Using a second Perl library
by David Cunningham 04 May '23

04 May '23

Hello, We are using a product which already uses the "app_perl" module and sets the "filename" parameter to its own Perl library. However, we want to add more Perl code without having to modify that product's library. Does anyone know of a way to do this? To have Kamailio use Perl code from two different places? I guess in the worst case scenario we could use "app_python3", and have some Python code call subprocess.run() on the Perl code. Thanks very much, -- David Cunningham, Voisonics Limited http://voisonics.com/ USA: +1 213 221 1092 New Zealand: +64 (0)28 2558 3782

Development is open for future release of v5.8.x series
by Daniel-Constantin Mierla 04 May '23

04 May '23

Hello, the branch 5.7 was created, therefore the master branch is open for adding new features, to be part of future release series v5.8.x (or whatever version is decided for next series). Any bug fix committed to master that applies to 5.7.x or older stable branches should be backported as usual with "git cherry-pick -x ..." to appropriate branches like 5.7 or 5.6. Expect that v5.7.0 will be released in a few weeks from now. Based on the workflow used during the past years, the next future release v5.8.0 should be out after another 8-10 months of development, plus 1-2 months of testing, so sometime during the first part of 2024.

Branch 5.7 has been created
by Daniel-Constantin Mierla 04 May '23

04 May '23

Hello, the branch 5.7 has been created, to be used for releasing v5.7.x series. To check out this branch, the following commands can be used: git clone https://github.com/kamailio/kamailio kamailio-5.7 cd kamailio-5.7 git checkout -b 5.7 origin/5.7 Pushing commits in this branch: git push origin 5.7:5.7 Note that 5.7 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 5.7 branch: git cherry-pick -x COMMITID In few weeks, the first release from branch 5.7 will be out, respectively Kamailio v5.7.0.

send reply from branch route?
by Benoit Panizzon 04 May '23

04 May '23

Hello Is there a possibility to send a reply from within a branch route? Experimental case (yes, I know it's a non working set-up, but I just wonder if that would be possible). Two registrar nodes, location information shared between the two. CPE registers via TLS, therefore the existing connection shall be used towards the CPE and that only exists on one of the registrars. So in the Branch Route I would like to do something like: $var(socket) = $(ulc(aor=>socket)[$T_branch_idx]); if ($var(socket) == 0) { send_reply("503","no local socket"); } This would cause the core routing instance to select the next registrar from the dispatcher list which hopefully holds the active socket. But none of the 'send_reply' variants seem to be allowed within a branch route. Or is there a better solution?

Branching 5.7 on git repo for 5.7.x releases
by Daniel-Constantin Mierla 04 May '23

04 May '23

Hello, I am planning to split 5.7.x series on its own git branch 5.7 on Thursday, May 4, 2023. After that, master branch will be open for new features (to become part of 5.8 or what ever version will be decided to be next). Usually testing should continue for branch 5.7 for another 1-2 weeks, then, if no relevant road blockers pop up, we should release 5.7.0 as first stable version in the 5.7.x series.

uac.reg_add to database
by Jon Bonilla (Manwe) 04 May '23

04 May '23

Hi 5.6.4 I'm trying to add uacreg logic to my setup. When I add a new entry via rpc I see that the reg is stored in mem but not inserted in the database for persistency. My uac params are like this: modparam("uac", "reg_db_url",DBURL) modparam("uac", "reg_timer_interval", 900) modparam("uac", "reg_retry_interval", 10) modparam("uac", "reg_random_delay", 0) modparam("uac", "reg_hash_size", 12) ## 5.6 modparam("uac", "reg_db_table", "kam_uacreg") modparam("uac", "reg_contact_addr", "192.168.255.254:5060") #Won't be used #modparam("uac", "default_socket", "udp:192.168.0.125:5060") #Won't be used modparam("uac", "reg_keep_callid", 1) modparam("uac", "reg_active", 1) modparam("uac", "reg_gc_interval", 30) modparam("uac", "reg_use_domain", 0) I'm used to add via rpc and have db persistency. Like for exmaple using the domain module. Is this a bug in my config or does this module behave different? Should I insert in the db and call to enable via RPC? If so, what would be the best way to enable only the new inserted register instead of reloading all the regs? It's expected to have many changes and do not want to have full reloads all the time. cheers, Jon -- PekePBX, the multitenant PBX solution https://pekepbx.com

