how approach nathelper when using usrloc db_mode 3?
by Albert Petit 01 Dec '11

01 Dec '11

Hello, We found an issue when using nat pinger Previously our system had 1 Kamailio as entry point and we were using usrloc in mode 2 so: modparam("usrloc", "db_mode",2) modparam("usrloc", "db_url", "mysql://openser:openserrw@<DB_IP>/openser") On our system we like to use the pinger NAT_HELPER module to keep the connections alive for the users of our system. Now we're trying to configure two Kamailio K1 and K2 as entry point of the system and having both of them active at the same time with a virtual IP as common entry point for both. I believe this approach requires to flush information on the usrloc immediately because following use case can happen and needs to work: - A registers on K1 server - B registers on K2 server -After 5 seg B makes an INVITE to A through K2=> we need K2 kamailio instance to be able to locate A immediately and not wait until the first Kamailio flushes the info to the db. (it looks to be around 20/30 seg by default on mode 2 I think , correct so this looks to be too much time) So to improve this we tried to change to use usrloc in mode 3 instead of mode 2. But then we've a big issue: when enabling the pinger module for NATted users we see it opens a new connection to the db for each OPTIONS ping we want to send. That looks too many connections for our MySQL server because for eg if I leave two users registered for 1 hour after some time I start to see errors like: 13(5292) ERROR: <core> [db_query.c:130]: error while submitting query 13(5292) ERROR: usrloc [dlist.c:151]: raw_query failed 13(5292) ERROR: nathelper [nathelper.c:3459]: failed to fetch contacts 13(5292) ERROR: db_mysql [km_dbase.c:117]: driver error on query: Too many conne How should this problem be approached? Could this be due to wrong mysql configuration? But anyway if for each ping done by NAT_PINGER we make a query to the db I think this is a lot of "noise" for the db as pings happen often! Thanks BR Albert

using kamailio as load balancer
by Albert Petit 29 Nov '11

29 Nov '11

Hello, I'm trying to setup kamailio as load balancer Behind that load balancer I've a registrar and a presence server. When I start a client for the REGISTER and subscribe messages all looks to work fine. The messages from clients are properly balanced to the backend and responses are forwarded properly to the clients. However when my presence server sends a NOTIFY I find the load balancer module answers 404 message to the presence server. I'm thinking the problem is front-end kamailio cannot locate users. I am quite newbie to use Kamailio for this purpose so sorry if what i'm saying contains a big mistake. My load balancer script looks as following: log_facility=LOG_LOCAL0 fork=yes children=4 listen=10.1.1.63:6666 listen=10.1.1.63:5060 alias=dev.myenvironment.net <http://dev.genaker.net> mpath="/usr/local/lib/kamailio/modules_k/:/usr/local/lib/kamailio/modules/" loadmodule "xlog.so" # ----------------- setting module-specific parameters --------------- #!define WITH_DISP #!ifdef WITH_DISP loadmodule "dispatcher.so" loadmodule "db_mysql.so" #!endif # ----- dispatcher ----- #!ifdef WITH_DISP # Set database used for dispatcher servers. As we will use default values, no further # information is needed modparam("dispatcher", "db_url","mysql://openser:openserrw@10.1.1.50/openser ") #!endif ####### Routing Logic ######## route{ #!ifdef WITH_DISP if( uri=~"sip:.*session=chat.*" ) { xlog("L_DEBUG", "PoC:relaying chat session by Request URI"); ds_select_dst("1", "3"); forward(); } else { xlog("L_DEBUG", "PoC:relaying PoC Session by round-robin"); ds_select_dst("1", "4"); forward(); } #!else xlog("L_DEBUG", "PoC: Relaying by hardcoded route"); t_relay("10.1.1.50", "6666"); #!endif } ~ So the questions are: Does this module need to locate users? Should I include usrloc module iin that sip proxy node in order to be able to locate the users?? Thanks Albert

Hi, sorry for spamming again but I'm not being able to register to a SIP provider populating the uacreg table, I followed the steps of this guide: http://by-miconda.blogspot.com/2010/10/best-of-new-in-kamailio-310-10.html, but I don't see any change neither any REGISTER packet sent out to the sip provider, is something missing? How can I know if the values from the table are being loaded? What are the fields: "l_uuid" and "l_username" for? Is for routing incoming calls? I would appreciate any kind of help.

db_mysql -> unhandled data type column

Hello, We are using Kamailio 3.1.5 in production. We use the sqlops module to run a mysql function to return parameters. In the logs I am seeing the flowing warnings. /usr/sbin/kamailio[3991]: WARNING: db_mysql [km_res.c:143]: unhandled data type column (diallednumber) type id (6), use DB1_STRING as default /usr/sbin/kamailio[3991]: WARNING: db_mysql [km_res.c:143]: unhandled data type column (ringtime) type id (6), use DB1_STRING as default I think these are generated when we return a null value, although this is not causing us a problem can anyone advise how to eliminate these warnings.

OPTIONS Module

24 Nov '11

Hello, I have installed Kamailio 3.1.5 on Centos 5.5 using the kamailio-3.1.5-4.1.x86_64.rpm. I have a requirement that our Kamailio server supports SIP OPTIONS, looking through the module list it looks like the OPTIONS module is the way to go, unfortunately my install only includes the module and module_k Kamailio Modules. Is the only option to compile the OPTIONS module from source or is there a better way to configure Kamailio to respond to SIP OPTIONS?

Problem to relay sip message recieved port 9090 to asterisk port 7160
by arif tuhin 24 Nov '11

24 Nov '11

I'm Trying to relay sip messages from sip client to asterisk. Kamailio should accept the msg on 9090 udp port and it will forward the sip message to 7160 udp port of Asterisk. I thought the default cfg file will be enough to accomplish this simple task. But kamailio is receiving the msg ok but its not forwarding the msg. Another interesting thing is if i enable tls and give a tls port of kamailio , it easily forwards and the client registers ok. With Best Regards

(src_ip == 10.46.1.121 || src_ip == 10.46.1.122 )) { send_reply("403", "Forbidden"); exit; } Cheers, Daniel -- Daniel-Constantin Mierla -- http://www.asipto.com Kamailio Advanced Training, Dec 5-8, Berlin: http://asipto.com/u/kat http://linkedin.com/in/miconda -- http://twitter.com/miconda

Siremis v2.1.0 Released
by Elena-Ramona Modroiu 23 Nov '11

23 Nov '11

Siremis v2.1.0 has been released - this is an update to previous release v2.0.0, bringing several enhancements and new web pages to manage PUA and RLS. It is still compatible with Kamailio v3.1.x, the last of this kind, next one to be out in the near future will be compatible with Kamailio v3.2.x. You can find the news about this release, including links to download, screenshots and demos, at: * http://siremis.asipto.com/2011/11/23/siremis-v2-1-0-released/ Alternative download site (tarball or git pull) is from sourceforge project: * http://sourceforge.net/projects/siremis/ Regards, Ramona PS. Siremis v2.1.0 is working for most of the components with Kamailio 3.2.0, just the few that changed the database structure may not be fully functional (e.g., the modules with tables that have new columns, see http://www.kamailio.org/wiki/install/upgrade/3.1.x-to-3.2.0#sql_commands).

Hello, I plan to package v3.2.1 after mid of next week (most probably on Thursday) -- it is about 1 month and a half since 3.2.0 was released and branch 3.2 accumulated a bunch of patches. Anyone having comments about it?

Kamailio best performance
by Ricardo Martinez 23 Nov '11

23 Nov '11

Hello list. I’m having some issues with the Kamailio versión 3.2.0. I want to ask if someone could give some hints how to optimize the performance of my kamailio server. For some reason and from time to time the kamailio process start to answer slower than usual, making calls fail and register expires. I’m still unable to detect the problem, but I want to know of maybe i´m running my kamailio not under the best conditions.

