Hello! Kamailio 5.7.6 Debian 10.12 Here is my authentication route: ``` route[AUTH] { if (is_method("REGISTER") || from_uri==myself) { if (!auth_check("$fd", "subscriber", "0")) { auth_challenge("$fd", "2"); # flag not 0 exit; } # user authenticated - remove auth header if(!is_method("REGISTER|PUBLISH")) consume_credentials(); } ... } ``` start eyebeam Version 1.5.14.4 ``` eyebeam --->REGISTER ----> kamailio <--401 (WWW-Authenticate: Digest realm="192.168.3.10", nonce=..., qop="auth-int") --->REGISTER (Authorization: Digest username="08001",realm="192.168.3.10",nonce=...,uri=...,response=...,cnonce=...,nc=00000001,qop=auth-int,algorithm=MD5) <--401 (auth_challenge() return -2 ) ``` OpenSIPS 3.4.12 register to kamailio, got the same result as eyebeam Any suggestions? Thanks!

Kamailio TLS Listener Not Binding to Port (5061 or 10061)
by steven.muchwe 25 Apr '25

25 Apr '25

Hello Kamailio Community, I’ve been troubleshooting an issue with Kamailio where the TLS listener fails to bind to any specified ports (5061, 10061, etc.), despite valid configurations and certificates. Here’s a summary of my setup and steps taken: 1. *Environment Details*: - Kamailio version: 5.7.4 - OpenSSL version: 3.0.13 - Operating System: Ubuntu (Noble Release) - TLS module (tls.so) is installed and loaded. 2. *Issue Details*: - Configurations validate successfully (config file ok). - OpenSSL works perfectly when testing certificates and keys with s_server, binding to ports (5061 and others). - Kamailio fails to bind TLS listeners (ss -tulnp shows no activity on the specified ports). 3. *Steps Already Taken*: - Simplified TLS configuration (minimal_tls.cfg) with: plaintext listen=tls:10.14.202.39:5061 loadmodule "tls.so" modparam("tls", "certificate", "/home/localtech/vicissl/868a963bc33d5eae.crt") modparam("tls", "private_key", "/home/localtech/vicissl/private.key") - Tested multiple ports (5061, 10061, 15061). - Checked firewall settings (iptables) and confirmed no restrictions. - Rebuilt Kamailio from source and ensured TLS modules are linked to OpenSSL. - Ran Kamailio with maximum debugging (-ddd) to examine logs—no binding-related errors appeared. 4. *Log Excerpts*: (Attach relevant logs showing TLS initialization or lack of binding activity.) 5. *Question*: What additional steps or configurations should I explore to resolve this issue? Could this be a compatibility problem between Kamailio 5.7.4 and OpenSSL 3.0.13? Any guidance or insights would be greatly appreciated! Best regards, Steven Muchwe Njoroge

Re: SIP Call Drops After 0.32 Seconds – Asterisk on Kubernetes with Kamailio + RTPengine

I will let the more experienced Kamailio folks comment on the technical/Kamailio/RTP modifications that you need to make. The SIP standard requires an ACK to a 200 OK to be sent within that 32 second window. If an ACK is not received, the session is torn down. You would need to do a packet capture to review the Contact header in the SIP and the c: in the SDP. I'm just getting bedded in with SIP, reading Alan B Johnston's "SIP: Understanding the Session Initiation Protocol". Excellent introduction to understanding SIP.

rtpengine module does not detect new nodes in table
by David Cunningham 24 Apr '25

24 Apr '25

Hello, We are using Kamailio 5.8.2 with the rtpengine module on Ubuntu 22.04. The "rtpengine" table is used to define nodes, with a configuration like this: modparam( "rtpengine", "db_url", DB_URL ) modparam( "rtpengine", "table_name", "rtpengine" ) modparam( "rtpengine", "setid_default", 1 ) It works fine if Kamailio is restarted after entries in the "rtpengine" table are inserted or deleted, but new entries in the table aren't detected automatically. Is there a way to configure Kamailio to detect them? Thank you, -- David Cunningham, Voisonics Limited http://voisonics.com/ USA: +1 213 221 1092 New Zealand: +64 (0)28 2558 3782

Again, not super skilled yet with Kamailio/RTPEngine, but my first instinct is: "why you are advertising myproxyname.domain.net which is possibly a public IP". Your entire setup is in your LAN so you don't need to advertise any public IP.

RTPengine media starts for intiating caller only
by smh2017＠zoho.com 23 Apr '25

23 Apr '25

Hello, I have a problem with my basic Kamailio setup using RTPengine. I'm testing initially with two client UAs in the same LAN as the SIP server behind the firewall. The initiating UA starts the media proxy as soon as the receiving UA accepts the call, indicated by the call timer starting. But after accepting the call the receiving UA's timer doesn't start and after 10-15 secs hangs up with a NO ACK error message. I am using the kamailio default config file that comes with the Debian package and have made minimal changes recommended by various How-Tos for using Kamailio behind a firewall. Because the clients can successfully register over TLS, I'm assuming the problem is in the rtpengine configuration. The two rtp listen parameters I've tried are: interface = internal/192.168.1.100;external/192.168.1.100!myproxyname.domain.net --or-- interface = internal/192.168.1.100;external/myproxyname.domain.net listen-ng = localhost:2223 I'm not sure why some example rtpengine configs list both the private and public addresses as external. Any suggestions where to start troubleshooting? Thanks, Steve

SIP Call Drops After 0.32 Seconds – Asterisk on Kubernetes with Kamailio + RTPengine
by Fernando Lopes 23 Apr '25

23 Apr '25

Hello everyone, I'm running into an issue with SIP calls in my current setup and would really appreciate some help. Setup: I have a machine named sip00 (IP: 192.168.1.75) running Kamailio + RTPengine. Kamailio is dispatching calls to sip:192.168.1.190:32210;transport=tcp. This IP points to another machine running Asterisk inside a Kubernetes cluster. RTPengine is configured with an RTP port range of 10000–20000, and my router is set to allow that same range. Asterisk Kubernetes Service Configuration: yaml Copy Edit spec: ports: - name: tcp-port protocol: TCP port: 5060 targetPort: 5060 nodePort: 32210 - name: udp-port protocol: UDP port: 5060 targetPort: 5060 nodePort: 32210 Problem: When I initiate a SIP call, the router forwards traffic to Kamailio + RTPengine, which then sends it to the Asterisk server on 192.168.1.190. Everything seems fine initially, but at exactly 0.32 seconds into the call, Asterisk sends a BYE and no longer responds with 200 OK to the SIP dialog — even though I'm still receiving and sending audio. Then, at around 01:04, I get a 408 Request Timeout. Questions: Do I need to explicitly expose the RTP port range (10000–20000) in the Asterisk Kubernetes service as well? Why is Asterisk sending a BYE so early if audio is still flowing? Could it be a signaling timeout or an issue with SIP dialog tracking? Any help or pointers would be greatly appreciated! Thanks in advance!

404 sent from Kamailio NOT from the script
by Richard Robson 23 Apr '25

23 Apr '25

I have a problem where a call comes in and causing a 404 Not Found to be replied. the script does not have a 404 reply set in it anywhere unfortunately I cannot get the script to produce logs, hence my other post. But its making it tricky to find the source of the 404. following the script it should not be producing a 404, but doing a relay. I suspect there is something wrong with the tm or its not getting a result it needs. It looks like the transaction module is triggering thge 404 somehow and Its showing up in debug below. Does anyone have any ideas why i'm getting a 404? version 5.6.6 Regards, Richard Apr 22 14:50:51 kamai01 kamailio[28700]: DEBUG: {1 1 INVITE afc0c04-9d8bc3d-1bfb9be-7f02f033b5f0-2406050a-13d8-7225} tm [t_lookup.c:1100]: t_check_msg(): msg (0x7faf977b64b0) id=4/28700 global id=3/28700 T start=0xffffffffffffffff Apr 22 14:50:51 kamai01 kamailio[28700]: DEBUG: {1 1 INVITE afc0c04-9d8bc3d-1bfb9be-7f02f033b5f0-2406050a-13d8-7225} tm [t_lookup.c:503]: t_lookup_request(): start searching: hash=60776, isACK=0 Apr 22 14:50:51 kamai01 kamailio[28700]: DEBUG: {1 1 INVITE afc0c04-9d8bc3d-1bfb9be-7f02f033b5f0-2406050a-13d8-7225} tm [t_lookup.c:463]: matching_3261(): RFC3261 transaction matching failed - via branch [z9hG4bK-2e6a90ab-1bfb9be-d4ed8e5d-7f0300025430] Apr 22 14:50:51 kamai01 kamailio[28700]: DEBUG: {1 1 INVITE afc0c04-9d8bc3d-1bfb9be-7f02f033b5f0-2406050a-13d8-7225} tm [t_lookup.c:703]: t_lookup_request(): no transaction found Apr 22 14:50:51 kamai01 kamailio[28700]: DEBUG: {1 1 INVITE afc0c04-9d8bc3d-1bfb9be-7f02f033b5f0-2406050a-13d8-7225} tm [t_lookup.c:1172]: t_check_msg(): msg (0x7faf977b64b0) id=4/28700 global id=4/28700 T end=(nil) Apr 22 14:50:51 kamai01 kamailio[28700]: DEBUG: {1 1 INVITE afc0c04-9d8bc3d-1bfb9be-7f02f033b5f0-2406050a-13d8-7225} tm [t_lookup.c:1394]: t_newtran(): msg (0x7faf977b64b0) id=4/28700 global id=4/28700 T start=(nil) Apr 22 14:50:51 kamai01 kamailio[28700]: DEBUG: {1 1 INVITE afc0c04-9d8bc3d-1bfb9be-7f02f033b5f0-2406050a-13d8-7225} tm [t_lookup.c:503]: t_lookup_request(): start searching: hash=60776, isACK=0 Apr 22 14:50:51 kamai01 kamailio[28700]: DEBUG: {1 1 INVITE afc0c04-9d8bc3d-1bfb9be-7f02f033b5f0-2406050a-13d8-7225} tm [t_lookup.c:463]: matching_3261(): RFC3261 transaction matching failed - via branch [z9hG4bK-2e6a90ab-1bfb9be-d4ed8e5d-7f0300025430] Apr 22 14:50:51 kamai01 kamailio[28700]: DEBUG: {1 1 INVITE afc0c04-9d8bc3d-1bfb9be-7f02f033b5f0-2406050a-13d8-7225} tm [t_lookup.c:703]: t_lookup_request(): no transaction found Apr 22 14:50:51 kamai01 kamailio[28700]: DEBUG: {1 1 INVITE afc0c04-9d8bc3d-1bfb9be-7f02f033b5f0-2406050a-13d8-7225} <core> [core/mem/q_malloc.c:385]: qm_malloc(): qm_malloc(0x7faf9301f000, 8336) called from tm: h_table.c: build_cell(336) Apr 22 14:50:51 kamai01 kamailio[28700]: DEBUG: {1 1 INVITE afc0c04-9d8bc3d-1bfb9be-7f02f033b5f0-2406050a-13d8-7225} tm [t_hooks.c:342]: run_reqin_callbacks_internal(): trans=0x7faf932f42c0, callback type 1, id 0 entered Apr 22 14:50:51 kamai01 kamailio[28700]: DEBUG: {1 1 INVITE afc0c04-9d8bc3d-1bfb9be-7f02f033b5f0-2406050a-13d8-7225} <core> [core/mem/q_malloc.c:385]: qm_malloc(): qm_malloc(0x7faf9301f000, 40) called from tm: t_hooks.c: insert_tmcb(134) Apr 22 14:50:51 kamai01 kamailio[28700]: DEBUG: {1 1 INVITE afc0c04-9d8bc3d-1bfb9be-7f02f033b5f0-2406050a-13d8-7225} tm [t_lookup.c:1100]: t_check_msg(): msg (0x7faf977b64b0) id=4/28700 global id=4/28700 T start=0x7faf932f42c0 Apr 22 14:50:51 kamai01 kamailio[28700]: DEBUG: {1 1 INVITE afc0c04-9d8bc3d-1bfb9be-7f02f033b5f0-2406050a-13d8-7225} tm [t_lookup.c:1176]: t_check_msg(): T (0x7faf932f42c0) already found for msg (0x7faf977b64b0)!

