified the code in such a way that slot is incremented sequentially irrespective of the ticks that is sent to the function 'async_timer_exec' function. This way we do not see any call failures and all our load runs are successful. If someone is interested we can share the code as well.

[Shankar] We use pkg_mem because we are invoking t_continue from the same process ( using thread ). Secondly, how are you using top to tell that you have a leak? Kamailio's memory is internally managed. [Shankar] After running for say 20minutes, we get out of shared memory error.

Hi, Looking at http://www.kamailio.org/wiki/packages/debs the suggestion is to use http://deb.kamailio.org/ for debian packages. But the last version of kamailio 4.0 here is 4.0.3, and 4.1 doesn't exist. The most files are last modified in 2013-08.. Here for example: http://deb.kamailio.org/kamailio/dists/wheezy/main/binary-amd64/ Is there a new server to get the deb-packages from or should I build from source from now on? /Johan

Re: [SR-Users] NAT traversal problem with Kamailio when trying to communicate between two different LANs

Hi All, I installed Kamailio server on my ubuntu machine. And installed rtpproxy also in the same machine. I didm't make many changes to default configuration files, kamctlrc and kamailio.cfg. Now I am able to communicate between two SIP clients, if both sip clients are in the same LAN. But I am not able to communicate between one sip client in one LAN and the other SIP client in other LAN. Sip Call handling and ringing etc. is ok but there is no voice for this case. I don't have much experience in routing for NAT traversal. I tried to experiment with rtpproxy_manage function in kamailio.cfg file. But I was not successful. Please help me by providing any hints or pointers to proceed further. I am using only Kamailio and Rtpproxy. No other software like Asterisk or FreeSwitch. ************* These are defines I used in kamailio.cfg file: #!define WITH_MYSQL #!define WITH_AUTH #!define WITH_ALIASDB #!define WITH_USRLOCDB #!define WITH_ANTIFLOOD #!define WITH_NAT #!define WITH_PRESENCE listen ip address changed ******************* Kamailio is compiled with following modules: include_modules= db_mysql dialplan presence presence_xml ******** Regards, Sateesh

understanding the sqlops module and kamailio children
by Uri Shacked 20 Feb '14

20 Feb '14

Hi, Following my issue with the above.... 1. Is there a way to see if a worker (child) is processing a transaction for too long (let's say 2-3 sec)? 2. Is there an option to see if the DB connection is alive? (I am familiar with db_mysql options) 3. If all workers are stuck on this "long" transaction, is there a Q for the new INVITES? Can I see how many are there? What I was experiencing is that when my DB was very slow, kamailio crashed after a while.... I will configure db_mysql to ping every 30 sec and timeout after 1 sec. Still, it can create a 3 sec delay for transactions. Any one has an idea? Using the ASYNC module can help here? Does it free the worker to deal with new requests? BR, Uri

Asterisk Ignore "UNREGISTER" because retransmit

Issue with Async module

Hi Daniel, I am using async module to continue the transaction in asynchronously. But I am observing a leak in shared memory. Then i checked the code, we are not freeing the async_item_t after calling t_continue. Same this has checked with MEMDBG=1. Original code: while(1) { lock_get(&_async_list_head->ring[slot].lock); ai = _async_list_head->ring[slot].lstart; if(ai!=NULL) _async_list_head->ring[slot].lstart = ai->next; lock_release(&_async_list_head->ring[slot].lock); if(ai==NULL) break; if(ai->act!=NULL) tmb.t_continue(ai->tindex, ai->tlabel, ai->act); } Changed code: while(1) { lock_get(&_async_list_head->ring[slot].lock); ai = _async_list_head->ring[slot].lstart; if(ai!=NULL) _async_list_head->ring[slot].lstart = ai->next; lock_release(&_async_list_head->ring[slot].lock); if(ai==NULL) break; if(ai->act!=NULL) { tmb.t_continue(ai->tindex, ai->tlabel, ai->act); shm_free(ai); /* Added by surendra */ } } Please correct this if I am wrong. Regards @surendra

Problem with special sip notify (trying to make central provisioning for endpoints)
by Pedro Niño 20 Feb '14

