Kamailio : Serial forking

21 Mar '22

I've been trying to do serial forking, I've configured something that is working but when I'm looking on github and other sources it seems like my code is a little too complicated and I would like to know if there is a simpler config that I can use. To have more precision, I'm using RTPENGINE and I need to be able to go through NAT. My Config : request_route { route(INVITE); exit; } route[INVITE]{ route(RECORD_ROUTE); route(GROUP_RELAY_SER); switch($tU) { case "112": // This number does not exist (It's not a subscriber). xlog("MY_SEVERITY"," -- Calling Group Serial"); route(GROUP_RELAY_SER); break; case "113": xlog("MY_SEVERITY"," -- Calling Group Parralelle"); route(GROUP_RELAY_PAR); break; default: xlog("MY_SEVERITY"," -- Calling Someone"); route(LOCATION); route(RELAY); } exit; } route[RECORD_ROUTE]{ # - remove preloaded route headers remove_hf("Route"); if(is_method("INVITE|SUBSCRIBE")) { # record routing for dialog forming requests (in case they are routed) record_route(); } } route[GROUP_RELAY_SER]{ t_on_reply("MANAGE_REPLY"); route(IPV4V6); route(NATMANAGE); (RTP Routing is working correctly) append_branch("sip:9919995@192.168.1.41","1"); append_branch("sip:9919992@192.168.1.41", "0.2"); append_branch("sip:75575757@192.168.1.41", "0.4"); append_branch("sip:9919991@192.168.1.41", "0.5"); t_load_contacts(); t_next_contacts(); while(!route(GROUP_LOCATION)) { if (!t_next_contacts()) { send_reply("408","Timeout or nobody available"); exit; } } t_on_failure("GroupFailureRoute"); #Relay (aka Forward) the request t_relay(); break; } # User location service route[GROUP_LOCATION] { $avp(oexten) = $rU; if (lookup_branches("location")){ return (1); } else { return (-1); } } failure_route[GroupFailureRoute]{ t_next_contacts(); while(!route(GROUP_LOCATION)){ if (!t_next_contacts()) { send_reply("408","Nobody available"); exit; } } t_on_failure("GroupFailureRoute"); t_relay(); } # Manage incoming replies in transaction context onreply_route[MANAGE_REPLY] { if(status=~"[12][0-9][0-9]") { if(has_body("application/sdp")){ setbflag(FLB_BRIDGE); } route(NATMANAGE); } } --------------------------------- Here's The SIP Trace : 2022/03/21 18:28:45.265009 149.154.195.121:9665 -> 192.168.1.41:5060 INVITE sip:112@192.168.1.41:5060;transport=TCP SIP/2.0 Via: SIP/2.0/TCP 100.79.133.159:5060 ;branch=z9hG4bK-524287-1---75083bb7c6ed8a35;rport Max-Forwards: 70 Contact: <sip:9919993@100.79.133.159:5060;transport=tcp> To: <sip:112@192.168.1.41:5060> From: "codec3-public"<sip:9919993@192.168.1.41:5060 ;transport=TCP>;tag=35ce2334 Call-ID: RtH8fBIrIgUYPAkxlxjI4Q..

Can Kamailio send an ACK to a final response?
by Marrold 21 Mar '22

21 Mar '22

Hello, I'm exploring using Kamailio as a dumb edge proxy, and as such I want to keep things as lean as possible. In some scenarios I would like the "core" proxies to signal to the edge that a request should be dropped without a response. This could be with a custom header in the reply or perhaps a 444 response ( nginx uses this internally to drop a request without responding ) I have discovered that if I drop the response in the reply_route, the edge proxy doesn't send an ACK and keeps retransmitting the request until it times out, at which point it sends a 408 back to the UA. Is there any way to ACK the response from the core and destroy the transaction? Thanks Matthew