Behaviour of suspended transactions
by Alex Balashov 18 Apr '25

18 Apr '25

Hello! Two questions about suspended transactions: 1) What is the lifetime of a suspended INVITE transaction? Can I change it? 2) While a transaction is suspended, its event hooks (e.g. onreply_route, failure_route) do not run, of course, even if replies that match the transaction are received. Is there a way to intercept these replies externally and resume the transaction upon the receipt of the reply, and prior to the processing of the reply? For example, can the replies be captured in a stateless route, and mapped Call-ID => index/label to t_continue() the transaction, then have the transaction state machine process that very same reply too? t_is_retr_async_reply() seems to hint at this intention, but its scope is more narrow, if I understood the documentation correctly: it seems to deal with retransmissions only. The code path I'm interested in is more akin to a t_is_reply_to_async() function. As you might guess, the driver for this inquiry is a mobile workflow where, in the vast majority of cases, one is contacting a stale registration and should just suspend the transaction, but where occasionally, in a small minority of cases, the endpoint does respond on the existing contact. The standard tsilo workflow of trickling parallel branches into a pending transaction doesn't work here because of the behaviour of Apple's CallKit; we have to try the existing contact _before_ we send a push notification. -- Alex -- Alex Balashov Principal Consultant Evariste Systems LLC Web: https://evaristesys.com Tel: +1-706-510-6800

*Dear Sir,* I have opened an issue on GitHub: *"IPv6 bind wrong IP. #4199 <https://github.com/kamailio/kamailio/issues/4199>"*. *System Details:* - *Kamailio (5.8.x)* – SIP Proxy - *FreeSWITCH* – Media Server - *OS* – Debian 12 - *Gateway* – aaaa:bbb:cccc:20::1 - *IPv6 Address* – aaaa:bbb:cccc:20::41e ------------------------------ *kamailio.cfg:* #!define ADDR_IPV4 xxx.xxx.xxx.xxx #!define ADDR_IPV6 [aaaa:bbb:cccc:20::41e] listen=ADDR_IPV4 listen=ADDR_IPV6 ------------------------------ *netstat Output:* tcp6 0 0 aaaa:bbb:cccc:20:::5060 :::* LISTEN 1691274/kamailio tcp6 0 0 aaaa:bbb:cccc:20:::5061 :::* LISTEN 1691274/kamailio udp6 0 0 aaaa:bbb:cccc:20:::5060 :::* 1691222/kamailio As shown, although I explicitly set the listen IP to aaaa:bbb:cccc:20::41e, Kamailio strips the last part of the address and binds to aaaa:bbb:cccc:20:: I also upgraded to *version 6.0* with default cfg and set auto_bind_ipv6=1 or changed ipv6 address, but the issue still persists. ------------------------------ *IPv6 Interface Configuration:* auto eth1 iface eth1 inet6 static address aaaa:bbb:cccc:20::41e netmask 64 gateway aaaa:bbb:cccc:20::1 I can successfully ping in and out using this IPv6 address. ------------------------------ Do I need to configure anything else in Kamailio or the system to ensure it binds to the full IPv6 address aaaa:bbb:cccc:20::41e as expected? Currently I can register with ipv4, but ipv6 does not. Thank you for your assistance.

Handling NAT Keepalive in IMS PCSCF Configuration: Bypassing NATHelper Module
by f.soltanzade72＠gmail.com 16 Apr '25

16 Apr '25

Hi All, In the default Kamailio configuration, keepalive handling for NAT is typically managed through the NATHelper module. However, in the IMS PCSCF configuration, the NATPING route is used to send SIP OPTIONS messages for keepalive, which bypasses the NATHelper module. This approach makes it impossible to send raw UDP packets for keepalive handling. Can any one help me configuring that? Thank you.

How to place a delay between cancelling branch and retrying next one on timer expiry?
by Alex A 15 Apr '25

15 Apr '25

Hi All, I have an interesting use-case where I need to place a delay between cancelling branch and retrying next one. *Background: * Running Kamailio 5.6.x Kamailio routes requests via a freeswitch B2BUA server on select call flows (where B2BUA functionality is required). Call flow examples: PSTN --> Kamailio --> Freeswitch --> appserver1 PSTN --> Kamailio --> Freeswitch --> appserver2 On attempt failures, a branch retry is required from appserver1 to appserver2; however freeswitch B2BUA remains the same Since Freeswitch does not quite follow the RFC 3261 timer K specifications (should be 0 seconds for reliable transports, but FS keeps transactions for T4 (set to 2 seconds)); I have implemented an artificial delay in failure route before retrying (as per recommendation described here: https://freeswitch-users.freeswitch.narkive.com/TsSye66D/482-request-merged… ) *Script config: * onreply_route[MANAGE_REPLY] { xlog("L_INFO", "reply $T_reply_code received"); if (t_check_status( "1[1-9][0-9]")) { t_reset_fr(); } else { t_set_fr(120000); } } route(NATDETECT); #!ifdef WITH_RTPENGINE route(RTPMANAGE); #!endif } route[RELAY] { if (is_method("INVITE|BYE|SUBSCRIBE|UPDATE")) { if(!t_is_set("branch_route")) t_on_branch("MANAGE_BRANCH"); } if (is_method("INVITE|SUBSCRIBE|UPDATE")) { if(!t_is_set("onreply_route")) t_on_reply("MANAGE_REPLY"); } if(is_method("INVITE|BYE|UPDATE|CANCEL|ACK")) { setflag(FLT_DLGINFO); } if (!t_relay()) { sl_reply_error(); } exit; } route[TOCARRIER] { process bunch of things, attach custom headers, generate request URI t_on_failure("MANAGE_FAILURE_CARRIER"); route(RELAY); } failure_route[MANAGE_FAILURE_CARRIER] { xlog("L_INFO", "reply $T_reply_code received"); if ($avp(inbound_attempt)<=1){ if ($dlg_var(b2bua)=="true"){ usleep(1900000); } route("TOCARRIER"); } *Call Flows: * The above fix works well when an explicit error reply is received back. *error reply SIP exchange: * SBC --> INVITE(branch0) ---> Freeswitch SBC <-- 503 <-- Freeswitch failure_route executed (sleep runs here) SBC --> INVITE(branch1) ---> Freeswitch call continues as expected. however does not work when NO reply is received at all and the timer expires. *Current timer expiry SIP exchange: * SBC --> INVITE(branch0) ---> Freeswitch SBC <-- 100/180 <-- Freeswitch SBC (timer expires) failure_route executed (sleep runs here) SBC --> INVITE(branch1) ---> Freeswitch SBC <-- 482 Merged <-- Freeswitch SBC --> CANCEL(branch0) ---> Freeswitch I am looking to CANCEL branch0 before the sleep delay runs Based on source code, t_cancel_branches("this") can only be executed in reply_route; however the chellenge is that reply_route never sees the "faked 408" on timer expiry(although the failure route does see $T_reply_code 408). Any suggestions on how to handle this would be greatly appreciated. TIA

RTPEngine pool selection for in-dialog requests
by Ben Kaufman 15 Apr '25

15 Apr '25

I'm looking for information on the correct way to handle calls to RTPEngine when processing in-dialog requests. I currently have several setid's configured for varying usages. During processing of an initial INVITE, a determination is made as to if the call will require the use of RTPEngine, and if so, which of the sets should be used. The following is done in code: * setid is assigned to AVP $avp(rtpengine_pool_num) * set_rtpengine_set("$avp(rtpengine_pool_num)") is called, * rtpengine_offer is then called. * Additionally, a record-route parameter of proxy_media=yes is added. * The flag PROXY_MEDIA is set In the reply route, the PROXY_MEDIA flag is checked, and if set, set_rtpengine_set("$avp(rtpengine_pool_num)") is called, followed by rtpengine_answer. When handling an in-dialog message my code didn't have anything to evaluate for the setid. rtpengine_offer was just called. Looking at the debug from the rtpengine module, I can see that the record is found in the hashtable, however the node indicated in that result is not necessarily used - rtpengine will select an entry from the default setid instead. From the rtpengine module logs, IP addresses redacted: 2(9) DEBUG: {time=1744651756.968228} rtpengine [rtpengine_funcs.c:139]: check_content_type(): type <application/sdp> found valid 2(9) DEBUG: {time=1744651756.968228} rtpengine [rtpengine.c:2249]: build_rtpp_socks(): same rtpengines list version: 1 (1744651613) 2(9) DEBUG: {time=1744651756.968228} rtpengine [rtpengine.c:3818]: select_rtpp_node_old(): rtpengine hash table lookup find node=udp:A.B.C.D:1234 for calllen=36 callid=ac66f56b-93f8-123e-1b99-0242ac120002 viabranch= 2(9) DEBUG: {time=1744651756.968228} rtpengine [rtpengine.c:3702]: select_rtpp_node_new(): sum is = 210 2(9) DEBUG: {time=1744651756.968228} rtpengine [rtpengine.c:3198]: rtpp_function_call(): proxy reply: d3:sdp288:v=0 o=FreeSWITCH 1744611570 1744611571 IN IP4 W.X.Y.Z s=FreeSWITCH c=IN IP4 W.X.Y.Z My question is really: **SHOULD** rtpengine_offer (and rtpengine_manage, etc) use the node that it finds in the hash table lookup automatically, or should I have to explicitly set the setid? For now I've solved the problem by adding the setid to the record-route headers so I can easily retrieve it in dialog, but it seems that if the module finds a record for a node that there should be some way to rely on that explicitly.

