Topos methods_nocontact parameter
by Benoit Panizzon 27 Feb '24

27 Feb '24

Hi I'm having another go at topos trying to solve an issue of sip messages getting to big for certain clients to process. Unfortunately some methods (ACK/PRACK/BYE probably CANCEL) do not contain a contact header, therefore the topology is still revealed (and potentially a lot of via header inserted increasing message size). Is it safe to set methods_nocontact to an empty string to force creation of a Contact header for every SIP method? Is there another way to completely hide topology aka keeping header small?

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.

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

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.

So I am not sure whether this flag was defined during 5.6.5 deb build time or it has been somehow lost? So I need your advice. Regards, Arsen

How to query, if callid is handled by rtpengine module already?
by Benoît Panizzon 20 Feb '24

20 Feb '24

Hi I have come across this challenge: Initial invite (no to_tag) has is authenticated and has credentials. So a lookup for the username is made to determine if the customer needs backhauling, thus rtpengine needs to be engaged. On a subsequent invite (re-invite to change codec or to refresh session timer) there is a to_tag so it is being routed without sending a challenge and has no auth username. I don't use dialog on the registrar. This is another transaction. So I don't know, if I need to engage rtpengine on that DSP or not. What is the best way to find out, if rtpengine is already handling that callid? if(rtpengine_query_v("j", "$var(dummy)")) { rtpengine_manage(); } basically works, but generates a couple of ugly error messages in the log as rtpengine_query_v does not find the call. Is there a nicer way? -- 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 ______________________________________________________

TCP timeout occurs when the uac_req_send sets $ouri = Received (sip:10.11.40.XX:57646;transport=tls) but The Received connection normal
by riffs＠sina.cn 20 Feb '24

20 Feb '24

The connection registered by the client is normal, and the client can send messages and renew the registration normally, but the push message to the client using uac_req_send() from kamailio fails. Location information after the client is registered: ]#kamcmd ul.lookup location test01 Received: sip:10.11.40.XX:57646;transport=tls ]#netstat -anp | grep 57646 "tcp 0 0 10.11.55.xx:5061 10.11.40.XX:57646 ESTABLISHED 3467/kamailio" kamailio.lua KSR.pv.sets("$uac_req(ouri)", rows.received) In this way, most users can receive messages normally, but occasionally some users cannot receive messages but can renew their registration and send messages normally. Once this is the case for this user, the use of uac_req_send() will continue to fail until the client establishes a new connection. If a problem occurs, the following logs are displayed on the server: 2024-02-20T10:01:25.329595+08:00 10.11.55.XX (72819) ERROR: <core> [core/tcp_main.c:4692]: tcpconn_main_timeout(): connect 10.11.40.XX:57646 failed (timeout) The connection already exists and should be normal, why does "tcpconn_main_timeout(): connect 10.11.40.XX:57646 failed (timeout)" occur.

Dispatcher ping: "binding to source address X.X.X.X:XXXX failed: Address already in use" for TCP and TLS destinations
by Jardar Leira 17 Feb '24

17 Feb '24

We have recently upgraded from 5.6.4 to 5.7.4. No change in the KAMAILIO configuration. On all upgraded servers we are now getting this message in the logs for every destination when the dispatcher sends out OPTIONS to destinations listed in the dispatcher list: WARNING: <core> [core/tcp_main.c:1301]: find_listening_sock_info(): binding to source address X.X.X.X:YYYY failed: Address already in use [98] The X.X.X.X being the servers IP address and YYYY being the servers listening port for tcp and/or tls. It's not consistent. For some servers it's every time OPTIONS is sent. For others it's just now and then. udp destinations have no issues. There are no other processes occupying these ports. Changing the listening port on the KAMAILIO also results in the new port reported as in use. Dispatcher OPTIONS still seems to work for both tcp and tls. Unsurprisingly using a dynamic, unprivileged port > 1023 and not the server port as the source port, as it shouldn't. The packages are sendt and a reply is registered. Inbound OPTIONS are processed as expected by KAMAILIO on the listening port. Have I missed something transitioning from 5.6 -> 5.7, or is this a bug? Relevant config: modparam("dispatcher", "ds_ping_method", "OPTIONS") modparam("dispatcher", "ds_probing_mode", 1) modparam("dispatcher", "ds_probing_threshold", 2) modparam("dispatcher", "ds_ping_interval", 120) modparam("dispatcher", "ds_ping_from", "sip:ping@xxxxxx.xxx") modparam("dispatcher", "ds_ping_latency_stats", 1) OS: Debian Bullseye Kamailio installed from https://deb.kamailio.org/kamailio57 bullseye Best regards, Jardar Leira

Forward subscriber username via dispatcher
by s.czech＠nowatel.com 16 Feb '24

16 Feb '24

Hi, I'm trying to forward the original username of the peer via Kamailio dispatcher to the Asterisk and I can't get it working. The scenario looks like this: Client Phone (username 1) -> Asterisk Client ---trunk(test-trunk)--> Kamailio Dispatcher/RTPEngine --trunk--> Asterisk Final Client is dialing via Asterisk Client with a simple extension: exten => _X.,1,Set(CALLERID(all)= 587555611 <587555611>) exten => _X.,n,Dial(SIP/${EXTEN}@test-trunk) Asterisk Client is registering to the Kamailio with its own credentials and Kamailio is registering in the Asterisk Final The problem is that I can't find a way to extract the original trunk username (like test-trunk) in the outgoing connection to the Asterisk Final (via Kamailio): Since i'm using the CALLERID on the Asterisk Client all I can see on the Asterisk Final is: INVITE sip:587322591@192.168.20.74 SIP/2.0 Record-Route: <sip:587322591@192.168.20.74;lr;ftag=as52b874a1;nat=yes> Via: SIP/2.0/UDP 192.168.20.74;branch=z9hG4bKc6e3.a77db1f002191ae3ee1a414b63d34a72.0 Via: SIP/2.0/UDP 192.168.21.228:5060;received=192.168.21.228;branch=z9hG4bK705ec94a;rport=5060 Max-Forwards: 69 From: "587555611" <sip:587555611@192.168.21.228>;tag=as52b874a1 To: <sip:587322591@192.168.20.74> Contact: <sip:587555611@192.168.21.228:5060;alias=192.168.21.228~5060~1> Call-ID: 433f9ff84cdb437f0d383797003c232f@192.168.21.228:5060 CSeq: 102 INVITE User-Agent: Asterisk PBX 16.29.0 Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY, INFO, PUBLISH, MESSAGE Supported: replaces, timer P-Asserted-Identity: "587555611" <sip:587555611@192.168.21.228> Content-Type: application/sdp Content-Length: 268 There is no way I can forward the 'test-trunk' in the SIP header. I tried to add append_hf to ROUTE[relay] like append_hf("X-Trunk $au r\n"); but if the trunk is already registered then $au is null or the CALLERID value. How to extract the original username (test-trunk) on the Asterisk Final? Do you have any ideas? Thank you in advance ;)