Hello list. First of all sorry for dump question, i'm pretty new to kamailio so i hope someone point me in right direction currently i have one sip device which can handle sip request only from one ip, my goal is to put kamailio in front of it so i can proxy requests from several ips i added this to conf route{ if ( src_ip == 10.46.1.121 || src_ip == 10.46.1.122 ) { if(method == "INVITE") { $rd="10.46.29.10"; t_relay(); } } and calls seems connecting but signaling is completely broken i understand that i'm doing something wrong, but can't get what is wrong Please point me to solution Thanks

strange behavior when trying to reach PSTN gateway via TCP
by Dmitry Petrakoff 23 Nov '11

23 Nov '11

Hi List! I'm running Kamailio for about 1 year without any serious problems. When it works with UDP only, it runs perfectly well for us. Without any major issues. But now we have a customer who wants to connect Lync to our network. Unfortunately, Lync does not support UDP for SIP signalling, so we tried to teach kamailio to send SIP messages via TCP. And getting strange error: 10(36629) DEBUG: tm [t_reply.c:659]: DEBUG: reply sent out. buf=0x832c7ac: SIP/2.0 100 trying -..., shmem=0x28d97c7c: SIP/2.0 100 trying - 10(36629) DEBUG: tm [t_reply.c:669]: DEBUG: _reply_light: finished 10(36629) DEBUG: <core> [forward.c:213]: DEBUG: get_out_socket: socket determined: 0x833ddc0 10(36629) DEBUG: <core> [msg_translator.c:457]: clen_builder: content-length: 553 (553) 10(36629) DEBUG: <core> [msg_translator.c:204]: check_via_address(10.200.245.200, 10.200.245.200, 0) 10(36629) DEBUG: <core> [tcp_main.c:1824]: tcp_send: no open tcp connection found, opening new one 10(36629) DEBUG: <core> [ip_addr.c:247]: tcpconn_new: new tcp connection: 10.198.3.100 10(36629) DEBUG: <core> [tcp_main.c:1081]: tcpconn_new: on port 5060, type 2 10(36629) DEBUG: <core> [tcp_main.c:1382]: tcpconn_add: hashes: 0:0:0, 1 10(36629) ERROR: <core> [tcp_main.c:2748]: connect 10.198.3.100:5060 failed Socket is not connected 10(36629) ERROR: <core> [tcp_main.c:2754]: 10.198.3.100:5060: connect & send for 0x28d988ac failed: Socket is not connected (57) 10(36629) DEBUG: <core> [tcp_main.c:2955]: tcpconn_chld_put: destroying connection 0x28d988ac (1, -1) flags 0060 10(36629) ERROR: tm [../../forward.h:170]: msg_send: ERROR: tcp_send failed We tested two different variants: one when defined Lync in dr_gateways table as 10.198.3.100:5068;transport=tcp And then, tried global options udp_mtu=1300 udp_mtu_try_proto=TCP As soon as these options were enabled, all other gateways became unreachable with the same error as above.

LCR weight parameter
by Fabian Borot 22 Nov '11

22 Nov '11

Hello On kamailio 1.5.2, I need to choose the gw from a group according to its weight. After trying unsuccessfully with different values I realized that the help guide says that the load_gw functions can return gateways according to "gateway's randomized weight within its group". So, I have these questions: 1- since it is "randomized", does this mean that the weight parameter actually can not guarantee that the weight value can decide how gateways are ordered? 2- once I have the gws on the avp, is it posible to re-order them? if so, how? thank you very much fborot

Hi, During planned down time of Kamailio, I would like to send a Notice to all the users currently registered on the system. It would be nice if it appears in their Chat windows. I am thinking if I could loop through user_location table and send MESSAGE to individual user. What's the best way to accomplish this task? Thanks Krish Kura

How long (in bytes) is an AVP which reads an Integer from DB?

Hi, I need to read from a MySQL table a 32 bits long Integer column. My question is: how many bytes does Kamailio use for storing integer values fetched from a DB query? does it depend on the 32/64 bits architecture? Thanks a lot. -- Iñaki Baz Castillo <ibc(a)aliax.net>

GIT committing and backporting
by Daniel-Constantin Mierla 21 Nov '11

21 Nov '11

Hello, I put together a wiki page to help people porting patches between branches, exemplified with master and 3.2 branches -- the typical patch backporting these days: * http://www.kamailio.org/wiki/devel/backporting-to-3.2.x They are useful also for people with no write access, in case they want to try patches committed to devel branch in their local git repo clones. In additions, I added to kamailio wiki the page with guidelines for commits, trying to give the generic suggestions of how to do it in order to keep the coherence of the development: * http://www.kamailio.org/wiki/devel/git-commit-guidelines Updates and enhancements are welcome! If one has more suggestions or want to debate some of the proposed guidelines, feel free to start the discussion on the mailing list. Cheers, Daniel -- Daniel-Constantin Mierla -- http://www.asipto.com Kamailio Advanced Training, Dec 5-8, Berlin: http://asipto.com/u/kat http://linkedin.com/in/miconda -- http://twitter.com/miconda

Limiting simultaneous calls
by Mino Haluz 21 Nov '11

21 Nov '11

Hi, I was using cdrtool (prepaid table) and callcontrol to limit concurrent calls. In fact this is only limiting the outbound calls, but I would like to use another mechanism which should limit the inbound calls too. So basically to limit voice channels. So is there some reliable method/module how to achieve this? Thanks, Mino

Dropped registrar bindings with 1.5.3
by Alex Balashov 19 Nov '11

19 Nov '11

I have a 1.5.3 installation functioning as a registrar that is exhibiting a very curious, if only infrequent set of behaviours. The host is CentOS 5.x, with PostgreSQL 9.0 backing usrloc, and db_mode = 1 (immediate write-through). I have a registration handler in my initial request route that begins with a log message: ... else if(is_method("REGISTER")) { xlog("L_INFO", "... Processing REGISTER from $si:$sp for AOR $tu\n"); route(2); exit; } I've got a registrant who consistently re-registers with an expiration time of 120, so in theory they ought to be re-registering every two minutes or so. Most of the time they do. But, occasionally, I'll see a gap of 5-8 minutes go by, in which the above log message does not appear, and their registration expires so that they can't receive calls. That's not what's interesting. What's interesting is that I did a packet capture on the proxy and caught one of these scenarios. Within that ~8 minute window when the registration expired and calls were failing, the UAC actually re-registered several times, on normal ~2 minute boundaries, AND the proxy successfully challenged the request and sent a 200 OK indicating that the binding was stored! I double-checked all the parameters to ensure that the 401s and 200 OKs corresponded to the right REGISTER flow, etc. - yes, it's all correct. Is there any imaginable set of circumstances or a known bug that would cause Kamailio to successfully authenticate and affirm a registration request, while neither logging its receipt, nor, evidently, storing it to the database? I can envision a number of database failure modes that would account for the binding not actually being in the 'location' table, but that doesn't explain why the request wouldn't even be logged. That's what has me baffled.

[Kamailio-Users] Converting rtpproxy recorded .rtp file to .wav file
by Vikram Ragukumar 18 Nov '11

18 Nov '11

Hello, I used Kamailio+rtpproxy to record a session and rtpproxy outputs the following files long_file_name.a.rtp, long_file_name.a.rtcp, long_file_name.o.rtp, long_file_name.o.rtcp http://www.rtpproxy.org/wiki/RTPproxy/FAQ From the Rtpproxy FAQ above, i tried to extract the audio using rtpbreak and sox. rtpbreak -W -r long_file_name.a.rtp rtpbreak -W -r long_file_name.o.rtp The above commands generate rtp.0.0.raw, rtp.1.0.raw. Then when i run sox using sox --combine merge -r 8k -A rtp.0.0.raw -r 8k -A rtp.1.0.raw -t wavpcm -s out.wav i get the following errors : sox: invalid option -- - sox: -c must be given a number Is there a switch/anything else that i am missing ? Thanks in advance, Regards, Vikram.