Kamailio - asterisk - ACK
by Péter Dr. Barabás 03 May '23

03 May '23

Hi all, we are developing a softphone mobile application which registers to asterisk through kamailio. Kamailo proxies the request to asterisk and replies from asterisk to the clients. Registration works fine with asterisk authentication. The problem appears in the following flow: 1. Mobile client A calls client B. 2. Asterisk gets INVITE through kamailo, sends back 401, and get INVITE with credentials. 3. Asterisk sends invite to client B towards kamailio. 4. Kamailio forwards INVITE if client is registered or sends a push notification to client B. When client B registers, kamailio continue the suspended transaction and forwards INVITE. 5. Client B gets INVITE, sends a SIP OK. 6. Asterisk gets SIP OK through kamailio and sends an ACK to client B, which is OK. 7. Asterisk sends the SIP OK to client A through kamailio. 8. Kamailio forwards SIP OK to client A but the contact address contains the asterisk IP instead kamailio. 9. Clilent A try to send ACK but it does not arrive to asterisk, and the call will be hungup after 30 secs. So the question is what is missing, what is the correct solution? I try to use the provided configuration given in following link: https://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb The difference is that kamailio has no access to asterisk database. Thanks for your help. With kind regards, Peter

RFC: selective backports to latest stable as a dedicated git branch
by Daniel-Constantin Mierla 03 May '23

03 May '23

Hello, during past on-site/online devel meetings as well as on mailing lists or tracker, there were various discussions around the idea or requests to make new features available quicker to stable branches. Of course, one can do local git cherry-picking, but I thought to bring this in discussion and see if makes sense to get something more coordinated between developers and community. Therefore I am cross-posting to sr-dev and sr-users to see if there is interest for it from both communities. Somehow inspired from Debian, my first idea would be to create a "x.y-backports" branch, where "x.y" is the branch for the stable release series. For example, with 5.6 release series built from branch "5.6", there could be "5.6-backports" branch which is kept in sync in "5.6" but also can get "selected" new features from devel (master branch) backported. The "selected" new features should be mostly a matter of the people willing to put effort in backporting, but I would consider a list recommendations not to end up with devel and backports branches being more or less the same. For example, in the "no-backporting" list: - no backporting of completely new modules - no backporting of significant changes to the config file language and native scripting interpreter In the "ok-to-backport": - updates to enable use with newer versions of external libraries - changes to make some functions/modules to cope better with the core infrastructure or end points Commits to the backports branch can be proposed via pull requests. The backports branch should be done only for latest stable version, picking from the development version. Right now it would be 5.6, but we can wait till 5.7 is released and then have it for it. No packaging and no official releases should be made from backports branch, only a git branch to be maintained as a community effort. Of course, if someone wants to put more resources into it, we can discuss about. Anyhow, the first questions would be if such branch sounds good to have and if there are people that think they can also contribute to maintain it.

Clarification of 'return false' behaviour
by Patrick Wakano 03 May '23

03 May '23

Hi list, Hope you are all well! I'm using Kamailio version 5.6.4 (installed from the repo rpm.kamailio.org/centos/7) and noticed that every route that uses "return false" is exiting the script, instead of returning.... This was not the case on version 5.4.6 as the same script is running fine..... From this page https://www.kamailio.org/wikidocs/tutorials/faq/main/#how-is-the-function-r…, I would think that when a route returns false, it would return -1 and not stop execution, since negative is equal to false, but it is actually stopping (same as return 0)... So, as an example, this test code doesn't work as expected. In case the source is a public IP, the script doesn't print the "SRC public" it just exits and then of course every other logic meant to be done is not executed.... route[is_src_private] { if (is_ip_rfc1918("$si")) { return true; } return false; #return is_ip_rfc1918("$si"); *# this doesn't work too in case the $si is a public IP* } request_route { ... if (route(is_src_private)) { xlog("L_NOTICE", "SRC private\n"); } else { xlog("L_NOTICE", "SRC public\n"); } ... } If is_src_private is changed to return -1 instead of false, then it all works fine. Also, I noticed that the following code will print "TEST: 0" in case the $si is public and then stop execution. So looks like false is really being converted to 0, but I guess that's unexpected... anyway apologies if I'm missing something obvious.... route[is_src_private] { $var(t) = false; if (is_ip_rfc1918("$si")) { $var(t) = true; } xlog("L_ERR", "TEST: $var(t)\n"); return $var(t); } I could not find a recent ticket or email related to this situation and I've already spent hours trying to understand what is the logic/problem here, so would anyone have been across a similar case that could provide some insight and clarify what is the expected behaviour of the *false* usage (and boolean in general if possible)? Thank you, Kind regards, Patrick Wakano

rtpengine module: sdp offer in message reply, ip protocol version not passed to rtpengine?
by Benoit Panizzon 02 May '23

02 May '23

Hi Team I think, I might have found something that was overseen in the rtpengine module. A (ipv6) <=> rtpengine <=> B (ipv4) Invite+SDP from B to A It looks like this works as expected. A SDP c= line is created containing an ipv6 address. Invite, no SDP from A to B Reply with SDP offer from B to A The information about A being reachable via ipv6 and therefore an ipv6 c= line being required, could be taken from the via header of the reply. But am I right to fear, that the rtpengine module does not do this at the moment?