Kamailio WebRTC Call Not Working
by Ankit Jayswal 21 Mar '22

21 Mar '22

Hi, I have configured Kamailio to register a SIP user over websocket. SIP users are getting registered over webphone like JSSIP fine but not able to establish the call scenario below. >From Twilio Trunk - INVITE - KAMAILIO - ASTERISK - play hello world - Dial SIP user 101@Kamailio_IP - Rings 101 and Answer - Hangup. Here, 101 is registered with Kamailio IP, and I am sending a call from Twilio SIP trunk to Kamailio server IP. Asterisk is on port 5080 and Kamailio is on port 5090 both are on the same host 45.118.163.244. This above call scenario is NOT working with Webphones registered via JSSIP. I think the second call leg from Asterisk -> Kamailio is not getting set up properly and ACK is not getting confirmed here, call connects for some time and no voice transmits and then disconnects. The same call scenario is working with users registered at Softphone like Zoiper perfectly fine. No idea why it is not working with a webphone. I have attached kamailio.cfg, Kamailio log and Asterisk's pjsip logs here. So, please guide me on this as soon as possible. -- Thanks & Regards, *Ankit Jayswal* | Specialist - Software Development

dialog module issues (BYE Request issued) when topos is enabled
by Patrick Karton 19 Mar '22

19 Mar '22

i am using dialog and topos module. but i have an issue i think with topos module. When topos module is disabled all the call flow works well but when i enable topos module i have this weird behaviour : after Caller sends BYE and complete the call , i receive later a BYE Request issued by the dialog module towards Caller and Callee. Does anyone already had that issue ? modparam("dialog", "enable_stats", 1) modparam("dialog", "hash_size", 1024) modparam("dialog", "rr_param", "oovdlg") modparam("dialog", "dlg_match_mode", 1) modparam("dialog", "db_mode", 0) modparam("dialog", "db_update_period", 30) modparam("dialog", "wait_ack", 1) modparam("dialog", "ka_timer", 10) modparam("dialog", "ka_interval", 30) modparam("dialog", "profiles_with_value", "concurrent_calls") modparam("dialog", "end_timeout", 180) modparam("dialog", "default_timeout", 3600) modparam("dialog", "noack_timeout", 90) modparam("dialog", "early_timeout", 300) modparam("dialog", "dlg_extra_hdrs", "X-OOV-Hint: Dlg-hit\r\n") modparam("db_text", "db_mode", 0) modparam("db_text", "emptystring", 0) modparam("db_text", "file_buffer_size", 8192) modparam("db_text", "max_result_rows", 1000) modparam("topos", "storage", "db") modparam("topos", "db_url", "text:///home/sbc/database") modparam("topos", "mask_callid", 0) modparam("topos", "sanity_checks", 0) modparam("topos", "contact_mode", 0)

DMQ version compatability
by Ben Kaufman 19 Mar '22

19 Mar '22

Daniel, In a recent thread you stated the following regarding DMQ compatibility between versions: "if you do dmq replication between kamailio systems running different major versions, then it is likely to get memory leaks due to replication of data and most probably cannot be fixed. This is because internal structures of modules (also dmq commands) can change, practically what an instance does is not ensured to happen on the other instance. Just for example, from my mind, htable got some changes during past releases, dmq also has significant enhancements by getting support for more transport protocols." Is it possible to get a bit more clarification on this, particularly as it relates to DMQ_USRLOC? I'm hoping to do rolling updates, but don't want to end up in a situation where I've caused myself more problems than I've solved. Ben Kaufman

help to configure topos module configuration
by Patrick Karton 18 Mar '22

18 Mar '22

Caller <--> (internal_IP) Kamailio (external_IP) <---> Callee I have this set up of kamailio with 2 interfaces. i use topos module for topology hiding and what i want to do is to send external_IP in Contact Header of request relayed to Callee and internal_IP in Contact Header of response relayed to Caller. i noticed that : when i use topos module with contact_mode to 0 all Record-Route and Caller Via Header are removed and thats great. but i dont find way to put 2 different ip addresses in Request and Response Contact Header? when i use contact_mode to 2 Record-Route and Caller Via Header are not anymore removed thats bad for topology hiding. And its seems we can not use $xavu(_tps_=>contact_host) parameter of module to put 2 different ip addresses in Request and Response Contact Header. What i want is : - remove all Record-Route and Caller Via Header for request like when contact_mode to 0 - and put 2 different ip addresses in Request and Response Contact Header is it possible to achieve it ? Thanks.

