How to keep SIP messages small, possibly below fragmentation limit?
by Benoît Panizzon 26 Feb '24

26 Feb '24

Hi In the process of getting rid of our commercial B2Bua SBC and handling all clients directly via Kamailio... We have come across some (unfortunately many we have in use) CPE which have an issue with fragmented packets or which simply do not allocate enough memory to parse or create messages of a certain size. Their SIP stack just crashes with errors like 'message to large for send buffer' and similar. This affects messages with containing as little as 5 via and 4 record-route header and a couple of codec in the SDP. Is there a recipe for trying to keep packets as small as possible? I would like to avoid using the topos module as I issues with this module completely failing in certain situations. -- 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 ______________________________________________________

Development is open for future release of v5.9.x series
by Daniel-Constantin Mierla 23 Feb '24

23 Feb '24

Hello, the branch 5.8 was created, therefore the master branch is open for adding new features, to be part of future release series v5.9.x (or whatever version is decided for next series). Any bug fix committed to master that applies to 5.8.x or older stable branches should be backported as usual with "git cherry-pick -x ..." to appropriate branches like 5.8 or 5.7. Expect that v5.8.0 will be released in a few weeks from now. Based on the workflow used during the past years, the next future release v5.9.0 should be out after another 8-10 months of development, plus 1-2 months of testing, so sometime during the last part of 2024 or the beginning of 2025.

Branch 5.8 has been created
by Daniel-Constantin Mierla 23 Feb '24

23 Feb '24

Hello, the branch 5.8 has been created, to be used for releasing v5.8.x series. To check out this branch, the following commands can be used: git clone https://github.com/kamailio/kamailio kamailio-5.8 cd kamailio-5.8 git checkout -b 5.8 origin/5.8 Pushing commits in this branch: git push origin 5.8:5.8 Note that 5.8 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 5.8 branch: git cherry-pick -x COMMITID In few weeks, the first release from branch 5.8 will be out, respectively Kamailio v5.8.0.

Building Debian packages for further modules
by Christian Berger 22 Feb '24

22 Feb '24

Hi, for our workflow we build our own Debian packages for kamailio. We are currently trying and failing to create a package for the kafka modules. What we have tried so far: Adding the "Build-Depends:" entries for librdkafka-dev in debian/control Adding a "Package" in debian/control Adding kafka to the PACKAGE_GROUPS in debian/rules So far it seems to build the module and a package for it, but the package only contains metadata, but no .so file. We are currently running out of ideas. What else can we do?

Kemi questions
by Stefan-Cristian Mititelu 21 Feb '24

21 Feb '24

Hello, When writing kemi cfg (python in my case), is there any way to get rid of standard cfg shared variables and use kemi cfg variables instead? E.g. Instead of $shv(blabla) (in standard config) can I use some global python var called 'blabla'? Is it seen and shared by all kamailio processes? Or I still need to use KSR.pv.get/set("$shv(blabla)") ? Thank you, Stefan

by Henning Westerholt 20 Feb '24

20 Feb '24

Hello, just a question about the https://rpm.kamailio.org/ repository, especially regarding git master builds. It seems that the git master build there was updated last autumn. It would be great if it could be updated, now as we want to test for the coming release. Thank you, Henning Westerholt -- Henning Westerholt - https://skalatan.de/blog/ Kamailio services - https://gilawa.com<https://gilawa.com/>

dialog:event unknown and kemi callback error
by Duarte Rocha 20 Feb '24

20 Feb '24

Hello all, I'm currently developing some kamailio scripts with app_jsdt by migrating a proxy of mine from Kamailio routing script to Js. I've migrated some parts of my request_route and everything seems to be working fine. I am now trying to migrate my event routes to JS and I started with dialog. dialog parameters : modparam("dialog", "event_callback", "dialogEvent") Code : function dialogEvent(event) { KSR.info("Dialog event " + event + " in JS") } After this i try to make a call and in my logs i have : "Dialog event unknown in JS" "Dialog event dialog:start in JS" Is this normal behaviour that I should ignore and only try to process "start,end,failure" or is this a signal of something wrong in my code? I also have this error in my code : "sr_kemi_cbname_lookup_idx(): index 1 is out of range". Does that mean that i have a JS function that calls a missing function in kamailio script or the opposite? How can I identify the root cause? Thanks in advance, Cheers

Variable specific to branch reply?
by Benoit Panizzon 20 Feb '24

20 Feb '24

Hi List avp stacking is starting to drive me crazy... Somehow I don't understand what is going on in this situation: I have a main branch, and add two more branches with append_branch() I use a on_branch_route trigger: branch_route[BR_TO_CPE] { [Here, some code setting $var(needbh)] if ("yes" == $var(needbh)) { xlog("L_INFO", "$cfg(route): BR_idx: $T_branch_idx BACKHAUL: YES to $nh(u) \n"); add_rr_param(";rtp=yes"); record_route(); $avp(backhaul) = "yes"; $avp(nexthop) = $nh(u); rtpengine_manage($avp(rtp_to_cpe)); } else { xlog("L_INFO", "$cfg(route): BR_idx: $T_branch_idx BACKHAUL: NO to $nh(u) \n"); record_route(); $avp(backhaul) = "yes"; $avp(nexthop) = $nh(u); } } In the Logs, I see Branches Index 0,1,2 with the desired information. So I have 3 values stacked in the avp backhaul and nexthop, right? When I get a reply, I would like to determine if backhauling is required or not. onreply_route[MANAGE_REPLY] { xlog("L_INFO", "MANAGE_REPLY: for BR_idx: $T_branch_idx\n"); while ($(avp(nexthop)[$var(i)]) != $null) { xlog("L_INFO", "MANAGE_REPLY: DEBUG Branch: $T_branch_idx VAR IDX: $var(i) NH: $(avp(nexthop)[$var(i)]) \n"); $var(i) = $var(i) + 1; } } So on EVERY reply, I would expect to get three "DEBUG" lines as I stacked 3 AVP.. Bug I get only 2! Why I am missing one of the stacked AVP? (the last one as it looks like) Or is there any other way to access a arbitrary variable specific to a branch on the reply to that branch? PS: I don't need $avp(nexthop). It's just an easy way to make sure I get the correct avp index for the branch I am interested in.
