Request for Feedback on an Installation Script for Kamailio (from Source)
by BROU STEPHANE FABIEN 19 Dec '24

19 Dec '24

Dear Kamailio Community, I hope this message finds you well. I have recently developed an install.sh script aimed at simplifying the process of installing Kamailio directly from source. My goal is to streamline the installation process while adhering to best practices for Kamailio deployment. I would greatly appreciate your feedback, suggestions, or any corrections to help improve the script’s robustness and ensure it aligns with the community’s standards. You can find the script in my GitHub repository: https://github.com/AL-CALL-LLC/KamailioBuilder.git Feel free to test it, share your thoughts, or open issues on GitHub for any recommendations or areas that need refinement. Thank you in advance for your time and valuable expertise. I am more than happy to provide further details or engage in discussions if needed. Best regards, Fabien Brou Developer

Multiple Branches and 3xx Status Codes
by Christian Berger 17 Dec '24

17 Dec '24

Hi, we have the following situation: Multiple UAs are subscribed to the proxy and get INVITEd via parallel forking. Now one of the UAs sends us a 302 status, we would like to handle this like a failure. So we'd like to CANCEL all the other branches, and forward the 302 status to the original INVITE. We have tried t_reply("302", "$T(reply_reason)") in the response, which almost solves this, however we cannot pass the required headers form the 302 response in it. BTW, could there have been a change in the default behavior of Kamailio? We think it used to "just work" in the past. Thank you very much Christian Berger -- Christian Berger - berger(a)sipgate.de Telefon: +49 (0)211-63 55 55-0 Telefax: +49 (0)211-63 55 55-22 sipgate GmbH - Gladbacher Str. 74 - 40219 Düsseldorf HRB Düsseldorf 39841 - Geschäftsführer: Thilo Salmon, Tim Mois Steuernummer: 106/5724/7147, Umsatzsteuer-ID: DE219349391 www.sipgate.de - www.sipgate.co.uk

Development for v6.0.x is frozen
by Daniel-Constantin Mierla 17 Dec '24

17 Dec '24

Hello, the formal notification that the development for the next major version 6.0.0 is now frozen. The focus has to be on testing the master branch. Also, the master branch should not get commits with new features till the branch 6.0 is created, expected to happen in 2-4 weeks, a matter of how testing goes on. Meanwhile, the commits with new features in the C code can be pushed to personal branches, new pull requests can still be done, but they will be merged after branching 6.0. Can still be done commits with documentation improvements, enhancements to related tools (e.g., kamctl, kamcmd), merging exiting pull requests at this moment, exporting missing KEMI functions and completing the functionality of the new modules added for 6.0. Once the branch 6.0 is created, new features can be pushed again to master branch as usual. From that moment, the v6.0.0 should be out very soon, time used for further testing but also preparing the release of packages. If someone is not sure if a commit brings a new feature, just make a pull request and it can be discussed there on github portal or via sr-dev mailing list. A summary of what is new in upcoming 6.0 is going to be built at: * https://www.kamailio.org/wikidocs/features/new-in-6.0.x/ Upgrade guidelines will be collected at: * https://www.kamailio.org/wikidocs/install/upgrade/5.8.x-to-6.0.0/ Everyone is more than welcome to contribute to the above wiki pages, especially to the upgrade guidelines, to help everyone else during the migration process from v5.8.x to 6.0.x.

Freezing development for 6.0.x series
by Daniel-Constantin Mierla 16 Dec '24

16 Dec '24

Hello, I propose to aim freezing the development for 6.0.x series at the end of the 16th of December 2024 (Monday). New features that one wants to get in this release series have to be pushed to git repository or pull requests made for them. Afterwards usually follows a 4-6 weeks of testing till the first release 6.0.0. Unfreezing will happen earlier, after the first weeks of testing when the 6.0 branch will be created.

ims_diameter_server: $diameter_response PV is null in the event_route[diameter:response]
by Grotti, Daniel 15 Dec '24