Upgrading from version 5.2 to 5.4 - any unpublished words of wisdom?
by Kevin Greene 18 Mar '22

18 Mar '22

Hi: I have a 5.2 version of Kamailio running and I was thinking to get it upgraded to the 5.4 branch. The 5.2 is working well but I have heard the 5.4 is a bit more stable. Thus the question becomes, is it worth the risk to upgrade and what should I look out for. Thanks. Kevin

Dialog module and DMQ
by Olle E. Johansson 18 Mar '22

18 Mar '22

Hi! The documentation on the DMQ support in the dialog module is a bit short, so I will ask here for clarifications: If I want to enable a rough limit on concurrent calls - will all servers share a $DLG_count ? Will get_profile_size() return the number of dialogs belonging to a profile on ALL servers? Thank you! /Olle

Kamailio as stateless failover proxy server and nat
by ppq＠tuta.io 17 Mar '22

17 Mar '22

Hello, I need some help in creating a stateless failover balancer for two asterisk servers using kamailio. I followed in the steps of an old project here: https://txlab.wordpress.com/tag/xlab1/ Kamailio is running in a multihomed host, with public ip facing the internet and private ip facing the asterisk servers. I have partial issues with nat traversal when the external device is also behind nat. All works when the device initates a call/dialog, however when the asterisk server tries to send an "OPTIONS" keep alive to the end device, Kamailio receives the packet from asterisk but tries to send it to the private IP address of the device instead of the public ip:port. Same goes for calls. My kamailio.cfg is below. I am missing something obvious here, but can't find it. Thanks === CUT==== #!KAMAILIO ################################################################ # # This is a front-end SIP proxy configuration for the xlab1 project # See for more details: https://txlab.wordpress.com/tag/xlab1/ # The configuration requires Kamailio version 3.3.x # # This work is licensed under a Creative Commons Attribution 3.0 License # Author: Stanislav Sinyagin <ssinaygin(a)k-open.com> # ################################################################ #!define WITH_DEBUG ####### Defined Values ######### #### define DBURL "text:///opt/sipfe/etc/kamailio_db" #!define DBURL "text:///etc/kamailio/kamailio_db" #!define BACKEND_NET4 10.10.10.0/24 #!define BACKEND_NET6 2a02:200:8:100::/64 ####### Global Parameters ######### #!ifdef WITH_DEBUG debug=2 log_stderror=yes #!else debug=1 log_stderror=no #!endif memdbg=5 memlog=5 log_facility=LOG_LOCAL0 fork=yes children=2 auto_aliases=no #listen=udp:195.x.x.78:5060 # to avoid simple attacks, use unconventional port #port=5060 # this makes it listen on all ipv6 addresses auto_bind_ipv6=0 dns_try_ipv6=no # let kamailio choose the right source IP address mhomed=3 # life time of TCP connection when there is no traffic # - a bit higher than registration expires to cope with UA behind NAT tcp_connection_lifetime=3605 ## Hardening sip_warning=0 server_signature=no user_agent_header="User-Agent: Kamailio Failover Balancer" ####### Modules Section ######## ## NOTE: ## mpath="/opt/sipfe/lib64/kamailio/modules_k/:/opt/sipfe/lib64/kamailio/modules/" loadmodule "db_text.so" loadmodule "jsonrpcs.so" #loadmodule "mi_fifo.so" loadmodule "tm.so" loadmodule "kex.so" loadmodule "sl.so" loadmodule "rr.so" loadmodule "pv.so" loadmodule "maxfwd.so" loadmodule "textops.so" loadmodule "siputils.so" loadmodule "xlog.so" loadmodule "sanity.so" loadmodule "ctl.so" loadmodule "cfg_rpc.so" #loadmodule "mi_rpc.so" loadmodule "path.so" loadmodule "domain.so" loadmodule "dispatcher.so" loadmodule "nathelper.so" loadmodule "rtpproxy.so" #!ifdef WITH_DEBUG loadmodule "debugger.so" #!endif # ----------------- setting module-specific parameters --------------- #modparam("mi_fifo", "fifo_name", "/tmp/kamailio_fifo") # add value to ;lr param to cope with most of the UAs modparam("rr", "enable_full_lr", 1) # do not append from tag to the RR (no need for this script) modparam("rr", "append_fromtag", 0) modparam("nathelper", "received_avp", "$avp(RECEIVED)") modparam("nathelper", "nortpproxy_str", "a=sdpmangled:yes\r\n") modparam("path", "use_received", 1) modparam("domain", "db_url", DBURL) modparam("dispatcher", "db_url", DBURL) modparam("dispatcher", "table_name", "dispatcher") modparam("rtpproxy", "rtpproxy_sock", "udp:127.0.0.1:22222") #modparam("rtpproxy", "rtpproxy_sock", "unix:/var/run/rtpproxy/rtpproxy.sock") #!ifdef WITH_DEBUG # ----- debugger params ----- modparam("debugger", "cfgtrace", 1) #!endif ####### Routing Logic ######## route { if (!sanity_check()) { exit;

kamctl or kamcmd way to enable/disable sections of configs
by Joshua Young 17 Mar '22

