Appending Branches Post Request Processing
by Knserbrave 08 Oct '24

08 Oct '24

Hi Community, Is it possible to append a branch to a transaction after the call is in a ringing state? Say a call comes in and an AOR only has two contacts. Branches are created to the contacts. A third comes in why the two are in the ringing state. Can we create a branch to the third?

t_append_branches() and "dead" tcp connections
by Ihor Olkhovskyi 04 Oct '24

04 Oct '24

Hello, Recently encountered an issue with tsilo (that is using t_append_branches), but not sure found a root cause. So, I have a call, but aparently there are some "dead" TCP connections in a "location" table modparam("usrloc", "handle_lost_tcp", 0) On call initialtion, INVITE's are sent to "last seen" location, but aparently there is no answer and I assume it's in a state "trying to establish TCP connection" Obviously, there is no "100 Trying" answer on any outgoing INVITE. Than, a REGISTER comes from a contact, that is supposed to be called. Usual ts_append("location", "$tu"); is called, but in the logs I see [REGISTER] tm [t_append_branches.c:208]: t_append_branches(): failure to add branches (-1) If there is an active TCP connection, branches are added as expected. I'm getting this only in a case of trying to establish a call to a "dead" TCP connection. What am I missing here or it sounds like a bug? -- Best regards, Ihor (Igor)

kamailio sending from udp non-listening port
by David Villasmil 04 Oct '24

04 Oct '24

Hello guys, i'm seeing something weird, and i'm working if you can let me know. I have a kamailio in AWS with a private IP listening on several sockets: Listening on udp: 10.1.2.36:5070 udp: 10.1.2.36:5080 udp: 10.1.2.36:5160 advertise 4.3.2.1:5160 udp: 0.0.0.0:5066 tls: 10.1.2.36:443 advertise sip.something.com:443 tls: 10.1.2.36:444 advertise sip.something.com:444 tls: 10.1.2.36:5061 When forwarding a udp invite received on 10.1.2.36:5080 to a public ip provider say on 8.8.8.8:5060, i'm forcing the outgoing socket with force_socket via 10.1.2.36:5160. But the outgoing invite does NOT use 5160, it uses some random port... Anybody knows why this might be? my problem is, that call goes to freeswitch... call is setup properly and connects fine. But 15 minutes later the end provider sends back a reINVITE, which freeswitch then sends TO THE RANDOM PORT kamailio used to send the INVITE... but by this time kamailio doesn't seem to even see the packet... help is greatly appreciated!

relay to voip provider / sip trunk / path?
by Linux Admin 03 Oct '24

03 Oct '24

Hi. I am using https://github.com/havfo/WEBRTC-to-SIP to have a web sipcaller. it uses kamailio + rtpengine + web sipcaller (jssip) right now it is working using internal kamailo account and can call to another sip. But I need to use websipcaller to call to voip provider. I tried to register on my voip provider, and use just outbound websocket proxy, but it not working giving 401 the config I am using is https://github.com/havfo/WEBRTC-to-SIP/blob/master/etc/kamailio/kamailio.cfg Please help adopt it to relay anything to external sip provider. I don't know what I need, relay, sip trunk or path module. kamailio configs are very hard for me to understand. So I need it just as websocket proxy to my voip provider, that doesn't support websocket. thanks!

app_lua parse multiple files
by iliusha.md＠gmail.com 03 Oct '24

03 Oct '24

I have a Lua script which is split into multiple files, like: /etc/kamailio/routing/ ├── main.lua ├── logger.lua └── db.lua On restart, Kamailio fails to start with an error: main.lua:2: module 'logger' not found:\n\tno field package.preload If I set multiple files in the modparam parameter: modparam("app_lua", "load", "/etc/kamailio/routing/main.lua") modparam("app_lua", "load", "/etc/kamailio/routing/logger.lua") I'm getting the same error. Is it possible to load multiple files, or is this a limit to a single file currently?

Heads-up: Clean-up of legacy modules in app_python3
by Richard Chan 01 Oct '24

01 Oct '24

HI kamailio users, There is a WIP PR on master (and targeting 6.0) to clean-up legacy modules on app_python3. https://github.com/kamailio/kamailio/pull/3986/commits/a9eb4b35b67b58893772… If you rely on pre-KEMI features (Core / Router / Logger / Ranks) can you chime in here. This work is also in preparation to enable the Kamailio module to use free-threading builds of Python. Regards Richard

Is it possible to sync a suspended transaction between two nodes using t_suspend() from the TMX module and DMQ (or similar module)? More specifically, can I suspend it on one node and resume the transaction on another in a cluster?

sys.exit() in app_python3s
by Denys Pozniak 26 Sep '24

26 Sep '24

Hello! I'm planning to rewrite a native Kamailio script in KEMI Python, and I want to understand the differences between app_python3 vs app_python3s in the context of using sys.exit(). My native script uses the exit function in deep nested route[] blocks quite a bit and would like to keep this logic in KEMI without using return codes on top (return -255) towards ksr_request_route() Using sys.exit() in app_python3s gives an error in syslog (although the interpreter does not crash and everything works correctly), in app_python3 no such error ERROR: app_python3s [apy3s_kemi.c:146]: apy3s_exec_func(): error exception occurred How safe is it to use sys.exit() in this case? -- BR, Denys Pozniak

Dear community: If someone runs this tutorial successfully for dockerized open5GS, please I appreciate it.

