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. Any advice appreciated, as this is my first time dealing with SRTP (and rtpengine). Feeling very stuck.

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

Dispatcher Load Balance with SIP Trunk
by warawich 24 Feb '22

24 Feb '22

Hello, I would like to do a load balance between Asterisk SIP trunks. You can see a diagram from this link: https://drive.google.com/file/d/1Qy66L5rQCfxysYQpSd2-ek_8-by0T8PR/view?usp=… SIP Packets capture log: https://drive.google.com/file/d/1CHGUOwoRDAC93MMBtyfa8gBISKIVC-ng/view?usp=… Details 1. Asterisk1 makes SIP trunk connection with Kamailio. 2. Kamailio makes SIP trunk connection with Asterisk2 and Asterisk3 3. Caller register SIP phone with Asterisk1 Caller extension = 8002 4. Asterisk2 makes a blind transfer to Kamailio. (Call to 8009 then transfer to ARI APP) exten = 8009,1,Transfer(SIP/3802@<kamailio public IP>) 5. 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.

SQLOPS sql_query_async() not functioning in an async manner?
by Ben Kaufman 23 Feb '22

23 Feb '22

I'm not sure if this is by design or not. I have things I want to log to a SQL DB, but it's not nearly as important as call handling, so the sql_query_async() function looked ideal, but in testing, if the DB is not responsive, the call processing gets blocked. In the example below, I'm using just a short hostname which isn't resolvable, but if I have an IP address there that isn't really assigned (for example if the DB server is down), the same blocking behavior is exhibited, but the error is slightly different (can't connect instead of unknown host). Here's my config. This specific simple config was tested on Kamailio 5.5, but I observe similar behavior (in a more complicated config) in the dev branch as well. - - - - #!KAMAILIO async_workers=2 loadmodule "db_mysql" loadmodule "sqlops" loadmodule "sl" loadmodule "xlog" loadmodule "pv" force_rport=yes ## Host sql does not resolve. modparam("sqlops","sqlcon","cb=>mysql://kamailio:kamailiorw@sql/kamailio") ## But start anyways. modparam("sqlops", "connect_mode", 1) request_route { sl_send_reply("100", "Trying"); ## Prevent re-transmissions from the UAC xlog("L_NOTICE", "Time before sql_query_async(): [$TV(Sn)]\n"); sql_query_async("cb", "INSERT INTO table1 (col) VALUES ('val')"); xlog("L_NOTICE", "Time before sl_send_reply(): [$TV(Sn)]\n"); sl_send_reply("404", "Not found"); } Here's the log if I send a simple INVITE with SIPp. Note the timestamps 9(16) NOTICE: <script>: Time before sql_query_async(): [1645574694.546165] 9(16) ERROR: db_mysql [km_my_con.c:163]: db_mysql_new_connection(): driver error: Unknown MySQL server host 'sql' (-3) 9(16) ERROR: <core> [db.c:319]: db_do_init2(): could not add connection to the pool 9(16) ERROR: sqlops [sql_api.c:190]: sql_reconnect(): failed to connect to the database [cb] 9(16) ERROR: sqlops [sqlops.c:232]: sql_check_connection(): failed to connect to database 9(16) ERROR: sqlops [sqlops.c:264]: sql_query_async(): invalid connection to database 9(16) NOTICE: <script>: Time before sl_send_reply(): [1645574699.552440] Ben Kaufman Sr. VoIP Engineer - BCM One +1.612.735.9309 bkaufman(a)bcmone.com<mailto:bkaufman@bcmone.com> 24 hour client support: +1.855.639.6300 [https://www.bcmone.com/files/bcmone-logo.png]<https://www.bcmone.com/> [https://www.bcmone.com/files/twitter-icon-circle.png] <https://www.facebook.com/bcmonenyc/> [https://www.bcmone.com/files/twitter-icon-circle.png] <https://twitter.com/bcm_one/> [https://www.bcmone.com/files/linkedin-icon-circle.png] <https://www.linkedin.com/company/business-communications-management/> NOTE: This e-mail and any attachments are from BCM One, Inc. and are intended solely for the use and review of the individual(s) to whom it is addressed.

kamailio :?==?utf-8?q? ROUTE[AUTH] - IPAUTH - use case

Dear, I enabled two softphone with ADDRESS. - codec1 : ip 192.168.30.241/32 5060 - codec2 : ip 192.168.30.242/32 5060 I enable one softphone with SUBSCRIBER - codec3 : is registered (login/passwd) codec4 is not part of the domain, is not subriber and address. Kamailio proxy - kamailio : ip 192.168.30.240/32 5060 In the kamailio.cfg ROUTE[AUTH]# IP authorization and user authenticationroute[AUTH] {#!ifdef WITH_AUTH #!ifdef WITH_IPAUTH if((!is_method("REGISTER")) && allow_source_address()) { # source IP allowed return; }#!endif if (is_method("REGISTER") || from_uri==myself) { # authenticate requests if (!auth_check("$fd", "subscriber", "1")) { auth_challenge("$fd", "0"); exit; } # user authenticated - remove auth header if(!is_method("REGISTER|PUBLISH")) consume_credentials(); } # if caller is not local subscriber, then check if it calls # a local destination, otherwise deny, not an open relay here if (from_uri!=myself && uri!=myself) { sl_send_reply("403","Not relaying"); exit; } #!else # authentication not enabled - do not relay at all to foreign networks if(uri!=myself) { sl_send_reply("403","Not relaying"); exit; } #!endif return;} Regarding the condition #!ifdef WITH_IPAUTH if((!is_method("REGISTER")) && allow_source_address()) { # source IP allowed return; }#!endif USE CASE : If codec4 (not registered or same domain) tries to INVITE codec3 (in subscriber) the codec, an INVITE MESSAGE is sent and the codec3 could ACK. - But I don't want to allow the INVITE, I 'd like to not allow the codec4 to reach codec3. - But if codec1 or codec2 tries to reach codec3, kamailio will allow the INVITE. Best Regards, -- Youssef BOUJRAF