#!define MYSECTION" route("1"); #!ifdef MYSECTION route("2"); #!endif I have declarations like this in my kamailio.cfg file, and was curious if there was a way to use kamctl or kamcmd to enable or disable the defined value in a live system. Or if there is another approach/mechanism I'm unaware of the "Serial Forking Based on Q Value" stuff and use it in other parts, but I am looking for a general way to manually manipulate routing on live system using cli commands if possible...

properly removing First Via header received

i want to remove the First Via Header received from uac to kamailio. so in my script i use remove_hf("Via") but in the relayed request i see that ";received=x.x.x.x;rport=xxxx" is left without any header before it. i think internally kamailio adds a lump before i call the remove_hf function. how to do it properly ?

WebSocket ping is not being sent
by Xuo Guoto 14 Mar '22

14 Mar '22

Hello list, I have kamailio 5.5.3 (x86_64/linux) configured as an SBC in front of asterisk to front end webrtc clients. Browser clients running JsSIP 3.7.0 connect to kamailio via webrtc and kamailio sends the traffic back to asterisk using SIP. rtpengine is configured to relay the RTP packets. I need to send websocket pings every 10 seconds to the browser clients. I have the following config in kamailio: modparam("websocket", "keepalive_mechanism", 1) modparam("websocket", "keepalive_timeout", 10) modparam("websocket", "keepalive_interval", 2) modparam("websocket", "keepalive_processes", 2) modparam("websocket", "verbose_list", 1) If my understanding of the documentation is correct, I do not need to do any additional configuration. But looking at the websocket traffic, I do not see any ping packets in websocket. I am also using sipdump module to capture all packets sent and received by kamailio and the ping packets are not visible there either. What could be wrong here? Do I need to do any additional config? Thanks for every help! X.

Have a need to strip out various parameters from the user portion of the RURI and/or the To (npdi, etc). Does anyone have any clever methods for doing so that don't involve just brute forcing through the individual parameters?

Kamailio + RADCLI
by Marrold 11 Mar '22

11 Mar '22

Hi, We're currently testing Kamailio 5.5.3 on Debian 11 compiled with RADCLI and we're experiencing an issue with radius authentication: Feb 23 08:54:22 redacted /sbin/kamailio[817172]: WARNING: <script>: RADIUS auth failed for redacted (IP:redacted:5060) Feb 23 08:54:22 redacted /sbin/kamailio[817173]: radcli: rc_avpair_new: rc_avpair_new: no attribute 1/1 in dictionary Feb 23 08:54:22 redacted2 /sbin/kamailio[817173]: ERROR: auth_radius [sterman.c:204]: add_cisco_vsa(): unable to add Cisco-AVPair attribute I don't believe this is directly a Kamailio issue but enabling debug logging hasn't revealed any clues ( The log lines remain the same without additional info ) This was working previously on 5.5.X on Debian 9 Has anyone experienced this before or have any suggestions on where to start looking? Thanks

Kamailio 5.5 TLS critical log in Debian 11
by mayamatakeshi 11 Mar '22

11 Mar '22

I'm testing with this kamailio version: $ kamcmd version kamailio 5.5.4 (x86_64/linux) 54c9df on: $ cat /etc/issue Debian GNU/Linux 11 \n \l with: $ openssl version OpenSSL 1.1.1k 25 Mar 2021 Whenever I start kamailio I get 3199 log lines like this: 2022-03-10T10:04:39.700676+09:00 lab002201-flip-server /usr/local/src/git/kamailio-5.5/src/kamailio[261703]: CRITICAL: <core> [core/mem/q_malloc.c:519]: qm_free(): BUG: freeing already freed pointer (0x7f8eb57f7848), called from tls: tls_init.c: ser_free(323), first free tls: tls_init.c: ser_free(323) - ignoring I searched the issues at github and found: https://github.com/kamailio/kamailio/issues/2560 https://github.com/kamailio/kamailio/issues/2912 So I tried to start kamailio with --atexit=no but those logs remain. With and without using --atexit=no there is no crash and all my tests are OK. But should I be worried to put this in production?