Core compiled with Sctp support
by Stefan Ljung 18 Nov '11

18 Nov '11

I've downloaded sip-router 3.1.2 and have been struggling with the make commands for configuring. Compiling and installing. Can't really say that I master it. But I have finally managed to do all steps and started a example ser.cfg. One of the features I want to play around eith is the sctp transport. >From previous experiments with OpenSER I kearned that if I only specify a listen host address without transport protocol all three UDP TCP and SCTP sockets will be started. Ths time I only see UDP and TCP: Listening on udp: 127.0.0.1:5060 tcp: 127.0.0.1:5060 Aliases: tcp: localhost:5060 tcp: localhost.localdomain:5060 udp: localhost:5060 udp: localhost.localdomain:5060 I have read the c sources to verify that the sctp libs and header files are in the right places, and they are. What I could need is a tip on how to verify that my core has been compiled with sctp support. How can I see that ? In what files would there be a confimation of that the sctp feature will be compiled in? /Stefan

Problem trying to play recorded message before call
by David Candamil Santos 18 Nov '11

18 Nov '11

Hi there, guys. I hope you can help me. I use kamailio to comunicate some servers (each one with its own kamailio). When an user calls another, depending on the userID that will receive the call, the server redirects the call to the corresponding kamailio server. It works properly. Now, what I would like to do is to configure it so it plays a notification saying where the call is going to be forwarded. After reading some tutorials, I tried to get it working with rtpproxy, but after configuring it, it doesn't play the clips. I am testing it with a *.wav file. The path to the file is "/usr/local/etc/kamailio/test.wav" (it's in the kamailio directory). This is my software: Debian stable kernel 2.6.32-5-686 Kamailio 3.2.0 (GIT installation) rtpproxy 1.2.1-1 Kamailio and rtpproxy are running in the same machine. These are the log messages: -------------------kamailio.log------------------- (SEVERAL TIMES) Nov 16 12:58:10 debian-virtualbox kamailio[2076]: INFO: rtpproxy [rtpproxy.c:1415]: rtp proxy <udp:127.0.0.1:22222> found, support for it enabled (SEVERAL TIMES) Nov 16 12:58:12 debian-virtualbox kamailio[2069]: ERROR: <script>: Intentando reproducir audio -------------------------------------------------- This is the relevant configuration: --------------/etc/default/rtpproxy--------------- # The control socket. #CONTROL_SOCK="unix:/var/run/rtpproxy/rtpproxy.sock" # To listen on an UDP socket, uncomment this line: CONTROL_SOCK=udp:127.0.0.1:22222 # Additional options that are passed to the daemon.

mtree on db Berkeley DB?
by Javier Gallart 16 Nov '11

16 Nov '11

Hi list we've been happily using the mtree module for months now. Lately the size of the tree has grown a lot. The mtree table needs to be fully repopulated and reloaded several times a day, and we are looking for a fastest mechanism (for populating the table, I guess the reload time does not depend much on the db backend...). Does anyone tried with Berkeley DB? Is this combination mtree-berkeley actually feasible...? Thanks Javi

Hello, I am trying to install the tls module in 3.2.0. I run apt-get update before apt-get install kamailio-tls-modules and still can't load the tls module and getting the following error. Kamailio can't find the tls module even though it's installed? I didn't get any errors when I run apt-get install kamailio-tls-modules. Everything else is defined in the config file.

Hello, I think the problem was a comma at the end of sipcapture module name in kstandard group inside the Makefile. If you pull the branch 3.2, it should get the fix. The master was fixed by Ovidiu Sas few minutes ago when adding xhttp_rpc module in that list. Let us know if works now.

Problem with NAT and RTPProxy
by David Candamil Santos 14 Nov '11

14 Nov '11

Hi, I am using Kamailio 3.2.0 (x86_64/linux) and since some days ago I am trying to call from a network with NAT to outside. This is the configuration: Softphone (192.168.0.5) <--> Kamailio (192.168.0.3) <--> Router (192.168.0.1) <--> Softphone over smartphone All the router ports are opened and redirected to 192.168.0.3. I have installed rtpproxy 1.2.1-1 with the following configuration: --------------------------/etc/defaults/rtpproxy-------------------------------- # The control socket. #CONTROL_SOCK="unix:/var/run/rtpproxy/rtpproxy.sock" # To listen on an UDP socket, uncomment this line: CONTROL_SOCK=udp:127.0.0.1:22222 # Additional options that are passed to the daemon. EXTRA_OPTS="-l candamil.dyndns.org" ---------------------------------------------------------------------------------------- and works properly. This is the log message: ---------------------------------------------------------------------------------------------- Nov 12 20:09:13 condor kamailio[7001]: INFO: rtpproxy [rtpproxy.c:1415]: rtp proxy <udp:127.0.0.1:22222> found, support for it enabled ----------------------------------------------------------------------------------------------- Both softphones are "linphone". The configuration of the network softphone is the following: SIP identity: sip:1001@192.168.0.3 SIP proxy: sip:192.168.0.3 Direct connection to the Internet. In the softphone of the smartphone I set as proxy and domain " candamil.dyndns.org", the DNS address of my router IP. In this case, these are the symptoms: Both softphones can autentify correctly. When calling, both softphones ring, but when I answer, the voice signal is not received. This is the log error: ---------------------------------------------------------------------------------------------- Nov 12 20:23:14 condor kamailio[6991]: ERROR: rtpproxy [rtpproxy.c:2260]: incorrect port 0 in reply from rtp proxy ---------------------------------------------------------------------------------------------- The same happens if I set in the network softphone that it's behind NAT, and I set the router IP. The same happens if I set in the network softphone that it's behind NAT and with a STUN server (stunserver.org). In the three cases, in the softphone over smartphone, the caller is 1001(a)192.168.0.3, and in the network softphone, the caller is 1002(a)candamil.dyndns.org. If I set in the network softphone the proxy as sip:candamil.dyndns.org, the same happens. If what I do is setting the SIP identity as sip:1001@candamil.dyndns.org, when calling form inside to ouside the network, the softphone doesn't know that the call was answered, and there is the following error in the log: ---------------------------------------------------------------------------------------------------------- Nov 12 20:53:00 condor kamailio[7306]: ERROR: <core> [parser/parse_via.c:2600]: ERROR: parse_via: invalid port number <5060ranch=z9hG4bKc 50f.b4825246.0> Nov 12 20:53:00 condor kamailio[7306]: ERROR: <core> [parser/parse_via.c:2629]: ERROR: parse_via on: <SIP/2.0/UDP 192.168.0.3:5060ranch=z 9hG4bKc50f.b4825246.0;received=87.223.138.84#015#012Via: SIP/2.0/UDP 87.223.138.84:5060;rport=5060;branch=z9hG4bK1021772993#015#012From: <sip:1001@candamil.dyndns.org>;tag=783852345#015#012To: < sip:1002@candamil.dyndns.org>#015#012Call-ID: 1644787160#015#012CSeq: 21 INVITE# 015#012User-Agent: Linphone/3.4.0 (eXosip2/unknown)#015#012Content-Length: 0#015#012#015#012> ------------------------------------------------------------------------------------------------------------ If the call is from outside to inside the network, it happens the same than in the previous cases.

