tm stats on prometheus
by Alexis Fidalgo 25 Feb '25

25 Feb '25

Hello all, i found that tm stats (kamcmd tm.stats) are not present in the response of xhttp_prom (prometheus), so in new configurations that we applied, we have no information/stats on reply codes. Is there a way to add this information to the xhttp_prom response? thanks in advance. regards

Kamailio uses an ephemeral IP port instead of the port defined in $fs
by Leonid Fainshtein 24 Feb '25

24 Feb '25

Hi, I am using Kamailio v.5.8.4 on Ubuntu 24.04, kernel 6.8.0-51-generic In the configuration script I explicitly set $fs="udp:adrr:port". In normal situations, it works properly and I see that the UDP SIP requests are sent from the requested IP and port. Due to some reasons, free space on the server root filesystem was exhausted. I cleaned up the file system and everything looked good except the fact that Kamailio started to send messages from ephemeral IP ports instead of the port defined in $fs. Restart of Kamailio didn't solve the problem. But the server reboot fixed the issue. I don't understand how the lack of free disk space can cause such a problem and I'm afraid that there is another reason that I am missing. Has anybody seen such a problem? Best regards, Leonid

Outdated location information on deleted registrations
by Mathias Schneuwly 19 Feb '25

19 Feb '25

Hi I'm using Kamailio 5.8.4 and the python KEMI module. When I move the registration from one device to another, I can see for a while two entries with 'kamctl ul show' where the Expires parameter of the "old" registration is set to "deleted" and the "new" registration shows the seconds until the registration expires. "Address": "sips:200101@10.0.1.130:42323 ;transport=tls", "Expires": "deleted", -- "Address": "sips:200101@10.0.1.129:56374 ;transport=tls", "Expires": 3600, So far so good. When I try to fetch the actual registration address using "registrar.reg_fetch_contacts" or "registrar.lookup_xavp", I'm always getting the "old" deleted registration address instead of the new address as long as the deleted record is not removed. Feb 18 10:05:51 ttel /usr/sbin/kamailio[2356327]: WARNING: {1 511 INVITE 952600514-5060-52(a)BA.A.C.BCI} <core> [core/kemi.c:157]: sr_kemi_core_log(): reg_fetch_contacts: sips:200101@10.0.1.130:42323;transport=tls Feb 18 10:05:51 ttel /usr/sbin/kamailio[2356327]: WARNING: {1 511 INVITE 952600514-5060-52(a)BA.A.C.BCI} <core> [core/kemi.c:157]: sr_kemi_core_log(): lookup_xavp: aor=200101, uri=sips:200101@10.0.1.130:42323;transport=tls, socket=tls:10.0.1.1:5061, dsturi=None I also see that the database is only updated after the deleted entry is removed. Until then, the database still contains the old address. Btw, I'm using "modparam("usrloc", "db_mode", 2)", which would explain the delayed persisting into the database. 62|uloc-67b44aae-23f48e-2|200101||sips:200101@10.0.1.130:42323 ;transport=tls|||2460724.91858218|-1.0|482845299-5060-1(a)BA.A.B.BDA|2002|2460724.87691551|0|0|Grandstream GXV3350 1.0.3.52|tls:10.0.1.1:5061 |7135|<urn:uuid:00000000-0000-1000-8000-C074AD188038>|1|0|52|0|16 I'm asking myself whether the behavior is correct that "registrar.reg_fetch_contacts" and "registrar.lookup_xavp" are returning the deleted information instead of the "new" registration information? If yes, is there another way how I could get the "new" registration information? I'm not really interested in the old outdated information... Best regards Mathias

Info: maintenance work for kamailio.org server on Tuesday, Feb 18, 2025
by Daniel-Constantin Mierla 18 Feb '25

18 Feb '25

Hello, there is a planned mainenance work on the infrastructure for the server hosting kamailio.org services (among them: the main website, wiki, mailing lists) on next week, Tuesday, February 18, 2025, to start about 10:00am Berlin time (CET). Expect some intervals of unavailability, we hope they will be short and most of them not noticeable for the majority accessing these services during the day. Once the work is finished, an announcement will be sent out. The apt repository, github project and the matrix chat channels should not be affected, they can be accessed as usual and can be used a backup communication channels if anyone observes something that has to be addressed.