add a=fmtp: if it does not exist in sdp
by Krzysztof Drewicz 11 Mar '22

11 Mar '22

Hello i try to fix one endpoint, it does neet do have a a=rtpmap:116 telephone-event/8000 a=fmtp:116 0-15 sometimes i got: a=rtpmap:115 telephone-event/8000 and sometimes: a=rtpmap:114 telephone-event/8000 a=fmtp:114 0-15 so - should i use txtops and search for fmtp, and use search_append_body ? ifsearch_body(re) does not find 'a=fmtp:95' (95..127 - dynamic payload here), or am I reinventing the wheel again ? Any hints? -- Krzysztof Drewicz Senior Infrastructure Administrator CLUDO | ul. Grochowska 306/308, 03-840 Warszawa t+48221223977 kdrewicz(a)cludo.pl | www.cludo.pl

Diversion Header & Header management - $hdrc
by Brandon Armstead 10 Mar '22

10 Mar '22

Thanks for your time in advance! When dealing with multiple headers in different formats, i.e. Diversion: <sip:foo>, <sip:bar> $hdrc(Diversion) returns 1 header instead of 2. Is this expected behavior? What is the best way to manage all scenarios of possible multiple header values? It seems currently there is no easy way to iterate over ALL diversion headers, including scenarios like the following below: Diversion: <sip:abc> or Diversion: <sip:abc>, <sip:def> or Diversion: <sip:abc> Diversion: <sip:def>, <sip:ghi> etc. - Brandon

rtpengine - SRTP <> RTP missing a=crypto
by Rhys Hanrahan 09 Mar '22

09 Mar '22

Hi Everyone, I have Kamailio sitting between MS Teams and Asterisk, and using rtpengine to terminate SRTP on Kamailio so that all my internal traffic is unencrypted. My current config works fine for inbound calls where I initiate the INVITE and Teams responds, but if Teams sends the INVITE I am having an issue where SRTP cannot finish negotiating. Non SRTP calls work fine with RTPEngine as well, so it's just the RTP to SRTP I am struggling with. According to this I believe I must pass a=crypto in response to the INVITE which also has a=crypto: https://www.dialogic.com/-/media/1f8b54b43087407d9c2b38846c5c2cb5.ashx?h=40… You can see that in the initial invite from Teams, I get RTP/SAVP with a=crypto, but I do not send one in my OK response after 183 Session In Progress. As below - I am wondering if it's because not all audio channels seem to be getting swapped to SAVP? I'd like to do a generic SRTP <> RTP bridge config (I've tried below). However, I am not 100% sure on how to detect when to swap between AVP and SAVP, so I've also tried just doing rtpengine_manage() and relying on other code to swap between SAVP or AVP *only* when going to/from Teams to keep it simple. I also tried both with and without "replace-origin replace-session-connection ICE=remove" but I still get the same behaviour in all cases.

Kamailio + KEMI + topos + change_reply_status
by Marrold 09 Mar '22

09 Mar '22

Hi, I'm using Kamailio 5.5.3 with a KEMI / Python based configuration on Debian 11. In my reply route I am trying to convert a 183 to a 180 with: KSR.textopsx.change_reply_status(180, "Ringing") I've noticed with TOPOS enabled, it doesn't work and I still see a 183 go out. But with it disabled, it works as expected and it's converted to a 180. I get the same behaviour with / without msg_apply_changes() Config looks like this: def ksr_onreply_manage(self, msg): KSR.info(f"ksr_onreply_manage\r\n") scode = KSR.pv.get("$rs") if KSR.permissions.allow_source_address_group()<0: if scode == 183: KSR.info(f"ksr_onreply_manage: Converting 183 to 180\r\n") KSR.textopsx.change_reply_status(180, "Ringing") KSR.textopsx.msg_apply_changes() if scode>100 and scode<299 : self.ksr_route_natmanage(msg) return 1 The debug log doesn't reveal anything too obvious, I can share if its of any use. Does anyone have any suggestions? Thanks Matthew

kamailio.cfg : behind the NAT (listen and advertise) understanding
by Youssef Boujraf 07 Mar '22

