Websocket Path Issues
by Colin Morelli 15 Jul '16

Hey all, I'm using Kamailio as an outbound edge proxy for websocket connections. When my registrar calls out to Kamailio to forward to a websocket connection that has since been killed, rather than just entering the failure branch, it throws a few errors: 5(24) WARNING: <core> [msg_translator.c:2760]: via_builder(): TCP/TLS connection (id: 0) for WebSocket could not be found 5(24) ERROR: <core> [msg_translator.c:1978]: build_req_buf_from_sip_req(): could not create Via header 5(24) ERROR: tm [t_fwd.c:476]: prepare_new_uac(): could not build request 5(24) ERROR: tm [t_fwd.c:1737]: t_forward_nonack(): ERROR: t_forward_nonack: failure to add branches 5(24) ERROR: sl [sl_funcs.c:363]: sl_reply_error(): ERROR: sl_reply_error used: No error (2/SL) Ultimately this means the proxy gets a 500 rather than a 430 flow failed, and the registration sits around in the proxy when it should be removed. Am I missing something obvious to get this behavior? Best, Colin

Re: [SR-Users] Determining if request is from a local domain

Hi all, Solved! As is often the case, after working all morning on the problem, after posting I discovered my error. I noticed that I hadn't included in my post the "alias=" command. It was indeed in my script but I had used aws-rcsstg.voip.systems instead of aws-rcsstg.vvoip.systems ! I don't know how many times I have stared at that but I guess you often see what you want to see...... Apologies for wasting your time.

See xmlrpc, jsonrpc-s or xhttp modules. Obviously, you can send a sip message with tools like sipsak or sipp from command line and handle it inside request_route to execute what route block you want. Sometimes it may just suit executing a route block periodically -- for that see rtimer module.

Hi Marino, How do you mean execute a route !? like enable a route for all calls onwards after the RPC command execution ? or for a specific call engage that route ? If this is to enable/disable a particular route for ALL calls based on a RPC command I'd make use of some DB or memcache variable to trigger this route i.e if(redis_cmd("srvN", "GET toggle_route", "r")){ $avp(signal) = $redis(r=>value); if($avp(signal) =~ 'true') { route(REMOTE_TEST); } } I used Redis, you can see if any RPC command can let you modify value of an AVP directly. For your second question check RPC commands uac.reg_refresh <http://www.kamailio.org/docs/modules/4.3.x/modules/uac.html#uac.r.uac.reg_r…> .

kamcmd & route[REMOTE_TEST]
by Marino Mileti 14 Jul '16

14 Jul '16

Hi guys, I've two question regarding rpc command. Is it possible to "execute" a specific route (for example my route[REMOTE_TEST]) using a rpc command by kamcmd? If not exist some other tricks to do this? Another question...regarding uac module... When Kamailio starts the UAC module makes a REGISTER according to database...and periodically refresh this registration. Is it possible to "force" a refresh with rpc command by kamcmd? Many thanks!

Modules How To ?
by Eng Hooda 14 Jul '16

14 Jul '16

Hello All, I just started using kamailio last month , using basic configuration I got from online tutorials I got it to work. Now I need to add functionality like offline messages delivery , searching lead me to msilo module , unfortunately I could not find a detailed tutorial of how to enable it and troubleshoot it's operation. All what I managed to find was the official technical documentation. https://www.kamailio.org/docs/modules/stable/modules/msilo.html It provides a list of parameters which has a default value , with no indication if the declaration of any of them is mandatory if the default values are kept intact. also there is a route code which I do not know if it was mandatory to copy to kamailio.cfg . Not to mention that the configuration file example contains lines that is already similar to what I already have , so which to keep and which to replace ? That was a case to apply to , but general answers (with msilo as an example) that apply to all modules is what I need just to avoid having to ask again if I needed to enable another module. Or may be there is something out there that I need to read first. system details : {(OS:Debian8 i386),(Kamailio4.4 with mySQL , UDP only)} Thank you all in advance. Best Regards, Eng Hooda