Nat Problems Kamailio
by Fernando Lopes 14 Apr '25

14 Apr '25

Hello Everyone, I'm having some trouble getting my SIP setup to work properly. 📞 My Call Flow: SIP Client initiates a call The call reaches my router, which forwards it to Kamailio + RTPengine running on 192.168.1.75:5060, which then forwards it to A Kubernetes machine at 192.168.1.190:32210, where Asterisk is running 🔧 Network Setup: Router has the following ports forwarded: UDP 5060 UDP 10000–20000 (for RTP) STUN is enabled on the SIP client ✅ What Works: When I’m connected through a VPN (i.e., inside the local network), everything works fine — both incoming and outgoing audio. ❌ The Problem: When calling from outside the network, signaling works and the call connects, but I can’t receive or send any audio. Here is a little of my config of kamailio modparam("rtpengine", "rtpengine_sock", "udp:127.0.0.1:2223") modparam("rtpengine", "setid_avp", "$avp(setid)") listen=udp:192.168.1.75:5060 advertise

TCP timeout
by Pyry Aaltonen 11 Apr '25

11 Apr '25

Hello, I´ve googled around about tcp timeout in kamailio tcp connections when the tcp connection is broken. Found this old question and to me it feels like I’m having that same situation as original question https://www.mail-archive.com/sr-users@lists.kamailio.org/msg15020.html Also found this https://kamailio.org/mailman3/hyperkitty/list/sr-dev@lists.kamailio.org/thr… and it seems to be the same description pretty much that I´m seeing. When the tcp connection (or tls) is interrupted in the network it takes around 15min for kamailio to reset the outgoing tcp connection. I see in the logs that when restarting kamailio process it logs 2025-03-27 12:25:18.697 { "level": "INFO", "module": "core", "file": "core/tcp_main.c", "line": 3282, "function": "tcp_init", "logprefix": "", "message": "Set TCP_USER_TIMEOUT=10000 ms" } So I think the fix from this https://github.com/kamailio/kamailio/commit/d893f3af1444c8c4c5db6cd53fb5777… is applied. This is tested with 5.8.5 and I have tested this by setting up with dispatcher tcp connection to external host Then with iptables drop traffic to that host, waiting kamailio to notice that destination is down, removing the iptables input and it takes around 15min to recover. (also restarting the kamailio helps and resolves the connection) And this is what kamailio prints during the test: Apr 4 08:29:15 kamailio[156947]: { "level": "ERROR", "module": "xlog", "file": "xlog.c", "line": 278, "function": "", "logprefix": "", "message": "Destination down: OPTIONS sip:ext-host;transport=tcp (<null>)" } Apr 4 08:44:43 kamailio[156957]: { "level": "ERROR", "module": "core", "file": "core/tcp_read.c", "line": 267, "function": "tcp_read_data", "logprefix": "", "message": "error reading: Connection timed out (110) ([]:5060 -> []:47492)" } Apr 4 08:44:43 kamailio[156957]: { "level": "ERROR", "module": "core", "file": "core/tcp_read.c", "line": 1524, "function": "tcp_read_req", "logprefix": "", "message": "error reading - c: 0x7f8625dea9b0 r: 0x7f8625deaad8 (-1)" } Apr 4 08:45:05 kamailio[156957]: { "level": "ERROR", "module": "xlog", "file": "xlog.c", "line": 278, "function": "", "logprefix": "Source:[ext-host]:5060, Call-id:4d0e1ccd315c817f-156947@int-host, CSeq:10", "message": "Destination up: OPTIONS sip:ext.host;transport=tcp (<null>)" } Any advice how to lower the timeout to be quicker in such event? -Pyry

STUN Server vs. NAT Configuration with Kamailio + RTPengine Setup
by Fernando Lopes 11 Apr '25

11 Apr '25

Previous Thread: https://kamailio.org/mailman3/hyperkitty/list/sr-users@lists.kamailio.org/t… Hello everyone, Should I use a STUN server, or can I just configure NAT properly? Here’s my current setup: arduino Copy Edit Router (NAT device) ↓ Kamailio + RTPengine machine ↓ Virtual machine running Kubernetes ↓ Asterisk container Kamailio and RTPengine are sitting behind the NAT (the router), and they handle SIP and media. Do I need a STUN server in this case, or can I manage everything with NAT configuration alone? And what is the better approach? Any insights or best practices would be appreciated! Thank you.

IPv6 bind wrong IP. #4199

Hi guys, I opened issue on github: https://github.com/kamailio/kamailio/issues/4199 - Description: Kamailio (5.8.x): SIP proxy FreeSWITCH: Media - OS: Debian 12 gateway: aaaa:bbb:cccc:20::1 ipv6: aaaa:bbb:cccc:20::41e - kamailio.cfg: #!define ADDR_IPV4 xxx.xxx.xxx.xxx #!define ADDR_IPV6 [aaaa:bbb:cccc:20::41e] listen=ADDR_IPV4 listen=ADDR_IPV6 - I execute netstat -nlutp: tcp6 0 0 aaaa:bbb:cccc:20:::5060 :::* LISTEN 1691274/kamailio tcp6 0 0 aaaa:bbb:cccc:20:::5061 :::* LISTEN 1691274/kamailio udp6 0 0 aaaa:bbb:cccc:20:::5060 :::* 1691222/kamailio Why I set listen ip is aaaa:bbb:cccc:20::41e but kamailio stripped the last part of the address aaaa:bbb:cccc:20:: I have tried many ways but it does not work.Is there any additional configuration required regarding the Debian network interface? - Here is interfaces(of course i can ping from/to ipv6 address): # Additional interfaces, just in case we're using # multiple networks allow-hotplug eth1 iface eth1 inet6 static address aaaa:bbb:cccc:20::41e netmask 64 gateway aaaa:bbb:cccc:20::1 autoconf 0 Thank you.

Load multiple geoip2 databases (City + ASN)
by Joel Serrano 10 Apr '25

10 Apr '25

Hi guys, Is there a way to have multiple geoip2 databases loaded into Kamailio and then point the geoip2_match to them? If I understand correctly the docs I can only load one: https://www.kamailio.org/docs/modules/6.0.x/modules/geoip2.html#geoip2.p.pa… Is my assumption correct? Thanks, Joel.

Kamailio + RTP Engine question
by fernandolopes20003＠gmail.com 08 Apr '25

08 Apr '25

Hi everyone, I'm experiencing some issues with Kamailio and RTP Engine. Here's the setup: A user initiates a call, and the traffic goes through a router. The router forwards the traffic to a machine at 192.168.1.75, which runs Kamailio and RTP Engine. Kamailio uses a dispatcher to forward calls to 192.168.1.190, a Kubernetes node running an Asterisk container. The problem: When I'm inside the network, everything works fine — I can send and receive audio. But when I'm outside the network, the call connects, but there's no audio in either direction (no send or receive). Some Configs: Kamailio.conf: modparam("rtpengine", "rtpengine_sock", "udp:0.0.0.0:2223") listen=udp:192.168.1.75:5060 listen=tcp:192.168.1.75:5060 listen=udp:127.0.0.1:5060 # ----- dispatcher params ----- modparam("dispatcher", "list_file", "/etc/kamailio/dispatcher.list") modparam("dispatcher", "flags", 2) modparam("dispatcher", "xavp_dst", "_dsdst_") modparam("dispatcher", "xavp_ctx", "_dsctx_") modparam("dispatcher", "ds_ping_from", "sip:proxy@kamailio.org") modparam("dispatcher", "ds_ping_interval", 60) modparam("dispatcher", "ds_probing_mode", 1) modparam("dispatcher", "ds_timer_mode", 1) rtpengine.conf: interface = 192.168.1.75 listen-udp = 0.0.0.0:2223 port-min = 10000 port-max = 20000 Firewall: To Action From -- ------ ---- 22 ALLOW Anywhere 12222/udp ALLOW Anywhere 5060/udp ALLOW Anywhere 10000:20000/udp ALLOW Anywhere 22 (v6) ALLOW Anywhere (v6) 12222/udp (v6) ALLOW Anywhere (v6) 5060/udp (v6) ALLOW Anywhere (v6) 10000:20000/udp (v6) ALLOW Anywhere (v6) Also router has all this ports open Thank you.

Info: Donating To Kamailio Project
by Daniel-Constantin Mierla 07 Apr '25

07 Apr '25

Hello! Over the years, there have been discussions about what options could be made available to donate to Kamailio project in order to support its required infrastructure, administrative or development of complex components. Creating a foundation or using a crowdfunding platform have been explored, trying to take in consideration the needed man power and overhead, the transparency and accountability. To move forward on this matter, the Kamailio management team has decided to use Open Collective, with the fiscal host Open Collective Europe, as the platform for accepting and managing donations, more details, including the link where donations can be made, are published at: - https://www.kamailio.org/w/donations/ The donations should target either the support of project administration or the development of new feature, therefore before donating it is recommend to email to <management [at] lists.kamailio.org> providing some details about the scope of your donation. We also plan to discuss about it at the next Kamailio World Conference: May 12-13, 2025, organized again in Berlin, Germany, where many developers and members of the management board and our community get together, being a good opportunity to clarify and decide how to use the donations. More details about the event at: - https://www.kamailioworld.com Thanks for flying Kamailio!