07 Mar '22

Hi Dear I am trying to understand how "listen" and "advertise" work for sip signaling purpose ( corebooks : listen <http://www.kamailio.org/wiki/cookbooks/5.4.x/core#listen> and advertise ) Flow : kamailio behind NAT using softphones on private and public networks. - kamailio : Network : IPv4_private 192.168.1.6 / IPv4_public kamailio.cfg : listen=udp: IPv4_private: 5060 advertise IPv4_public : 5060 - uac (softphone) : zoiper, microsip, cisco spa508g USE CASE : I 'd like to force all softphone on the same local network to reach kamailio through a public ip address. ??? QUESTION : Do I need to REGISTER on IPv4_private address of Kamailio OR REGISTER on IPv4_public address of kamailio or DEFINE another "listen" with another PORT WITHOUT "advertise" for softphone on same kamailio network ? listen=udp: IPv4_private: 5060 advertise IPv4_public : 5060 listen=udp: IPv4_private: 5066 Do I need to use "kamctl ps" to verify which interface is listening on port ? Thanks in advance Best Regards, Youssef BOUJRAF Email: yboujraf(a)gmail.com

simple GUI for Kamailio as a SBC - could be paid
by Krzysztof Drewicz 05 Mar '22

05 Mar '22

Hello, We searched for a simple GUI that could drive a kamailio - a bunch of trunks, some custom logic, tried to use open source Sipwise C5 - a way too big and heavy. Any hints ? links ? Mabe a paid subscription? Our goal is - to have a GUI that could - put a version number to configuration, and have a simple way to audit changes - only to log - what was done, when and from which management account. vi + svn/git - it's working but this is no GUI, ACLs in sqlite, also work, but - need to have a ssh console, keep files in some repository - well this is simply inconvenient when you have more than 5 trunks with registration etc...

t_on_failure => what variables being reset to which values?
by Benoît Panizzon 01 Mar '22

01 Mar '22

Hi List We t_on_failure re-route calls to another destination in case one fails for example announcement servers... Before sending to the announcement server I do add some extra header to define which announcement in which language should be played: append_hf("IMP-annc: $avp(announcecode)\r\n"); append_hf("IMP-mandate: $avp(mandate)\r\n"); append_hf("IMP-language: $avp(callerlang)\r\n"); Also $rU is being set prior to sending the call to the announcement server. Now one of our announcement servers became unavailable and t_on_failure was triggered. The 2nd announcement servers was receiving the calls without any of the additional header and with the 'inbound' $ru without the altered $rU https://www.kamailio.org/docs/modules/devel/modules/tm.html#tm.f.t_on_failu… I'm a bit confused by that, as this states the URI is reset to the value it had on 'relaying'. Is this on 'inbound replaying' or on 'outbound relaying' when route(RELAY) was called to send the call TO the first annoucement server? Is there a bit more specific information on that behaviour? -- Mit freundlichen Grüssen -Benoît Panizzon- @ HomeOffice und normal erreichbar -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________

KEMI jsdt CommonJS-based module
by Ian Carlson 01 Mar '22

01 Mar '22

Greetings, I'm new to Kamailio and working to add Kamailio to an existing Asterisk solution. I'm attracted to the idea of routing via KEMI jsdt since our Asterisk ARI is using nodejs. Playing with KEMI jsdt I was trying to use require() to break up the monolithic routing script. It seems that Kamailio uses Ducktape 2 without module-node or module-ducktape, requiring all routing in a single file? I'd appreciate any suggested practices for managing Kamailio configurations. Cheers, Ian

RTP Engine early media issue one to many
by Filippo Graziola 28 Feb '22

28 Feb '22

Hi everyone, in my environment (kamailio - http API for retrieve destinations - rtpengine) it is used a lot parallel forking, the flow is as follows: A -> INVITE -> Kamailio -> http API/rtjson / t_relay -> Kamailio -> client B / C / D (only one accepting the call) Kamailio loops to itself to have a parallel forking, it involves rtpengine correctly. Both audio and video work during call. The issue comes with one of destinations sending 183 with SDP, the caller will send then a video preview as early media before call is established. I noticed that only the first one "asking" for early media is receiving this video preview (sometimes none of clients requesting it), all others are ignored by caller. This is a case of 1-to-many, I searched a lot about this but it seems at least not working or not supported, could you confirm that there is no configuration trick possible to make work this early media to many destinations? Another issue in above call flow, is that if client B is receiving correctly this early media video and client C answers the call (200OK) client C does not see any video, audio working and video is completely missing from rtp, only a reinvite makes possible to see video. Is this a client side only issue (so only solution is the reinvite) or there is something missing on my kamailio configuration? Thanks Filippo