is_direction / $fti / $tti not working possible
by Nathan Angelacos 13 Jul '16

13 Jul '16

I'm missing something obvious here, throwing this out to get a couple extra sets of eyeballs on it. I can't get rr modules is_direction() or the $fti / $tti pv's to work in 4.3.x or 4.4.x Relevant parts of the config: loadmodule "rr.so" modparam ("rr", "enable_full_lr", 1) modparam ("rr", "append_fromtag", 1) ... route { xlog ("L_INFO", "$rm: $fu -> $ru"); record_route (); if (has_totag ()) { xlog ("L_INFO", "Before Loose route: fti: $fti tti: $tti ci: $ci"); if (loose_route ()) { if (is_direction ("downstream")) { xlog ("L_INFO", "in-dialog $rm request from caller to callee"); } else { xlog ("L_INFO", "in-dialog $rm request from callee to caller"); } xlog ("L_INFO", "After Loose route: fti: $fti tti: $tti ci: $ci"); } } if (! t_relay ()) { sl_reply_error (); } } ---- Bob and Alice are hard phones, with kamailio + dbaliases in the middle. Alice calls Bob, then Bob (the callee) sends the BYE ---- Syslog: 01. INVITE: sip:alice@kamailio.org -> sip:bob@kamailio.org:5060 02. Alias lookup returned <sip:bob@biloxi.com> , sending on 03. ACK: sip:alice@kamailio.org -> sip:bob@biloxi.com 04. Before Loose route: fti: 707601862 tti: 45686ADF-10AAEB28 ci: 8744171(a)atlanta.com 05. in-dialog ACK request from caller to callee 06. After Loose route: fti: 707601862 tti: 45686ADF-10AAEB28 ci: 8744171(a)atlanta.com 07. BYE: sip:bob@kamailio.org -> sip:alice@atlanta.com:5066 08. Before Loose route: fti: 45686ADF-10AAEB28 tti: 707601862 ci: 8744171(a)atlanta.com 09. in-dialog BYE request from caller to callee 10. After Loose route: fti: 45686ADF-10AAEB28 tti: 707601862 ci: 8744171(a)atlanta.com Using the above config, is_direction always returns "caller", even when bob is sending the message. Looking at a packet capture: 01. Kamailio Sent: Record-Route: <sip:kamailio.org;lr=on;ftag=707601862> <on the 200 ok from Bob> Kamailio Received: Record-Route: <sip:kamailio.org;lr=on;ftag=707601862> Kamailio Sent: Record-Route: <sip:kamailio.org;lr=on;ftag=707601862> 07. Kamailio Received: Route: <sip:kamailio.org;lr=on;ftag=707601862> Kamailio Sent: Record-Route: <sip:kamailio.org;lr=on;ftag=45686ADF-10AAEB28> I expect $fti to be wrong before the loose_route (line 08); but lines 09 and 10 are wrong. I'm obviously missing something trivial here. Any ideas what I should check next? Thanks!

Kamailio know which Interface Packet would route out
by SamyGo 13 Jul '16

13 Jul '16

Hi, Question: Is there a function in kamailio to get the interface/listen IP kamailio would use to route a packet out for a domain / ip ? Example: $avp(interface_ip) = find_interface_for_request("192.168.12.123"); And it gives me the Kamailio's Listen address that would be used for sending call out to this IP/Domain ! I've a weird situation where a multi-homed kamailio with about 7 different interfaces needs to send call out, I've so many RTProxy instances to engage but I can't decide which instance to engage since I do not know which Interface the Packet would route out from. Regards, Sammy

Re: [SR-Users] shm_malloc
by Daniel-Constantin Mierla 13 Jul '16

13 Jul '16

Hello, I don't expect to be very hard to extract the shm management code from kamailio. It is inside the subfolder mem/ . Then, there should be some dependecies that you need to get out from the core, coming in my mind is locking (mutexes). Maybe atomic operations (not remembering by heart if some counters are kept for memory management) and few other bits. It should work without crash, you just need to get it initialized as kamailio does it in it's main function.

Determining if request is from a local domain
by Shane Harrison 13 Jul '16

13 Jul '16

Hi all, >From previous posts my understanding is that RURI's are matched against reverse DNS lookup of listen addresses and aliases set via the "alias=" parameter in the config file (assuming the domain module isn't being used). However I am having difficulty in getting this to work. From looking at the code and the log file, it appears to me as if the alias isn't making it into the list of hosts that is checked against for some reason.

