Hello all, I'm using Kamailio as a registrar and i have an endpoint that sometimes sends a REGISTER method with a To-Tag when refreshing its regist. My code on this proxy shares many similarities with the default kamailio.cfg configuration file. On that occasion Kamailio answers with a 404 - Not Here since it treats it as a in-dialog request which fails the loose_route check. Why would a CPE send a REGISTER with a To-Tag? Why is a REGISTER with a To-Tag rejected by Kamailio when it could otherwise be a successful REGISTER? Is this behaviour noncompliant with the SIP protocol? I thought about making an exception in the code and having this register following the same path as a register without to-tag, but i don't know if that is unsafe and/or noncompliant with the protocol. Best Regards,

potential PRACK related topos bug

by Juha Heinanen

In case of topology: A - P1 - P2 - P1 - B is the idea to use in P1 context "in" when initial request comes to P1 from A or B and context "out" when initial request comes to P1 from P2? Does context need to be set in replies too? If so, is reply context the same as the corresponding request context? And finally, does context need to be set for in-dialog requests/replies the same way as for initial requests? -- Juha

how to turn off memory debug messages?

by Juha Heinanen

In config file I have: debug=2 mem_summary=0 Still I get 3400+ memory related syslog message when Kamailio terminates due to sqlops not been able to connect to mysql server. According to core cookbook, memdbg and memlog should not be active when their values are greater than debug value (they default to 3) and mem_summary=0 should disable printing of memory debugging info. What is it that I'm still missing? -- Juha

[ANNOUNCE]: sipnagios, a Nagios Plugin to check Call Quality in SIP VoIP (compatible with checkmk, etc)

by Giovanni Maruzzelli

Hello fellow VoIPers and RTCers, on GitHub there is an early release of sipnagios, opensource. check it out: https://github.com/gmaruzz/sipnagios sipnagios is a Nagios Plugin to check Call Quality in SIP VoIP (compatible with checkmk, etc) sipnagios implements the Nagios plugin API for monitoring and performance data.sipnagios.c is a modification of the original siprtp.c sample in pjproject distribution. Supposedly, it works on Linux, Windows, and anywhere you can compile pjproject on.It makes a call, checks all the various resulting values (mos, rtt, pdd, tta, jitter, packet loss, bytes and packets transferred, and so on). It verifies these values are included into acceptable, warning, or critical ranges.If the call has gone well, sipnagios print performance data for Nagios graphs, and returns 0.If the call fails, or if its measured values are not inside acceptable ranges, it exits with Nagios conventional WARNING or CRITICAL values. mos calculation is scraped from Julien Chavanton work (VoIP Patrol, on GitHub too) I can't even understand :) (merci Julien!) Enjoy! -giovanni -- Sincerely, Giovanni Maruzzelli OpenTelecom.IT cell: +39 347 266 56 18

Branch 5.5 has been created

by Daniel-Constantin Mierla

Hello, the branch 5.5 has been created, to be used for releasing v5.5.x series. To check out this branch, the following commands can be used: git clone https://github.com/kamailio/kamailio kamailio-5.5 cd kamailio-5.5 git checkout -b 5.5 origin/5.5 Pushing commits in this branch: git push origin 5.5:5.5 Note that 5.5 is an official stable branch, so only bug fixes, missing kemi exports (discuss on sr-dev if not sure) or improvements to documentation or helper tools can be pushed to this branch. As usual, if there is a bug fixed, commit and push first to master branch and then cherry pick to 5.5 branch: git cherry-pick -x COMMITID In few weeks, the first release from branch 5.5 will be out, respectively Kamailio v5.5.0.

Development is open for future release of v5.6.x series

by Daniel-Constantin Mierla

Hello, the branch 5.5 was created, therefore the master branch is open for adding new features, to be part of future release series v5.6.x (or whatever version is decided for next series). Any bug fix committed to master that applies to 5.5.x or older stable branches should be backported as usual with "git cherry-pick -x ..." to appropriate branches like 5.5 or 5.4. Expect that v5.5.0 will be released in a few weeks from now. Based on the workflow used during the past years, the next future release v5.6.0 should be out after another 6-10 months of development, plus 1-2 months of testing, so sometime by end of 2021 or in the first part of 2022.

Reminding again about private/direct emails from mailing lists discussions

by Daniel-Constantin Mierla

A lot of emails are still sent directly to me after a discussion started on public mailing lists (subject with mailing lists prefix, but the sender header is not the mailing list daemon), I would like to remind that, at least in my case, writing emails directly without cc-ing the mailing list is highly not recommended and there is practically 0 chance to get an answer from myself. The rule is also suggested in the mailing lists presentation page: - https://www.kamailio.org/w/mailing-lists/ Unless I asked explicitly for a private email with some specific details, the message will not be noticed in decent time 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. Therefore if you wrote me and expect a response, re-send the message to the appropriate public mailing list. Checking and answering the messages on Kamailio mailing lists are among the top of priorities on my daily activity, so it is high chance you get the response faster when you write there. Note that you can always mask sensitive data (e.g., replace passwords, IP addresses) before sending logs or config file. There are several common sense as well as technical reasons for keeping the discussion on public mailing lists. 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. There might be many unanswered as well, people are travelling 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 a reply instantly, or this application not good or 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, have appropriate expectation and behavior.

Branching 5.5 on git repo for 5.5.x releases

by Daniel-Constantin Mierla

Hello, since freezing the development for 5.5 series, I did quite a lot of code analyzing with a bunch of tools as well as run various tests, no major issue being in my list at this moment, therefore I think we can plan branching 5.5 on git repo in the near future. If there is no other suggestion or argument against it, I propose to create the branch 5.5 on Thursday next week (April 22, 2021). After that, master branch will be open for new features (to become part of 5.6 or what ever version will be decided to be next), testing will continue for branch 5.5 for another 1-2 weeks, then we will release 5.5.0 as first stable version in the 5.5.x series.