SnmpStats problem
by Adam Kuśmirek 14 Nov '11

14 Nov '11

Hi All I've compiled kamailio 3.2.0 with snmpstats module. When trying to start the module I received the following message: 0(28197) DEBUG: <core> [sr_module.c:515]: load_module: trying to load </usr/lib/kamailio/modules_k/ snmpstats.so> 0(28197) ERROR: <core> [sr_module.c:523]: ERROR: load_module: could not open module </usr/lib/kamailio/modules_k/snmpstats.so>: /usr/lib/libnetsnmpagent.so.10: undefined symbol: boot_DynaLoader I run it on CentOS 5.7 After digging Internet, I found the solution for the problem. I had to modify Makefile in snmpstats module's directory and recompile it. I had to change BUILDAGENTLIBS env param before change: BUILDAGENTLIBS =-L$(LOCALBASE)/lib -lnetsnmpmibs -lnetsnmpagent \ -lnetsnmphelpers -lnetsnmp after change: BUILDAGENTLIBS =-L$(LOCALBASE)/lib -lnetsnmpmibs -lnetsnmpagent \ -lnetsnmphelpers -lnetsnmp \ -Wl,-E -Wl,-rpath,/usr/lib/perl5/5.8.8/i386-linux-thread-multi/CORE \ -L/usr/local/lib /usr/lib/perl5/5.8.8/i386-linux-thread-multi/auto/DynaLoader/DynaLoader.a \ -L/usr/lib/perl5/5.8.8/i386-linux-thread-multi/CORE \ -lperl -lresolv -lnsl -ldl -lm -lcrypt -lutil -lpthread -lc \ -lwrap \ -lsensors \ -lrpmdb -lrpm After that I successfully started snmpstats module. I don't know why I didn't have compilation errors before adding this linking info, but got problem when trying to run compiled module. Can you explain it ? Do you know another way to solve the problem ? Regards Adam

tracking ACC for a 486
by Sven Knoblich 10 Nov '11

10 Nov '11

Hi, I have a short question regarding a tm callback. I want to track a local generated ACK during a cfa. scenario: A calls B with a cfa to C B response with a 486 Busy this will be confirmed with an ACK. I saw, that TMCB_ACK_NEG_IN will only be called when a new transaction is created (t_lookup.c:t_newtran). Unfortunately in this case an ACK will be send directly when a reply will be received (t_reply.c:reply_received). Any ideas? thanks in advance, Sven

Hi All, Kamailio 3.1.2 terminated with signal 11, segmentation fault, in the init_mod_child function at sr_module.c file.

How to limit number of calls in Kamailio proxy
by Austin Einter 10 Nov '11

10 Nov '11

This is continuation with limiting number of calls per Kamailio proxy server. I modified kamailio.cfg as below. 1. loadmodule "dialog.so" 2. modparam("dialog", "enable_stats", 1) 3. modparam("dialog", "dlg_flag", 4) Next, as dialog module I can use either active_dialogs() or $DLG_count to find number of calls present at any given point of time. However if I use active_dialogs() I get parse error when I run kamailio proxy. Next I used $DLG_count , but always I am getting value of $DLG_count as 0. In *route* section, I added code as below. if (is_method("INVITE")) { if($DLG_count > 1) { sl_send_reply("503","RESOURCE UNAVAILABLE"); exit; } else { xlog("Dialog count = $DLG_count\n"); } } Everytime a new call starts , it prints $DLG_count as 0. Kindly let me know whats going wrong here. Regards Austin

uacreg issue
by Lucas Alvarez 09 Nov '11

09 Nov '11

Hi, after following the steps of this guide: http://by-miconda.blogspot.com/2010/10/best-of-new-in-kamailio-310-10.html, poulating the uacreg table, loading the uac module and restarting kamailio I didn't see any REGISTER packet sent out to the sip provider, is something missing? How can I know if the values from the table are being loaded? I would appreciate any kind of help. Regards, Lucas Alvarez

negative www_authorize result codes
by Juha Heinanen 09 Nov '11

09 Nov '11

auth_db/README tells this about www_authorize() negative result codes: Negative codes may be interpreted as follows: * -1 (generic error) - some generic error occurred and no reply was sent out; * -2 (invalid password) - valid user, but wrong password; * -3 (invalid user) - authentication user does not exist. whereas in auth_radius i return: Negative result codes may be interpreted as follows: * -7 (internal error) - some internal error occurred (see syslog); * -6 (nonce reused) - nonce is used more than once; * -5 (no credentials) - credentials were not found in request; * -4 (stale nonce) - stale nonce; * -3 (authorization failed) - RADIUS responded with Access Reject which may be, for example, due to user not found or wrong password; * -1 (error) - some error occured during authorization (see syslog); since both modules depend on the same auth module, why does www_authorize return the full set of negative result codes or is its README out of date? -- juha

Conditional uacreg
by Alex Balashov 08 Nov '11

08 Nov '11

Is there some way by which credentials can be loaded into the uacreg table, but not all of them used at once? The problem I have is a need to make these registrations active and inactive periodically, whereas the registration facility that the uac module provides is fully managed/largely unattended. Using $uac_req(...) is not an option because I need to capture the failure replies (which is not supported in TM) in order to do digest challenge authentication. -- Alex Balashov - Principal Evariste Systems LLC 260 Peachtree Street NW Suite 2200 Atlanta, GA 30303 Tel: +1-678-954-0670 Fax: +1-404-961-1892 Web: http://www.evaristesys.com/

This is bullshit. People seem to not understand IP at all. rtpproxy is forwarding in user mode - it receives on a UDP socket and sends on a UDP socket. Thus, kernel based forwarding is not involved when using rtpproxy. You can disable IP forwarding again. > #echo "1" >> /proc/sys/net/ipv4/ip_forward > #sysctl -p > > > Here are the corresponding Logs from Kamailio and rtpproxy. The thing is quite easy. Swap the IP addresses when starting rtpproxy and then configure Kamailio to call rtpproxy with the proper i,e flags (as described in my previous email). For example: if (has_body("application/sdp")) { if ($si == "192.168.2.75") { # message from internal to external rtpproxy_manage("ie"); } else { # message from external to internal rtpproxy_manage("ei"); } } Put above code block in the main route block and also in a reply route which will be activated (or in the default reply route). Put some xlog statements around the rtpproxy calls to verify the proper command is called. regards Klaus

CANCEL is not forwarded, if callee does not respond
by Mino Haluz 04 Nov '11

04 Nov '11

Hi, the scenario is like this: - user1 makes a call to user2 - proxy sends receives INVITE and sends it to user2 - user2 does not respond at all (firewall for example) - user1 after 5 seconds hangs up the call with CANCEL - proxy sends to user1 200 canceling CANCEL is not forwarded to user2. Ok this behaviour is maybe ok, but after 30 seconds Request timed out is sent to user1 (fr_inv_timer possibly hit). So if I am thinking well, first CANCEL did not match the transaction ? Why ? It this behaviour ok or do I have to search for something wrong in the config? Thanks, Mino

Hello List, I've successfully configured Kamailio with a farm of asterisk servers in L/B | F/O mode. The topology is something like below: User<-->Kamailio<-->Asterisk-Servers Both kamailio and Asterisk serevrs are on public IPs *The problem:* Kamailio and Asterisk Servers need to be on Public IPs in order to fully handle NAT/media related issues. Whereas what I require is to have two interfaces at kamailio server, one is Public other is Private and All the Asterisk Servers should be on LAN/Private IPs. I've tried making a scenario as per my requirement (attached image) but there are some serious NAT and media issues. Can anyone help me how to handle NAT'd Asterisk servers behind Kamailio?