Video conferencing with Kamailio
by Jay Li 12 Jul '16

12 Jul '16

Dear All, I'm curious if anybody has set up an infrastructure for video conferencing utilizing Kamailio as a proxy (like NAT support and so so). I found a kind of old tutorial "Run you own Skype-like service in less than one hour" kamailio:skype-like-service-in-less-than-one-hour [Asipto - SIP and VoIP Knowledge Base Site] written in 2013 on Kamailio 3.1. I wonder if this feature has been further developed in later releases. I know Kamailio is more often used as a SIP proxy, but somehow I got the impression that Kamailio supports WebRTC, so I wonder if it's possible to implement a many to many video conferencing infrastructure using Kamailio. If the answer is yes, how's the performance or the bottleneck I should pay more attention to (maybe bandwidth for video traffic, especially with NAT? ) Anyway I'm a newbie to both Kamailio and video conference, so any suggestion/discussion is appreciated. Thanks. Regards,Jay

destination ip address
by Péter Barabás 12 Jul '16

12 Jul '16

Hi All, i need to store some information in routing_logic script into database with useing SQLOPS module. I made a custom table and store such data like source and destination username, domain, ip address and port. It works fine for almost every parameter except destination IP address and port. I want to ask what is the correct way to determine the destination IP address and port of a user for a MESSAGE, INVITE or BYE message? The $Ri and $Rp is not the correct ones. Thanks.

getting the local 408 response
by Jayesh Nambiar 12 Jul '16

12 Jul '16

Hi, I'm looking to catch the local 408 response generated by kamailio after the fr_timer strikes in. I was assuming to get it in the sl:local-request, but I dont see it in my log messages. I can catch responses like a 200 for register or a 487 for a message who's transaction is not yet created. Any proper way on how do I get to know when kamailio generates a local 408? I'm on the master branch (commit: 54562b873c2c3d0a04f0587e7706188a3eb19a74). Thanks, - Jayesh

Calculating time differences
by Sebastian Damm 11 Jul '16

11 Jul '16

Hi, we are suspending a transaction at one place in our route and resume it later. I want to log the time difference between suspending and resuming. I thought I could do it with saving $TV(Sn), but apparently I can't. Kamailio says, it can't convert the saved value into integer. This true, of course. I was searching for a transformation function converting this string into float, but there is none. Is there any way to calculate a time difference other than to live with seconds-only precision? Best Regards, Sebastian

Kamailio WEBRTC questions/ confusions
by Zaka 10 Jul '16

10 Jul '16

Dear List: I wonder if this has been asked before. Please ignore or point to the appropriate source, if needed. Simply, I have little experience with SIP servlets implementing WEBRTC/ Click2Call etc... Considering a Call Centre scenario offering a WEBRTC solution. Following are the confusions regarding requirements: 1: A Kamailio Box (running WEBSOCKET.config) 2: Customer will use web browser (websocket compatible of course) and enter address of the KAMAILIO Box or we shall need another KAMAILIO to statelessly forward the call to next available operator using Hunt Group or similar scheme? 3: If we don't plan to implement TLS/ MSRP (disabling these in the config file should be suffice?) 4: Last, but not the least, how will the users send request for login from browser? (assuming they have accounts created in the DB on Kamailio Box running WEBSOCKET supported KAMAILIO) With anticipatory thanks & regards, Zaka

re-INVITE on IP Change with Outbound
by Colin Morelli 08 Jul '16

08 Jul '16

Hey list, So I'm using the outbound module to ensure subsequent requests are delivered over an active TCP connection established by the mobile client. However, now I'm trying to add support for automatically responding to network changes (WiFi <-> LTE), and it's creating problems. Primarily, the issue is that when the device sends a re-INVITE for the call, its Route: header includes a flow-token corresponding to its *old* socket connection. Because the new request doesn't have the same source IP/port as the old connection did Kamailio thinks that the next route hop it needs to take is to pass the request over to the connection identified by the flow token. So it actually tries to re-open a TCP connection back out to the client even though I'm making the re-invite because that old transport is no longer valid. Does anyone have a recommended way of handling this case? I can add another header/param to the route header and manually remove it. Before loose_routing. Essentially, on in-dialog INVITE requests I want to ignore the outbound token on the originating side but I can't seem to find a way to do that without re-writing the header before loose_routing. Best, Colin

