RTC DevRoom at FOSDEM 2025
by Daniel-Constantin Mierla 21 Nov '24

21 Nov '24

Hello, FOSDEM'25 will host again a RTC DevRoom during the afternoon of February 1, 2025 (Saturday) -- more details and the call for presentation can be read at: - https://lists.fosdem.org/pipermail/fosdem/2024q4/003584.html I am not sure if I can participate (chances are more towards no, than to yes), but if anyone considers to go to the event, it will be good to submit a proposal to cover a bit Kamailio as well (it doesn't have to be entirely about Kamailio). Note that FOSDEM imposes a strict deadline this time for submissions (Dec 1, 2024), thus is no much time left. Should anyone in these groups plans to submit a proposal, let us know, so the others have an idea about it. Cheers, Daniel -- Daniel-Constantin Mierla (@ asipto.com) twitter.com/miconda -- linkedin.com/in/miconda Kamailio Consultancy, Training and Development Services -- asipto.com

TM-Module, ignoring
by Christian Berger 19 Nov '24

19 Nov '24

Hi, we would like to replicate a SIP-message ("REGISTER" in our case) to a set of nodes for further asynchronous processing. The message is already processed on the local Kamailio. We thought about using the tm-module in conjunction with the dispatcher module so we can reliably forward the message. This seems to work, however we get a new problem: Kamailio forwards the response it gets from those nodes. When we drop the response in the reply_route, it gets dropped before TM can see it. When we drop the response in the on_reply_route, it still will be forwarded. (adding or removing a header here works, however) $du is set to $null. Is there any clean way to suppress that response being forwarded back to the original requester?

Not able to use SRTP - from client to proxy
by Sajid Khan 18 Nov '24

18 Nov '24

Im using the module RTPengine. im having issues when ever i try to do a call using SRTP im using microsip i have checked the SDP everything ok. But when ever i place the call it gets rejected. if i disable SRTP then the calls work if (!rtpengine_offer("replace-origin replace-session-connection ICE=force RTP/SAVP RTP/AVP")) { I only need to encrypt client -> proxy from proxy -> asterisk should be plain rtp i hope someone can help me out thank you. The log in rtpengine shows this [1731055305.417896] ERR: [2a721ebf2c73414ab8e739d7bde912f9//1 port 14124]: [srtp] SRTP output wanted, but no crypto suite was negotiated

Hi, I have recently migrated from Kamailio 5.2.5 to Kamailio 5.5.7. After a migration, the Kamailio crashed. Also, there were a lot of errors and warnings.

Pua PUBLISH method over xmlrpc/jsonrpc
by dries＠degendt.com 18 Nov '24

18 Nov '24

Hi all I've installed a (pretty old) presence_dfks module that allows setting the presence using the following command: kamctl fifo pua_publish sip:1000@10.10.99.254 3600 as-feature-event application/x-as-feature-event+xml . . . "<?xml version='1.0' encoding='ISO-8859-1'?><ForwardingEvent><device><notKnown/></device><forwardingType>forwardImmediate</forwardingType><forwardStatus>true</forwardStatus><forwardTo>1234</forwardTo></ForwardingEvent>" The "pua_mi" module was however removed in Kamailio and jsonrpcs/xmlrpcs are supposed to be an alternative. I've tried both the following calls, but neither does recognize the pua_publish/pua.publish as a valid method. Attempt with jsonrpc: curl -H "Content-Type: application/json" -X POST -d '{"jsonrpc": "2.0", "method": "pua.publish", "params": [""], "id":1}' https://sbctest.tel.redacted.xx:5061/RPC/ ERROR: jsonrpcs [jsonrpcs_mod.c:1422]: ki_jsonrpcs_dispatch(): method callback not found [pua.publish] Attempt with xmlrpc: curl -H "Content-Type: text/xml" -X POST -d '<?xml version="1.0" ?><methodCall><methodName>pua_publish</methodName><params><param><value><string>sip:jh@sbctest.tel.redacted.xx</string></value></param><param><value><string>7776000</string></value></param><param><value><string>as-feature-event</string></value></param><param><value><string>application/as-feature-event</string></value></param><param><value><string>.</string></value></param><param><value><string>a.1481534683.13958.6.7</string></value></param><param><value><string>sip:127.0.0.1:5080;transport=tcp</string></value></param><param><value><string>P-Flags: 0</string></value></param><param><value><string>Messages-Waiting: yesMessage-Account: sip:jh@sbctest.tel.redacted.xxVoice-Message: 2/0 (0/0)</string></value></param></params></methodCall>' https://sbctest.tel.redacted.xx:5061/RPC/ <?xml version="1.0"?> <methodResponse> <fault> <value> <struct> <member> <name>faultCode</name> <value><int>500</int></value> </member> <member> <name>faultString</name> <value><string>Method Not Found</string></value> </member> </struct> </value> </fault> Anyone who had some luck in this matter?