Dispatcher Confusion (v3.2.0)
by Asgaroth 03 Nov '11

03 Nov '11

Hi All, Just been doing some testing with Kamailio 3.2 and the dispatcher module, and have some strange behaviour, can we confirm if it is expected behaviour or a bug of some sort. It appears that I can only set the dspatcher state via fifo command once, and not reset it again, here is an example: version: kamailio 3.2.0 (i386/linux) 94d3b8 flags: STATS: Off, USE_IPV6, USE_TCP, USE_TLS, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, DBG_QM_MALLOC, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 4MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: 94d3b8 compiled on 12:34:43 Oct 20 2011 with gcc 4.1.2 Here we start with the dispatcher list as it was pulled from the database and currently loaded in memory. # kamctl dispatcher dump SET_NO:: 2 SET:: 1 URI:: sip:1.1.1.1:10001 flags=AX priority=0 attrs= URI:: sip:1.1.1.1:10000 flags=AX priority=0 attrs= SET:: 2 URI:: sip:1.1.1.1:10003 flags=AX priority=0 attrs= URI:: sip:1.1.1.1:10002 flags=AX priority=0 attrs= Now I try to set one gateway inactive: # kamctl fifo ds_set_state i 1 sip:1.1.1.1:10001 # kamctl dispatcher dump SET_NO:: 2 SET:: 1 URI:: sip:1.1.1.1:10001 flags=IX priority=0 attrs= URI:: sip:1.1.1.1:10000 flags=AX priority=0 attrs= SET:: 2 URI:: sip:1.1.1.1:10003 flags=AX priority=0 attrs= URI:: sip:1.1.1.1:10002 flags=AX priority=0 attrs= All normal so far, now if I try to set the same gateway active again, the state still stays inactive, i dont seem to be able to change the state back to active. The same thing happens if I attempt to set this state to disabled and then try to set it back to active afterwards. The state does not change from what the first attempt was. # kamctl fifo ds_set_state a 1 sip:1.1.1.1:10001 # kamctl dispatcher dump SET_NO:: 2 SET:: 1 URI:: sip:1.1.1.1:10001 flags=IX priority=0 attrs= URI:: sip:1.1.1.1:10000 flags=AX priority=0 attrs= SET:: 2 URI:: sip:1.1.1.1:10003 flags=AX priority=0 attrs= URI:: sip:1.1.1.1:10002 flags=AX priority=0 attrs= Now I can try to set the state to inactive probing, that works. # kamctl fifo ds_set_state ip 1 sip:1.1.1.1:10001 # kamctl dispatcher dump SET_NO:: 2 SET:: 1 URI:: sip:1.1.1.1:10001 flags=IP priority=0 attrs= URI:: sip:1.1.1.1:10000 flags=AX priority=0 attrs= SET:: 2 URI:: sip:1.1.1.1:10003 flags=AX priority=0 attrs= URI:: sip:1.1.1.1:10002 flags=AX priority=0 attrs= Now if I try to disable the same destination: # kamctl fifo ds_set_state d 1 sip:1.1.1.1:10001 # kamctl dispatcher dump SET_NO:: 2 SET:: 1 URI:: sip:1.1.1.1:10001 flags=IP priority=0 attrs= URI:: sip:1.1.1.1:10000 flags=AX priority=0 attrs= SET:: 2 URI:: sip:1.1.1.1:10003 flags=AX priority=0 attrs= URI:: sip:1.1.1.1:10002 flags=AX priority=0 attrs= State still stays in Inactive/Probing mode. Now if I try to set the same gateway to active/probing mode, I cant: # kamctl fifo ds_set_state ap 1 sip:1.1.1.1:10001 # kamctl dispatcher dump SET_NO:: 2 SET:: 1 URI:: sip:1.1.1.1:10001 flags=IP priority=0 attrs= URI:: sip:1.1.1.1:10000 flags=AX priority=0 attrs= SET:: 2 URI:: sip:1.1.1.1:10003 flags=AX priority=0 attrs= URI:: sip:1.1.1.1:10002 flags=AX priority=0 attrs= The only way for me to get the state back to active after the above is to do a reload on the dispatch table: # kamctl dispatcher reload # kamctl dispatcher dump SET_NO:: 2 SET:: 1 URI:: sip:1.1.1.1:10001 flags=AX priority=0 attrs= URI:: sip:1.1.1.1:10000 flags=AX priority=0 attrs= SET:: 2 URI:: sip:1.1.1.1:10003 flags=AX priority=0 attrs= URI:: sip:1.1.1.1:10002 flags=AX priority=0 attrs= Is the dispatcher expected to behave as above? I'm still trying to understand the different states assuming the following options are set in the configuration file: modparam("dispatcher", "ds_ping_interval", 10) modparam("dispatcher", "ds_probing_threshhold", 1) modparam("dispatcher", "ds_probing_mode", 0) AX = Active/No Probing (*) Gateway is used in ds_select_*, ds_next_* (*) No OPTIONS/INFO messages are sent to destination to check alive state This appears to be the normal operating state with no issues detected. AP = Active/Probing (*) Gateway is NOT used in ds_select_*, ds_next_* (*) OPTIONS/INFO messages ARE sent to destination to check alive state This appears to be the state taken when a gateway times out and ds_mark_dst("p") is set in failure route, the gateway is "pinged" while down and set into AX mode once a response is recieved. IX = Inactive/No Probing (*) Gateway is NOT used in ds_select_*, ds_next_* (*) No OPTIONS/INFO messages sent to destination This appears to be the state taken when a gateway times out and if ds_mark_dst("i") is set in failure route, this gateway is set inactive and no "pinging" is performed. IP = Inactive/Probing (*) Gateway is NOT used in ds_select_*, ds_next_* (*) OPTIONS/INFO messages ARE sent to destination I'm not sure when this state would be reached unless it is set by fifo command. The ds_mark_dst function only allows "a","i" or "p". So the probing method would only become active is ds_probing_mode = 1. In my case it is 0, so I'm not sure if I would ever reach this state unless I forced it. What would happen here is the gateway came back alive once in "IP" state, would it go back to "AX" state? DX = Disabled/No Probing (*) Gateway is administratively set to down This is where manual intervention has occured and the destination has been set to administrativly down, for example, work being carried out on the destination gateway. All these states make sense, for the most part, I'm a little unsure of how IP/IX is meant to work unless you manually set it to "inactive" in your failure route. The main concern though is the the fifo commands dont appear to be working as expected, I can only set the state for a destination manually once, and not again after that, unless I perform a dispatcher reload. Has anyone else experienced this behaviour? Any comments/suggestions explanations are most welcome. Thanks

Kamailio dinner next week in Cape Town, South Africa
by Daniel-Constantin Mierla 03 Nov '11

03 Nov '11

Hello, it happens to come across Cape Town for few days and I was wondering if there are folks using our project or doing VoIP in general that want to meet up for a dinner. The date for dinner is planned for next Tuesday, November 8, 2011. Place will be decided once I know if there are people coming and how many. Likewise with such events done in the past, it is going to be a dinner open for everyone that wants to join, each participant paying the drinks and food for himelf/herself. The goal is to meet and discuss latest trends in IP communication and what's up lately around our project. Here are some pictures from two past similar events: http://www.asipto.com/gallery/v/social_meeting_barcelona2008/ http://www.asipto.com/gallery/v/FOSDEM2009/ So, if there are people on these mailing lists in the area of Cape Town next Tuesday and want to meet, please reply to me till Friday evening -- I will follow up privately to each person that is going to join with details about location and start time. Looking forward to meet some of you very soon! Cheers, Daniel -- Daniel-Constantin Mierla -- http://www.asipto.com Kamailio Advanced Training, Dec 5-8, Berlin: http://asipto.com/u/kat http://linkedin.com/in/miconda -- http://twitter.com/miconda

Dialog / BYE
by Brandon Armstead 02 Nov '11

02 Nov '11

Hello, I am attempting to tear down a call with a BYE packet generated externally (kind of similar to Kamailio fifo dlg_end_dlg). Let me describe what I am trying to do in more depth and then I will continue to tell you the problem I think I am experiencing. [PSTN SIP Proxy] -> [CORE SIP Proxy] -> [REGISTRAR] -> [UAC] So the above layout is the normal call flow / structure of calls (incoming when originating from pstn) (outgoing when originating from uac). I then have an "external" host - I am attempting to generate a BYE to [CORE SIP Proxy] and have it go both directions [PSTN] + [UAC]. So far I am able to get the call to tear down in only a single direction (only kill call with PSTN) or (only kill call with UAC). I have not been able to kill both legs of the call. I have tried sending a single BYE and using some dlg_bye("all") magic. - does not work, only kills one leg of the call. I have tried sending a BYE message to SIP Proxy for each leg (two BYE). - does not work, only kills one leg of the call. If I alternate the later method's BYE packet and only send A or B and not both Leg A or B will be killed... I think I am running into a race condition where the dialog is destroyed before the 2nd BYE packet is processed. My Question - what am I doing wrong - or what is the best method to tackle this task? Thank you for all of your help and time in advance. Sincerely, Brandon Armstead

Siremis: cannot enter domain in "New Subscriber" window
by Uwe Andersen 02 Nov '11

02 Nov '11

Hi, I want to add a new user. So I choose "add" from the "Subscriber Management" page. On the "New Subscriber" page I can enter username, password, email-address, etc. But the line for "domain" seems to be an empty dropdown entry. I cannot choose, add or edit anything. As a result I cannot save the new user because Siremis complains about the empty domain field. After adding a user by command line("kamctl add ...") the user appears on the management page. If I edit that user via Siremis the line for domain is not a dropdown but a "normal" text field. Can somebody explain this? BR, Uwe P.S.: I'm using Siremis 2.0 and Kamailio 3.2.0.

