Kamailio fails to start when tls module parameter 'config' contains a folder name
by Leonid Fainshtein 02 Oct '20

02 Oct '20

Hi, I am using Kamailio 5.4.1 installed from the packages on Ubuntu 18.04. When I define 'modparam("tls", "config", "<folder>")', Kamailio fails to start: ERROR: tls [tls_config.c:418]: tls_load_config(): cannot make tmp file configrcCczj ERROR: <core> [core/sr_module.c:849]: init_mod(): Error while initializing module tls (/usr/lib/x86_64-linux-gnu/kamailio/modules/tls.so) I checked the tls_load_config() function and found that when a folder is defined in the 'config' parameter, the function tries to open a temporary file in the working directory. I believe that the working directory at that point is the folder where Kamailio was started: /usr/sbin. I succeeded to launch Kamailio in two ways: Method 1: copy 'kamailio' to /tmp and modify kamalio.service accordingly. This experiment result made me think that the working folder is the folder where kamailio is started. Method 2: add Kamailio command line parameter "-w /tmp" (I also tried to define the Systemd 'WorkingDirectory' parameter but it didn't have any effect.) I think that the ultimate solution for this problem is to modify the tls_load_config() function in such a way that it will open the temporary file in a folder that is intended for the temporary files. For example, the /tmp folder in Linux and *BSD systems. I guess that /tmp is a good place in MacOS as well. Best regards, Leonid Fainshtein

TOPOS issue
by David Villasmil 01 Oct '20

01 Oct '20

Hello guys, I have this scenario where I have an ongoing transaction. I receive a 180 (non 100rel) with some to_tag, which i forward back to the caller. Then I receive an 183 (100rel) which is forwarded back to the caller, who in turn PRACKs it. It is then that Kamailio (apparently) can't match that transaction internally and replies to the caller (the one PRACKing the 183 (100rel)), with 493 FORBIDDEN. I'm attaching a trace flow. (Kamailio is 10.255.0.1) you need to open the email really wide to see it properly. Anyone ever encountered this?

XHTTP_Prom syntax error with usrloc in Kamailio 5.3
by Tim Unkrig 30 Sep '20

30 Sep '20

Hello hello, I would like to monitor our production kamailio cluster (5.3) with prometheus and I was in the beginning so happy to spot the xhhtp_prom module. But when we enabled it, the output was in view of prometheus malformed in combination with the usrloc module, we got the following output: kamailio_usrloc_location-contacts 0 1597934423943 kamailio_usrloc_location-expires 0 1597934423943 kamailio_usrloc_location-users 0 1597934423943 Prometheus only accepts “_” instead of “-“. So unfortunately I get "strconv.ParseFloat: parsing "-contacts": invalid syntax” on the prometheus primary node, when I activated the scraper. This has been issued in the master branch of kamailio with a sanatize function for that problem. But I would like to avoid compiling modules by myself, because this can be messy from time to time. That´s why my question, is there maybe another way of fixing this? I really appreciate any comments here and thanks for your time, Tim Unkrig

xavu methods equivalent to that of xavp (e.g. xavp_get_child)
by Chaigneau, Nicolas 30 Sep '20

30 Sep '20

Using xavu (now that they have been fixed) in a custom C module, I've noticed that the following methods do not exist: xavu_get_child xavu_get_child_with_ival xavu_get_child_with_sval xavu_serialize_fields Though they are not strictly necessary, it could be useful to add them to Kamailio core. (Possibly with code refactoring, to avoid duplicating whole functions ?) What do you think? Regards, Nicolas.

Computing a time difference when handling a stateless SIP request
by Chaigneau, Nicolas 30 Sep '20

30 Sep '20

Hello, New to Kamailio, first post on this ML. I'll probably ask dumb questions, please bear with me :) Here goes the first one. I would like to compute a time difference (with microseconds precision) when handling a stateless SIP request. I looked into the core functions and modules but did not find anything suitable. Before I start implementing this by myself, I'd like to know if there's a simpler way. Thanks for your help! Regards, Nicolas.

websocket transport protocol in Record-Route header
by Juha Heinanen 29 Sep '20

29 Sep '20

No matter if UA uses ws or wss to connect to Kamailio, when K routes INVITE from this UA and record_route() is called, K always adds ;transport=ws parameter to Record-Route URI, for example, Record-Route: <sip:192.168.43.83:7998;transport=ws;r2=on;lr> In this test, Kamailio is listening on that port like this: # SIP over WebSocket listen=tls:192.168.43.83:7998 Why doesn't K in this case add ;transport=wss to the R-R URI? -- Juha

