kamailio as proxy for sipclients behind NAT without rtpproxy
by Karthik Kondapaneni 28 Oct '18

28 Oct '18

I want to use kamailio as a forwarding proxy infront of SIP registrar like asterisk/freeswitch without any rtpproxy to reduce the load on server and to be able to handle more requests . I am using default kamailio config file registration is working fine but call is not connecting . So sip clients should register on asterisk(or freeswitch) and able to receive inbound calls too . I am interested in only REGISTER & INVITE messages to restrict the messages based on sipclient's source ip . Please can someone help me with a working configuration for this setup . This is the topology .. (Sipclients with or without NAT ) ---------> (Kamailio without rtpproxy)-------------->(Asterisk or freeswitch or anyother sipserver )

Postgres: server version < 9.5 does not support insert_update
by Minh Phan 25 Oct '18

25 Oct '18

Hello List, I have just installed the version 5.1.6 and I get this warning message when Kamailio starts: > db_postgres_new_connection(): server version < 9.5 does not support insert_update Does it mean Kamailio will not be working properly with my current Postgres Server (9.4)? What are the consequence of not having support for insert_update command? Best regards, Minh Phan

Kamailio Slack channel
by Alex Balashov 25 Oct '18

25 Oct '18

Hi, I'd like to submit for the community's consideration the idea of having a Kamailio Slack channel. Emmanuel Schmidbauer took the initiative to create one: https://kamailio.slack.com/ The sign-in link is: https://join.slack.com/t/kamailio/shared_invite/enQtNDY1NDc5MzMwNDIzLWJlNTF… I for one think this is a good idea and, even if it doesn't ultimately get traction, it should be seriously considered by all. Yes, I am aware of the open-source-purist objection to Slack; it is proprietary and perceived to be a "walled garden" of sorts. Furthermore, for those of us who have been on the Internet and involved in technology for a significant amount of time, the irony is not lost that it is little more than a packaging of the "IRC" experience in the bloated form of a modern JavaScript application. I am also very reluctant to contribute in any way to the Balkanisation or fracturing of project-related communication channels. That thought gives me no comfort. These are all concerns of which I'm mindful. Nevertheless: - A great deal of professional real-time messaging and communication in many organisations has moved to Slack. This is also true of our company, and most companies we work with. Thus, a Slack channel for Kamailio would be highly complementary to a platform many other people are already using. - Slack provides a polished and cohesive user experience, which is why it has become so popular. There are clients for every platform, and a seamless user experience that is also highly compatible with mobile and tablet. One can shoehorn IRC into these media, but it clearly is not designed for them. - There are already lots of open-source discussion channels and developer forums on Slack. - Slack's inline Markdown and other conveniences make it _much_ easier to have discussions about code, configurations, etc., since it is easy to insert inline monospace and multiline blobs, attachments, etc. This is what inspired my switch to it. - A lot of people positioned within the current wave of thinking about IT and technology, and thus a big part of our candidate user base, have never used IRC. Anyway, for those interested, I propose that you join Emmanuel and I.

Why set this flag on registration?
by Isaac 25 Oct '18

25 Oct '18

Hello, In the example for a dual-stack IPv6/IPv4 Kamailio setup here: https://kb.asipto.com/kamailio:kamailio-mixed-ipv4-ipv6 the "FLB_IPV6" flag is being sent on IPv6 registrations. Why set this flag on IPv6 registrations? If I understand correctly, registration requests never make it beyond !save("location so it's not like the flag can be used further in the dial-plan. The code in question: route[REGISTRAR] { if (is_method("REGISTER")) { if(isflagset(FLT_NATS)) { setbflag(FLB_NATB); # uncomment next line to do SIP NAT pinging ## setbflag(FLB_NATSIPPING); } if(af==INET6) setbflag(FLB_IPV6); if (!save("location")) sl_reply_error(); exit; } } Any help is appreciated. Thanks

Kamailio Question
by Brian Longwell 25 Oct '18

25 Oct '18

I'm trying to setup a simple proxy with NAT/RTPproxy. I have started with the basic cfg file and added nat and forced rtpproxy. The proxy is to reside in between endpoints and multiple SIP servers. Currently calls from endpoints are working great but my issue is calls from the server to the endpoint. The SIP messages are good until the 200 OK sent from the phone back, Kamailio is not fixing the contact so it's sending the private IP of the phone back to the server so all subsequent traffic is attempting to route to the private IP. I have tried using the fix_nated_contact everywhere I could think but still no difference. Attached is sip capture and the kamailio.cfg i'm currently using. Thank you, Brian

RtpEngine and iLBC support
by Lars Olsson 25 Oct '18

25 Oct '18

Hi, Can anyone give a quick answer regarding RtpEngine and support for iLBC codec? I have followed the instructions how to build and enable codecs according to the GitHub manual. But iLBC codec is missing when performing "rtpengine --codecs". I have tried to google around for iLBC references, but the only thing that I have found so far is libilbc, which is a lib for ffmpeg, and it looks like ffmpeg needs to be recompiled. What is the correct/fastest way forward for getting iLBC support on RtpEngine on debian 9? The purpose it to test a-law to iLBC transcoding. Best Regards, Lars

Odd behavior comparing strings
by Duarte Rocha 25 Oct '18

25 Oct '18

Greetings, I found an odd behaviour in Kamailio and i would like to know if it's intentional. I've made this snippet for showing : $var(teste) = $null; if($var(teste) == "Test") { xerr("TEST : If returned true"); } The "if" returns true if the $var is $null or 0. I'm using the "cmp_str()" now in order to avoid this issue. Best Regards, Duarte Rocha

Re: [SR-Users] : hight shared memory usage

Hello, No, both server have the same script, the only difference is that they are connected to different DB.

