Error opening Kamailio's FIFO /run/kamailio/kamailio_rpc.fifo
by matilopi17＠gmail.com 01 Nov '24

01 Nov '24

Hello, This is kamailio version 5.8.2 and we`re having this issue every now and then. The error displayed is: ** ERROR: Error opening Kamailio's FIFO /run/kamailio/kamailio_rpc.fifo ** ERROR: Make sure you have loaded the jsonrpcs module and set FIFO transport parameters The problem is that the FIFO file /run/kamailio/kamailio_rpc.fifo doesn't exist, even though the "jsonrpc" module is in the Kamailio configuration, and the file is created when Kamailio service is restarted. But as mentioned, after few days the issue is repeated. I`ll appreciate any suggestion or advice of what I should check. Thank you!

Failed to parse the R-URI with topoh enabled
by Ale 29 Oct '24

29 Oct '24

Hi All, I think I have a problem with topoh, but I can't identify it. Kamailio 5.6.6, used as a stateless proxy, receives a 487 from a phone and propagates it correctly. Next comes the ack that should be forwarded back to the phone, but instead it doesn't forward it and produces the following error "pv_get_ruri(): failed to parse the R-URI" The error is generated by xlog("...$ru from $fu...\n"") as first line of request_route. If I disable topoh everything works perfectly.Topoh is only configured with mask_key only. Furthermore, not all phones generate this problem, at the moment there are some snoms. ACK sip:user@phone_ip:2048;line=kkqgarrj SIP/2.0 Via: SIP/2.0/UDP proxy_sip_ip;branch=z9hG4bK2ec.e7126a3134bef9d974f57dd43ebd4ea2.0 Route: <sip:kamailio_ip:5060;lr;received=sip:phone_ip:2048> Max-Forwards: 66 From: <sip:111111111@sip.example.com>;tag=pDc1BQ0B57Ujj To: <sip:user@sip.example.com>;tag=vslvowy4y2 Call-ID: 40a6c905-c0c8-4c20-b3f7-397b3fce58b6 CSeq: 90285584 ACK Content Length: 0 There is no difference between the ACK of the snom and other phones that work. The only difference I noticed is that the snom 487 contains Contact field in the header. Any suggestions? Thank you

How to handle e2e ACK with t_check_trans()
by Benoit Panizzon 28 Oct '24

28 Oct '24

Hi List To correctly route ACK belonging to a transaction (totag) the example code does: if ( is_method("ACK") ) { if ( t_check_trans() ) { route(RELAY); exit; } else { xlog("L_INFO", "$cfg(route): $rm NOT loose route NO transaction found DROP\n"); exit; } } Unfortunatels I fear that in a parallell forking scenario, the transaction is remove from memory as soon as the first 'negative' ACK is being processed so that the end 2 end ACK to the 200 OK of the branch that connected the call, never makes it through. I attempted to increase wt_timer to 10000 to have the transaction stay around 10 seconds but that does not solve the issue. I read that t_check_trans()'s result shall be considered more as a hint than as a confirmation of an existing transaction. Is there a clean / secure way to process e2e ACK and make sure they belong to a transaction? Or can I just safely remove the t_check_trans() call and route any ACK with a totag?

Dealing with flood of invalid SIP messages
by mayamatakeshi 27 Oct '24

27 Oct '24

Hi, I was going through some old company tickets that I am assigned to and found a case when possibly an attacker flooded our kamailio server with invalid sip messages like this: 2019-04-27T20:14:05.533554+09:00 IPX051 /usr/local/src/git/sip-router/kamailio[1732]: ERROR: <core> [parser/msg_parser.c:714]: ERROR: parse_msg: message=<[F#016sD#026Z<8D>97<F8><B5>;<A9><E7>-<D2>(<E2><F6> v;/#021k\<CC>8<B1>λ<F4>#004M<B6><BE><EC>#035#003<94><E1>=<A0><FF><E3><AF>Kwzr<8B>A#036B<D7>#027#023cu<82>Y<D4>#037<FB><AC>S_<C4>Qg<AB><DE>F<88>I#006<8C><FA><F4>~#y3G<C7>H<80>b<BC><AD>#035<89>#002<DB><C8>#001U<9E>#007<CB><F9>nT<E5><EE><8E><F1>#0144> At that time we manually banned the IP. But it would be helpful to have this done automatically by fail2ban. So I was thinking this log should include the src IP address. I looked at the latest kamailio commit and core/parser/msg_parser.c does this log the same way so I was thinking in opening an issue for this. But maybe this should be dealt with differently. Any ideas?