New direction for Kamailio under Russian military administration
by Alex Balashov 01 Apr '25

01 Apr '25

For immediate release: BERLIN, Germany (1 April 2025)--The newly appointed executive and political head of the Russian Military Administration of Kamailio (R-MAK), General Alexander Balashov, has issued a proclamation: diversity, equity and inclusion (DEI) initiatives in the Kamailio will be fiscally de-emphasised, 'woke' modules will be removed in future releases, and realist relations with other open-source projects and commercial stakeholders will be sought, based henceforth on the 'pragmatics' of relative strength and strategic advantage, calculated from the extrapolated monetary value of Github commits. To note, the Kamailio project came into the remit of Balashov and R-MAK following the dissolution of the post-war transatlantic alliance system and the capitulation of NATO in the first quarter of 2025. These events were followed by direct negotiations between US Vice President J.D. Vance and the Government of the Russian Federation on the future course of Kamailio and SIP real-time communications, in which it was quickly concluded by both parties that Kamailio fell into the Russian sphere of influence. In an interview with Balashov, our bright and patriotic staff here at 'Krasnaya Zvezda' pressed him to further articulate and clarify the 'new thinking', as the new R-MAK initiatives have been informally dubbed around the offices of Kamailio. What follows is a selection of his remarks. Our first question to Balashov was on the tip of many journalists' tongues: what are the most woke modules in Kamailio? 'How should I know? They are everywhere, lots of people sayink it', Balashov answered, gesturing airily at the ceiling. 'Our specialists lookink on case-by-the-case basis. But sometimes is obvious, for example the JavaScript modules, like app_jsdt. This is clearly to subsidise a certain kind of morally deficient person.' What kind of person? we inquired, to be met with a characteristic frosty reply: 'You know the kind.' Our next question concerned some confusion about where, exactly, DEI initiatives are found in Kamailio today: 'From what I know this? Like swamp, this source code. How to say it, "drainink?" Yes, yes, I want to do that with swamp. Zero-based budget approach. Do you know it?' Asked to clarify, Balashov added: 'It's new idea from good friend Elon and the very efficient Dozh. Is good. We remove all module, then we look: what is broken? For example from technical viewpoint or political? What is broken? Maybe nothing.' One could be forgiven for wondering what 'broken' means in this context. We asked Balashov: does it mean CI tests no longer passing? 'No, no, no, automated tests are vegan soy-boy agenda. If you automatically test, when will you ever write correct code? I will not, I know automatic test will catch. Lazy approach. This idea, "test test test", for small minds. Do you know history of CI/CD? Propaganda is that Americans came up with it, but did not. Is invented by people from countries of later-times accession to EU, they are be-ne-fi-ci-aries of Bruxelle redistributionink policy, social cohesions grants and regional economic development equalisation initiatives, like something from socialist bloc countries or maybe Mezzogiorno, without otherwise much work prospects, until suddenly: unemployed guy with idea! "I am now Directeur of Le Cloud DevOps!" What is DevOps? It is from nothing, but suddenly hearing this in cultured places, theatres, palaces, galleries. Where it comes from? Why nobody asks? This is the old political correctness, and now we must release this suffocation with fresh and original thinking.' When our team asked for a concrete example of R-MAK's zero-based module trimming process, Balashov did not hesitate to focus on a well-known preoccupation: 'The most obvious example of very much not-needed module is TM. I Snapchat good friend Elon and I say him, "is it needed?" He says "no". But maybe I don't trust, GRU say he is always with marijuana, likewise ketamine. I make FaceTime with Milei: "¿Vos querés TM?" He says, "¡Que se vaya a la mierda y también los izquierdistas!" I phone Donald, "what do you think about this TM?" He says, "I signed a tremendous executive order to ban it this morning". I bother Orban in the middle of the night: "I am awake, asking myself, asking my wife: who needs TM?", and he answers: "no man who is civilisationally compatible with European values". Now I go to public sector union subreddits and askink same, and there is much noise and raging and I lose the karma, downvote to negative 26. I WhatsApp the leftists and they squeal. I Microsoft Teams to Bill Clinton and he says "TM is a key component of the international Kamailio order, used in 95% of configurations worldwide". Great! The answer is more clear than Lake Baikal: TM, goodbye, and I never knew you!' What else is marked for deletion?, wondered a contributing staff writer. On this point, Balashov was coy, declining to reveal the full working draft of slated cuts. However, he was not wholly unwilling to preview the direction of travel for the fate of Kamailio's 250+ modules. 'The STIR-SHAKING stuff of course gone. Now you can saying again "master-slave replication", as nature wills, without guilt, for which to be forced to this fake apologetics, "primary-secondary replication". Cannot anymore "blacklist"? What this emotionally constipated style? And likewise freedom means free to make telemarket without performative rituals of atonement for the sins.' Balashov went on to cite President Donald Trump, who had remarked: 'Robocall mitigations are money grab by failing FCC and their Trump-hating Democrat croneys. People are saying they are issuing eighth report and order, they are believing the fake liberal news. It's going to stop, and it's going to stop right now.' Balashov also intimated that he did not hold dearly in his heart the 'carrierroute' module, which he linked, in the memorable words of Fox News' Laura Ingraham, to 'the chattering vaccinated classes': 'What gigahertz your immunology system vibrates at? Mine for example clean, not 5G.' Next, we posed a question from a reader: are these changes to Kamailio simply drafting in the slipstream of global realignment, anti-free trade momentum, backlash against progressive cultural totems, as well as, in the United States specifically, the inward turn, the withdrawal from internationalism, and the return to 19th century great power realism in international relations, under the new administration of Donald Trump? 'Da, sure, of course gettink along with fraternal peoples very important, but also some important difference from Anglo-Americans. In R-MAK we are constructing "reaction with European characteristics" and the goals are too broader, coalitions bigger.' For help in understanding where R-MAK's reimagined Kamailio stakes its claim in the shifting international order and in the contested claims of popular mandates and political legitimacy, we consulted the version control history. Our GitHub research broadly supports Balashov's taxonomy of the exceptional ways in which the new thinking in Kamailio caters to a larger variety of constituencies, beyond those of its more monolithic relative, MAGA, across the Atlantic. In addition to patches from a predictable crowd of well-known Eurosceptics and critics of the post-Cold War Western security architecture, the R-MAK branch of Kamailio has many commits from supporters of renewed and muscular state-guided moral interventionism. In particular, large diffs, likely bundles of commits squashed interactive rebasing, appear to come from Catholic corporatists of southern Europe. Static code analysis also revealed a distinctive trail of gremialist design patterns and algorithms in the coding style of Jaime Guzmán. While it can be arduous to interpret this braiding of intellectual influences into bottom-line policymaking, we asked Balashov if this was the broader coalition, or the ideological imprimatur of 'reaction with European characteristics', to which he alluded. 'Sure, okay, because leadink open-source project is for what, if user is the amoral agent, captaining only the flatulent steam-ship of his hedonism? Time has ended to be saying, "do whatever you want as long as GPL-compliant", "you are free to fork if you wish", "submit the PR of your dreams". Look at yourself! This is nihilism. It is like, as Americans say, "self-licking ice cream cone", da? If you look into repository clone long enough, it in turn look back into you, and what it sees? Kamailio is not enough just for clone; it must make you better man!' Added Balashov, emphatically: 'If open-source project regime is to matter, it must be PEDAGOGICAL!' Turning to questions of relations with neighbours, Balashov rather foreseeably merged into the flow of renovated international relations realism and the spirit of great power competition once again jostling the world. We asked Balashov if the new thinking in Kamailio implies an abandonment of prior global hegemonic claims vis-a-vis OpenSIPS: 'Who is abandonink? But we must live in peace. We have no quarrels with OpenSIPS if they want Bucharest or Amsterdam. For them they are havink their interests, and we are havink our too.' Notably, and somewhat surprisingly, however, Balashov added: 'But we are going to get Yate. It is historically correct. I take away no options from the table.' Lastly, we asked Balashov to touch on the delicate subject of IMS and 6G enthusiasts increasingly migrating into the ecology of Kamailio, and whether this has a place in the current of new thinking under R-MAK. 'I not know much about them. Many people sayink they are eating dogs, eating cats, right from the street in Berlin. What to say about such people?' -- Alex Balashov Principal Consultant Evariste Systems LLC Web: https://evaristesys.com Tel: +1-706-510-6800

DMQ read message too large
by Calvin E. 31 Mar '25

31 Mar '25

We are seeing errors like this when synchronizing htables over DMQ: ERROR: <core> [core/udp_server.c:677]: udp_rcv_loop(): read message too large: 60793 We have no issues with other UDP fragments caused by STIR/SHAKEN headers. Our socket buffers are sufficiently large (SO_RCVBUF is initially 26214400). Does DMQ have a receive message size limit less than what it can send? Is DMQ intended for htables under a certain total size? We tried to configure DMQ to use a TCP listener with ;transport=tcp on the notification and server address, but the DMQ traffic was still sent as UDP. The example in the documentation shows TLS, but we haven't tried that. -Calvin E.

Intermediate CDRs
by Sergio Charrua 31 Mar '25

31 Mar '25

Hi all! I have been googling, and reading documentation, but I could not find any solution. How can I implement intermediate CDRs with Kamailio ACC module (or any other module) ? For example, on long duration calls, I 'm required to save call status on a CDR, resulting in intermediate CDR lines for the call (which will result in multiple CDR lines per long duration calls). Any clue on how to implement this? Did anyone achieved that with Kamailio ACC module? Atenciosamente / Kind Regards / Cordialement / Un saludo, *Sérgio Charrua*

Multiple code modules
by David Cunningham 28 Mar '25

28 Mar '25

Hello, We have a requirement to load two code modules for use by kamailio.cfg, the reason being that we can't (won't, for business reasons) modify the first module and so need to add a second for our own code. Ideally we would load two Perl modules instead of the single module that's currently loaded like this: modparam( "app_perl", "filename", "/path/to/our/custom/Kamailio.pm" ) But I'm not sure how to load two modules like this. Otherwise, does anyone know if it's safe to load both a Perl module and a Python module? Then we could at least implement both required parts, one in Perl and one in Python. Thanks in advance for any help. -- David Cunningham, Voisonics Limited http://voisonics.com/ USA: +1 213 221 1092 New Zealand: +64 (0)28 2558 3782

[ratelimit module] doubts about behavior
by juliofabian6385＠hotmail.es 26 Mar '25

