Recommended openSSL version
by Igor Olhovskiy 19 Oct '22

19 Oct '22

Hello! Due to I still experience irregular Kamailio 5.4 crashes (like 1/month) related to SSL (using websockets and SIPS) I'm wondering, could openSSL upgrade change the situation? As of now in CentOS 7 I have 1.0.2k version. Does anyone have experience to fix crash-related to TLS problems with openSSL upgrade? Or maye some tuneup of TCP parameters can help here?My current setup is quite simple: children=4 enable_tls=yes tcp_accept_no_cl=yes tcp_connection_lifetime=600 tcp_max_connections=998976 # 1000000 - 1024, so we're leaving 1k for system reserve tls_max_connections=998976 Number of clients ~ 200 constantly connected to websocket. -- Best regards, Igor

Siremis JSONRPC problem on Bullseye
by Joseph Goettgens 12 Sep '22

12 Sep '22

I am not sure what I have to look for and I didn't change the initial config files (except for the 666 mode for kamailio_rpc.sock). As far as Kamailio is concerned the socket files files do exist: root@deb11srv1-kamailio:/var/www/siremis-5.3.x# ls -l /run/kamailio/ insgesamt 4 srw------- 1 kamailio kamailio 0 7. Jun 11:37 kamailio_ctl -rw-r--r-- 1 kamailio kamailio 5 7. Jun 11:37 kamailio.pid prw-rw---- 1 kamailio kamailio 0 7. Jun 11:37 kamailio_rpc.fifo srw-rw-rw- 1 kamailio kamailio 0 7. Jun 11:37 kamailio_rpc.sock When I look at siremis/log/ERR.log I repeatedly get: '06/07/2022','09:43:29','ERR','ErrorHandler','socket_bind(): unable to bind address [2]: No such file or directory','' This disappears when I put the local file socket in /tmp: <UnixSockLocal name="unixsocklocal" address="/tmp/siremis_rpc.sock" timeout="3.0"/> which was probably done this way in previous versions of Siremis (before systemd private tmp config). In this case I get no error messages, but still no answers (as expected). The next step seems to get UnixSockLocal right.

Newbie - Installation Issue - ERROR: could not load the script in /usr/lib/kamailio//kamctl/kamdbctl.mysql for database engine MYSQL
by p.t.crossley＠gmail.com 02 Aug '22

I suspect this must have been addressed before but I couldn't find a way of searching Archives. I'm using Alpine Linux. Used "apk add kamailio" to install Kamailio 5.5.4-r1 Following the Instructions on https://kamailio.org/docs/tutorials/5.5.x/kamailio-install-guide-git/ At the section for "Creating MySQL database" I modify the file and then run kamdbctl create ERROR: could not load the script in /usr/lib/kamailio//kamctl/kamdbctl.mysql for database engine MYSQL ERROR: database engine not loaded - tried 'MYSQL' I checked the /usr/lib/kamailio//kamctl/ directory and the file wasn't there I suspect I'm missing a module but there aren't any other packages listed for Kamailio at pkgs.alpinelinux.org Thanks for your help P Crossley

Limit cps per destination gw
by Jon Bonilla (Manwe) 02 Aug '22

02 Aug '22

Hi I'm thinking on having a cps preference for each pstn gw that I can check. I've started thinking in the pike module but it won't allow me to set custom cps per peer. seems that the threshold is global. Ratelimit module needs the queues to be set as modparam, not dynamic AFAICS. Any hints? cheers, Jon -- PekePBX, the multitenant PBX solution https://pekepbx.com

Sharing Database between three kamailios
by Waqar 40 01 Aug '22

01 Aug '22

I have three Kamailios in three different servers which are dispatching calls to 9 asterisks in three different servers using load balancing. All these Kamailios are using databases installed on that servers. As the entries of the dispatcher table are the same for all the Kamailio, so I want that these Kamailio use a single database installed on one of the servers. All these Kamailios instances should use the same database which is common between them. And also I want these Kamailios to write into the database by creating a table that stores all the active calls in three Kamailios. Is it possible? How can I do it? Please guide me with somewhat explanation as I am not this much expert in Kamailio. Waiting for a quick response. Regards VoIP Engineer Vicky