Hello Laurent, TLS is using more memory than TCP and than UDP, due to the higher workload and overhead for crypto/connection tracking. But looking to your registered user count this should not make a big difference in the end. Do you have maybe a different usage pattern on the first proxy comparing to the second one? So that different parts of the cfg or the code are executed? Why do you increased the number of max TLS connections on the first proxy, you had also some issues here? > First proxy (with high memory usage): > > > [cycle #: 3; if constant make sure server lives] Kamailio Runtime > Details: > kamailio 5.0.6 (x86_64/linux) > now: Wed Oct 24 15:18:55 2018 > up_since: Wed Oct 24 13:21:12 2018 > uptime: 7063 > > Transaction Statistics: > tmx:UAS_transactions = 56240 tmx:active_transactions = 4 > tmx:UAC_transactions = 0 tmx:inuse_transactions = 18 > > Stateless Server Statistics: > sl:sent_replies = 134317 sl:sent_err_replies = 0 > > UsrLoc Statistics: > usrloc:location_ch-contacts = 1463 usrloc:location_ch-users = 1181 > usrloc:location_ch-expires = 1076 usrloc:registered_users = 1181 > > Core Statistics: > core:rcv_requests = 214220 core:rcv_replies = 179145 > core:fwd_requests = 5495 core:fwd_replies = 73 > > Shared Memory Statistics: > shmem:fragments = 529 shmem:real_used_size = > 15862690496 shmem:free_size = 36566109504 shmem:total_size = > 52428800000 shmem:max_used_size = 16198927224 shmem:used_size = > 15854961104 > > > > cat /proc/net/netstat | cut -d" " -f12-17 ; cat /proc/net/sockstat TW > TWRecycled TWKilled PAWSPassive PAWSActive PAWSEstab > 339118 0 684 3195 0 4648 > InBcastOctets OutBcastOctets InCsumErrors InNoECTPkts InECT1Pkts > InECT0Pkts > 14620680 0 0 19142166496 9683 133135 > sockets: used 1951 > TCP: inuse 1029 orphan 0 tw 2 alloc 1036 mem 15 > UDP: inuse 540 mem 446 > UDPLITE: inuse 0 > RAW: inuse 0 > FRAG: inuse 0 memory 0 > > > > ------------------------------------------- > > > Second proxy (memory is OK) : > > [cycle #: 2; if constant make sure server lives] Kamailio Runtime > Details: > kamailio 5.0.6 (x86_64/linux) > now: Wed Oct 24 15:19:39 2018 > up_since: Mon Jul 2 00:31:48 2018 > uptime: 9902871 > > Transaction Statistics: > tmx:UAS_transactions = 86712048 tmx:active_transactions = 92 > tmx:UAC_transactions = 0 tmx:inuse_transactions = 178 > > Stateless Server Statistics: > sl:sent_replies = 641635175 sl:sent_err_replies = 0 > > UsrLoc Statistics: > usrloc:location-contacts = 3971 usrloc:location-users = 3845 > usrloc:location-expires = 286685 usrloc:registered_users = 3845 > > Core Statistics: > core:rcv_requests = 752644955 core:rcv_replies = 1181197213 > core:fwd_requests = 14482059 core:fwd_replies = 206909 > > Shared Memory Statistics: > shmem:fragments = 28437 shmem:real_used_size = 56447456 > shmem:free_size = 2091036192 shmem:total_size = 2147483648 > shmem:max_used_size = 82099768 shmem:used_size = 43354160 > > > cat /proc/net/netstat | cut -d" " -f12-17 ; cat /proc/net/sockstat TW > TWRecycled TWKilled PAWSPassive PAWSActive PAWSEstab > 273625 0 0 0 0 3524 > InBcastOctets OutBcastOctets InCsumErrors InNoECTPkts InECT1Pkts > InECT0Pkts > 2010 0 1 179031265416 81564 21432766 > sockets: used 4964 > TCP: inuse 576 orphan 0 tw 3 alloc 681 mem 105 > UDP: inuse 3908 mem 3117 > UDPLITE: inuse 0 > RAW: inuse 0 > FRAG: inuse 0 memory 0 Best regards, Henning -- Henning Westerholt - https://skalatan.de/blog/ Kamailio security assessment - https://skalatan.de/de/assessment