Latest point releases seem to break early dialog UPDATEs from B-side when using topos (again)
by George Diamantopoulos 16 Feb '24

16 Feb '24

Hello all, I've noticed that there seems to be a regression with the topos module, more specifically the redis flavour, but I'm assuming the storage backend shouldn't make a difference. I have confirmed this affects both 5.6.5 and 5.7-nightly, so I'm assuming some backported commit is to blame. Kamailio 5.6.4 used previously, to the best of my memory, was not affected. Early dialog UPDATEs sent from the callee seem to be somehow malformed, since the 200 OK the UAS produces goes directly to the UAC despite having executed record_route() for the original INVITE. I can't imagine how this is possible, I thought responses always honour the Via header and record route shouldn't play a role in this case, right? Simply turning topos off restores the intended behaviour, however, so I can't help but think this is somehow related. Here's two call flows demonstrating the behaviour: * Topos on, 200 OK to UPDATE missing: https://pastebin.com/raw/J0zQeM5g * Topos off, 200 OK to UPDATE routed correctly: https://pastebin.com/raw/49yErezb I was wondering if anyone is aware of any commits that might be responsible for this. Additionally, is there an archive of debian packages with previous point releases so that I can confirm this regression with the latest versions? Thank you! Best regards, George

uacreg - memory vs database
by Aymeric Moizard 15 Feb '24

15 Feb '24

Hi! I would like to add/remove/update entries in uacreg database. The easiest way I found is to add data using mysql and then call kamcmd uac.reg_reload. I end up reloading too often: uac_reg_ht_shift(): shifting in-memory table is not possible in less than 150 secs I would like to optimize it and I tried to use sudo kamcmd uac.reg_add Unfortunately, the data is not persistent and seems to be only in memory. Does it means my only choice is to follow this procedure: Add a user: 1/ sudo kamcmd uac.reg_add 2/ add the equivalent mysql entry Remove a user 1/ sudo kamcmd uac.reg_remove 2/ remove the equivalent mysql entry Let me know if an alternative exists!

Kamailio as a Presence server only
by djcsalvador＠gmail.com 15 Feb '24

15 Feb '24

I all, I'm looking into Kamailio as a solution to replace our current Presence Server in our IMS Network, but feeling a bit overwhelmed by the feature size and complexity of Kamailio. I have a few questions (some might be dumb), if you guys could help me I would appreciate. 1. As I only need Kamailio as a Presence Server (with XCAP and SIP Interface), is there a way to install only the necessary components and/or modules? Our security team would probably raise some questions if we need to install unused code on the network. For what I could investigate, the modules i would need are: * Presence * Presence_XML * Xcap_server * xhttp * RLS * Pua * database * sl * tm Am I missing something? 2- As refered on point 1, our server will need a xcap and sip interface. Some presence updates will come through XCAP, others from SIP Publish. My question is, whenever a presence update is made through XCAP interface, will the kamailio server trigger the necessary SIP Notify to notify all Subscribed users ? I ask this because this was a problem with our current supplier. 3 - our client is a bit "peeky" with performance. I found here (https://www.kamailio.org/wikidocs/kemi/performance-tests/5.2.x/#results) some performance tests, but for what i can see the test primary goal was to test the response time. Is there any resource on "requests per second"? Thanks in advance for all the help David Salvador

There is a quote that raises a question: “Things, you shouldn’t expect (at least initially): ● Seamless handover between LTE and Wifi, as this requires some integration with the PGW of the LTE” My question is: Has the VoLTE <-> VoWiFi Handover been implemented in the meantime?

Trying to better understand pre-made IMS configs
by Enzo Damato 10 Feb '24

10 Feb '24

Hello. I am a new Kamailio user, and I have been following the instructions for setting up a new IMS system. So far, I have a system that is working with the default example configs, but I am am trying to figure out the best way to expand on these default configurations. Currently, from my reading, the pcscf and icscf have minimal configuration/customization beyond the basic setting required to get them working, and most of the configuration related to routing, features, and other typical telecom customization should be done in the scscf. Is this mostly correct? Additionally, is there a guide to the features that are required in order to get the IMS systems working above and beyond the minimal config to get Kamailio itself working, so that I know what it's safe to modify and what should be left alone? Thank you, Enzo Damato

High CPU with DMQ on ARM64 (graviton) - Tuning values for DMQ worker_usleep
by Ben Kaufman 09 Feb '24

09 Feb '24

I encountered a behavior with DMQ using excessive CPU when running kamailio 5.8 on AWS Graviton processors (running in Docker on Amazon Linux 2023), even on an otherwise idle system. Finding the issue below pointed me towards using polling. I set the value for worker_usleep to 1000 as a test, and that seems to have resolved the CPU issue, but I have no idea of what a "good" value is for this setting, and 1000 was simply the example present in the documentation. My specific use case for DMQ is synchronizing USRLOC data for ~7,500 users, registering with expiration times of 60 - 300 seconds with 7 - 9 nodes on the DMQ bus. Any general recommendations on tuning values for this setting? https://github.com/kamailio/kamailio/issues/822 Regards, Kaufman

Also have defined: listen=tls:10.129.1.168:5061 advertise ${PUBLIC_IPV4}:5061 Routing from rtjson is working fine for TCP / UDP connections, however - once I try to forward an INVITE via rtjson using TLS, then the TLS connection is simply closed with Kamailio reporting "tcp_read_data(): EOF on connection". Please see logs and setup below. - tcp_reuse_port = yes, tcp_children = 8, tcp_accept_no_cl= yes & tcp_connection_lifetime=3605 - Also no success with tcp_reuse_port = no - I have HOMER setup and see here that SIP headers from the RTJSON is being used (Outbound SIP Invites is being duplicated to HOMER before connection is released) - I see no drop in traffic from my firewall As you can see from logs below, Kamailio is reusing the socket (0x7fc3ebc65060) from the exsisting connection (not new socket 0x7fc3ef70aab0). I am sending SIP Options toward the external endpoint (which is working fine), and my theory is that Kamailio is reusing the exisitng SIP OPTIONS tcp connection for the SIP INVITE and somehow close the connection when RTJSON is used (since routing without RTJSON is working fine). Any idea how to solve this? Thank you!