Kamailio behind NAT
by Алексей Якимкин 29 Jul '22

29 Jul '22

Hello, I have kamailio in local network behind NAT. Kamailio have one interface eth1 with ip 10.130.0.23 UserAgent - (internet) - (178.0.0.169)router_with_NAT - (LAN) - kamailio+rtpproxy - pbx I made two listeners: listen=udp:10.130.0.23:5070 #to pbx in lan (I don`t want to put via header with 178.0.0.169) listen=udp:10.130.0.23:5060 advertise 178.0.0.169:5060 #to internet (UserAgent need to get via header with 178.0.0.169 ) mhomed = 1 # I think It not useful for my case UserAgent send Register and Invite to 178.0.0.169:5060, Kamailio get it on udp:10.130.0.23:5060 Kamailio Relay it to udp:10.130.0.23:5070 My pbx get requests from udp:10.130.0.23:5070 with via header 10.130.0.23 Responses to UserAgent go from udp:10.130.0.23:5060 with via 178.0.0.169 In RELAY block: if ($Ru == «udp:10.130.0.23:5070») { #set_send_socket(«udp:10.130.0.23:5060»); $fs = «udp:10.130.0.23:5060»; #force_send_socket(«udp:10.130.0.23:5060»); } else { #set_send_socket(«udp:10.130.0.23:5070»); $fs = «udp:10.130.0.23:5070»; } #$fs = «udp:10.130.0.23:5070»; if (!t_relay()) { sl_reply_error(); } route[REGISTRAR] { if ($rd == "mydomain.ru" || $rd == "mydomain2.ru") { set_send_socket("udp:10.130.0.23:5070"); } } It works for requests from UserAgent to PBX. But INVITE from my pbx to UserAgent goes only through udp:10.130.0.23:5070 , Kamailio realy it to internet from udp:10.130.0.23:5070 I get error in syslog: (pv [pv_branch.c:62]: pv_get_branchx_helper(): error accessing branch [0]) I tried set_send_socket(«udp:10.130.0.23:5070»); and $fs = «udp:10.130.0.23:5070»; Why I can`t relay outgoing requests to internet through another socket? -- Best regards, Alex

[REGISTRAR] Registered. How to match $sut to usrloc received ?
by Richard Edmands 29 Jul '22

29 Jul '22

Hey Kamailio Users, So the scenario is we get the registers. Load them, slightly oddly as we also fill in the received section, not something I usually do. Then when they send an invite, the To and From headers are real phone numbers and for some reason the contact header isn't their username. So to compensate for that I'm trying to match their connection ($sut) using registered, but after a couple of hours I haven't been able to get it to match up. Not sure what I'm missing. ul.dump gets me Received: sip:sipclientpublicip:2353;transport=udp so we know that part is loading $sut correctly into the user location data. modparam("usrloc", "matching_mode", 2) modparam("registrar", "xavp_rcd", "ulrcd") modparam("registrar", "received_avp", "$avp(i:42)") $xavp(regcfg=>match_received) = $sut; if (registered("location","$sut", 2, 1)) { After that block of code $sut is sip: sipclientpublicip:2353;transport=udp which is what's in usrloc for received, but it's not match. There's probably a much smarter way of doing this that I've completely missed, if so then that'd be excellent. But if I'm on the right path somewhat then it would be great to get this working.

[UAC] How to get the outbound registration status of uac.reg_active?
by Denys Pozniak 28 Jul '22

28 Jul '22

Hello! I have several Kamailio sharing a common uacreg table and use the RPC interface to enable and disable outgoing registration on nodes depending on the cluster status: *kamcmd uac.reg_active 0kamcmd uac.reg_active 1* https://kamailio.org/docs/modules/stable/modules/uac.html#uac.r.uac.reg_act… How can I get the current status of uac outbound registration (to get 0 or 1)? -- BR, Denys Pozniak

Re: [SR-Users] TLS connection failure. Not sure if system behavior is correct.
by Ahmed Fouad 27 Jul '22

27 Jul '22

Hi, You are currently using TLSv1/SSLv3 ECDHE-RSA-AES256-GCM-SHA384 256 Teams stopped TLSv1/ TLSv1.1 and only allowing TLS1.2+ So change your TLS settings to enforce it only method = TLSv1.2+ after restarting kamailio your teams connections should be good.

27 Jul '22

HI I’m trying to get CDR function. I would like to have one CDR for whole call at the syslog. I use: …… loadmodule "db_text.so" loadmodule "dialog.so" loadmodule "acc.so" …….. # -----Dialog module ----- modparam("dialog", "db_mode", 0) # -----ACCounting module ----- modparam("acc", "early_media", 0) modparam("acc", "report_cancels", 1) modparam("acc", "log_facility", "LOG_LOCAL1") modparam("acc", "detect_direction", 0) modparam("acc", "log_level", ACC_LOG_LEVEL) modparam("acc", "log_flag", FLAG_ACC_LOG) modparam("acc", "log_missed_flag", FLAG_ACC_LOG_MISSED) modparam("acc", "failed_transaction_flag", FLAG_ACC_LOG_FAILED) modparam("acc", "log_extra", "ip_src=$si;ip_dst=$avp(ip_dst);sip_from=$fU;sip_to=$tU;ruri_user=$rU;spx_rs=$avp(spx_http_rs)") ## TODO modparam("acc", "cdr_enable", 1) modparam("acc", "cdr_enable_log", 1) modparam("acc", "cdr_facility", "LOG_LOCAL1") request_route { if (is_method("INVITE")) { setflag(FLAG_ACC_LOG); setflag(FLAG_ACC_LOG_MISSED); setflag(FLAG_ACC_LOG_FAILED); } At the kamailio.log I see only transaction for INVITE, but I wait for some CDR for all dialog. Whats wrong in my config? -- -- Олег Подгуйко