Asterisk ConfBridge behind Kamailio+Rtpengine
by Rahul mm 18 Feb '25

18 Feb '25

Dear all, Thanks for the amazing product ! I’m trying my hands on a scenario involving Asterisk for video_sfu and a bunch of webrtc and sip clients. The condition is that every call must essentially be a conference call for the participants to add more dynamically. I front ended asterisk with Kamailio and RTPEngine for ssl offloading, load balancing, and registrations. So when one user is present in the conference (his invite SDP containing one audio and one video line) i get local video and MoH back, but when another user joins in and a re-invite is send from asterisk containing two video lines - one for the sendrecv and other for send only, rtpengine doesn’t process the sendonly video line - keeps it as is RTP/AVP instead of making it *UDP/TLS/RTP/SAVPF.* *Is there a way to achieve that? or I’m on the wrong path ?* BR, RM

Kamailio - asterisk registration issue & transparent proxy
by Enzo Damato 17 Feb '25

17 Feb '25

Hi. I'm working on setting up kamailio as a load balancer for some asterisk instances. I've build a configuration that is working for the most part, but I am encountering issues with calls from the asterisk instances to users who's registrations were processed through the kamailio instance. When these users register, asterisk saves thier AOR as the address of the kamailio instance, and then subsequently tires to send invites to kamailio, instead of to the UAC. Since kamailio just proxied the registration, without actually registering the user, it doesn't know what to do with the invite, and the call fails. I would like to configure kamailio to rewrite the sip requests so that all traffic appears to be coming from the end user, rather than from the kamailio instance, essentially making the proxy transparent. Is this possible? Thank you, Enzo Damato

Prioritize specific codecs
by Temilolu Fayomi 17 Feb '25

17 Feb '25

Hello, I am working with inbound calls on kamailio (specifically fax), and was wondering if there was a way to re-prioritize the codecs found in the sdp of an invite. I've looked at using the sdpops module, but haven't been able to re-arrange the priority of the codecs listed. I've tried removing codecs to help incoming faxes switch over to t38 per my upstream providers instructions (calls will do a t38 re-invite if the g729a is the highest priority). I am just looking for which direction to go from here or if I misunderstand the nature of faxing and kamailio. Thank you in advance, Temilolu Fayomi

Constant crashes across versions
by Jon Bonilla (Manwe) 17 Feb '25

17 Feb '25

Hi all I have a setup of several proxies behind a load balancer and all of them have several coredumps every day. I've tried versions 5.3, 5.5 and 5.8 and all of them crash I didn't have dbgsym packages installed but now I've built a 5.8.4 version in one of them and can gdb the coredumps. Can't see anything particular and I'm wondering if I'm doing anything wrong. I'm descompressing the coredump with lz4cat. Sometimes I see that the system generates 3 coredumps at the same time. I've tried running gdb in one of them and exec "bt full" I usually see "can't access memory" in some of them but inb others I don't see anything relevant. I'm attaching one coredump. I don't even know if I'm doing it properly. Could you please guide me to how to debug what's going on? thanks

DNS Unlinked Warnings
by John Larsen 10 Feb '25

10 Feb '25

Hi Everyone, We recently attempted an upgrade from kamailio 5.5.7 to 5.7.6. We immediately started to receive a log of warning logs similar to `dns_hash_put_shm_unsafe(): unlinked item 0x7f08799dcd90` The code shows that this warning log was added to the DNS cache in september 2023 - but its unclear what it means to have an unlinked item exactly? Is anyone able to shed any light on how DNS entries might become unlinked, and what the implications of it are? thanks John Larsen John Larsen Tech Lead EJohn.Larsen(a)symbio.global W symbio.global This communication is intended only for the person to whom it is addressed and may contain confidential material.