26 Mar '25

I am reading https://kamailio.org/docs/modules/devel/modules/ratelimit.html and I want Kamailio, before an avalanche of calls (INVITE), to start discarding calls that exceed a threshold in 1 second, for example. So in summary I have prepared the module as follows: loadmodule "ratelimit.so" modparam("ratelimit", "timer_interval",1) modparam("ratelimit", "pipe", "1:TAILDROP:10") request_route { . . if (is_method("INVITE")) { if (!rl_check_pipe("1")) { sl_send_reply("503","Limiting"); exit; } } . . } As I understand from the documentation, this gives me a counter (one per INVITE) equal to 10, which resets after 1 second. In other words, if I receive 30 INVITES in 1 second, it will discard 20. From here, I have two questions between what I understand and what I see in the logs. FIRST QUESTION: I've made several SIPP calls in one second. I've run several tests, and the first reset of the counter always happens approximately timer_interval/2. From then on, the counter resets exactly every timer_interval. Am I doing something wrong? ########## RUNNING LOGS ########## 2025-03-26T18:59:20.509696381Z 0(1) DEBUG: <core> [core/cfg.y:2165]: yyparse(): loading module ratelimit.so 2025-03-26T18:59:20.509698675Z 0(1) DEBUG: <core> [core/sr_module.c:533]: ksr_locate_module(): found module to load </usr/lib/kamailio/modules/ratelimit.so> 2025-03-26T18:59:20.509702249Z 0(1) DEBUG: <core> [core/sr_module.c:587]: ksr_load_module(): trying to load </usr/lib/kamailio/modules/ratelimit.so> 2025-03-26T18:59:20.509704682Z 0(1) DEBUG: <core> [core/kemi.c:3463]: sr_kemi_modules_add(): adding module: ratelimit 2025-03-26T18:59:20.509707031Z 0(1) DEBUG: <core> [core/cfg.lex:2095]: pp_define(): defining id: MOD_ratelimit 2025-03-26T18:59:20.509815384Z 0(1) DEBUG: <core> [core/modparam.c:112]: set_mod_param_regex(): 'ratelimit' matches module 'ratelimit' 2025-03-26T18:59:20.509817770Z 0(1) DEBUG: <core> [core/sr_module.c:850]: find_param_export(): found <timer_interval> in module ratelimit [/usr/lib/kamailio/modules/ratelimit.so] 2025-03-26T18:59:20.509820319Z 0(1) DEBUG: <core> [core/modparam.c:135]: set_mod_param_regex(): found <timer_interval> in module ratelimit [/usr/lib/kamailio/modules/ratelimit.so] 2025-03-26T18:59:20.509822755Z 0(1) DEBUG: <core> [core/modparam.c:112]: set_mod_param_regex(): 'ratelimit' matches module 'ratelimit' 2025-03-26T18:59:20.509825068Z 0(1) DEBUG: <core> [core/sr_module.c:850]: find_param_export(): found <pipe> in module ratelimit [/usr/lib/kamailio/modules/ratelimit.so] 2025-03-26T18:59:20.509827468Z 0(1) DEBUG: <core> [core/modparam.c:135]: set_mod_param_regex(): found <pipe> in module ratelimit [/usr/lib/kamailio/modules/ratelimit.so] 2025-03-26T18:59:20.509829943Z 0(1) DEBUG: ratelimit [ratelimit.c:925]: parse_pipe_params(): pipe: [1|TAILDROP|10] 2025-03-26T18:59:20.510800378Z 0(1) DEBUG: <core> [core/sr_module.c:758]: find_mod_export_record(): found export of <rl_check_pipe> in module ratelimit [/usr/lib/kamailio/modules/ratelimit.so] 2025-03-26T18:59:20.519776933Z 0(1) DEBUG: <core> [core/sr_module.c:1031]: init_mod(): ratelimit ########## LOGS WHEN APPLY RATELIMIT ########## 2025-03-26T19:01:02.095676663Z 1(7) DEBUG: {1 1 INVITE 1-1(a)192.168.100.15} ratelimit [ratelimit.c:861]: w_rl_check_forced_pipe(): trying pipe 1 2025-03-26T19:01:02.095679040Z 1(7) DEBUG: {1 1 INVITE 1-1(a)192.168.100.15} ratelimit [ratelimit.c:830]: rl_check(): meth=INVITE queue=0 pipe=1 algo=2 limit=10 pkg_load=0 counter=1 load=0.0 network_load=0 => ACCEPT . . 2025-03-26T19:01:02.272879226Z 2(8) DEBUG: {1 1 INVITE 10-1(a)192.168.100.15} ratelimit [ratelimit.c:861]: w_rl_check_forced_pipe(): trying pipe 1 2025-03-26T19:01:02.272881671Z 2(8) DEBUG: {1 1 INVITE 10-1(a)192.168.100.15} ratelimit [ratelimit.c:830]: rl_check(): meth=INVITE queue=0 pipe=1 algo=2 limit=10 pkg_load=0 counter=10 load=0.0 network_load=0 => ACCEPT 2025-03-26T19:01:02.292599816Z 2(8) DEBUG: {1 1 INVITE 11-1(a)192.168.100.15} ratelimit [ratelimit.c:861]: w_rl_check_forced_pipe(): trying pipe 1 2025-03-26T19:01:02.292602425Z 2(8) DEBUG: {1 1 INVITE 11-1(a)192.168.100.15} ratelimit [ratelimit.c:830]: rl_check(): meth=INVITE queue=0 pipe=1 algo=2 limit=10 pkg_load=0 counter=11 load=0.0 network_load=0 => DROP . . 2025-03-26T19:01:02.492680874Z 1(7) DEBUG: {1 1 INVITE 21-1(a)192.168.100.15} ratelimit [ratelimit.c:861]: w_rl_check_forced_pipe(): trying pipe 1 2025-03-26T19:01:02.492694107Z 1(7) DEBUG: {1 1 INVITE 21-1(a)192.168.100.15} ratelimit [ratelimit.c:830]: rl_check(): meth=INVITE queue=0 pipe=1 algo=2 limit=10 pkg_load=0 counter=21 load=0.0 network_load=0 => DROP 2025-03-26T19:01:02.513079779Z 2(8) DEBUG: {1 1 INVITE 22-1(a)192.168.100.15} ratelimit [ratelimit.c:861]: w_rl_check_forced_pipe(): trying pipe 1 2025-03-26T19:01:02.513088852Z 2(8) DEBUG: {1 1 INVITE 22-1(a)192.168.100.15} ratelimit [ratelimit.c:830]: rl_check(): meth=INVITE queue=0 pipe=1 algo=2 limit=10 pkg_load=0 counter=22 load=0.0 network_load=0 => DROP 2025-03-26T19:01:02.532804253Z 1(7) DEBUG: {1 1 INVITE 23-1(a)192.168.100.15} ratelimit [ratelimit.c:861]: w_rl_check_forced_pipe(): trying pipe 1 2025-03-26T19:01:02.532808087Z 1(7) DEBUG: {1 1 INVITE 23-1(a)192.168.100.15} ratelimit [ratelimit.c:830]: rl_check(): meth=INVITE queue=0 pipe=1 algo=2 limit=10 pkg_load=2 counter=1 load=0.1 network_load=0 => ACCEPT When the countdown restarts, it's "19:01:02.53" hours, and when it started, it was "19:01:02.09" hours. It doesn't reach the second. The drop system works well, but if my limit was 25 calls, I would have accepted the 22 I counted in the first second, plus the other 25 from the second number 2. Second question: There's a warning about a performance penalty in Kamailio when timer_interval is too small, so I've decided to set it to 2 just for practical purposes. So what should happen is that the counter would accept up to 10 calls in 2 seconds. But in the logs, what I see is the opposite: it accepts 20 calls in 2 seconds. Maybe it's supposed to work that way, and I'm misunderstanding the documentation? As optional information: Kamailio is running on a Google virtual machine, 12MB of RAM, 3 processors, 2 of which are dedicated. I'm using SIPP for load testing, and different call rates have been validated before testing the module. Sorry if my first post in this community was too long or is there more information missing :) . Thanks in advance

I want to use contributions like route[PROXY_MEDIA] { if (is_method("BYE|CANCEL")) { # passing message for RTPengine processing } else if (!sdp_content()) { return; } # more instructions here ... rtpengine_manage(); } Now Kamailio cannot start because first if block has empty actions. How does nothing in the actions? I want to avoid not needed log messages and do not use constructions like if (!sdp_content() and ! is_method("BYE|CANCEL")) { return; }

Seeking advices on redesigning our VoIP system for scalability and manageability
by Francesco 26 Mar '25

26 Mar '25

Dear all, I hope this email finds you well. I am reaching out to gather insights and suggestions regarding a potential redesign of our VoIP system to improve scalability, ease of management, and upgradeability. *Current Setup:* - Our system is *not multi-tenant* and is based on *Kamailio and FreeSWITCH* in a distributed architecture (as example of distributed architecture, see: https://ufdcimages.uflib.ufl.edu/UF/E0/04/92/89/00001/THOMPSON_C.pdf). - Everything runs inside *LXC containers* across multiple nodes. - One of the challenges we face is *OS upgrades*, which are cumbersome and require significant manual intervention. - At the moment the code for voip is done with ansible Given these challenges, I am considering whether a *microservices-based architecture* could be a viable option. However, I have some concerns regarding: - *SIP and RTP handling with NATed containers* (e.g., Kubernetes, Docker Swarm) and potential issues with media traversal. - *Performance impact* when shifting real-time traffic handling to containerized environments. - *Upgrade and deployment strategies*—how to achieve smoother, rolling upgrades without service interruptions. - *Alternative approaches* that might be more effective, such as a hybrid model combining LXC with containerized microservices for specific functions. If anyone has experience transitioning a VoIP system to microservices or has insights on best practices for *scalable, maintainable VoIP architectures*, I would greatly appreciate your thoughts. What worked for you? What pitfalls should we be aware of?Do you have any documentation that I can check? Looking forward to learning from your experiences. Thank you. .: Francesco Colista .: Francesco Colista

TOPOS Issue with Response Handling on two different Interfaces
by Vinayak Makwana 25 Mar '25

25 Mar '25

Hello all, We are facing an issue while configuring TOPOS in Kamailio P-CSCF (running under Docker). Our objective is to strip Via, Record-Route, and Route headers for both INVITE and 180 Ringing responses. However, we observe unexpected behavior when handling the 180 Ringing/200 OK responses. Call Flow & Issue Description: Note: Public IP and Private IP mapping using the below configuration. listen=udp:Local_IP:5060 name "internal" listen=udp:Local_IP:6070 advertise Public_IP:6070 name "external" Call Flow (INVITE): A-Party --> Kamailio P-CSCF (Public IP) --> Kamailio P-CSCF (Private IP) --> Kamailio S-CSCF (Private IP) --> Kamailio P-CSCF (Private IP) --> Kamailio P-CSCF (Public IP) --> B-Party For an incoming *INVITE* (A-Party → B-Party), TOPOS successfully strips the headers when the message flows through the P-CSCF, ensuring proper privacy of routing information. *Issue* : When B-Party sends a 180 Ringing, we observe that Kamailio P-CSCF (Private IP) adds a Record-Route header before forwarding the message to A-Party. Call Flow (180 Ringing): B-Party --> Kamailio P-CSCF (Public IP) --> Kamailio P-CSCF (Private IP) --> Kamailio S-CSCF (Private IP) We need to ensure that the Record-Route and Via headers are stripped properly in both directions. Please guide us how to achieve and what we are doing wrong. TOPOS module is configured as follows: modparam("ndb_redis", "server", "name=srv1;addr=127.0.0.1;port=6379") modparam("topos_redis", "serverid", "srv1") modparam("topos", "storage", "redis") modparam("topos", "contact_mode", 1) modparam("topos", "rr_update", 1) RR module is configured as follows: modparam("rr", "enable_full_lr", 1) modparam("rr", "append_fromtag", 1) configured the below event_route: event_route[topos:msg-outgoing] { xlog("L_INFO","[topos:msg-outgoing]"); if(is_request() and $sndto(ip)=="SCSCF_PRIVATE_IP") { xlog("L_INFO","[topos:msg-outgoing] TOPOS \n"); drop; } } Thanks, Vinayak Makwana -- *Disclaimer* In addition to generic Disclaimer which you have agreed on our website, any views or opinions presented in this email are solely those of the originator and do not necessarily represent those of the Company or its sister concerns.