Get the amount of open TCP connection from routing logic
by Sebastian Damm 06 Feb '24

06 Feb '24

Hello, My plan is to reject new inbound requests if there is already a certain number of open connections on one Kamailio server. I could answer with a 503 and directly close the connection forcing the client to reconnect and the loadbalancer to send traffic to a different node on the next connect. It's just a last-resort measure to prevent Kamailio from running into the configured TCP connection limit (workarounding a poorly-implemented external load balancer). Since I didn't find anything in the docs: Is there a pseudovariable containing the current number of open tcp/tls connections on this Kamailio? I can (and already do) query them via kamcmd or rpc, but can I access the variable from inside the routing script as well? Regards, Sebastian

Development for v5.8.x is frozen
by Daniel-Constantin Mierla 02 Feb '24

02 Feb '24

Hello, the formal notification that the development for the next major version 5.8.0 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 5.8 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 5.8. 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 5.8. Once the branch 5.8 is created, new features can be pushed again to master branch as usual. From that moment, the v5.8.0 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 5.8 is going to be built at: * https://www.kamailio.org/wikidocs/features/new-in-5.8.x/ Upgrade guidelines will be collected at: * https://www.kamailio.org/wikidocs/install/upgrade/5.7.x-to-5.8.0/ 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 v5.7.x to 5.8.x.

MS Teams Kamailio SBC tcp timeouts
by maps＠ua.pt 01 Feb '24

01 Feb '24

Hello everyone. I have setup Kamailio as an SBC for Microsoft Teams following the link provided in the documentation https://skalatan.de/en/blog/kamailio-sbc-teams and everything was working perfectly until recently. The problem I am having is that starting a few weeks back, Kamailio starting showing the errors below. These errors appear without the need to do anything, meaning without making any sort of call, even with Kamailio sitting idle. Since the problem started I looked around and found out that the issue seems to come from the fact that sometimes the SIP Options request being sent to microsoft is not being answered. I have configured everything following the guide and I did not make any changes to Kamailio since then that might have caused this issue. I am using kamailio with docker, version 5.7.2-bullseye. Thank you very much. 31(37) ERROR: <core> [core/tcp_main.c:4675]: tcpconn_main_timeout(): connect 52.114.76.76:5061 failed (timeout) 9(15) ERROR: <core> [core/tcp_main.c:1321]: tcp_do_connect(): connect 52.114.76.76:5061 failed Cannot assign requested address 9(15) ERROR: <core> [core/tcp_main.c:1324]: tcp_do_connect(): connect 52.114.76.76:5061: (99) Cannot assign requested address 9(15) ERROR: <core> [core/tcp_main.c:1456]: tcpconn_finish_connect(): 52.114.76.76:5061: tcp_do_connect for 0x7f623d0e91a8 failed 9(15) ERROR: <core> [core/tcp_main.c:2112]: tcp_send(): 52.114.76.76:5061: tcpconn_finish_connect(0x7f623d0e91a8) failed 9(15) ERROR: tm [../../core/forward.h:292]: msg_send_buffer(): tcp_send failed 9(15) ERROR: tm [uac.c:688]: send_prepared_request_impl(): Attempt to send to precreated request failed

Freezing development for 5.8.x series
by Daniel-Constantin Mierla 01 Feb '24

01 Feb '24

Hello, I propose to aim freezing the development for 5.8.x series at the end of the 1st of February 2024 (Thursday). 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 5.8.0. Unfreezing will happen earlier, after the first weeks of testing when the 5.8 branch will be created.

print_dset(): no r-uri or branches
by Ali Taher 01 Feb '24

01 Feb '24

Hello all, I'm using Kamailio as SIP redirect where I'm appending the contact header then send reply back using sl_send_reply("300","Multiple Choices"). But I'm getting "print_dset(): no r-uri or branches" as warning in the log and no packet is sent back from Kamailio to the original sender. I'm using same Kamailio configuration in another setup and it's working correctly without facing this error. I'm not able to detect the issue. Can you please assist? Regards,

What happens when using exit or return in branch route in parallel branching?
by Benoit Panizzon 31 Jan '24

31 Jan '24

Hi I was wondering what exactly happens with parallel branching in this situation: branch_route[BR_T] { if (condition) { # Stuff below not required exit or return } do other stuff before relaying } Will this break, stop the processing of all branches with higher index as the one being processed? From what I observe, I fear this is the case. Could I safely use return(1) (vs return which probably is return(0) thus eq exit)? Or would the only safe option be to wrap the 'other stuff' in an else statement?

install location when compiling
by David Villasmil 30 Jan '24

30 Jan '24

Hello guys, i compiled kamailio and i want it installed on debian's deb location, i.e.: /etc/kamailio /usr/lib/x86_64-linux-gnu/kamailio/modules etc.. I know if i do make prefix=/ all make prefix=/ install the config will end up on /etc/kamailio, but then the modules will be on /lib64... i don't see a way of doing this, is there? Thanks!

