Kamailio : Serial forking
by Paclinio 21 Mar '22

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;