15 Dec '24

Hi list, I'm using kamailio 5.8 and playing with the ims_diameter_server module, by sending an async diameter request and trying to catch the reponse. Following the documentation, I'm sending the request with: route[SEND_ACR] { route(PREPARE_ACR); diameter_request_async("3", "271", "$var(json_acr)"); } route[PREPARE_ACR] { # here I build the AVP list in JSON $var(json_acr) = "[{"avpCode":277,"vendorId":0,"Flags":64,"int32":0},{...},{...}]"; } event_route[diameter:response] { xlog("Reply to diameter request is: '$diameter_response'\n"); } The ACR request is successfully sent and the the server is replying with ACA. The list of AVP are properly parsed, but when I enter the event_route to print the response, I get the $diameter_response = 'null': 2024-12-11T10:52:39.192951872+00:00 stderr F 11(19) DEBUG: cdp [worker.c:374]: worker_process(): worker_process(): [2] got task Q(2/2) 2024-12-11T10:52:39.193026280+00:00 stderr F 11(19) DEBUG: ims_diameter_server [avp_helper.c:60]: avp2json(): AVP((nil) < 0x7ff827633810 >0x7ff8276338c0);code=263,flags=40; 2024-12-11T10:52:39.193026280+00:00 stderr F DataType=1;VendorID=0;DataLen=52; 2024-12-11T10:52:39.193026280+00:00 stderr F 11(19) DEBUG: ims_diameter_server [avp_helper.c:60]: avp2json(): AVP(0x7ff827633810 < 0x7ff8276338c0 >0x7ff827633970);code=268,flags=40; 2024-12-11T10:52:39.193026280+00:00 stderr F DataType=3;VendorID=0;DataLen=4; 2024-12-11T10:52:39.193026280+00:00 stderr F 11(19) DEBUG: ims_diameter_server [avp_helper.c:60]: avp2json(): AVP(0x7ff8276338c0 < 0x7ff827633970 >0x7ff827633a20);code=264,flags=40; 2024-12-11T10:52:39.193026280+00:00 stderr F DataType=1;VendorID=0;DataLen=37; 2024-12-11T10:52:39.193026280+00:00 stderr F 11(19) DEBUG: ims_diameter_server [avp_helper.c:60]: avp2json(): AVP(0x7ff827633970 < 0x7ff827633a20 >0x7ff8276340b0);code=296,flags=40; 2024-12-11T10:52:39.193026280+00:00 stderr F DataType=1;VendorID=0;DataLen=33; 2024-12-11T10:52:39.193124627+00:00 stderr F 11(19) DEBUG: ims_diameter_server [avp_helper.c:60]: avp2json(): AVP(0x7ff827633a20 < 0x7ff8276340b0 >0x7ff827634160);code=259,flags=40; 2024-12-11T10:52:39.193124627+00:00 stderr F DataType=0;VendorID=0;DataLen=4; 2024-12-11T10:52:39.193286132+00:00 stderr F 11(19) DEBUG: ims_diameter_server [avp_helper.c:60]: avp2json(): AVP(0x7ff8276340b0 < 0x7ff827634160 >0x7ff827634210);code=480,flags=40; 2024-12-11T10:52:39.193286132+00:00 stderr F DataType=0;VendorID=0;DataLen=4; 2024-12-11T10:52:39.193286132+00:00 stderr F 11(19) DEBUG: ims_diameter_server [avp_helper.c:60]: avp2json(): AVP(0x7ff827634160 < 0x7ff827634210 >0x7ff8276342c0);code=485,flags=40; 2024-12-11T10:52:39.193286132+00:00 stderr F DataType=0;VendorID=0;DataLen=4; 2024-12-11T10:52:39.193286132+00:00 stderr F 11(19) DEBUG: ims_diameter_server [avp_helper.c:60]: avp2json(): AVP(0x7ff827634210 < 0x7ff8276342c0 >(nil));code=85,flags=40; 2024-12-11T10:52:39.193286132+00:00 stderr F DataType=0;VendorID=0;DataLen=4; 2024-12-11T10:52:39.193612877+00:00 stderr F 11(19) INFO: <script>: [event_route]: Reply to diameter request is: '<null>' Is there something I miss to set/configure?

How to remove rr param on a reply?
by Benoît Panizzon 13 Dec '24

13 Dec '24

Hi Is there a way to remove an param from the top most rr header? I add a rr param towards the B CPE to store some information which is sent back on the rr header of the reply from B. So far this is what is intended and I also get this param in subsequent route headers from messages created by B and as the route header are remove towards A, this works fine. Unfortunately, in a case of a reply, the parameter is passed to A which is then sending back the param in the route header which would make it somehow complicated to figure out which side sent that parameter. I'm only interested if sent from B. So I wonder, is there a way to delete a rr param on replies to make sure I don't get it back in the ACK to the reply? -- Mit freundlichen Grüssen -Benoît Panizzon- @ HomeOffice und normal erreichbar -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________

registrar / usrloc / tm => 'load balanced' serial forking?
by Benoit Panizzon 13 Dec '24

13 Dec '24

Hi List With the dispatcher module, you can use different ways of load balanced and weighted serial or parallel forking. Is there a corresponding way to achieve load balanced serial forking to a destination set loaded from registered locations? Use case: Customer with a high availability set-up has two redundant PBX registered to the same AoR. Calls can not be sent in parallel as this would generate two concurrent calls to the end device but call should be distributed evenly between the two contacts registered with that AoR.

HTTP_CLIENT timeout
by Sergio Charrua 13 Dec '24

13 Dec '24

Hello all! For a STSH project, kamailio is making HTTP requests to a middleware (REST API) using HTTP_CLIENT module. I have set the parameter "timeout" to 2 second, but this increases PDD to too high levels, so I have set it to 1 second. Problem is that 1sec is also too high! The parameter only accepts integer values, so no way to set this to 0.5sec. I thought of having a way for kamailio to be aware that HTTP node #1 is down, so next request it will use HTTP node #2 instead. And once in a while, say, every 60 seconds, kamailio would check status of HTTP node #1 and, if OK, then it will switch back to HTTP node #1 and failover to node #2 when required. The HTTP_CLIENT, as far as I know, doesn't do that. So the question is: what would be the best approach to have this feature on Kamailio? i thought about using HTable and have a flag with value of the HTTP connection to use by default. At worst, only the 1st failover request would take 1 or 2 seconds to timeout....then the subsequent HTTP requests would use node #2. Any ideas? Atenciosamente / Kind Regards / Cordialement / Un saludo, *Sérgio Charrua*