Same number of max concurrent requests on backends
by Unai Rodriguez 30 Jan '24

30 Jan '24

Dear List, We're load balancing MRCP requests using Kamailio dispatcher module's call load distribution algorithm. We want to achieve the same maximum number of concurrent sessions on each MRCP backend but because the duration of each request varies, we’re unable to achieve this (at the moment we send the same number of requests to each backend but they all have different maximum concurrent requests). Is there a way/module that will send requests to the backend with the least number of ongoing sessions? My guess is, this module needs to connect to the backends to know their status. Any pointers appreciated. Thank you With best wishes, Unai Rodriguez

Kamailio 5.6 (and 5.7) core dumping.
by Mattis Lind 29 Jan '24

29 Jan '24

Hello Kamailio list! We have a scenario that makes use of the UAC-module to send SIP MESSAGE and then in some cases the Kamailio process core dumps after some time after processing messages. I have been able to gather a core dump which shows this backtrace appended below. We are using Kamailio 5.6 retrieved from the kamailio repository: http://deb.kamailio.org/kamailio56. We are running Kamailio in a Docker container which runs on "5.10.0-25-cloud-amd64 #1 SMP Debian 5.10.191-1 (2023-08-16) x86_64 GNU/Linux" We have previously tried to use Kamailio 5.7 but it gave the same type of crashes. We have been using the uac module a lot but it is just in this scenario we get a core dump. We have some kind of relation to a specific scenario but it can take from several seconds from the last SIP message of this scenario up to 50 minutes until the crash occurs. To me this sounds like some kind of cleanup that is not handled properly. The back trace indicates that free of shared memory could be the issue, but I don't know the code unfortunately. The last things we see in the log file is: 2024-01-23T13:18:08.828+01:00 Jan 23 12:18:08 /usr/sbin/kamailio[4789]: INFO: <script>: Incoming SIP TCP request conid 21 call-id un0rihsRLJLvP-grn6LO-A 2024-01-23T13:18:08.835+01:00 Jan 23 12:18:08 /usr/sbin/kamailio[4789]: INFO: <script>: Incoming SIP TCP request conid 21 call-id WQjhldpRJbxjZRYe7fWgbw 2024-01-23T13:18:08.860+01:00 Jan 23 12:18:08 /usr/sbin/kamailio[4795]: CRITICAL: <core> [core/pass_fd.c:281]: receive_fd(): EOF on 49 2024-01-23T13:18:09.486+01:00 Jan 23 12:18:09 /usr/sbin/kamailio[4751]: ALERT: <core> [main.c:783]: handle_sigs(): child process 4777 exited by a signal 11 2024-01-23T13:18:09.486+01:00 Jan 23 12:18:09 /usr/sbin/kamailio[4751]: ALERT: <core> [main.c:787]: handle_sigs(): core was generated 2024-01-23T13:18:09.516+01:00 Jan 23 12:18:09 /usr/sbin/kamailio[4751]: INFO: <core> [core/sctp_core.c:53]: sctp_core_destroy(): SCTP API not initialized 2024-01-23T13:18:09.570+01:00 Started /root/sipconfig/startkamailio.sh 2024-01-23T13:18:09.570+01:00 info: :-) Starting Kamailio Just before all the crashes we see the "CRITICAL: <core> [core/pass_fd.c:281]: receive_fd(): EOF on 49" log line.

How to achieve conversion from 180 to 183sdp

When receiving to-tag and returning 180 ring without SDP body, how can it be converted into 183 with SDP and returned to from-tag.

usrloc database duplicate keys issue

This leads to this duplicate key error. Is there a way to tell kamailio to use 'replace into' instread of 'insert into'? Solution for now, is to manually delete expired entries from the database. -- 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 ______________________________________________________

Heads-up: testing needed for major OpenSSL refactoring
by Richard Chan 28 Jan '24

28 Jan '24

Hello Kamailio community, After the January refactoring of OpenSSL integration, configurations that initialise libssl in rank 0 (thread #1) are likely to trigger errors more aggressively. This type of configuration has all along been broken due to OpenSSL use of thread-local variables. The first "victim" is https://github.com/kamailio/kamailio/issues/3727 — the configuration has dispatcher + db_unixodbc (+ some driver) — this configuration initialises libssl in rank 0(thread #1). I have a couple of PRs in the queue for db_unixodbc, db_mysql (PostgreSQL may need similar attention). master and 5.7 branches are affected Regards Richard

LCR logic
by Social Boh 27 Jan '24

27 Jan '24

Hello, LCR module logic is : When the function /load_gws()/ is called, matching gateways (that are not currently designated as defunct) are ordered for forwarding purposes as follows: 1. according to longest Request-URI user part match 2. according to tuple's priority 3. according to tuple's randomized weight or, if priority_ordering parameter is set to value 1, as follows: 1. according to tuple's priority 2. according to tuple's randomized weight and Smaller priority value means higher priority (highest priority value being 0 and lowest being 255). so I have 3 lcr_rule_target use the same lcr_rule entry but 3 different Gateways and priority. So the order of rules would be longest Request-URI (same) and the priority but the result is: added matched_gws[0]=[3, 5, 200, 2193562] added matched_gws[1]=[1, 5, 2, 6888519] added matched_gws[2]=[2, 5, 50, 2159388] same prefix but first rule target with priority 200 and then 2 and then 50. I think the result would be priority 2,50 and 100. ¿Or not? --- I'm SoCIaL, MayBe

DMQ dialog sync question
by Stefan-Cristian Mititelu 26 Jan '24

26 Jan '24

Hi, I'm trying a DMQ dialog sync up setup with 2 x Kamailios. I have this scenario: 1. Kamailio1 receives INVITE and sends KDQM to Kamailio2 to sync up dialog => OK 2. Kamailio2 receives 200OK 3. Kamailio2 does not send anything back to Kamailio1 to update dialog state => not OK, i expected a KDMQ to be send back to Kamailio1 to update dialog state I was wondering if DMQ module supports the above? I am using 5.6 version of kamailio, and I am curios if this might be implemented in later branches? Thank you, Stefan

How to correctly drop a branch?
by Benoît Panizzon 26 Jan '24

26 Jan '24

Hi https://www.kamailio.org/wiki/cookbooks/devel/pseudovariables#branch_name_-… "Assigning $null to uri attribute will drop the branch, for the rest of attributes will just set the value to null." Where do I need to assing $null to the brach URI to get it dropped? And what happens to the index, is there a gap, or do the subsequent branches get re-indexed so they don't match with the ulc indexes anymore? Actual example, I have multiple contacts I would like to add to branches. Two of the contacts are from the location database + an additional contact. # Basic Branch: $ru = $(ulc(aor=>addr)[0]); $du = $(ulc(aor=>received)[0]); $fs = $(ulc(aor=>socket)[0]); # Additional Branch: append_branch($(ulc(aor=>addr)[1])); $(branch(dst_uri)[-1]) = $(ulc(aor=>received)[1]); $(branch(send_socket)[-1]) = $(ulc(aor=>socket)[1]); and so on, actually a loop over all ulc contacts. # Lasst Additional Branch, point to other registrar, not to a usrloc location. append_branch($ru); $(branch(dst_uri)[-1]) = "sip:other-registrar:5060;transport=udp"; $fsn = "LocalUDPv4"; $(branch(send_socket)[-1]) = $fs; t_on_branch("BR_T"); branch_route[BR_T] { $var(socket) = $(ulc(aor=>socket)[$T_branch_idx]); if ($var(socket) == 0) { xlog("L_INFO", "$cfg(route): DROPPING BRANCH: $T_branch_idx No local socket on this registrar\n"); $(branch(uri)[$T_branch_idx]) = $null; } } I don't get this right!