SIP NOTIFY over TLS fails
by dries＠degendt.com 15 Nov '24

15 Nov '24

Hi all I've installed a custom presence_dkfs module (https://github.com/tombeard/presence_dfks) in an effort to make our Grandstream devices (connected over TLS) display a server set callforward using Broadsoft's Device Feature Key Sync. The module was installed succesfully, but it appears that the NOTIFY upon SUBSCRIBE cannot be sent over TLS. This part seems to use the default presence module however so I'm taking my chances here to ask for some advice. I have already disabled verify_certificate in tls.cfg. The "dst addr: 193.19x.x.x:0" does seem to have an incorrect port as I should expect 5061? INFO: {1 600000 SUBSCRIBE 319937814-5062-3(a)BHC.DA.GB.CD} presence [notify.c:1744]: send_notify_request(): NOTIFY sip:544460@sbctest.tel.redacted.xx via sip:544460@172.30.61.23:5062;transport=tls on behalf of sip:544460@sbctest.tel.redacted.xx for event as-feature-event : 319937814-5062-3(a)BHC.DA.GB.CD ERROR: tls [tls_server.c:1312]: tls_h_read_f(): protocol level error ERROR: tls [tls_util.h:50]: tls_err_ret(): TLS connect:error:14094410:SSL routines:ssl3_read_bytes:sslv3 alert handshake failure (sni: unknown) ERROR: tls [tls_server.c:1316]: tls_h_read_f(): src addr: 172.30.61.23:5062 ERROR: tls [tls_server.c:1319]: tls_h_read_f(): dst addr: 193.19x.x.x:0 ERROR: <core> [core/tcp_read.c:1526]: tcp_read_req(): ERROR: tcp_read_req: error reading - c: 0x7f6d55b4b360 r: 0x7f6d55b4b488 (-1) Your advice is most appreciated!

dlq_req_within() usage for 3pcc-style reinvite media setup
by Alex Balashov 14 Nov '24

14 Nov '24

Hi, I am trying to use dlg_req_within() for a 3pcc-style call setup, to set up media via a reinvite: 1. Store original SDP offer from caller in $dlg_var()s; 2. Later, after e2e ACK is processed for initial INVITE transaction, send reinvite to callee using dlg_req_within(). I call rtpengine_offer() and feed it the original SDP offer (via read_sdp_pv modparam), and take the RTPEngine-transformed SDP and feed that to dlg_req_within(): dlg_req_within("callee", "INVITE", "application/sdp", "$var(sdp_from_rtpengine)"); 3. I have found that event_route[tm:local-response] does not allow me to capture the 200 OK / SDP answer to this reinvite; it is internally absorbed. However, it is possible to arm an onreply_route in event_route[tm:local-request], to receive the 200 OK: event_route[tm:local-request] { if(method == "INVITE" && has_body("application/sdp")) t_on_reply("REINVITE_REPLY"); } 4. My intent is for this reinvite reply handler to set off a reinvite to the caller side: onreply_route[REINVITE_REPLY] { if(method == "INVITE" && has_body("application/sdp") && t_check_status("200")) { ... $var(rtpengine_use_this_sdp) = $rb; rtpengine_answer("..."); dlg_req_within("caller", "INVITE", "application/sdp", "$var(sdp_from_rtpengine)"); } This ensures proper relay symmetry. Otherwise, the caller will continue to send RTP to the previous upstream endpoint of the call, prior to any reinvite. However, dlg_req_within() doesn't work in this later context, even though the documentation says it can be used from ANY_ROUTE. Kamailio doesn't complain, there is no error. It just doesn't initiate a reinvite to the caller. I considered the possibility that this may be because the calling scope is that of a pending reinvite transaction to the callee, but there is no obvious way to defer that into the future. If I send it to an async task worker, the transaction scope required for dlg_req_within() to know which dialog it's operating on will be lost. Any ideas appreciated, and thank you in advance! -- Alex -- Alex Balashov Principal Consultant Evariste Systems LLC Web: https://evaristesys.com Tel: +1-706-510-6800