parallel forking: how to fix 183 g711 then 200 ok g722?
by Benoit Panizzon 21 Oct '24

21 Oct '24

Hi Gang Parallel forking situation. A => B A => C A invites with g711,g722 which is forked to B and C B reports ringing by sending 183 + SDP g711 C report 180 ringing. C establishes connection 200 OK + SDP g722 https://www.rfc-editor.org/rfc/rfc3261.html#page-78 o If the initial offer is in an INVITE, the answer MUST be in a reliable non-failure message from UAS back to UAC which is correlated to that INVITE. For this specification, that is only the final 2xx response to that INVITE. That same exact answer MAY also be placed in any provisional responses sent prior to the answer. The UAC MUST treat the first session description it receives as the answer, and MUST ignore any session descriptions in subsequent responses to the initial INVITE. Now we run into the situation in which A received the 183 g711 and being RFC compliant, dropped the 2nd SDP from the 200 OK. => No audio! Has anyone encountered this situation and found a nice solution? Like generating an UPDATE or RE-INVITE towards A to change the codec in an RFC compliant way after the call is established? Or is the only solution to remove all codecs except the required g711a one when more than one contact are registered on an AOR?

Statically Linking Multiple Modules Compile Error

$hdr behaviour using jansson+http_connect
by Sergio Charrua 19 Oct '24

19 Oct '24

Hi all! My team and I are finalizing implementation of STIR/SHAKEN. The flow has been simplified and is something like: Call comes from SBC to Kamailio, Kamailio makes an HTTP request to a REST API, response is received by Kamailio (5.8.2) and depending on the response, it replies back to SBC with a SIP 300 Multiple Choice of a SIP 4xx error, denying the call. The INVITEs received by SBC may or may not contain the Identity header. On Kamailio side, the following code gets the required headers to build the JSON object sent to REST API: route[HANDLE_STIRSHAKEN] { if (!is_method("INVITE")) { return; } $var(requestTime) = $utimef(%s); $var(ruri) = "$ru"; #request URI $var(from) = "$hdr(From)"; #$fU From header $var(to) = "$hdr(To)"; #$tU; To header $var(contact) = "$hdr(Contact)"; #Contact header $var(callID) = "$ci"; # Call ID $var(identity) = "$hdr(Identity)"; # Identity header jansson_set("string","from" , $var(from) , "$var(post)"); jansson_set("string","to" , $var(to) , "$var(post)"); jansson_set("string","r-uri" , $var(ruri) , "$var(post)"); jansson_set("string","contact" , $var(contact) , "$var(post)"); jansson_set("string","call-id" , $var(callID) , "$var(post)"); jansson_set("string","identity" , $var(identity) , "$var(post)"); http_connect("api1", "/stsh", "application/json","$var(post)","$var(result)"); xlog("L_DEBUG", "HANDLE_STIRSHAKEN - Result = $var(result)\n"); [... do some other irrelevant stuff ...] } The usual INVITE is similar to this: INVITE sip:+33142XXXXXX@10.242.XXX.YYY:5060;user=phone SIP/2.0 Via: SIP/2.0/UDP 10.240.AAA.BBB:5064;branch=z9hG4bK+30f178b47ee25dd589f986ed7402b4eb3+sip+6+a64eb889 From: "+493XXXXXXX" <sip:+493XXXXXXX@10.240.AAA.BBB ;user=phone>;tag=10.240.AAA.BBB+6+ffe686f8+614d17a3 To: +33142XXXXXX <sip:+33142XXXXXX@10.242.XXX.YYY> CSeq: 1 INVITE Expires: 180 Content-Length: 234 Call-Info: <sip:10.240.AAA.BBB:5064>;method="NOTIFY;Event=telephone-event;Duration=2000" Supported: timer, 100rel Contact: <sip:+493XXXXXXX@10.240.AAA.BBB:5064;user=phone> Content-Type: application/sdp