Change in LCR Debug
by Social Boh 26 Jan '24

26 Jan '24

Hello, using DEBUG with LCR module to see how the module apply the rules, I see he use Gateway Index in the list. The Gateway Index could be different to Gateway ID and maybe can confuse the correct interpretation about the use of the rules. Is it possible change the code: matched_gws[gw_index].gw_index = t->gw_index; matched_gws[gw_index].rule_id = rule->rule_id; matched_gws[gw_index].prefix_len = pl->prefix_len; matched_gws[gw_index].priority = t->priority; matched_gws[gw_index].weight = t->weight * (kam_rand() >> 8); matched_gws[gw_index].duplicate = 0; LM_DBG("added matched_gws[%d]=[%u %u, %u, %u, %u]\n", gw_index, t->gw_index, pl->prefix_len, t->priority, matched_gws[gw_index].weight); to use gateway ID and not gateway Index?

Hey everyone, I've set it up so that when the invite comes into Kamailio I suspend the transaction (save the transaction info in sht) and use dispatcher to send a request to our NSS server. On the reply from NSS I throw the identity header into a sht and continue the original transaction. Does that seem like the right way to do it? The next things I need to look at are: * if first NSS server doesn't respond quickly, try the second (change some timeouts and use dispatcher to try the backup) * if both NSS servers aren't working, I still want to resume the original call and let it through. Maybe I can keep track of the failures in a sht and if I have two failures, resume the original invite without the identity header. Sound like an ok plan? -- Anthony Wittig Mango Voice Developer > > ---------- Forwarded message ---------- > From: Anthony Wittig <awittig(a)mangovoice.com> > To: sr-users(a)lists.kamailio.org, david.villasmil.work(a)gmail.com > Cc: > Bcc: > Date: Tue, 23 Jan 2024 20:39:09 -0700 > Subject: [SR-Users] STIR/SHAKEN > Thanks! > > This is what I've got so far: > > 1.

Thanks! This is what I've got so far: 1. Kamailio invite -> NSS 2. NSS 302 -> Kamailio 3. Kamailio ack -> NSS I can see the identity header on the 302 response in my onreply_route. How can I replay the same invite from step #1 with the identity header I get back in step #2? Should I be doing something with a transaction on step #1, maybe start a branch that goes out to NSS and when it comes back resume the transaction (these are all words I've heard smart people say, but I don't fully understand them...).

Hello, We're attempting to add identities to our invites. I believe we want to send our invites to the NSS, and it'll reply with a 302'd invite with an identity header. We currently use FreeSWITCH for dialplans and media and Kamailio as our SBC. Should we be trying for something like: FreeSWITCH -> Kamailio -> NSS (302) -> Kamailio -> PSTN or would it make more sense to do: FreeSWITCH -> NSS (302) -> FreeSWITCH -> Kamailio -> PSTN Assuming we wanted Kamailio -> NSS, is using dispatcher the right approach? We currently use it for our two Kamailios and our FreeSWITCHs. We're going to have two NSS servers, one for failover. Any thoughts would be greatly appreciated, thanks! -- Anthony Wittig Mango Voice Developer

How to check for branches with a pending reply in MANAGE_REPLY to correctly handle rtpengine?
by Benoit Panizzon 23 Jan '24

23 Jan '24

Hi gang location database contains multiple contacts for an AOR The invite therefore is parallel branched to those multiple contacts. Each reply from each branch is handled by MANAGE_REPLY. rtpengine_manage() is called in MANAGE_REPLY to stop rtpengine processing a failed call. Unfortunately, if any of the contacts replies with an error rtpengine_manage() will stop RTP processing. Is there a way I could check if there are branches with a pending reply from within MANAGE_REPLY so I could call rtpengine_manage() only when the last reply (no pending replies) are present? Hmm, realizing, if I process the last pending error reply and a prior one got a positive reply, this would still kill media. => How do I solve this?

rr, loose_route and corex alias_subdomains
by Jon Bonilla (Manwe) 19 Jan '24

19 Jan '24

Hi I'm having an issue with the double rr for mst direct routing. I'm using subdomains like 23234.mydomain.com with a wildcard certificate and I set corex modparam alias_subdomains to mydomain.com But loose_route doesn't seem to detect the rr as myself I get the message: rr [loose.c:804]: rr_do_force_send_socket(): no socket found to match second RR (sip:20141.mydomain.com:5063;transport=tls;ftag=as7107d0fe;lr;r2=on;vsf=AAAAAAAAAAADCQMaABhMS1NYRh0cRllbR0RRQG91cC5lcw--;nat=yes;pet=mst) Regarding my setup is more or less like this: kamailio.local.cfg: #!substdef "!MSTDOMAIN!mydomain.com!g" kamailio.cfg: modparam("corex", "alias_subdomains", "MSTDOMAIN") But in the cli: kamctl rpc corex.list_aliases { "jsonrpc": "2.0", "result": [ ], "id": 1319303 } I don't remember to have this issue when I was developing the mst integration. Either I missed it or can it be a regression? kamailio version is 5.6.4 at the moment. Any ideas? cheers Jon -- PekePBX, the multitenant PBX solution https://pekepbx.com