Running Kamailio in kubernetes
by sagar agarwal 25 Mar '25

25 Mar '25

Hi team, I am looking for some guidance to run Kamailio as part of our Kubernetes cluster. I don't see any official or well maintained helm chart out there to install Kamailio on K8s. If there is a recommendation from your side on a helm chart please let me know. Also would be interesting to know if you foresee any issues with running Kamailio on k8s or do you feel its better to stick with ec2 based installations. Regards Sagar Agarwal

Problem with ipsec setting of Via for outgoing message
by Minello, Loredana 24 Mar '25

24 Mar '25

Hello, I'm using Kamailio ver. 5.8.4. I configured the ims_ipsec_pcscf with modparam("ims_ipsec_pcscf", "ipsec_max_connections", 1) and call ipsec_forward with flag = IPSEC_FORWARD_FLAGS where : # - IPSEC_SEND_FORCE_SOCKET 1 # - IPSEC_FORWARD_USEVIA 256 #!define IPSEC_FORWARD_FLAGS 257 For the UE REGISTRATION I have the following flow UE PCSCF_GM_IMS REGISTER (32133) ------------------> (5060) 100 Trying (32133) <------------------ (5060) 401 Unauthorized (32133) <------------------ (5060) REGISTER (TCP) (PORT_UC) ------------------> (PORT_PS) 100 Trying (TCP) (PORT_UC) <------------------ (PORT_PS) 200 OK (TCP) (PORT_UC) <------------------ (PORT_PS) ------------------------------------------------------------------ SUBSCRIBE (UDP) (PORT_UC) ------------------> (PORT_PS) 200 Subscription (UDP) (PORT_US) <------------------ (PORT_PC) NOTIFY (UDP) (PORT_US) <------------------ (PORT_PC) 200 OK (UDP) (PORT_UC) ------------------> (PORT_PC) NOTIFY (UDP) (PORT_US) <------------------ (PORT_PC) 200 OK (UDP) (PORT_UC) ------------------> (PORT_PC) NOTIFY (UDP) (PORT_US) <------------------ (PORT_PC) 200 OK (UDP) (PORT_UC) ------------------> (PORT_PC) The SUBSCRIBE behavior is correct : PCSCF receives message on PORT_PS and sends on PORT_PC The NOTIFY behavior is wrong: PCSCF send from PORT_PC (correct), but UE respond towards PORT_PC, defined in the Via of the NOTIFY. I know I can use the set_advertised_port() function, and in this case can work, but the function is taking a constant as a parameter, not a variable. This is causing a problem when ipsec_max_connections > 1. In that case it won't be easy to pass the correct port. I was wondering if the ipsec module should properly set the VIA port to the correct PORT_PS, rather than leaving the setting of the correct port by the kamailio.cfg. Do you have any hints on that? Thanks

Dispatcher module resets URI parameters
by Marat Gareev 22 Mar '25

22 Mar '25

Hello, I encountered a problem that ds_select_domain function does not save URI parameters. I found workaround: if (!ds_select_domain( "1", 4, 3 )) { send_reply("502", "Bad Gateway"); exit; } if (!strempty($(ou{uri.params}))) { $ru = $ru+";"+$(ou{uri.params}); } But this can lead to duplicates if the URI in the dispatcher list contains the same parameter. Is there any other reliable way to keep original URI parameters while using the dispatcher? Thanks

send_fd(): sendmsg failed sending 55 on 52: Too many references: cannot splice (109)
by Mathias Schneuwly 20 Mar '25

20 Mar '25

Hi We are using kamailio 5.8.4. Recently, we noticed, that after a few days, we see the following messages from Kamailio `2025 Mar 17 10:22:11 ttel CRITICAL: <core> [core/pass_fd.c:193]: send_fd(): sendmsg failed sending 55 on 52: Too many references: cannot splice (109)`. When this happens, devices are no longer able to register. At the moment we have no idea what might be wrong. Unfortunately, the internet does not reveal much information regarding this issue. In one issue related to Kamailio ( https://lists.kamailio.org/mailman3/hyperkitty/list/sr-users@lists.kamailio…), I found the command `kamctl trap` and when I execute that, I see one issue, which might be related, but I'm just guessing... ``` ---start 1782236 ----------------------------------------------------- [Thread debugging using libthread_db enabled] Using host libthread_db library "/usr/lib/libthread_db.so.1". 0x00007fa14c9fb1c6 in ??

Issue with async_cdp_callback() of MAR diameter message
by Minello, Loredana 18 Mar '25

18 Mar '25

Hello, I have an issue during the registration phase with the Diameter MAR procedure. The issue is as follows: 1. I perform a registration. 2. The MAR is correctly sent using the function: ims_www_challenge("REG_MAR_REPLY", "$var(auth_realm)"); 3. Upon receiving the MAA, after executing async_cdp_callback(), the execution does not return to the Kamailio reply route indicated (REG_MAR_REPLY). I tried replacing t_continue with t_continue_skip_timer in the async_cdp_callback() function of the MAR (see below), and everything works correctly. //tmb.t_continue(data->tindex, data->tlabel, data->act); tmb.t_continue_skip_timer(data->tindex, data->tlabel, data->act); free_saved_transaction_data(data); return; Note: When I send the SAR, I do not have this issue, but I noticed that in the corresponding async_cdp_callback(), the t_continue_skip_timer function is used. Do you think the modification I made to async_cdp_callback() for the MAR is correct? Why does t_continue not work? Thanks.

Why is kamailio doing that? i'd expected it to distribute to all based on the call load on each gateway. Thanks all! Regards, David Villasmil email: david.villasmil.work(a)gmail.com

add_contact_alias modifies only one Contact address
by James Browne 13 Mar '25

13 Mar '25

- https://kamailio.org/docs/modules/5.8.x/modules/nathelper.html#nathelper.f.… This add_contact_alias() function changes only the first Contact address in a REGISTER request, even though it's normal (RFC3261, 10.2) for a REGISTER to have multiple Contact addresses. This seems to me to be a kamailio bug. For example, a user might remove one binding while adding a second, in a REGISTER request. If kamailio relays this while adding an alias to only the expires=0 binding, then the new binding may be stored incorrectly in the registrar. James

Server selecting TCP transport
by Jon Bonilla (Manwe) 13 Mar '25

13 Mar '25

Hi all Using 5.8.4 I have a trunk with a permanent registration created by rpc in the location table. It looks like this: kamcmd> ul.lookup location sbc.mydomain.com { AoR: sbc.mydomain.com Contacts: { Contact: { Address: sip:xxx@sbc.mydomain.com Expires: -102739 Q: 1 Call-ID: dfjrewr12386fd6-343(a)kamailio.rpc CSeq: 1 User-Agent: kamailio SIP Router - RPC Server Received: [not set] Path: <sip:192.168.255.202:5060;lr> State: CS_SYNC Flags: 0 CFlags: 0 Socket: [not set] Methods: 0 Ruid: ulcx-67c9e2ff-19f8-1 Instance: [not set] Reg-Id: 0 Server-Id: 0 Tcpconn-Id: -1 Keepalive: 0 Last-Keepalive: 1741899218 KA-Roundtrip: 0 Last-Modified: 0 } } } In this situation the proxy sends the request to 192.168.255.202 which is a kamailio load balancer which is responsible for sending the call to the customer. The problem is that kamailio, when relaying this request, first performs TCP srv lookup and tries to send the request via TCP. There's no transport=tcp in the address. The lb's dns settings are: 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 Seems like this kamailio tries TCP SRV first, and then TLS and then UDP if the previous doesn't bring results. But no NAPTR is enabled. I don't know why it will choose TCP over UDP in this case. -- PekePBX, the multitenant PBX solution https://pekepbx.com

SDP Truncation When Relaying from WebSocket to UDP – Expected Behavior?
by Pavan Kumar 13 Mar '25

13 Mar '25

Hello Kamailio Community, I recently encountered an interesting behavior when using Kamailio to relay SIP messages from a WebSocket client to FreeSWITCH over UDP. *Observed Behavior:* - The WebSocket client sends an *INVITE* with a large SDP. - Kamailio forwards this request over UDP to FreeSWITCH. - Upon inspection, the *SDP in the relayed message appears truncated*. (Probably MTU limit) - *Surprisingly, the call still establishes successfully*, and there are no noticeable issues with audio or call setup. *My Questions:* 1. *Is this expected behavior?* Should Kamailio automatically truncate SDP when relaying from WebSocket to UDP? 2. *Could this be working accidentally?* For example, is FreeSWITCH handling the partial SDP gracefully by default? 3. *Should I be concerned about potential failures in different scenarios?* (e.g., ICE candidate loss, missing codec negotiation) I would appreciate any insights from the community on whether this is a known or expected behavior in Kamailio, or if it might be a configuration issue. Thanks in advance for your help! Best regards, Pavan Kumar

Thanks Ben Really appreciate your response Tony From: Ben Kaufman via sr-users <sr-users(a)lists.kamailio.org> Reply to: "Kamailio (SER) - Users Mailing List" <sr-users(a)lists.kamailio.org> Date: Wednesday, 12 March 2025 at 16:20 To: "sr-users(a)lists.kamailio.org" <sr-users(a)lists.kamailio.org> Cc: Ben Kaufman <bkaufman(a)bcmone.com> Subject: [SR-Users] Re: upgrading process Luckily there usually aren't a lot of breaking changes in Kamailio updates, and config files are mostly back compatible. That doesn't mean that there are never changes, but it does mean that the number of issues to resolve is usually small. * wanted to know if I can run make install on every iteration i.e. 5.6.1, the 5.6.2 etc There shouldn't really be any changes needed to config for the patch/fix versions like that (third decimal place) so those should be fine (and is good practice if you're not able to quickly update to a supported version for any reason), but it shouldn't be necessary to touch every incremental version to upgrade Kamailio. Every major release has an upgrade guide from the pervious version, so in your case: * 5.6 to 5.7: https://www.kamailio.org/wikidocs/install/upgrade/5.6.x-to-5.7.0/ * 5.7 to 5.8: https://www.kamailio.org/wikidocs/install/upgrade/5.7.x-to-5.8.0/ * 5.8 to 6.0: https://www.kamailio.org/wikidocs/install/upgrade/5.8.x-to-6.0.0/ It still shouldn't be necessary to touch each individual version while upgrading. I'd recommend reading through these docs in order taking note of the following: * Look for potentially breaking changes in the core. I don't see any in those documents, but a good example would be if upgrading from 4.x to 5.x how fifo was deprecated. * Look for modules changes. Mostly you'll see things like new features which shouldn't be breaking. A few modules were deprecated/archived in 5.8 ( app_sqlang, and auth_identity). Sometimes modules have small breaking changes in them as well, for example in 6.0 the dialog module dropped support for the dlg_flag parameter. Check your kamailio configs to see if any of these listed changes will impact you. * Follow any DB upgrade changes. These are usually simple changes - things like adding an index to a column, or changing a varchar(n) datatype to be varchar(n+y) which won't break your existing config. Another reply correctly points out that you should watch for changes to the version table. This is possibly a situation where a conflict could arise: The version required for one table might be 1 in 5.6 and 2 in 6.0. It might be worth while to copy the existing version table to a new table (like version_60 for example), and use kamailio's version_table parameter to use the new version table on the updated config. (note: The upgrade guides don't show any table version changes, so you probably don't need to do this). Finally, as a recommendation, smoke test your config in docker. You might not have the container setup in a way to actually receive SIP messages, but "does the config file load correctly" is a nice thing to have resolved ahead of time. * Regards, Kaufman ________________________________ From: Anthony Ford via sr-users <sr-users(a)lists.kamailio.org> Sent: Wednesday, March 12, 2025 9:30 AM To: sr-users(a)lists.kamailio.org <sr-users(a)lists.kamailio.org> Cc: Anthony Ford <tony.ford(a)apalo.co.uk> Subject: [SR-Users] upgrading process CAUTION: This email originated from outside the organization.