Experimenting with KEMI for the first time, I ran into a few issues and hoping someone has feedback. kamailio 5.8.3 In the following python example, 'if ksr.is_method("ACK"):' should never be reached. Below is debug. if not ksr.siputils.has_totag(): ksr.info("has to tag") sys.exit() if ksr.is_method("ACK"): if ksr.tm.t_check_trans(): ksr.relay() sys.exit) else: sys.exit() ksr.sl.send_reply(404, "Not here") sys,exit() .....

Tell topos to create 'duplicate' route header from rr header with same ip
by Benoit Panizzon 14 Nov '24

14 Nov '24

Hi Gang I'm having another go with a dedicated kamailio running topos to replace a B2BUA SBC. I came across this situation: Server Topology: Kamaiolio SBC (topos) <=> Kamailio Registrar <=> Kamailio Router (DLG + CDRS) Core IP Address 10.0.0.1 Registrar IP 10.0.0.2 Two different CPE are registered on Registrar via SBC One CPE is calling the other CPE So the path the call is taking is: CPE A => SBC => Registrar => Core => Registrar => SBC => CPE B Invite A => B goes through, no issue. 180 Ringing, required 100rel B => A requires the route to be recorded therefore contains 3 record route statements: Record Route: <sip:10.0.0.2;lr> Record Route: <sip:10.0.0.1;lr> Record Route: <sip:10.0.0.2;lr> To ensure answer will get route back to the registrar => core => registrar and then the contact pointing to the SBC with topos to restore the last hop. Ringing B => A works as expected and is answered by A with PRACK. topos would now need set Route: in this PRACK message, according to the received Record Route Header. Unfortunately I fear Topos 'removes' the routes with duplicate host ip. I only get: Route: <sip:10.0.0.2> Route: <sip:10.0.0.1> Causing the Core not to be able to route the PRACK back to the registrar. To test, which line is being dropped, I added an mark to each one and determined the 3rd Record Router is being dropped by topos, probably considered a duplicate. I found no setting of the 'do not perform record route header dupe detection'. Interestingly, when I look at the database field topos_d.b_rr all three entries are present in the correct order. Has anyone come over the same issue and found a solution? Maybe related to: https://github.com/kamailio/kamailio/issues/3778 ?

Last line of onreply_route (drops reply)
by James Browne 11 Nov '24

11 Nov '24

Hi all I noticed, in my config, that if the last line of the reply_route is a function that does not succeed, then the SIP response is not relayed and kamailio throws an error. I've searched documentation to indicate why this might be, but I can't find anything, so this looks to me like a bug. I use 5.8.1 for testing. Here's a sample config that shows what goes wrong. #################### #!KAMAILIO listen=udp:203.0.113.57:5060 debug=1 loadmodule "textops" request_route{exit;} reply_route{remove_hf_re("^X-Custom");} #################### Here's a sample SIP message that works. When I send this to udp:203.0.113.57:5060, kamailio relays it. #################### SIP/2.0 200 Testing Via: SIP/2.0/UDP 203.0.113.57:5060;branch=z9hG4bK-d8754z Via: SIP/2.0/UDP 198.18.0.157:5060;branch=z9hG4bK-d8754z T: <sip:c@s>;tag=676fbf45 F: <sip:c@s>;tag=676fbf45 X-Custom: lkjdfl i: testing-XXX CSeq: 1 INFO l: 0 #################### If I then remove the X-Custom header field from the SIP reply and try again, the message does not get relayed and I see this in the log. 5(1356) WARNING: <core> [core/receive.c:605]: receive_msg(): error while trying onreply script If I put a log command after the remove_hf_re(), then the message gets relayed. It looks like the reply_route always fails if the last function is not successful. Is this normal or is it a bug? James