switch between "sips:" and "sip:" schema
by James Lipski 10 Feb '25

10 Feb '25

Hello, I have a kamailio installation where it's basically doing transport protocol translation. To go into more detail, I have a UA communicating over TLS towards kamailio/ and kamailio forwards the request to a freeswitch installation via UDP, so call-flow is as follows: UA <-- (TLS) --> Kamailio <-- (UDP) --> Freeswitch For the most part, this does work/ it's only when I use a UA that uses "sips:" as the schema instead of "sip:" where issues occur -- in my current topology, freeswitch has some weird behavior where it doesn't disconnect the call properly. At least based on my testing, I believe the issue is relating to the schema -- as the UA in question does have the ability to switch between schemas/ when using "sip:" instead of "sips:" over TLS, no issues with the same call-flow. In the event that I do come across a UA that doesn't have that ability, I was wondering if kamailio has the ability to switch schemas when it sends traffic over the UDP connection. I'm able to replace most aspects of the packet with "sip:" however the only header which contains the "sips:" schema is the contact header. With this alone, it propagates to the B-leg side (UDP side) of the call; and will cause freeswitch to not disconnect calls properly. I'm using the topos module to obfuscate my topology, not sure if that matters. -------- For example, on the A-leg side of the call, kamailio receives this: INVITE sips:12125551000@dev-sip.server.com:5061 SIP/2.0 Via: SIP/2.0/TLS 172.16.1.194:5061;branch=z9hG4bK236557042;rport;alias From: <sips:100000000@dev-sip.server.com>;tag=444048970 To: <sips:12125551000@dev-sip.server.com> Call-ID: 1326419916-5061-4(a)BHC.BG.B.BJE CSeq: 21 INVITE Contact: <sips:100000000@172.16.1.194:5061;transport=tls> Proxy-Authorization: Digest username="100000000", realm="dev-sip.server.com", nonce="Z6Ig0WeiH6Vdxtvej0I3XGCTUAEfh+0/", [uri="sips:12125551000@dev-sip.server.com](mailto:uri=)", response="43c1487d077db36a70fffdd1e25b3b52", algorithm=MD5 Max-Forwards: 70 User-Agent: Grandstream HT812 1.0.57.1 Supported: replaces, path, timer, eventlist Allow: INVITE, ACK, OPTIONS, CANCEL, BYE, SUBSCRIBE, NOTIFY, INFO, REFER, UPDATE Content-Type: application/sdp Accept: application/sdp, application/dtmf-relay Content-Length: 1034 v=0 o=100000000 8000 8000 IN IP4 172.16.1.194 s=SIP Call c=IN IP4 172.16.1.194 t=0 0 m=audio 5004 RTP/SAVP 0 101 a=sendrecv a=rtpmap:0 PCMU/8000 a=ptime:20 a=rtpmap:101 telephone-event/8000 a=crypto:1 AEAD_AES_256_GCM inline:UlX3PAjNBP/aQwtwyf5ymsfJciB+VdFxMElO5zLVooUqmcEzZ8YyQQk9stI=|2^32 ------------------------------------------------------ On the B-leg side of the call, kamailio forwards the following to freeswitch: INVITE sip:12125551000@fs.server.com SIP/2.0 Via: SIP/2.0/UDP 10.64.52.113:5080;branch=z9hG4bK1552.89ec9666294034a5611f908f2a6a427e.0;i=f From: "Test" <sip:16461234567@dev-sip.server.com>;tag=444048970 To: <sip:12125551000@fs.server.com> Call-ID: 1326419916-5061-4(a)BHC.BG.B.BJE CSeq: 21 INVITE Max-Forwards: 15 Supported: replaces, path, timer, eventlist Allow: INVITE, ACK, OPTIONS, CANCEL, BYE, SUBSCRIBE, NOTIFY, INFO, REFER, UPDATE Content-Type: application/sdp Accept: application/sdp, application/dtmf-relay Content-Length: 316 Contact: <sips:btpsh-67a21ca2-2dbe86-1@10.64.52.113:5080> v=0 o=100000000 8000 8000 IN IP4 10.64.52.113 s=SIP Call c=IN IP4 10.64.52.113 t=0 0 m=audio 13060 RTP/AVP 0 101 a=rtpmap:0 PCMU/8000 a=rtpmap:101 telephone-event/8000 a=sendrecv a=ptime:20 -------------------------------------------------- As with the above, I was wondering if there is a way within kamailio to switch schemas on the b-leg side of this call example; specifically is there a way to update the contact header so it doesn't use the "sips:" schema when it traverses the UDP connection.