02 Nov '11

Hi, I am a new user of Kamailio, and I am working on enabling the App_Python module in Kamailio.. While searching on google, I came acroos your email on the forum where you people are trying to patch the App_Python module.. I am wandering whether you can please help a bit .. 1- How to do the configuration to enable the App_python module ? .. At the moment, I am just adding the following line in the configuration file, loadmodule "app_python.so" and just correcting the path to handler.py to the right directory in the code for script path. 2- What output we should expect when we enable the app_python module ? .. I have seen the handler.py script written in python which is printing some sip message information ? .. 3- How the SIP Message structure is being passed to handler.py ? ... How we are accessing the Router module in handler.py script and LM_ERR function from Kamailio ? .. Any help in this regards shall be really helpful .. In any case, whether you can solve this issue or not, please reply the email.. With many thanks.. Kind Regards, Nasir

enabling app_python module in Kamailio
by Muhammad Nasir Bhutta 01 Nov '11

01 Nov '11

Hi, I am trying to enable the app_python module in Kamailio to run a simple python script externally parallel with Kamailio proxy, While I try to load the module "app_python.so" in configuration file, the Kamailio server fails to start.. I can't see what is the problem .. The steps, I am following are that: - Script written in python saved in home directory. - Loadmodule "app_python.so" statement in configuration file. - Modparam("app_python", "script_name", "location of script") - Python_exec("function", "parameters list") .. I have also tried to check the Kamailio configuration option, It gives following warning, 0(2942) WARNING: <core> [sr_module.c:584]: /usr/local/lib64/kamailio/modules/app_python.so: exports dlflags interface is deprecated and it will not be supported in newer versions; consider using mod_register() instead I am wandering if any one can please help in this matter, I shall be very thankful ..

by Muhammad Nasir Bhutta 01 Nov '11

01 Nov '11

Hi, I have successfully installed the app_python module for the default example of handler.py .. Now, I need to see the output of handler.py,.. I have following questions: 1- What is the output of this module ? does it prints the specific message information extracted from SIP message ? 2- How to write modparam and python_exec in configuration file ? I have tried to write modparam("app_python", "mod_init") but, it gives error and says to use mod_register function instead and I don't know more about mod_register function. 3- I have also tried to use python_exec("child_init", 2) , The Kamailio starts successfully.. When, I connect a soft client to Kamailio, then nothing happens ? How to see the output of handler.py script . Any help in this regards shall be really appreciated .. With thanks.

Hi, I am a new user of Kamailio, and I am working on enabling the App_Python module in Kamailio.. While searching on google, I came acroos your email on the forum where you people are trying to patch the App_Python module.. I am wandering whether you can please help a bit .. 1- How to do the configuration to enable the App_python module ? .. At the moment, I am just adding the following line in the configuration file, loadmodule "app_python.so" and just correcting the path to handler.py to the right directory in the code for script path. 2- What output we should expect when we enable the app_python module ? .. I have seen the handler.py script written in python which is printing some sip message information ? .. 3- How the SIP Message structure is being passed to handler.py ? ... How we are accessing the Router module in handler.py script and LM_ERR function from Kamailio ? .. Any help in this regards shall be really helpful .. In any case, whether you can solve this issue or not, please reply the email.. With many thanks..

Hi, I did not understand the explanation of the use of flags and mask. I understand flags are for matching and mask is doing something. But, what exactly does the mask do? How do i see or use it? And regarding the flags... i did "setflag(16)" before the CR function. Set the DB col as needed, and no match was found... Any help here?

Memory Leak on DB Errors?
by Klaus Darilion 31 Oct '11

31 Oct '11

Hi! I recently had a problem with Kamailio 3.1.4 (provided Debian packages): I had some DB problems (missing tables). Thus, the timer module failed to insert the statistics (for siremis): ERROR: db_mysql [km_dbase.c:120]: driver error on query: Table 'kamailio.statistics_tmx' doesn't exist ERROR: <core> [db_query.c:130]: error while submitting query ERROR: sqlops [sql_api.c:217]: cannot do the query This happened for some time (weeks?), other DB queries were unaffected. Then, suddenly Kamailio ran out of memory: ERROR: <core> [sip_msg_clone.c:506]: ERROR: sip_msg_cloner: cannot allocate memory ERROR: tm [t_lookup.c:1338]: ERROR: new_t: out of mem: ERROR: tm [t_lookup.c:1478]: ERROR: t_newtran: new_t failed ERROR: sl [sl_funcs.c:282]: ERROR: sl_reply_error used: I'm terribly sorry, server error occurred (1/SL) It do not think it is a load problem as the server is more or less idle. May it be a memory leak due to wrong error handling? Where there any fixes recently? Thanks Klaus