Question regarding error message "failed to add new socket to the fd list"
by Floimair Florian 11 Nov '24

11 Nov '24

Hi! We have recently had issues with one of our Production Kamailios. When those happened, the log was filled with the following message: CRITICAL: <core> [core/tcp_main.c:4528]: handle_new_connect(): failed to add new socket to the fd list Now I wonder what the best approach is to prevent this. We are using TCP/TLS only and I think this might be related to the file ulimit, but I am not sure about that. Shared memory is set to 512MB Can you give me a hint on what to look for? Thank you very much! P.S.: Sorry, I accidentally replied to a previous post of a different topic before which is totally unrelated (I think I should stop working for today 😉) FLORIAN FLOIMAIR Software Development - Symphony Cloud Services Commend International GmbH Saalachstrasse 51 5020 Salzburg, Austria [signature_2072127332] commend.com LG Salzburg / FN 178618z

apt-key deprecation
by tom＠tomlynn.com 11 Nov '24

11 Nov '24

When I look at the debian repositories maintained by the project, there are instructions to import the public key of the repository for apt using this command: wget -O http://deb.kamailio.org/kamailiodebkey.gpg | sudo apt-key add - which results in: Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)). gpg: no valid OpenPGP data found. Is there an alternate method that can be posted in the repository that will get better results? Thank you, TL

Draining TCP/TLS SIP sessions from Kamailio and media sessions from RTPEngine
by Evgenii Buchnev 07 Nov '24

07 Nov '24

Hi Dear Community, Would appreciate your input into where to look further to explore my options and would be good to learn your experience with the following. There are many active-active kamailio nodes behind tcp load balancer. On the same VM with each Kamailio there is an instance of RTPEngine to manage Media/Transcoding/Etc for that Kamailio. This scales UP easily - new nodes just added behind tcp load balancer. To be able to scale down and/or update node configuration - I'd like to be able to drain sessions/calls properly and pass any active calls from current Kamailio and RTPEngine to other nodes. DMQ is not yet in place, although it's planned. What would be proper ways of migrating RTP sessions to other RTPEngines? Caveats? Also wonder how properly a tcp/tls based SIP session can be passed to another Kamailio? Thank you in advance for your input. Evgenii Buchnev

Roadmap to v6.0.0 - the next major release
by Daniel-Constantin Mierla 07 Nov '24

07 Nov '24

Hello, about 8 months since the last major release v5.8.x, therefore it is the time to plan a bit the next steps for getting v6.0.0 out. The Kamailio Developers Meeting is schedule in Dusseldorf, Germany during November 19-20, 2024, where we expect to push out a consistent number of updates. Then maybe we can wait for another 2 weeks or so to settle down/finish those updates. After that, if no other new features are planned by developers in short term, we can enter the testing phase, so the new major version can be released during the second part of January 2025 or first part of February 2025. Therefore, if you have new features under development that might require more than 1-1.5 months from now, and you want to get them in v6.0.0, let us know to plan properly. Other time lines suggestions to get to v6.0.0 are also welcome!