shtinc throws readonly error
by Sebastian Damm 08 Jul '16

08 Jul '16

Hi, I'm trying to use this line in one route: $shtinc(pushedUsers=>$avp(s:authuser)); However, when checking the syntax of this file, Kamailio says: 0(609) : <core> [cfg.y:3365]: yyerror_at(): parse error in config file /etc/kamailio/kamailio_sip_proxy.cfg, line 3304, column 2-39: read only pvar in assignment left side According to the pseudo vars documentation, I should be able to use it like that. Can someone tell me what I am missing? Best Regards, Sebastian

tsilo ts_append problem
by gmele 08 Jul '16

08 Jul '16

Hello, we are using tsilo to achieve mobile push notification in kamailio. In tsilo module documentation, ts_append() function is used with the pseudo variable “$tU” holding the username of the to-uri. Our config looks like : route[PUSHJOIN] { $var(hjoin) = 0; lock("$tu"); $var(hjoin) = $sht(vtp=>join::$tu); $var(hstored) = $sht(vtp=>stored::$tu); $sht(vtp=>join::$tu) = $null; unlock("$tu"); if ($var(hjoin)==0) { if ($var(hstored)) { ts_append("location", "$tU"); } return; } $var(id_index) = $(var(hjoin){s.select,0,:}{s.int}); $var(id_label) = $(var(hjoin){s.select,1,:}{s.int}); t_continue("$var(id_index)", "$var(id_label)", "INVRESUME"); } In ts_append() function code, ts_check_uri() is called on a variable holding a username and not a URI causing the failure of the function ts_check_uri() and resulting in ts_append() to exit. The following line is displayed in the log: [tsilo.c:205]: ts_check_uri(): bad uri [giovanni.mele]. The function ts_store() stores in the R-URI field the username and not the request URI. route[RELAY] { # enable additional event routes for forwarded requests # - serial forking, RTP relaying handling, a.s.o. 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"); } if (!t_relay(PROXY_IP, PROXY_PORT)) { sl_reply_error(); } if (is_method("INVITE")) { ts_store(); $sht(vtp=>stored::$tu) = 1; route(SENDPUSH); } exit; } route[INVRESUME] { statsd_gauge("SIPRegistrar.InviteResumed", "+1"); lookup("location"); t_relay(PROXY_IP, PROXY_PORT); ts_store(); $sht(vtp=>stored::$tu) = 1; } With the command “kamcmd ts.dump” we can see the following lines: R-URIs: { R-URI: giovanni.mele Hash: 74014921 Transactions: { Transaction: { Tindex: 63704 Tlabel: 2105932514 } } } If we try to use the ts_append() function with the pseudo variable “$tu” holding the full to-uri address, there is no error returned by ts_check_uri() (as this is called on a correct URI) but the transaction corresponding to the to-uri cannot be found (maybe because the R-URI stored by ts_store() is the username and not the full R-URI). How can we make things work ? By storing the full R-URI with ts_store() ? Thx for your help Giovanni -- View this message in context: http://sip-router.1086192.n5.nabble.com/tsilo-ts-append-problem-tp150184.ht… Sent from the Users mailing list archive at Nabble.com.

4.4.1: Only first UDP Listener is producing log messages
by Sebastian Damm 08 Jul '16

08 Jul '16

Hi, I upgraded one of our systems today to 4.4.1. And when checking whether everything is okay, I noticed, that only the first UDP listener (from kamcmd core.ps) is actually sending lines to the log. The only other logs I see are from usrloc timer worker. kamcmd> core.ps 10737 main process - attendant 10740 udp receiver child=0 sock=172.20.40.5:5060 10741 udp receiver child=1 sock=172.20.40.5:5060 10742 udp receiver child=2 sock=172.20.40.5:5060 10743 udp receiver child=3 sock=172.20.40.5:5060 We are sending quite a lot of information via xlog("L_NOTICE", "foo"); to syslog, but the only lines I see are from PID 10740. Kamailio works fine otherwise, handling all requests, the usrloc entries didn't drop, and customers don't complain. So I think it's only a logging issue. There are about 50k registrations on the machine and more than 10 Mbit of traffic. When I downgrade to 4.3.5, I get output from all listeners again. Has there been any change between 4.3 and 4.4 regarding logging? The upgrade document says nothing about this. Best Regards, Sebastian