Re: [EXTERNAL] Re: SDP parsing fails when media stream is removed, there is no session-wide "c=" line and offending media stream omits all attributes
by Thomas Baumgartner 24 Sep '24

24 Sep '24

Hi Richard, thanks for your input. And i guess you are correct, when reading the sentence with the wording of the SDP RFC in mind attributes should only be "a=" lines. We will talk to the device vendor again with this new finding! Anyways, maybe it still makes sense to adjust the SDP parser for such scenarios, as it really doesn't make sense to require a "c=" line if the stream is being removed as you said. I will open an git issue aswell. Mit kommunikativen Grüßen I Best regards Thomas

SDP parsing fails when media stream is removed, there is no session-wide "c=" line and offending media stream omits all attributes
by Thomas Baumgartner 24 Sep '24

24 Sep '24

Hi, we have a problem with a device trying to send T.38 fax. During the T.38 ReInvite Kamailio fails to parse the SDP (via rtpengine_manage), and subsequently rtpengine is failing to do it's job. The problem seems to be that Kamailio is trying to find a media address, since there is no session-wide c= line present it goes to the media c= lines, but since the first media stream which was an audio stream is being removed (port 0) and can therefore omit all attributes (as per RFC 3264 8.2, or am i understanding this wrong?), the Kamailio SDP parser is failing, even if there is another c= line in the T.38 media stream. Here is the offending SDP from the ReInvite (IP changed): v=0 o=xmserver 1726638425 1726638427 IN IP4 169.254.1.1 s=xmserver t=0 0 m=audio 0 RTP/AVP 8 m=image 56002 udptl t38 c=IN IP4 169.254.1.1 a=sendrecv a=T38FaxVersion:0 a=T38MaxBitRate:14400 a=T38FaxFillBitRemoval:0 a=T38FaxTranscodingMMR:0 a=T38FaxTranscodingJBIG:0 a=T38FaxRateManagement:transferredTCF a=T38FaxMaxBuffer:200 a=T38FaxMaxDatagram:72 a=T38FaxUdpEC:t38UDPRedundancy And here is the corresponding log entry: <core> [core/parser/sdp/sdp.c:523]: parse_sdp_session(): can't find media IP in the message Can anyone confirm my findings? Is it possible to adjust the SDP parser for these kind of scenarios? Mit kommunikativen Grüßen I Best regards Thomas

t_next_contacts fails with 1 contact
by Igor Potjevlesch 24 Sep '24

24 Sep '24

Hello! I'm parsing 302 with, most of the time, multi contacts returned. I do it like this: get_redirects("*"); t_load_contacts(); and, finally, a test on !t_next_contacts(). This test fails when only one contact is present in 302. Is it the expected behaviour? From the documentation I understand that following t_load_contacts we must use t_next_contacts. If so, I believe that I shouldn't exit on !t_next_contacts() and do an additional test to see if there is, at least, one attempt to do toward the only contact returned? Thanks for your feedback.

Hi Community, Any advice on how to handle a Retry-After header locally without sleeping? I would like to suspend the transaction, schedule an event, wake up the transaction after the event timer triggers, and resume the transaction. I don't believe this is possible though.

Pseudo Variable containing 'path' of main branch? / How to compose $du manually with path?
by Benoît Panizzon 23 Sep '24

23 Sep '24

Hi List I want to be able to parallel branch a call to multiple registered locations / multiple different AOR. So using the registrar lookup() function can not be used. I loop through all required AOR with reg_fetch_contacts, those could be registered via a proxy and therefore require to use Path: $ulc(aor=>path) in this case, contains the path to that destination. On all 'additional' branches added with append_branch() I can set the path using $branch(path). But i struggle with the main aka first branch on which I directly set: * $ru * $fs * $du From the documentation, if I would use the registrar lookup() function, then $du would correctly be set respecting the path for all contacts on an AOR. But who do I build $du manually with what I find in $ulc(aor=>path) when not using lookup()? -- 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 ______________________________________________________