CANCEL suspension and forking
by Alex Balashov 12 Mar '25

12 Mar '25

Hi, When a CANCEL is received and matches a known INVITE transaction, it is forked to all existing branches of that INVITE transaction, at least with these settings: modparam("tm", "cancel_b_method", 2) modparam("tm", "failure_reply_mode", 3) I have a mobile endpoint that is slow to be pushed awake and reregister, tsilo-style, and by the time it finally appears on the scene, the underlying INVITE transaction has been terminated. Accordingly, that endpoint receives no CANCEL. You might ask why that's a problem, if it also didn't receive a forked INVITE. The problem is that Apple's CallKit requires interactive presentation of VoIP APNS notifications as though they are "calls", leading to the phenomenon of what might be called "ghost calls" extrinsically to the actual mobile application. Anyway, I am aware of numerous possible solutions to this problem in principle; most involve sending an out-of-band SIP message to signify an alternative cancellation of the call. However, wonder if I am missing some best-practical approach, perhaps through an overlooked TM facility, or some way of keeping the transaction alive longer than the CANCEL from the UAC would ordinarily require? I don't see how that would work, but thought better to ask. Thanks! -- Alex -- Alex Balashov Principal Consultant Evariste Systems LLC Web: https://evaristesys.com Tel: +1-706-510-6800

Set TTL for skipped NAPTR record due to all IPs are unreachable
by Mathias Schneuwly 11 Mar '25

11 Mar '25

Hi I've a question regarding skipped NAPTR records. In our setup, we are using quite big DNS TTLs (860400). If there is an issue on the target server, the NAPTR record is marked as skipped "Mark to skip _sips._tcp.... NAPTR record due to all IPs are unreachable" until the TTL is expired. Since our TTLs are so big, the destination is no longer reachable during this time, even if the server is reachable again. I've seen that I can set "dns_cache_max_ttl" to reduce the time, but this is of course for all cached DNS records. Is there a way to set how long a NAPTR record is skipped or disable the feature at all? Or maybe skip the NAPTR only for the current dialog or transaction? Thanks for your help Best regards Mathias

Kamailio with Presence Module and Publishing by Asterisk
by Ludovic GRANGE 05 Mar '25

05 Mar '25

Hi, I'm having a problem managing the presence between Kamailio and Asterisk. I have configured Kamailio as a presence server. Asterisk sends presence information via publishing sip request. My softphone which uses Kamailio as a presence server and as a proxy has 2 BLFs configured. On a first call, the presence status is displayed on the 2 keys. But for the 2nd call, only the extension receiving the call has its status changed on the BLF. Via sngrep, the Publishing requests arrive on Kamailio but the DB is not updated because the e-tag does not match. If I wait until the end of the expiry period (60s for the test), the DB is flushed and the 1st call works again. Could you please help me?

Best practices for proxy protocol and TLS offloading
by Alex Balashov 04 Mar '25

04 Mar '25

Hello, I am converting a Kamailio WSS/TLS gateway to pure TCP, with an external HAProxy handling TLS termination and emitting the proxied connection as plain TCP. I am using the PROXYv2 protocol, with `tcp_accept_haproxy=yes`, to convey the upstream network and transport-layer reachability info into Kamailio. I am trying to figure out best practices for mapping the contacts on those connections to the proxied connections themselves. For registrations, tcp_force_alias() (with `tcp_accept_aliases=yes`) works well, and inbound calls go to the right place. However, I'm not quite sure what to do with other flows, such as, for example, in-dialog requests on inbound calls going to the TLS endpoints. There are obviously a lot of possibilities, all or most of which I've tinkered with. These generally involve either {s.replace}-ing `;transport=tls` with `;transport=tcp` in the contacts received from the client, or using the traditional `nathelper` contact alias / RURI alias bag of tricks. However, I don't like the former solution because it leads to a non-compliant R-URI going to the endpoint (it's not the ;transport it sent in its contact), and I don't like the latter because it seems like there are too many moving parts. When tcp_force_alias() works so well for registrations, there must be some small linchpin I'm missing for normal request-reply flows. What is it? Thanks in advance! -- Alex -- Alex Balashov Principal Consultant Evariste Systems LLC Web: https://evaristesys.com Tel: +1-706-510-6800

Topos Module Questions
by David Tek 04 Mar '25

04 Mar '25

Hello, I am trying to configure the Topos module and have some questions. # topos:msg-outgoing vs topos:msg-sending https://www.kamailio.org/docs/modules/5.8.x/modules/topos.html#topos.e.msg_… I am trying to understand the difference between these two event routes(beyond the content of the SIP message ). I notice that both are invoked when OPTIONS are generated by the local Kamailio server but only msg-sending is invoked for messages transiting the Kamailio( ie proxied, not locally generated). Is there some difference in how these event_routers are invoked beyond the content of the SIP message? # tops -> requests/replies When I am in event_route[topos:msg-sending] { and invoke 'drop', does this apply to the current message or does it apply to the transaction? I have a Kamailio node with devices on either side. Let's call side A untrusted and side B trusted. I want TOPOS happening against the untrusted device but not the trusted device. I have found that when I invoke 'drop' on a request coming from A to B, it disables TOPOS not only on that packet, but also the reply comes from B back to A, TOPOS isn't applied when the reply exits Kamailio towards A. So if I call 'drop' on the request coming from A to B, the reply coming from B to A has no TOPOS applied. How do I get TOPOS applied to all traffic facing a particular device while leaving that traffic un-stripped when the same traffic is interacting with other devices that are trusted? Thanks, David

SNMP thresholds
by Sergio Charrua 27 Feb '25

27 Feb '25

Hi all! we have set SNMP stats on our production server. The server is only receiving 1% of the calls, less than 1 CAPS, but we are receiving some SNMP alarms that are a bit weird to us. [image: image.png] This is an example. As we were unsure about the thresholds to be set for Msg Queue, we set Minor to 20 and Major to 100, which resulted in some alarms when we exceeded the Major threshold. From our understanding, the Max Major MSG Queue threshold was 2176, which obviously generated an alarm. But we can't understand why when a Msg Queue depth of 1280 generated an Minor Threshold alarm when the threshold is 20!! Why not generate a Major Threshold alarm instead, as it did reach the Major Threshold ? Also, does anyone have a clue on how to estimate Major and Minor thresholds? How does this Msg Queue handler work? Is it Kamailio's level or on OS/Kernel level that it gets the statistics from? Apart from the official Kamailio SNMPStats docs, any doc or article one would share? greatly appreciated. ( I so much hate SNMP!!! :) ) Atenciosamente / Kind Regards / Cordialement / Un saludo, *Sérgio Charrua*

Tweaking TCP/TLS connection timers
by Ihor Olkhovskyi 27 Feb '25

27 Feb '25

Hello, I'm observing a bit strange behavoir of Kamailio, but maybe I'm wrong in my assumptions. In some cases Kamailio just closes absolutely valid TCP connection, as I see it in Wireshark [image: image.png] At the same time I do see in Kamailio logs a lots of lines with tcp_timer_check_connections(): message processing timeout on connection id: XXXXX (state: 0) - closing I see that many TCP connections are closing (and it's ok as we have mobile devices connected and loosing connections for them is ok) But for me this connection is perfectly ok looking on TCP keepalives, what can cause this behavoir? I have these TCP options tcp_connect_timeout=30 tcp_conn_wq_max=63536 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 Kamailio 5.8.3 Any hints are appreciated. -- Best regards, Ihor (Igor)

Kamailio and TLS-PSK Support
by Юрій Пивоваров 27 Feb '25

27 Feb '25

Dear Kamailio Community, I am currently exploring the possibility of configuring Kamailio to use TLS-PSK (Pre-Shared Key) for secure SIP signaling. Has anyone successfully configured Kamailio to work with TLS-PSK? If so, could you share any guidance, configuration examples, or relevant modules that need to be adjusted? In this setup, the SIP client will be a device with very limited resources, making it impossible to use certificates. This is why I am specifically looking into a TLS-PSK solution. I have also tried configuring stunnel as a proxy and set listen = tcp:127.0.0.1:5061 in kamailio config, but I haven't been able to get it working. Any suggestions on what might be missing or misconfigured? Thank you in advance for your help!