A possibility to disable the topology hiding for some destinations.
by Leonid Fainshtein 29 Sep '20

29 Sep '20

Hi, The 'topos' module has a very useful "event_route[topos:msg-sending]" option that allows very easily to disable topology hiding for ITSPs that requires the real data in the Contact header field. It looks like the feature is not supported in the 'topoh' module (ref. https://kamailio.org/docs/modules/5.4.x/modules/topoh.html). The available 'event_route[topoh:msg-outgoing]' option requires defining the remote server IP address (or a list of addresses in some cases) that is not always convenient. Is there a chance that "event_route[topoh:msg-sending]" will be added? Best regards, Leonid Fainshtein

Rewrite BYE to Cancel
by Lars Olsson 29 Sep '20

29 Sep '20

hi, I have a Kamailio setup infront of a SIP system that do not handle cancellation of a INVITE correctly. The system sends out a BYE request instead of a Cancel request on non connected dialogs. I am trying to find a way to let Kamailio "translate" the BYE request to a Cancel reqeust for the ongoing INVITE dialog. Alternative if SEMS b2bua can do it, but currently it replies: "not sip-relaying BYE in not connected dlg", and I have not found any obvious way to rewrite it there. Any thoughts. I can not change the behavior of the remote system. Best Regards, Lars

Dialog - timeout for dlg with CallID
by Ilie Soltanici 28 Sep '20

28 Sep '20

Hello, I'm trying to get CDR working in Kamailio by using the acc and dialog modules. Everything seemed to be working fine - until i noticed that for some of the calls the call duration is 0, even if that call has been successfully established and duration was for about a few minutes. In the Kamailio logs I'm getting such errors: WARNING: dialog [dlg_handlers.c:1649]: dlg_ontimeout(): timeout for dlg with CallID '304bad142b50bb3a7a117816439ea3d5' and tags 'as3adde5c7' '7d28152f-e0e3-4bcf-9d5c-21c3723b95c5' WARNING: acc [acc_cdr.c:230]: db_write_cdr(): fallback to dlg_only search because of message doesn't exist. This error I'm getting at about 2 min after the ACK message for 200 OK. I'm not sure that this is related to the dialog timeout, but below you can see the related configuration for the dialog module: modparam("dialog", "default_timeout", 10800) # 3 hours modparam("dialog", "early_timeout", 180) modparam("dialog", "noack_timeout", 90) Unfortunately, I'm not able to reproduce this issue, as that's happening randomly and just a few times per day. On the SIP Level i didn't notice any strange issues. Any ideas why is that happening? Thank you.

Lua kemi-test-suite now availble from luaRocks
by Yuriy Gorlichenko 28 Sep '20

28 Sep '20

Hello Kamailians! I'm glad to announce some updates about the Lua Kemi-test-suite which has been presented on KamailioWorld online 2020 conference https://github.com/ovoshlook/kemi-lua-test-suite There are some important updates that I hope will make your life easier if you use Lua KEMI. - Now (finally!) it is available via LuaRocks. So it is easy to go for now. No more manual source downloads! (this is the main reason I'm writing this message ). - More modules and some core functions have been mocked. It is still a lot of jobs that have to be done but the amount of available mocks is growing. - Added CRASH_PROTECTION functionality. So for now there is a mechanism which is checks if you calling a function with an incorrect amount of params ( see README ). - Extended mocking engine: now it is possible to mock any functions of KSR or third-party modules/libraries: for example, Redis, MySQL, or other connectors calls. P.S. suite still on development and changes from time to time, but published versions are stable and ready to use. P.P.S. Warm welcome to contributors.

Linphone push notifications (iOS) and kamailio
by Jan Rozhon 26 Sep '20

26 Sep '20

Hi, I know this is kind of a wrong forum for this question, but I have got no answer from linphone forum so I am trying my luck here. I have kamailio with pretty much the default config with slight modification enabling me the push notifications for iOS (via curl) and late forking (t_suspend, t_continue). But my linphone on iOS although gets awaken does not present me with the call I am trying to establish. Did anyone of you guys experimented with similar setup? If so, to what degree were you successful and can you share some insights especially on the format of push notification where I suspect my problem to be rooted? Thanks in advance and once again, sorry if I am off-topic too much. Regards, Jan