Fwd: [RAI] SIPit 29 Summary
by Klaus Darilion 28 Oct '11

28 Oct '11

FYI -------- Original Message -------- Subject: [RAI] SIPit 29 Summary Date: Fri, 28 Oct 2011 09:40:51 +0200 From: Robert Sparks <rjsparks(a)nostrum.com> To: rai(a)ietf.org (also available at https://www.sipit.net/SIPit29_summary) SIPit 29 was hosted by Etsi Plugtests in Monte Carlo, Monaco the week of October 24-27, 2011. There were 34 attendees from 17 companies visiting from 12 countries. We had 25 distinct implementations. The roles represented (some implementations act in more than one role) 20 endpoints 5 proxy/registrars The b2buas attending this event were not attempting to appear to be proxies. Implementations using each transport for SIP messages: UDP 92% TCP 96% TLS 88% (24% server-auth-only) SCTP 8% DTLS 0% 44% of the implementations present supported IPv6. There were three RFC4474 Identity implementations present. For DNS we had support for: Full RFC3263 : 76% SRV only : 16% A records only : 08% no DNS support : 0% Support for various items in the endpoints: 75% replaces 50% ice 40% 5389stun 35% turn 25% sip/stun multiplexing 30% gruu 25% history-info (there were no implementations of 4244bis) 20% outbound 20% path 20% diversion 15% 3489stun 10% join 5% service-route 0% sigcomp Support for various items in the proxy/registrars: 100% path 80% sip/stun multiplexing 60% gruu 40% outbound 40% diversion 20% service-route 0% history-info The endpoints and b2buas implemented these methods: 100% INVITE, CANCEL, ACK, BYE 95% REFER 95% NOTIFY 80% REGISTER 80% INFO 75% OPTIONS 75% UPDATE 75% PRACK 60% SUBSCRIBE 35% MESSAGE 30% PUBLISH 100% of the implementations sent RTP from the port advertised for reception (symmetric-rtp). 30% of the implementations required the other party to use symmetric-rtp. 90% of the UAs present both sent RTCP and paid attention to RTCP they received. 80% of the endpoints present supported SRTP using sdes. There were no dtls-srtp implementations at this SIPit. 35% of the endpoints supported multipart/MIME. There were no implementations present with S/MIME support. 36% of the implementations present followed RFC6026 (corrections to the INVITE transaction) 36% followed RFC4320 (corrections to the non-INVITE transaction) Not counting implementations that support events only for REFER: There were 3 SIP Event Server implementations There were 5 SIP Event Client implementations These event packages were supported: Server Client 1 2 presence 1 1 presence.winfo 1 4 message-summary 1 1 dialog 1 1 reg 1 1 conference 1 1 xcap-diff 0 2 kpml These packages were supported with the eventlist extension: Server Client 0 1 presence Two of the proxies present still rely only on max-forwards and one that implemented 3261 loop detection. There were two implementations of fork-loop-fix, but no implementations of max-breadth. Multiparty tests (Notes provided by several test participants, including Eoin McLeod, Trond Andersen, Olle Johansson, and Adrian Georgescu) ** IPv6 Focused Tests The first multiparty session of the event focused specifically on IPv6. We used a basic forking scenario with endpoints registered with several proxies at the bottom of the tree. We had a mix of single and dual-stack endpoints, many supporting video. None of the participant's code would put both v4 and v6 candidates into ICE. Rather, it made assumptions about which candidates to use based on what was happening with the SIP signaling. We ran tests using SRV configurations stating that v6 should be tried first and v4 tried if the v6 failed (and a second configuration that tested v4 first) to ensure that implementations would fail forward and try both address families, with mixed results. We confirmed that one UA configured to use IPv6 only was able to request and use an IPv4 turn allocation and succeeded in making a call between an IPv4 UA and IPv6 ua. Most UAs that supported dual-stack had a configuration to tell the application to ignore any returned AAAAs due to issues encountered in deployments where endpoints autoconfigured IPV6 that didn't actually work. We successfully tested calls going though a mix of v4 and v6 hops (accruing Via and Route/Record-Route headers with addresses in both families. There was an instance of UA registering using sip-outbound (RFC5626) that used IPv4 and IPv6 flows simultaneously. We set up automated tests of using SRV records to indicate preference for IPv4 or IPv6. Two ipv4 only clients proved that they connect to a domain indicating preference for IPv6. ** Forking There are still UAs that do not sensibly handle multiple 200 OKs to a forked INVITE. When testing handling multiple 200 OKs on a simple two branch fork, we encountered an interesting failure. As the proxy handled the 200 OK from branch 1, it sent a CANCEL to the other branch. The UA on branch 2 had already responded with a 200 OK, so it responded to the CANCEL with a 200, but rather than ignoring it, it decided to send a BYE on the dialog. This surprised the calling UA which had chosen the 200 OK from branch 2 to keep, having already sent a BYE to the dialog from branch 1. The better thing for the UA to have done is ignore the CANCEL after replying to it. ** TLS Most of the implementations at the event supported TLS, and all the multiparty tests exercised it. One session focused on proper certificate verification. We tested a certificate at a server with several SAN URI fields, none of which matched the URI used for the server, but a CN that did. Only one UA failed to connect because of this, the rest of the UAs connected happily (or not at all, but because of other issues). Most of the implementations were "before 5922" code, which meant that there was a lot of checking of the Subject/CN. ** Identity There were several SIP Identity implementations present. We tested creating and verifying the Identity assertions at proxies. It wasn't immediately obvious to some implementers that the resource pointed to by the Identity-Info URI had to be DER encoded (a result of the requirement to use application/pkix-cert). Unfortunately, the tar encoded at the end of 4474 has .cer files in it that are PEM encoded. ** STUN/TURN/ICE and Outbound We spent a significant fraction of the multiparty test time (three sessions) focusing on STUN/TURN/ICE and Outbound. There are still clients using RFC 3489 STUN. The participants noted operator pushback against deploying ICE because when things go wrong, it's very hard to diagnose when, where and why they went wrong. If the endpoints always sent a reINVITE (or UPDATE) when concluding ICE, even if they used the default candidates, this diagnosis of failures would be much easier. Examples noted by the participants: * Without a mandatory conclusion, is not possible to know how long it took until end-points had successful media path established * Without a mandatory conclusion, is not always possible to know if different than default candidates have been chosen as lack of INVITE does not tell deterministically what happened * Without a mandatory conclusion, it is not possible for the callee to restart ICE if it does not agree with the conclusion We successfully exercised endpoints setting up and managing multiple outbound flows through separate edge proxies to a proxy/registrar (with different implementations taking turns in the proxy registrar role). We forced the network to break the flow in use in each case, verifying that subsequent dialog-forming requests would take an alternate flow. We discovered an issue with the recommendation in 5626 to have edge proxies record-route that prevents subsequent in-dialog requests from using alternate flows. ** SRTP All implementations supported SDES for SRTP key exchange. Good interop with many different combinations of endpoints. Some calls were left up for an extended period so that sequence number wrapping and roc increments were tested. Once the roc had changed the call was put on hold and resumed with success. In this situation new RTP streams with different SSRCs were created and the sequence number/roc combination re-generated thus proving that support for multiple SRTP contexts exists. Debate surrounding how to signal 'best-effort crypto' continues. Some implementations choose to advertise RTP/AVP with a=crypto attributes and then go crypto if answer also has them and non-crypto if they do not. RTP/SAVP is used to signal the desire for mandatory crypto. Another approach observed was to repeat the same media line twice, once for crypto and once for non-crypto and rely on the receiving end to only accept one of them and port reject the other. In this case both m-lines had the same port number and payload number descriptions so if a receiving end accepted both then the originator would have no clue as to whether it was receiving crypto or non-crypto traffic. ** Unusual messages We tried several kinds of valid, but unusual messages. Very few implementations did the right thing with a request-URI with an unknown scheme - some phones would answer an INVITE with that in the request-URI. ** Specification questions / comments RFC 3263 currently says "If no SRV records are found, the client SHOULD use TCP for a SIPS URI" - it should probably say TLS over TCP. In the spirit of Happy Eyeballs, there should be some guidance on what to do when the RFC 3263 process results in both A and AAAA records and the client is capable of using both. There were implementations of SIP over DTLS, but the specification of that usage seems not to have completed. There were questions on whether internationalized domain names could be used in SIP URIs. For use of SDP with ICE, there was an argument about whether a=rtcp was mandatory if rtcp was on the next port up. RFC 5245 says "If the agent is utilizing RTCP, it MUST encode the RTCP candidate using the a=rtcp attribute as defined in RFC 3605 [RFC3605].", and 3605 says "when that port is not the next higher (odd) port number following the RTP port described in the media line" to motivate why the attribute was created to begin with. Any updates to 5245 should clarify that adding the a=rtcp attribute is not optional when RTCP is being sent on the next higher port. _______________________________________________ RAI mailing list RAI(a)ietf.org https://www.ietf.org/mailman/listinfo/rai

How to limit maximum number of calls
by Austin Einter 28 Oct '11

Hi I am running kamailio proxy (1.5) as an intermediate proxy, where all my SIP signalling packets are passing through. I want to limit maximum number of calls kamailio proxy server can handle at a time. How can I do this, please give me some pointer in this regard. Regards Austin

sip-router listen address
by caio 25 Oct '11

25 Oct '11

Hello, Is there a problem or anything to consider when sharing the same ip/interface between sip proxy and asterisk? I have asterisk on port 5080 and SR at 5060 in the same interface with the same IP address and have a missing BYE when call is over. However, moving asterisk service to different interface and ip in the same box, the issue is solved. I appreciate your comments. Regards, Claudio

Kamailio.cfg file woes
by Peter Schrock 24 Oct '11

24 Oct '11

I am wondering two things. 1. is there a place on the web that I may find a basic cfg file to at least get Kamailio running. 2. is there a resource that tells you what to include for what you want to use the system for. At this point, it seems like I should just include everything because I don't know what I might not need. I looked at the references on the website and found the information a little overwhelming with all the options that are available. I think smaller bit sizes would be helpful at this time for me.