SNMP setup

Hi all! I am having difficulties setting up SNMP, and mostly to figure out if what I have setup is correctly configured. This is what I have on Kamailio (5.8.2), which is set as stateless and as a redirect server (simply put, it receives INVITE from SBC, gets a route from routing services, modifies Contact header, and replies to SBC with 300 Multi Choice with new contact header): loadmodule "db_mysql.so" loadmodule "db_cluster.so" loadmodule "http_client.so" loadmodule "jsonrpcs.so" loadmodule "kex.so" loadmodule "corex.so" loadmodule "sl.so" loadmodule "pv.so" loadmodule "maxfwd.so" loadmodule "textops.so" loadmodule "xlog.so" loadmodule "sanity.so" loadmodule "jansson.so" loadmodule "snmpstats.so" loadmodule "file_out.so" loadmodule "ctl.so" loadmodule "permissions.so" loadmodule "xhttp.so" loadmodule "xhttp_rpc.so" # ---- SNMP Stats params ---- modparam("snmpstats", "sipEntityType", "proxyServer") modparam("snmpstats", "sipEntityType", "redirectServer") modparam("snmpstats", "sipEntityType", "other") modparam("snmpstats", "snmpgetPath", "/usr/bin/") modparam("snmpstats", "MsgQueueMinorThreshold", 1) modparam("snmpstats", "MsgQueueMajorThreshold", 1) modparam("snmpstats", "dlg_minor_threshold", 1) modparam("snmpstats", "dlg_major_threshold", 1) modparam("snmpstats", "snmpCommunity", "kamailio") I have set the *_minor_threshold values to bear minimum.

Function sdp_get gets extra blank line (when MIME is used)
by James Browne 05 Nov '24

The sdp_get() function from sdpops returns an extra blank line sometimes, which looks like a bug to me. When I have an SDP that's in MIME, there's an extra newline at the end of the extracted SDP. Here's a sample config. I use 5.8.1 for testing. #################### #!KAMAILIO listen=udp:203.0.113.57:5060 debug=1 loadmodule "sdpops" loadmodule "pv" loadmodule "xlog" request_route{exit;} reply_route { sdp_get("$avp(sdp)"); xlog("L_NOTICE", "[$ci] The SDP is [$avp(sdp)].\n"); } #################### Here are two sample SIP-message bodies. #################### v=0 o=PCD 1730 1730 IN IP4 198.18.114.148 s=PCD c=IN IP4 198.18.114.148 t=0 0 m=audio 29426 RTP/AVP 0 a=rtpmap:0 PCMU/8000 #################### #################### --e61e7a6a-16a2-46c0-adbb-a41ba86d32a2 Content-Type: application/sdp Content-Length: 130 v=0 o=PCD 1730 1730 IN IP4 198.18.114.148 s=PCD c=IN IP4 198.18.114.148 t=0 0 m=audio 29426 RTP/AVP 0 a=rtpmap:0 PCMU/8000 --e61e7a6a-16a2-46c0-adbb-a41ba86d32a2-- #################### When the first body is received, the xlog correctly ends with this. m=audio 29426 RTP/AVP 0 a=rtpmap:0 PCMU/8000 ] with length 130 When the second body is received, the xlog incorrectly ends with this, which has an extra newline in it. m=audio 29426 RTP/AVP 0 a=rtpmap:0 PCMU/8000 ] with length 132 According to RFC2046, "The CRLF preceding the boundary delimiter line is conceptually attached to the boundary", but it looks like kamailio has a bug that incorrectly processes this.

Simultaneous INVITE responses from multiple branches
by Anton Yabchinskiy 04 Nov '24

04 Nov '24

Hello, In our system we've encountered the following situation. There's a Kamailio proxy and a few REGISTER'ed devices behind the proxy. When there's an INVITE to these multiple devices, two of them simultaneously answer the call. Kamailio proxy accepts the first 200 OK from one of the devices and tries to CANCEL all other branches. But the second 200 OK device have already responded OK and doesn't acknowledge the CANCEL. So, there's now one established dialog with media, and another "established" one neither having media nor being correctly terminated. Looks like the similar scenario is described in section 3.1.2 of RFC 5407 (Example Call Flows of Race Conditions in the Session Initiation Protocol (SIP)). Is it possible to mitigate such scenarios in a Kamailio proxy? E.g., is it possible to send an additional BYE to these CANCEL'led branches? In current configuration, Kamailio proxy retrieves contacts with registrar:lookup() and does parallel forking with tm:t_relay().

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.

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?

$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*

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

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!

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

Re: About error running PCSCF

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. About VOLTE, I don't know how to try or maybe I must change to the other APN (ims). [image: image.png] Please let me know, I only have the problem with VOLTE service and how to try 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