Call-ID: 0gQAAC8WAAACBAAALxYAAHRfFdrMLbnN/iMYu2NTT6kvhuhZAFl7MG1V2ozJLUcXg9dxbyQZ/PtoswtdHtcv9g--(a)10.240.AAA.BBB Min-SE: 90 Session-Expires: 90;refresher=uac X-dtmf: 5 P-Asserted-Identity: "+493XXXXXXX" <sip:+493XXXXXXX@10.240.AAA.BBB> Accept: application/sdp Accept: application/dtmf-relay Max-Forwards: 66 Allow: INVITE,CANCEL,BYE,ACK, INFO Identity: dGhpcyBpcyBzb21lIGR1bW15IGJhc2U2NCBlbmNvZGVkIElkZW50aXR5IGhlYWRlcg==.eW91IHdvdWxkIG5vdCBleHBlY3QgbWUgdG8gbGVhdmUgdGhlIHJlYWwgdmFsdWUgaGVyZSByaWdodD8=.dGhhbmtzIGZvciB5b3VyIGNvbXByZWhlbnNpb24=;info=< https://someURL.com/with/some/parameter;sc697295b.cer>;alg=ES256;ppt=shaken P-Origination-Id: 23A16F8B-F9AB-4536-9884-85C96EF3B964 P-Attestation-Indicator: C has-sdp: present [SDP stuff] (I have replaced some of the values for obvious reasons). - SBC is sending every 70 secs 2 automatically generated INVITEs to kamailio - 1st call contains the Identity header, the other call does not contain Identity header. - Both calls have different Call-IDs and different FROM and TO values, so they are different calls and can be perfectly found in logs as separated calls - Kamailio receives each call and extracts headers, as shown in code above, and sends the JSON request to HTTP REST API Here is the weird part.... every now and then, completely random, the JSON object request sent to the HTTP REST API contains an Identity value, supposedly extracted from the SIP header **but** the SIP message captured in SNGrep doesn't have **any* I*dentity header!! In fact, in the kamailio logs, where I sent the header values extracted from INVITE, the identity is empty! BUT the JSON object has the identity set with value. And the worst part is that, when this issue happens, the value of the Identity set in JSON belongs to a completely different call that was processed a few minutes before ! So I suspected about some Caching behaviour on the http_connect function and added the following lines before sending the JSON to REST API: if ( is_present_hf("Identity") ) { jansson_set("string","identity",* $var(identity),* "$var(post)"); } else jansson_set("string","identity", "", "$var(post)"); forcing the identity property of the JSON to an empty string, but this did not work either! I even added a new property which is the current timestamp making sure every request was unique, and that did not work either! The only way I could make it work was replacing the above lines using these lines: if ( is_present_hf("Identity") ) { jansson_set("string","identity", *(a)hf_value2.Identity*, "$var(post)"); } else jansson_set("string","identity", "", "$var(post)"); So, instead of using $hdr(Identity) , Kamailio extracts the Identity header using @hf_value2.Identity Question: why is this behaviour? Could this be a bug somewhere? Atenciosamente / Kind Regards / Cordialement / Un saludo, *Sérgio Charrua*

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)

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

Sync Suspended Transaction
by Knserbrave 30 Sep '24

30 Sep '24

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. Web page of OPEN 5GS: [image: image.png] The APNs were created in the docker_host:8080/docs [image: image.png] When i ran the command: docker compose -f srsenb.yaml up - d && docker container attach srsenb [image: image.png] [image: image.png] I created 2 APNs on the phones, but when I select one of them (internet), I have access to the Internet.

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