Just need some basic help
by Jere Cassidy 18 Jan '24

18 Jan '24

Hello! Thanks in advance for any help you can provide. I have a simple setup here and am struggling a bit with getting a final working solution. This is just a single direction flow from a SIP provider inbound to servers running HMPelements with CTI integration (sip endpoint). Essentially a different DN / dial number would go to a different backend server. There is no registration involved. The kamailio server therefore needs to sit between the SIP provider and the backend servers, it will be a NAT situation where private RFC1918 addresses will be used on the backend after the server receives it with public IP information. So that's it. What is the simplest way to accomplish this? If it would help - here's what ive done so far: For the Kamailio server, I have an AWS EC2 instance with a public IP bound/assigned to the main private IP. During troubleshooting, I've added another private IP to the NIC so that I could throw up another listener. I was thinking I'd need to accept the SIP on the first listener with the "advertise" directive. The second listener would not have an advertise directive so perhaps could be used to talk to the backends. I defined the WITH NAT and rtp proxy settings (pointing to the first listener below). The RTP Proxy daemon also knows about the y.y.y.y public address below. In the kamailio.cfg, I have a listener setup : listen=udp:172.24.40.28:5060 advertise y.y.y.y:5060 listen=udp:172.24.40.26:5060 then threw in a route(CMS) in the request route and created the following route block: route[CMS] { #check URI matches phone xxxxxxxxxx if (uri=~"^sip:\+1xxxxxxxxxx@") { rewritehostport("10.12.18.193:5060"); forward(uri:host, uri:port); exit; }; } I get the SIP delivered to the backend host! but the INVITE headers are stil pointing to public IPs and the SDP info is not adjusted to be a private IP as well - as follows: z.z.z.z = sip provider , y.y.y.y = public ip (aws ec2 ip). xxxxxxxxx = calling phone, ######## = called phone (matches routeCMS above) INVITE sip:+1##########@10.12.18.193:5060 SIP/2.0 Record-Route: <sip:y.y.y.y;lr> Via: SIP/2.0/UDP y.y.y.y:5060;branch=z9hG4bK28b7.56b42fdeec9f10cd13030b3711b16f4d.0 Via: SIP/2.0/UDP z.z.z.z:11000;received=z.z.z.z;rport=11000;branch=z9hG4bKQ2yQKgv7NtKQF Max-Forwards: 48 From: "" <sip:+1xxxxxxxxxx@z.z.z.z;isup-oli=0>;tag=tUF15gaNg6N6j To: <sip:+1##########@y.y.y.y> Call-ID: 9ee7e073-c7fc-46ac-a839-f3c77eaed903 CSeq: 78244364 INVITE Contact: <sip:mod_sofia@z.z.z.z:11000> User-Agent: 2600Hz Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, MESSAGE, INFO, UPDATE, REFER, NOTIFY Supported: path, replaces Allow-Events: talk, hold, conference, refer Privacy: none Content-Type: application/sdp Content-Disposition: session Content-Length: 278 X-FS-Core-UUID: 4e0b2928-d913-42c4-9809-f77a36d281be X-FS-Support: update_display,send_info P-Asserted-Identity: "" <sip:+1xxxxxxxxx@z.z.z.z> v=0 o=FreeSWITCH 1705572686 1705572687 IN IP4 z.z.z.z Thanks much!

Re: add a SIP custom header on a SIP response generated locally
by frédéric Gaisnon 18 Jan '24

Hi, Yes I've tried using append_to_reply() in several routes (tm:branch-failure, sl:local-response, tm:local-response, onreply_route, failure_route) but it was not applied. It works fine if a response is received or if it is generated by the configuration script but not if this response is locally generated by a kamailio module.

trigger different branch route on branch added with append_branch
by Benoit Panizzon 18 Jan '24

18 Jan '24

Hi List Imagine the following situation: Two Kamailio registrar proxies handling the same domain. Location Information synced via DMQ. So if a device registers we don't know on which of the two registrar proxies. Core proxy is dispatching calls to either one of those registrars. Core also performs AOR database lookup and adds an X- header telling which AOR the call is destined to. Registrar performs lookup of that AOR in the location database and routes the call to destination. Problem: The call could be routed to the the registrar which does not hold the active socket to that client. Solution: reg_fetch_contacts, cycle the contacts and append_branch if the contact has a local socket. Next Problem: I use a failure_route to sent the call to voicemail, if not registered, busy etc. This would trigger, if we have no local socket for the registration which is on the other registrar. So I have to find a way to send the call to the other registrar. I guess I can append_branch a branch pointing to the URI of the other registrar. This would then succeed in reaching the device. Also using the failure_route would work this way if we get a remote error from behind the other registrar or no registration at all. Next Problem: I use a branch trigger to remove undesired header I do not want to send to the customer. Now imagine that AOR has two contacts, one on registered on each registrar proxy. So I end up with two destinations added with append_branch to the destination set. One points to the device of the locally registered customer device, the other one points to the other registrar where to find the other device. I use a branch route trigger to remove the X- Headers towards the customer. But I need to X- Header containing the destination AOR to still be sent to the other registrar. Is there a way to trigger a branch route for only some of the destinations added with append_branch? Or to trigger different branch routes for different destinations in one set added with append_branch? Or am I doing this completely wrong and there is an easier way? ;-) Mit freundlichen Grüssen -Benoît Panizzon- -- 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 ______________________________________________________

tls.cfg and configuration
by Aymeric Moizard 17 Jan '24

Hi all, I'm using a central file to define my kamailio cfg configuration. First question: In my main kamailio.cfg, I use: include_file "kamailio-config.cfg" which contains: #!substdef "!MY_DOMAIN!kamailio.example.com!g" I would like to use the same in tls.cfg which is defined this way: modparam("tls", "config", "/etc/kamailio/tls.cfg") but I get: sr_cfg_parse(): tls.cfg:17:1: Unsupported option 'include_file' Would you advise some way to achieve my goal: ie, I would like only one file to edit my configuration options which would have an effect on both kamailio.cfg and tls.cfg Second question: Can someone confirm that #!substdef will also not have any effect when used in tls.cfg Thanks Aymeric -- Antisip - http://www.antisip.com