DMQ and DIALOG
by Phillman25 Kyriacou 24 Oct '18

24 Oct '18

Hi List! I currently have 3 Kamailio's (Version 5.1) in an ACTIVE-ACTIVE-ACTIVE scenario behind a load balancer all 3 nodes are listening and advertising the same virtual ip of the load balancer. Im using dmq module together with dialogue module to sync the state of the dialog to all 3 nodes. Is there a way or module that i can use to also sync every transaction? Problem that im facing right now is that an INVITE will come to Kamailio1 and the 100 TRYING or 183 RINGING or 200OK will go to Kamailio2 and since Kamailio1 hasn't received a response will retransmit the INVITE. Or is there a way with dmq to also update the other nodes for responses like 100 ,183 or 200 OK so that Kamailio1 knows not to retransmit? Maybe im going down the wrong path? :) Any assistance would be greatly appreciated My config for dmq and dialog: #=====================DIALOG==================================== modparam("dialog", "enable_dmq", 1) #=====================DMQ======================================= modparam("dmq", "server_address", "sip:x.x.x.x:5080") modparam("dmq", "notification_address", "sip:y.y.y.y:5080") modparam("dmq", "multi_notify", 1) modparam("dmq", "num_workers", 4) modparam("dmq", "ping_interval", 30) request_route { # MANAGE ALL DIALOGS dlg_manage(); if(is_method("KDMQ")) { dmq_handle_message(); } Thanks!

: hight shared memory usage
by Laurent Schweizer 24 Oct '18

24 Oct '18

Dear all, I have 2 proxy running and we have a very big difference of memory usage between them, moreover we have more connected users on the proxy with less memory usage. We have this issue on the first proxy, today we have to increase the shared memory as it was no more possible to setup new TCP connection. We use the same version of the proxy, script is quite the same, one difference, on the proxy with the issue we increase the number of max TLS connection to 20K Any idea ? is TLS consuming more memory than TCP or UDP ?

Double Session Description Protocol Version (v) 0 data when using rtpengine
by Wilkins, Steve 24 Oct '18

24 Oct '18

I was looking at the sdpops_mod.c code hoping that there was an easy way to remove a sess_version (Session Description Protocol Version (v): 0) structure, but there does not appear to be that functionality in that module. It might be a bit of work to remove a duplicate sess_version line. I am using Kamailio 5.1, does anyone know if this is an issue in later versions? Thank you, -Steve

Info: Pre-announcement about Kamailio World 2019
by Daniel-Constantin Mierla 24 Oct '18

24 Oct '18

Hello, being asked couple of times recently, for now I am sending a short note to say that the next edition of Kamailio World Conference is likely to take place at the same location in the city center of Berlin, Germany, during May 6-8, 2019. There are still some bits to sort out before making the dates final, so just have the dates in mind at this moment. Once all is set from organising point of view, we will make the official announcement.

htable 1 Millon registers
by Mauricio Tejeda 23 Oct '18

23 Oct '18

Good afternoon. Trying to use the htables module to load an extensive table in memory, I can not start kamailio. If the table contains few records (5 and 10 in my examples), this works without problems, for everything else I lose the connection to the database "Lost connection to MySQL server during query" I modified the timeout of mariadb but I can not work. Someone with a similar problem or ideas on how to solve it? Thank you

RTPEngine set IDs
by Alex Balashov 22 Oct '18

22 Oct '18

Hi, I have a question about RTPEngine set IDs: As of Kamailio 5.x, it appears the RTPEngine module has got quite smart. Even if I don't set `setid_avp`, it still knows which RTPEngine instance and set ID was engaged by an initial rtpengine_offer() / rtpengine_manage() command. This knowledge persists even to delete calls in CANCEL / BYE handling, or in subsequent offer/answer calls in reinvites or UPDATEs. That's great, and very convenient. It saves me the trouble of having to store the set ID in an RR param or as a dialog variable, because everything Just Works. The problem, of course, is that if I restart Kamailio, all this state is forgotten. So, for example, if I set up a call, answer it, restart Kamailio, then hang it up, the delete command will go to the default set and not necessarily the non-zero set chosen. If I want proper RTPEngine call teardown to persist across restarts, as far as I can tell I will need to store the set ID in an RR param or some other reasonably stateless way. Am I missing anything here? Does the `rtpengine` module offer some means of persisting this data across restarts? As far as I can tell, its database backing is for the set definitions only and not for call state.

kamailio + asterisk + webrtc
by arish haque 22 Oct '18

Hi all, I am using kamailio as sip server and asterisk as media server behind pf-sense firewall (NAT) with a public ip. Sip signalling as well as rtp packets are flowing correctly when the endpoints are within a network. But when trying from outside network sip signalling is working perfectly but there is no RTP. Public ip behind pfsense -> 182.70.xx.yy kamailio+rtpengine and asterisk servers are on private ips --> 192.168.1.x kamailio ip - 192.168.1.x asterisk ip - 192.168.1.y Please, feel free to ask for more information. Thanks & Regards, Arish Haque