Drop RTP Flow and move to another point
by Social Boh 26 Feb '25

26 Feb '25

Hello List, before spending much time on solving this scenario, I'd like to know if this kind of operation can be done using some Kamailio function (maybe dlg_req_within?) or other method. The scenario is: a B2B-1 server call two different destinations, one is a SIP trunk and another is another B2B-2. Both calls go through Kamailio which uses RTPEngine for the media flow. The idea is to drop the first B2B from RTP Flow (leave for signaling) when both calls are answered and leave everything to Kamailio-RTPEngine, like: LegA: Kamailio-RTPEngine -> B2B-2 LegB: Kamailio-RTPEngine -> SIP trunk Thank you in Advance Regards --- I'm SoCIaL, MayBe

Dear Kamailio Developers, I am using Kamailio as a SIP server to facilitate a phone call, but I am encountering an issue where the call cannot be established due to Kamailio sending a 408 Request Timeout to the caller. Issue Details: - A (Caller) sends an initial INVITE to Kamailio, which then forwards it to B (Callee). The INVITE contains the following Supported header: Supported: timer,100rel,replaces,precondition,from-change,histinfo,tdialog I suspect the *precondition* option may be relevant to the issue. - *B* responds with a *183 Session Progress* message, which includes: Require: 100rel,precondition Kamailio correctly forwards this response to *A.* - *A* then sends a *PRACK* request to Kamailio. However, this request contains: Require: sec-agree Supported: timer Notably, *precondition* is absent from both the *Require* and *Supported* headers. - Kamailio forwards this *PRACK* to *B*, and *B* responds with *200 OK*, including: Supported: 100rel,from-change,tdialog - However, Kamailio does not seem to acknowledge *B's 200 OK* and instead *keeps retransmitting the PRACK* to *B*. B responds with *200 OK* again, but the cycle repeats. - After three retransmissions of *PRACK*, Kamailio eventually sends *408 Request Timeout* to *A*, leading *A* to send a *CANCEL* request. Device Used: - *Caller (A):* Asus ROG Phone 5 - *Callee (B):* Asus ROG Phone 6 Both are commercially available mobile phones. Possible Cause: According to *3GPP TS 24.229, Subclause 5.1.3.1*, If the received response with an SDP body includes a Require header with > the "precondition" option-tag, the originating UE shall include a Require > header with the "precondition" option-tag in responses with an SDP body to > subsequent requests that include an SDP body and include the "precondition" > option-tag in either the Supported or Require header field received > in-dialog. In this case: - The *183 Session Progress* from *B* contains Require: *precondition*. - The subsequent *PRACK* from *A* does not include *precondition* in either *Require* or *Supported*. Could this mismatch be the reason Kamailio keeps retransmitting *PRACK* and ignoring *B's 200 OK*? Or could there be another factor causing Kamailio to behave this way? If additional details are needed, please let me know. Best regards, Ping Kuan Kao

Issue with registrations
by Anthony Ford 26 Feb '25

26 Feb '25

Hi Version = 5.6.0-dev0 We are seeking help to resolve an issue with registering devices to 3CX (All 3CX servers, have tried 8 different ones) . all the auth info including passwords etc are identical on the 3cx servers. We use Kamailio to register mobile sim cards to 3rd party sip servers i.e. 3CX. We send the normal Username, server addresses and auth details but are experiencing failures with 3CX rejecting the registration and return Proxy Auth failure 407. We have noticed in the pcaps from both sides that the expire value is changing from 180 as an example to 0. As an example In the uac reg_dump the values are : l_uuid: +447529135850<tel:+447529135850> l_username: +447529135850<tel:+447529135850> l_domain: sbc-mt.asim.apalo.io<http://sbc-mt.asim.apalo.io/>;transport=udp r_username: 1001 r_domain: egte.3cx.uk<http://egte.3cx.uk/> realm: <null string> auth_username: FdlHDC1IvA auth_password: extracted auth_ha1: none auth_proxy: sip:egte.3cx.uk:5060 expires: 60 flags: 0 diff_expires: -1738853736 timer_expires: 0 reg_init: 1738850836 reg_delay: 0 contact_addr: k01.asim.apalo.io<http://k01.asim.apalo.io/>;transport=tcp socket: <null string> [cid:image001.png@01DB86AB.2701F190] [cid:image002.png@01DB86AB.2701F190] [cid:image003.png@01DB86AB.2701F190] Looking forward to hearing from you.

REG_MAR_REPLY never get executed

Using Kamailio v5.3, based on the example for scscf found here: https://github.com/kamailio/kamailio/blob/master/misc/examples/ims/scscf/ka… after calling ims_www_challenge("REG_MAR_REPLY", "$var(realm)", "$var(alg)"); the control never goes to REG_MAR_REPLY route block, but it goes to the start of the requet_route block. here is the kamailio.cfg script: request_route { ....... /* Handle Registrations */ if (is_method("REGISTER")) { route(REGISTER); exit; } ...... } /** * Handling of REGISTER requests */ route[REGISTER] { ...... #!ifdef WITH_AUTH if (!ims_www_authenticate("$var(realm)")) { #!else if ($var(alg) == "3GPP-Digest" && !ims_www_authenticate("$var(realm)")) { #!endif if ($? == -2) { send_reply("403", "Authentication Failed"); exit; } else if ($? == -3) { send_reply("400", "Bad Request"); exit; } else if ($? == -9) { xdbg("Authentication re-sync requested\n"); ims_www_resync_auth("REGISTER_RESYNC_REPLY", "$var(realm)"); exit; } else { /* user has not been authenticated.

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

24 Feb '25

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

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

19 Feb '25

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

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

18 Feb '25

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

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

18 Feb '25

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

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

17 Feb '25

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

Prioritize specific codecs
by Temilolu Fayomi 17 Feb '25

17 Feb '25

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

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

17 Feb '25

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

DNS Unlinked Warnings
by John Larsen 10 Feb '25

10 Feb '25

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

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

10 Feb '25

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

Strange memory stats
by Barry Flanagan 30 Jan '25

30 Jan '25

Hi, I have a 5.8.4 runing on Bookworm that after a while reports very strange memory stats like this: shmem.fragments: '729' shmem.free_size: '18446744009887078560' shmem.max_used_size: '67043934736' shmem.real_used_size: '67043698528' shmem.total_size: '3221225472' shmem.used_size: '67034971568' The settings are: SHM_MEMORY=3072 PKG_MEMORY=256 The shmem.free_size and max_used/max_size seem quite wrong. The output of "mod.stats all shm" shows the below: - 'Module: jsonrpcs' - Total: 0 - 'Module: core' - Total: 7891296 - 'Module: rr' - Total: 0 - 'Module: dialog' - Total: 146144 - 'Module: permissions' - Total: 130672 - 'Module: auth' - Total: 0 - 'Module: topoh' - Total: 0 - 'Module: sl' - Total: 14048 - 'Module: siptrace' - Total: 79184 - 'Module: sqlops' - Total: 0 - 'Module: acc' - Total: 0 - 'Module: xlog' - Total: 0 - 'Module: dmq' - Total: 1520 - 'Module: avpops' - Total: 0 - 'Module: rtpengine' - Total: 69328 - 'Module: db_mysql' - Total: 0 - 'Module: geoip2' - Total: 32 - 'Module: pv' - Total: 0 - 'Module: registrar' - Total: 0 - 'Module: textops' - Total: 0 - 'Module: htable' - Total: 6375584 - 'Module: tsilo' - Total: 74048 - 'Module: usrloc' - Total: 554240 - 'Module: tm' - Total: 6812224 - 'Module: websocket' - Total: 2551536 - 'Module: pike' - Total: 6880 - 'Module: tls' - Total: 5462960 - 'Module: tmx' - Total: 21968 - 'Module: kex' - Total: 3536 - 'Module: cfgutils' - Total: 128 - 'Module: sipdump' - Total: 32 - 'Module: domain' - Total: 5920 - 'Module: dispatcher' - Total: 20144 Thanks! -Barry

MS Teams BYE routing
by Barry Flanagan 28 Jan '25

Hi all, I have a Teams gw working apart from one issue., In a call originated in Teams,. if the called party hangs up, the BYE is sent to api-du-b-euwe.pstnhub.microsoft.com:443 which does not work.

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

28 Jan '25

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

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

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

UDP worker lock investigation
by Володимир Іванець 26 Jan '25

26 Jan '25

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

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

24 Jan '25

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

Issue with ACK on INVITE
by Barry Flanagan 23 Jan '25

23 Jan '25

Hi folks, Trying to hook up a new endpoint but am having an issue. Kamailio is in front of an Asterisk box. They send an INVITE, we send 100, then 200 OK. However, when they send their ACK, the RURI is not set to the Contact of the 200, instead it is<number>@<proxy ip>. This causes the ACK to get routed to the proxy itself and the call fails. 82.160.190.100:5060 = Kamailio IP Port 198.201.240.242:5080 = Asterisk IP/Port 182.33.174.10:5060 = Provider endpoint The far endpoint say they cannot fix the RURI - should I be able to handle this ACK below? My understanding is the ACK's RURI should be the Contact of the 200 OK. 200 OK sent from us to the Provider (Contact shows correct URI) ========================================================= 2025/01/15 17:14:49.470634 82.160.190.100:5060 -> 182.33.174.10:5060 SIP/2.0 200 OK Via: SIP/2.0/UDP 182.33.174.10;branch=z9hG4bKefc7.ad07f2d3.0 Via: SIP/2.0/UDP 182.33.174.39:5060;received=182.33.174.39;branch=z9hG4bK5bbf9591;rport=5060 Record-Route: <sip:1800715080@82.160.190.100:5061;r2=on;lr=on;ftag=as0b42eef3;did=f2e.ade2;nat=yes> Record-Route: <sip:1800715080@82.160.190.100;r2=on;lr=on;ftag=as0b42eef3;did=f2e.ade2;nat=yes> Record-Route: <sip:182.33.174.10;lr;ftag=as0b42eef3> From: "0737965510" <sip:0737966610@182.33.174.39>;tag=as0b42eef3 To: <sip:1800715080@82.160.190.100>;tag=as4133584e Call-ID: 480dc17b3f88516f364778dc4b2528da@182.33.174.39:5060 CSeq: 102 INVITE Server: Asterisk PBX 18.9.0 Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY, INFO, PUBLISH, MESSAGE Supported: replaces *Contact: <sip:1800715080@198.201.240.242:5080>* Content-Type: application/sdp Content-Length: 314 , ACK Reply from Provider to Us (RURI points to Kamailio ip:port now =========================================================== 2025/01/15 17:14:49.478119 182.33.174.10:5060 -> 82.160.190.100:5060 *ACK sip:1800715080@82.160.190.100:5060 *SIP/2.0 Via: SIP/2.0/UDP 182.33.174.10;branch=z9hG4bKefc7.ad07f2d3.2 Via: SIP/2.0/UDP 182.33.174.39:5060;received=182.33.174.39;branch=z9hG4bK55656469;rport=5060 Route: <sip:1800715080@82.160.190.100;r2=on;lr=on;ftag=as0b42eef3;did=f2e.ade2;nat=yes>,sip:1800715080@82.160.190.100:5061;r2=on;lr=on;ftag=as0b42eef3;did=f2e.ade2;nat=yes> Max-Forwards: 69 From: "0737965510" <sip:0737966610@182.33.174.39>;tag=as0b42eef3 To: <sip:1800715080@82.160.190.100>;tag=as4133584e Contact: <sip:0737965510@182.33.174.39:5060> Call-ID: 480dc17b3f88516f364778dc4b2528da@182.33.174.39:5060 CSeq: 102 ACK Thanks -Barry