Not checking SRV records

Hi This may be a stupid question but after a couple of hours and some headache I can't see where the problem is. I'm trying to use SRV records to relay to different servers as I've done many many times before. But in this case I'm getting a 478 from kamailio and I see that it's not trying to resolve SRV. From the log: [core/dns_cache.c:527]: _dns_hash_find(): (fs.mydomain.dev(16), 1), h=632 [core/resolve.c:784]: get_record(): lookup(fs.mydomain.dev, 1) failed [core/dns_cache.c:761]: dns_cache_mk_bad_entry(): (fs.mydomain.dev, 1, 60, 1) [core/dns_cache.c:701]: dns_cache_add(): adding fs.mydomain.dev(16) 1 (flags=1) at 632 [core/dns_cache.c:2807]: dns_a_resolve(): (fs.mydomain.dev, 0) returning -7 [core/dns_cache.c:3176]: dns_srv_sip_resolve(): (fs.mydomain.dev, 0, 0), ip, ret=-7 uri2dst2(): failed to resolve "fs.mydomain.dev" :unresolvable A or AAAA request (-7) When doing tcpdump port 53 I see A record query but no SRV SRV records of course exist although they are not being checked. dns params in kamailio: dns_try_ipv6=no dns_retr_time=1 dns_retr_no=1 dns_use_search_list=no use_dns_cache=on use_dns_failover=on dns_srv_lb=on dns_try_naptr=no dns_sctp_pref=1 dns_tcp_pref=1 dns_tls_pref=1 dns_udp_pref=1 Same exact config in another server is working.

Internal DNS resolver
by Igor Potjevlesch 12 Jan '24

12 Jan '24

Hello! I have a quick question about the internal DNS resolver and cache embedded in Kamailio. Is the ability to add an entry with dns.add_a bypass the "real" DNS lookup? So, let's say that sip.example.com is publicly resolve alternatively with 1.2.3.4 & 5.6.7.8.9, if I do a dns.add_a to add my own sip.example.com with, alternatively, 127.0.0.1 and 127.0.0.2, will it work?

Clarification on usrloc timer_interval param and contact-expires event route.
by James Lipski 12 Jan '24

12 Jan '24

Hello, Just need a bit of clarification on the usrloc parameter "timer_interval". Let's say this is configured with a value of 60 seconds; every 60 seconds, will this delete all expired contacts in the location table between runs -- as in between runs it will queue up a list of expired contacts, remove them all after the 60 seconds has elapsed, then execute the event route "event_route[usrloc:contact-expired]"? Or does the event route execute as soon as the contact expires, independent from "timer_interval" timer? Thank you.

Timeout on forwarding REGISTRATION
by dries＠degendt.com 10 Jan '24

Hi all, My Kamailio server has been throwing a lot of errors during the manipulation and forwarding of registrations to my Asterisk server (192.168.96.97) using uac_req_send(); and t_relay() [core/tcp_main.c:1402]: tcp_do_connect(): connect 192.168.96.97:5060: (99) Cannot assign requested address [core/tcp_main.c:1399]: tcp_do_connect(): connect 192.168.96.97:5060 failed Cannot assign requested address When looking deeper into the code it appears that the errors are thrown when "tcp_async" is enabled. I've enabled this option a few weeks ago to make sure clients can REGISTER quickly. The parameter "tcp_reuse_port" is also set to yes. I'm suspecting that on busy moments, the destination can't be reached because no TCP connections are available. Is there any of the following parameters that I can adjust to prevent this issue? tcp_children = 25 disable_tcp = no tcp_max_connections = 63536 tcp_connection_lifetime = 3605 tcp_accept_aliases = no tcp_async = yes tcp_connect_timeout = 10 tcp_conn_wq_max = 65536 tcp_crlf_ping = yes tcp_delayed_ack = yes tcp_fd_cache = yes tcp_keepalive = yes tcp_keepcnt = 3 tcp_keepidle = 30 tcp_keepintvl = 10 tcp_linger2 = 30 tcp_rd_buf_size = 80000 tcp_send_timeout = 10 tcp_wq_blk_size = 2100 tcp_wq_max = 10485760 tcp_reuse_port=yes /* tcp_connection_match=1 */ open_files_limit=63536 A quick tcpdump doesn't show outgoing packet during the error events.

Hello, Any idea about the crash below? I found a ticket regarding to this, I made some comments and backtraces there also: https://github.com/kamailio/kamailio/issues/3635 Now this crash is very frequently, 3-4 times every day. There is a timer mechnism, where kamailio refreshes registrations towards asterisk automically to ensure continuous availability for mobile users. The crash exists 3-5 secs after this refresh process, but not always. Sometimes this process runs fine only CRITICAL logs appears (mentioned below) after it, but sometimes kamailio crashes during writing these CRITICAL logs.

Crash of Kamailio when using module http_async_client - function http_async_query, if module "tm.so" is not loaded (Kamailio 5.7.3)
by Chaigneau, Nicolas 10 Jan '24

Hello, When using http_async_query function, provided by module http_async_client: https://www.kamailio.org/docs/modules/devel/modules/http_async_client.html#… If module "tm.so" is not loaded, then immediately upon calling function http_async_query, Kamailio crashes: 9(3807541) CRITICAL: <core> [core/pass_fd.c:281]: receive_fd(): EOF on 8 0(3807527) ALERT: <core> [main.c:791]: handle_sigs(): child process 3807533 exited by a signal 11 0(3807527) ALERT: <core> [main.c:795]: handle_sigs(): core was generated 0(3807527) INFO: <core> [main.c:818]: handle_sigs(): terminating due to SIGCHLD Of course, I now know that I must load the module "tm.so". But I think it would be better to catch the issue when Kamailio starts, rather than crashing later on when trying to call http_async_query. What do you think ? Regards, Nicolas.

webRTC Test Client?
by Andy Newlands 03 Jan '24

03 Jan '24

Hi, I have a Freeswitch installation, fronted by a Kamailio proxy I would like to configure Kamailio to bridge SIP between webRTC clients and Freeswitch. The first issue I hit is how to set up a test webRTC client to make calls into Kamailio/FS. Can anyone point me to a simple webRTC client I can use to make test webRTC/SIP calls into my setup? Thanks BTW: I'm not JS experienced (I work with Python, C#, C/C++). Kind regards, Andy

Info: Next Kamailio World Conference - April 18-19, 2024, Berlin, Germany
by Daniel-Constantin Mierla 18 Dec '23

18 Dec '23

Hello, a short announcement to inform that the dates for next Kamailio World Conference have been set to April 18-19, 2024, the event to take place again in Berlin, Germany. It will be a different venue than the past editions, that one not being available. A pre-conference day is considered on April 17, 2024, but it is not yet known in what form and where. The conference is scheduled a bit earlier than the usual in the year because Germany hosts the Euro 2024 football championship during June-July 2024, making May very busy and harder to find adequate conferencing space in Berlin. The website and more details will be published soon.