20 Feb '14

Hi, how are you all I have a lab setup for using Kamailio and asterisk, with realtime, and currently I am facing 2 problems. The first one, is when trying to get the phones to reboot. Asterisk send a notify with the message, reboot. But the phone answers with a 401, and asks for a digest. In a normal asterisk environment it would not be a problem, asterisk tries to answer with the user and password cipher with the digest. But because of using this design, asterisk sends the notify with the user and blank password (I am using realtime, so peers can register from kamailio with no password).of course this makes that the phone refuses, as the notify doesn't have the right password. Is there any way to make kamailio intercept the notify sent from the phone and answer with the right credentials? _------------------- Second: When having the users registered in the same scenario, and get an asterisk 'reload', and the users try to make a call before they re-register, only the first call make it thru Of course, as kamailio is in the middle, the users doesnt notice until they try to make a call. In asterisk, I keep seeing the kamailio trying to register and getting a 404. This keeps happening until I sent a sip reload at the asterisk side and wait for the users to register before making calls. Thanks for your time....

Hi all: It's my first mail to the community and I know that will be a great community to share knowledge. OS Debian 6.4 Kamailio 4.1 I have the same problem that Oliver Roth describes in http://lists.sip-router.org/pipermail/sr-users/2013-October/080096.html, but in Kamailio 4.1: Module carrierroute not working starting from version kamailio 4.1 trying to activate carrierroute in kamailio.cfg loadmodule "carrierroute.so" i get the following error when starting kamailio (5794) ERROR: <core> [sr_module.c:599]: load_module(): ERROR: load_module: could not open module </usr/local/lib64/kamailio/modules/carrierroute.so>: /usr/local/lib64/kamailio/modules/carrierroute.so: undefined symbol: cfg_set_error_function 0(5794) : <core> [cfg.y:3408]: yyerror_at(): parse error in config file /usr/local/etc/kamailio/kamailio.cfg, line 245, column 12-28: failed to load module ERROR: bad config file (1 errors) Any idea? Maybe him o someone has the solution. Thanks all for your great work.

Issues with keepalive_timeout
by Kristian Kielhofner 20 Feb '14

20 Feb '14

Hello All, I'm trying to use keepalive_timeout with 4.1.1 as described here: http://lists.sip-router.org/pipermail/sr-users/2012-August/074337.html I believe I've followed these configuration steps and those defined in the nathelper module. Here are the relevant portions of my config: modparam("nathelper", "natping_interval", 60) modparam("nathelper", "keepalive_timeout", 180) modparam("nathelper", "ping_nated_only", 0) modparam("nathelper", "sipping_from", "sip:pinger@domain.com") modparam("nathelper", "sipping_method", "OPTIONS") modparam("nathelper", "sipping_bflag", 9) And of course a setting the correct branch flag (verified) during REGISTER handling: setbflag(9); My goal is to use SIP OPTIONS messages to verify the reachability of all of my endpoints (not just NATd ones). I would just lower my re-registration timeout but there are other issues associated with that kind of change. With my current configuration (after a successful registration) a SIP OPTIONS message is sent and replied to: U 4.2.2.1:5060 -> 4.2.2.2:5060 OPTIONS sip:user372@4.2.2.2:5060;ob SIP/2.0. Via: SIP/2.0/UDP 4.2.2.1:5060;branch=0. From: sip:pinger@domain.com;tag=uloc-5303810e-7c78-1-2273f0eb-9627292. To: sip:user372@4.2.2.2:5060;ob. Call-ID: 8af79586-93072f43-7c4cf55(a)4.2.2.1.

Supported: replaces, 100rel, timer, norefersub. Allow-Events: presence, message-summary, refer. User-Agent: My_UA. Content-Length: 0. . If I kill the registered UA (making it unavailable) Kamailio endlessly sends OPTIONS messages, never receives a reply, and never removes the registration from usrloc: U 4.2.2.1:5060 -> 4.2.2.2:5060 OPTIONS sip:user372@4.2.2.2:5060;ob SIP/2.0.

CSeq: 1 OPTIONS. Content-Length: 0. . (and on, and on, and...) Eventually the registration timeout kicks in, the usrloc entry is removed, and Kamailio stops sending OPTIONS to the (long) unreachable endpoint. Is this expected behavior? What am I doing wrong? Thanks! -- Kristian Kielhofner