ACK and DNS failover
by Julien Klingenmeyer 25 Feb '22

25 Feb '22

Hello, I use DNS failover feature for routing some calls, and I wonder about its limitations. I noticed that INVITE and ReINVITE requests are correctly routed based on SRV priority/weight in case of failure, but ACK requests do not use them. Let’s say I have Kamailio A relaying requests to a pool of Kamailios B1 and B2 in TLS. DNS records are the below ones. kamailiob.net. 60 NAPTR 20 100 S SIPS+D2T _sips._tcp.kamailiob.net. _sips._tcp.kamailiob.net. 60 SRV 1 10 5061 kamailiob-1.net. _sips._tcp.kamailiob.net. 60 SRV 2 10 5061 kamailiob-2.net. If B1 is down, I expect requests being relayed to B2 (because of priority 2 in the SRV record). * For initial INVITEs: R-URI is sip:kamailiob.net * If B1 is down, the request is retried to B2 => OK * For in-dialog requests: Route header in incoming request is sip:kamailiob.net so it is set as next destination with loose_route function * If B1 is down, the request is retried to B2 for ReINVITE => OK * But once the ACK comes in, with the same Route header (sip:kamailiob.net), Kamailio tries to send it to B1 only (no retries to B2, and even no retransmissions to B1 either). * When B1 is back UP again a few seconds later, Kamailio does not try to relay the ACK again. The ACK request is attempted to be retransmitted only once to B1. It fails and no more retries after that. Is it the expected behavior? Or is it something misconfigured on Kamailio A? Or is it a TLS connection issue? Here is the DNS configuration on Kamailio A (TM module is enabled): dns_try_naptr=yes use_dns_failover=yes use_dns_cache=yes dns_srv_lb=yes enable_tls=yes tcp_max_connections=4096 tls_max_connections=4096 tcp_reuse_port=yes tcp_connect_timeout=10 tcp_send_timeout=10 tcp_connection_lifetime=3600 I had a look into the DNS tutorial (https://github.com/kamailio/kamailio/blob/master/doc/tutorials/dns.txt) without finding any hint about this. If anyone has already played with SIP DNS failover in Kamailio, your help would be appreciated, thanks! Julien

kamailio and certificate renewal
by Aymeric Moizard 25 Feb '22

25 Feb '22

Hi all, I'm switching my kamailio to use Let's Encrypt certificates. Do I need to force a restart of kamailio when the certificate is renewed or will this be automatic? The doc indicates that reload is possible (but not advised) but it looks to be for a "configuration change" (tls.cfg file change) and not for certificate change. Maybe certificates are automatically reloaded? Regards Aymeric -- Antisip - http://www.antisip.com

ARI app extension is 3802 My problem is that Kamailio LB only works when I try to connect with Asterisk1 and Asterisk2 or Asterisk1 and Asterisk3. If I have two Asterisks in dispatcher.list, it doesn't work and it appears *SIP/2.0 401 Unauthorized* in sip packets capture log. Kamailio version: 5.5.2 Kamailio.cfg modparam("dispatcher", "list_file", "/etc/kamailio/dispatcher.list") modparam("dispatcher", "flags", 3) modparam("dispatcher", "xavp_dst", "_dsdst_") modparam("dispatcher", "xavp_ctx", "_dsctx_") # Dispatch requests route[DISPATCH] { # round robin dispatching on gateways group '1' if(!ds_select_dst("1", "4")) { send_reply("404", "No destination"); exit; } xdbg("--- SCRIPT: going to <$ru> via <$du> (attrs: $xavp(_dsdst_=>attrs))\n"); t_on_failure("RTF_DISPATCH"); route(RELAY); exit; } # Try next destionations in failure route failure_route[RTF_DISPATCH] { if (t_is_canceled()) { exit; } # next DST - only for 500 or local timeout if (t_check_status("500") or (t_branch_timeout() and !t_branch_replied())) { if(ds_next_dst()) { xdbg("--- SCRIPT: retrying to <$ru> via <$du> (attrs: $xavp(_dsdst_=>attrs))\n"); t_on_failure("RTF_DISPATCH"); route(RELAY); exit; } } } dispatcher.list # setid(int) destination(sip uri) flags(int,opt) priority(int,opt) attrs(str,opt) 1 sip:10.148.0.31:5123 1 sip:10.148.0.44:5123 Thanks, Warawich