Kamailio not listening to SIP despite setup OK
by Sergio Charrua 21 Sep '24

21 Sep '24

Hi all! got a client with 2 Kamailio servers using Pacemaker/Corosync with a VIP. Kamailio is setup with dispatcher, and has been working since 2018. This previous week, client migrated from a Cisco ASA firewall to a Fortinet F5 firewall. One of the Kamailio server is, apparently, working fine, receiving SIP invites and processing them correctly. When moving the VIP to the second Kamailio node, Kamailio is ignoring any SIP message that is not OPTIONS, despite configuration (kamailio.cfg) being exactly the same as in the node #1. Also, note that using SNGrep, we can see clearly that SIP messages are reaching the server, but Kamailio is just not processing any INVITE. In fact, I added an output to log file right at the very beginning of the main route and the line is added to log file ONLY if the SIP message is OPTIONS. When the SIP message is INVITE, nothing is processed on Kamailio's side. The listen parameter is set to 0.0.0.0 port 5060 and advertised IP set to the Public IP. Again, the main route is only : route{ xlog(. ......); } Kamailio version is 5.1.6 (old, I know....) but it has been working since Dec 2018! What could be the issue?! Why only OPTIONS are being , somehow, recognized by Kamailio and all other SIP messages just ignored? Also, to add some more weirdness to the mess, connecting an Asterisk server on the same network, and sending a call to Kamailio node #2, it works!! SIP messages of any kind are processed correctly by Kamailio on node #2. So, why doesn't it work with SIP messages received via Public IP address, even though the messages reach the server correctly (confirmed using SNGrep) ??? I spent 5h this afternoon trying to understand what is wrong, but I'm stuck .... and no clue so far, apart from suspecting of the new Gateway, which I have no access to configurations.... but if OPTIONS are received & processed OK, it wouldn't make sense that received INVITES would be ignored by Kamailio, right? Atenciosamente / Kind Regards / Cordialement / Un saludo, *Sérgio Charrua*

Handling SIP Contact Header Changes and ACK Routing Issues
by XPTO 21 Sep '24

21 Sep '24

Hello community! I would like to ask for your help in solving a case. I thank you in advance for any collaboration. I have the following setup: - *Asterisk (internal)* → *Kamailio (Proxy)* → *SIP Provider (PSTN)* Both Asterisk and Kamailio are under my responsibility. *Problem:* When I initiate a call from Asterisk, I use Kamailio as the *outbound proxy*. The *INVITE* is sent to the SIP provider, and the dialogue proceeds normally until the provider responds with a *200 OK*, indicating the call was answered. However, the *200 OK* received from the provider contains a modification in the *Contact* header, introducing a new IP address into the dialogue. Presumably, this new IP is where the subsequent *ACK* should be sent. The issue arises when Kamailio receives this *200 OK*: it overwrites the *Contact* field, replacing the received IP with its own LAN IP, used for communication with Asterisk. As a result, Asterisk sends the *ACK* back to Kamailio, which, instead of forwarding it to the new IP from the *Contact* in the *200 OK*, sends it to the SIP provider at the same address used for the initial *INVITE*. Since the *ACK* does not reach the IP expected by the provider (the new IP introduced in the *Contact*), the provider continues to send repeated *200 OK* responses, until the call is disconnected due to a timeout, as a valid *ACK* was never received. I looked for conceptual answers in *RFC 3261* to support my conclusions, but I couldn’t clearly relate the information there to the behavior observed in this scenario. *Key Questions:* 1. *Should Kamailio forward the ACK to the new IP provided in the Contact header of the 200 OK?* 2. *Is the SIP provider correct in expecting the ACK to be sent to a different address from the original one used in the INVITE?* 3. *How can I configure Kamailio to ensure the dialogue proceeds correctly and the ACK is sent to the correct IP?*

Active/Active Registrar Design
by Knserbrave 20 Sep '24

20 Sep '24

Hi Community, Is it a common experience for architects to encounter issues with active/active registrar designs? Specifically, when clients are the UAS of a dialog? Some user agents accept INVITEs from any source once registered while others are not as accepting. There are ways around this using 302 redirect, but there seem to also be ways per RFC to signal trusted nodes to clients. RFC 3608 seems to be an excellent way to address this issue by communicating trustworthy nodes to the client upon registration. However, the Service-Route header seems to give options to the client rather than communicate trust. No where in the RFC does trust seem to be mentioned in its design, however one could imply it should be deduced by the presence of a Service-Route header. Nonetheless, even if it should communicate trust, it doesn't seem to do so in all cases so the more logical approach to active/active is signal via a 302 redirect where the registration lives, handling INVITE transactions on the server-side instead of client-side. I'm curious to hear if there is any advice on from the community overcoming trust issues with user agents in an active/active registrar design.

Accessing User-Agent from usrloc at runtime.

Hi Kamailio community. There are a few fields in the usrloc cache I am interested in accessing at runtime to influence routing decisions. I can use SQLops to achieve the same functionality, however I'm interested in minimizing DB operations. I would like to know if there is a generally accepted approach to retrieving this information from the memory-hosted usrloc cache rather than dipping into the database.