Strange memory stats

RTPengine module - pause/resume recording
by Who AmI 28 Jan '25

28 Jan '25

Hi list, I have been looking at the recording daemon in RTPengine with Kamailio controlling this via rtpengine_manage() flags: "record-call=on" in the initial Invite, or 200OK based on direction. I tested and this works brilliantly for the full calls, but when looking at pause/resume the module documentation is bare and I am a bit confused. It looks like the ngcp docs and Opensips module docs (for RTPengine) describe the pause/resume as just another start/stop flag. Use case is simple, all calls are recorded, but we want the option to pause, then resume once any private or personal information exchange has completed. My question is also simple - Is this the recommended way to pause and then resume recordings or have I missed something? The Kamailio documentation doesn't explicitly say this ( https://www.kamailio.org/docs/modules/stable/modules/rtpengine.html#rtpengi…) so just looking for advice if this is the best route to go. Thanks, John.

We the old-Makefiles kept, it is doable, the wiki pages needs to be created for this release series, which I can do tomorrow, as I waited to see if how it should be the recommended method for compilation/installation. If the feeling is that we should wait, then probably the target date has to be shifted somewhere in the week starting on February 10, 2025, because Fosdem follows this weekend and then some countries have a week holiday break. If no other opinions and change of decision, the release will be done on Wednesday, with content using the old-Makefiles (to reuse existing tutorials) and reference to cmake variant when it is the case.

Hello, just wondering if there is any way to define 2 constants as : # sets quarantine period the URL is set, in secs, after number of HTTP_RETRIES retries #!define SOME_VAR_1 60 # sets the configuration values for HTable module parameter #!define SOME_VAR_2 "some_configration_value" + SOME_VAR_1 I couldn't find anything in docs, and made several different ways without success. Any suggestions? Atenciosamente / Kind Regards / Cordialement / Un saludo, *Sérgio Charrua*

UDP worker lock investigation
by Володимир Іванець 26 Jan '25

26 Jan '25

Hello everyone! I was wondering if it is possible to get information about a packet that is being possessed by the worker without increasing log level? I have an installation with Kamailio that is configured with two interfaces. Once in a while Kamailio stops accepting requests on one of the interfaces. It works fine for requests from other one. I think that worker processes might be locked while processing some requests. Enabling debug log is not an option because the traffic is quite high and the log file will not just be enormous, some lines will be missing. It looks like syslog will skip some of the log entries. So is it possible to check what packet worker process is currently processing? Or do I need to add some log entries with lower log level to trace requests manually? Thank you!

How to access registration contact user agent string in branch route after location lookup?
by Benoit Panizzon 24 Jan '25

Hi List I have some CPE which require special handling like removing 100rel and update from the supported methods because they misbehave. Previously, I was using reg_fetch_contacts and then appending the branches manually and stacking the UA in an AVP. With the branch index this allowed me to get the AVP containing the UA to which the call was branched in the branch route and perform filtering of methods based on UA, but it was complicated. Now I use the intended function lookup_to_dset() but now I miss how to access the register contact UA from within a branch route. Is there an intended way to access that information?