Regretfully we were unable to process the URI
by Gavin Baumanis 18 Dec '23

18 Dec '23

Hi Everyone, Very new to SIP And to Kamailio Configuration / administration. I have a working AWS instance with Kamailio installed on it - and it works fine. We are creating a whole new environment and I have cloned the existing AWS EC2 instances. I have edited all the configs to ensure that they are using the correct DNS names and / or IP addresses. Otherwise the "configs" are identical. While attempting to call a SIP number, I get the following message, returned to the soft phone I am using (microSIP) *Regretfully we were unable to process the URI (479/SL)* I can also see the same error message in the console of the Kamailio server. I am hoping that this might mean something to someone enough - to suggest some troubleshooting steps, please. Thanks;

Proxy Inactivity and Kamailio Log Disruption Issue.
by satyaprakash ch 12 Dec '23

12 Dec '23

HI, Scenario: We possess 2 proxies and 2 registrar servers equipped with dmq functionality. Unexpectedly, one of the Proxy IP addresses was marked as inactive (FLAG: IP) in the dispatcher list, causing the proxy to cease responding. Simultaneously, Kamailio logs stopped recording any activity. Upon restarting the Kamailio service, the problem was resolved, and the proxy resumed normal operation, with the Flag changing back to AP (ACTIVE). The sudden occurrence of this issue is not clear, and due to the cessation of logs during the incident, we lack information for the investigation. Any suggestions on how to address this issue would be appreciated. And is this scenario happened to any one in your experience?

usrloc ka_mode - Flooding OPTIONS at same time?
by Benoit Panizzon 12 Dec '23

12 Dec '23

Hi We have reached 20000 registered CPE and start facing issues. Am I observing correctly that when ka_mode 4 is enabled, OPTIONS are send simultaneously to all registered CPE and not spread over the interval? They could be the cause very high pps peaks on network equipment? If so, is there a way to spread the ka options over time so they don't cause such high peaks? Or even better, is there a way to enable them for only some customers via a variable?

is_method_f(): cannot parse cseq header in xhttp:request event route?
by Benoît Panizzon 12 Dec '23

12 Dec '23

Hi all I use event_route[xhttp:request] on Kamailio 5.5 Every time a xhttp request is processed I get this log entry: ERROR: textops [textops.c:3541]: is_method_f(): cannot parse cseq header Almost identical config on Kamailio 5.6 does not show this error. Is that something that got fixed in 5.6? I see a change in the documentation, While 5.5 does not state $rm can be accessed, 5.6 states $rm contains the HTTP method. Or do I somehow leak the http request to somewhere I call is_method() on it after terminating the event route? How should the event_route[xhttp:request] properly be terminated? With 'return' or with 'exit'? -- 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 ______________________________________________________

Upgrade Minor versions
by Gavin Baumanis 11 Dec '23

11 Dec '23

Hi there, I have taken over a project that uses Kamailio. I am aware of what we use it for - I am just not sure on the how... apart from what I have read in the docs. We're currently running 5.4.2 and I'd like to upgrade to (at least) the latest 5.4 offering - as that seems as if it would be the easiest and safest option. So I am hoping I might get some direction, please - on the way forward for an upgrade. The documentation seems OK if you're upgrading minor versions... but I couldn;t find anything about upgrading patch versions. Thanks!

Updated: Online devel meeting on matrix - 15:00 UTC, Dec 5, 2023
by Daniel-Constantin Mierla 05 Dec '23

05 Dec '23

Hello, we should consider an online devel meeting sometime soon to summarize what was done at (and still needs to be done after) devel meeting in Dusseldorf and plan a bit the targets for next major release (5.8 or 6.0)? If considered useful, I propose Dec 5 at 15:00UTC (16:00 Berlin/Paris/Madrid/Rome), but we can also look for other dates as well. Topics to be discussed can be added at: - https://github.com/kamailio/kamailio-wiki/blob/main/docs/devel/irc-meetings… Pull requests can be made by users without git access. Cheers, Daniel PS: Previous announcement indicated the start time 14:30 UTC, this message changes it to 15:00 UTC - 30min later due to a constraint in availability of one of the Kamailio developers. -- Daniel-Constantin Mierla -- www.asipto.com www.twitter.com/miconda -- www.linkedin.com/in/miconda

Setting up Kamailio as SIP Proxy
by Saul Ibarra 04 Dec '23

04 Dec '23

Hi, I am needing some help setting up kamailio as a sip proxy between a provider(trunk) and a test pbx The trunk requires username&password and i would like to add that information to the request within the Kamailio proxy, so that the PBX can authenticate directly by IP (without username&password) through the Kamailio proxy. As a programmer with a limited background in SIP (currently learning), I am keen on understanding the intricacies of this setup at the SIP level. Could you please direct me to resources or documentation that covers scenarios similar to mine? Any help or guidance you could provide would be greatly appreciated. Thanks

tsilo dependency on usrloc
by Alex Balashov 03 Dec '23

03 Dec '23

Hi, I wanted to revisit the topic of tsilo dependence on the location service. All three ts_append*() functions have the following quality: - ts_append(): "performing a contact lookup on the table specified by the domain parameter." - ts_append_by_contact(): "the contact lookup is performed" - ts_append_to(): "performing a contacts lookup on the table specified by the domain parameter" Why is this extensive coupling to usrloc necessary? This makes it impossible to use `tsilo` in case of providing a push-notification add-on that front-ends an upstream registrar, requiring a kind of local shadow registrar or mid-registrar. What would make more sense is a generic mechanism that allows one to "drip" new contacts into an existing transaction, whether suspended or active. Kamailio has a mechanism to add more branches to an existing transaction, but the scope of that mechanism is only from *inside* the vantage point of the transaction in question. The key parlour trick of `tsilo` is that it permits dripping new branches into a *different* transaction. ts_append_to() almost does the trick, providing a target index and label, but it just insists on doing a registrar lookup to source the contacts. What is really wanted and needed for the downstream PN gateway use-case is a means of extracting contacts from incoming registrations (or other sources, potentially) without storing them in any fashion locally, without using or even loading usrloc, and just throwing them over the fence into a different transaction. Is this somehow possible by means other than tsilo? Am I overlooking something?