Hi All, Does the onsend route get executed for all messages? I'm just performing some xlog's in the onsend_route, but I'm not seeing it being called for replies. Currently my onsend_route looks like: onsend_route { xlog("onsend_route : $rm : Recieve Details $si:$sp -> $Ri:$Rp"); xlog("onsend_route : $rm : Destination Details $snd(af) $snd(proto):$snd(ip):$snd(port)"); } I can see it being executed for initial messages coming in but I dont see it executed for any replies. Thanks

kamctl dialplan addrule
by Arthur Alkhasyan 24 Oct '11

24 Oct '11

Hi all, I'm new to the list and new to the Kamailio. We are using Kamailio with Mysql to route calls between clients asterisks and SIP PSTN gateways. We have two inbound gateways and one outbound. I need to add outbound gateway and a few new features: 1. Call routing between carriers based at prefixes added by asterisks. I would like to route all calls with prefix 99101 to gateway 1 and prefix 99102 to gateway 2. Prefix have to be striped out before sending call to carrier. 2. Remote Call Forwarding. I have to setup RCF at Kamailio. All calls to the particular DID number have to be forward to another number. I found description for dialplan module and believe the module can work for me. I recompiled Kamailio with dialplan module support and added to config # ----- dialplan params ----- modparam("dialplan", "db_url", "mysql://openser:openserrw@localhost/openser") I did search and found this thread related to my problem: http://lists.sip-router.org/pipermail/sr-users/2009-November/025416.html I try to use kamctl to add rule to the MySQL and can't find proper syntax kamctl dialplan addrule 10 100 1 ^123+ 0 ^(123.+) 0030\1 -bash: syntax error near unexpected token `(' any help is greatly appreciated. Thank you.

Daily tarballs not being created anymore?
by Timo Reimann 24 Oct '11

24 Oct '11

Hi all, something caught my attention today: Apparently, tarballs provided from http://sip-router.org/tarballs/sr/ do not seem to be updated automatically anymore (the latest files are from March) although the Download page states that this should happen: "Tarballs for master (development) and several branches are made available daily (only if there were changes in the sources from previous tarball)" Is there a reason why tarball creation has ceased? If so, I think the Download page information should be corrected. I'd be prefer to have automatic tarballs again, however, as it's easier to point people not involved into development at tarballs instead of a set of git instructions. Thanks and cheers, --Timo

Force signalling??
by Skyler 21 Oct '11

21 Oct '11

Hi, I'm trying to setup an inbound proxy (Proxy-1) using dispatcher to relay between 2 other proxies (proxy-2 & 3) depending on DID, but I need to force all signalling through Proxy-1. so #2 & 3 only communicate with #1 and #1 only communicates up and down stream. My trouble is, the INVITES contain the original $ru $fu $tu & $ct info when passing down to Proxy-2 or 3. The result is, only partial signalling is being sent to Proxy-1. After the ACK it seems that Proxy-1 is removed from the communication path entirely as $ru becomes $rU@proxy-2 in the ACK from upstream so Proxy-1 is out of the picture from then on. This means BYE's are not working as Proxy-2 & 3 do not have authentication upstream. I suspect that I need to re-write $ru $fu $tu & $ct info on the original INVITE to reflect Proxy-1 information before dispatching. Is that what I'm missing? If so, how would I restore the original INVITE info to send upstream again on replies etc.? Any help is greatly appreciated. Tia, Skyler

Build version in custom server_header
by Asgaroth 20 Oct '11

20 Oct '11

Hi All, Is it possible to have the build/git version added in a custom server_header/useragent_header? For example, my kamailio version is: version: kamailio 3.2.0 (i386/linux) 94d3b8 if I had the following config options: server_header="Server: Proxy" useragent_header="User-Agent: Proxy" Is it possible to do something like: server_header="Server: Proxy ($buildver)" useragent_header="User-Agent: Proxy ($buildver)" Where "$buildver" is the build/git release (94d3b8)? I'm looking at the core cookbook but I dont see anything that jumps out at me, is there a variable that can do this? Thanks

ACK routing loop

Call flow: UAC INVITE -> Kamailio (with remote domain entered) -> UAS (host whose IP matches that remote domain) It looks like after loose_route() check ACK to 200 OK gets routed to local host. Besides this issue, IP address of remote host in 'domain' table did no harm at all. Question is, is that normal ACK routing behaviour or loose_route() should still check if given IP in request is really bound to local interface? Domain module documentation states that "A “local” domain is one that the proxy is responsible for", but id does not tell you that you cannot set remote IP address as a local domain. Please advice. Best regards, Antanas Masevicius

Dispatcher Confusion Redeux
by Asgaroth 20 Oct '11

20 Oct '11

Hi All, I'd like to clear something up with the diapatcher module and it's probing parameters: First things first: ./kamailio -V version: kamailio 3.1.5 (i386/linux) 76fff5 flags: STATS: Off, USE_IPV6, USE_TCP, USE_TLS, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, DBG_QM_MALLOC, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535, PKG_SIZE 4MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: 76fff5 compiled on 16:21:02 Oct 19 2011 with gcc 4.1.2 I think I am suffering from the same confusion as Klaus in the following archive message: http://web.archiveorange.com/archive/v/jZFTG61DlcEr9LJbS8Gq I have the following parameters set for the dispatcher module: modparam("dispatcher", "ds_ping_interval", 10) modparam("dispatcher", "ds_probing_threshhold", 1) modparam("dispatcher", "ds_probing_mode", 0) When I first start kamailio all gateways are active, no probing occurs. If I then set a gateway inactive (ds_set_state i 1 sip:...), no probing occurs. If I then set same gateway active (ds_set_state a 1 sip:...), no probing occurs. If I mark same gateway as probing (ds_mark_dst("p") after 1 attempt as specified in module parameter), then probing starts. If I then set same gateway inactive (ds_set_state i 1 sip:...) probing still occurs. According to the docs if I set the state of a gateway to inactive then no probing should occur. From my understanding of the docs, if I set ds_probing_mode to 0 then only gateways marked as probing will be "pinged". Can someone with more experienced than myself please clarify how this method is supposed to work. Thanks

kamailio and high-available db backend
by Mino Haluz 19 Oct '11

Hi, I was using ndb cluster as the dabatase backend for my kamailio setup. The thing is, mysql ndb cluster is difficult to maintain for me and it crashed multiple times (desynchronization, datamemory limit reached, and other strange reasons) and it is not that well documented (the user-base is quite narrow). My question is, what mysql architecture would you recommend me, if it has to be high available, well documented with various examples wihitn the community, thus easy to maintain. DB has 5% writes, 100queries/sec. and its size is 100MB. Mino

Kamailio Dispatcher fails in front of FreeSwitch, help (again).
by Henrik Aagaard Sørensen 18 Oct '11

18 Oct '11

I've asked a lot of question about Kamailio Dispatcher in front of FreeSwitch in this mailing list. So I'm sorry that I'm still "spamming", but it still fails. This is my status so far. When connecting 2 devices directly to FreeSwitch everything works. When connecting to Kamailio, some calls fails with "Timeout" and some fails with "Too many loops". This is my kamailio.cfg: http://pastebin.com/KEuZmikh When connected directly to FreeSwitch where everything works, this is how my clients are registrered in FreeSwitch: http://pastebin.com/prkjkb7g When connected to Kamailio where nothing works, this is how my clients are registrered in FreeSwitch: http://pastebin.com/b5x6NZyv 215.197.145.132 (sip.my-domain.com) is my Kamailio. pbx.my-domain.com is my FreeSwitch. 96.224.14.164 is my IP at home, where my 2 devices are from. Can anyone help me out? I'm kinda lost at this point.

master branch is now open for commits of new features to be in v3.3.0
by Daniel-Constantin Mierla 18 Oct '11

18 Oct '11

Hello, this is a short notice to let everyone know that the GIT master branch is open for commits of new features -- to be part of next major release v3.3.0, as v3.2.0 has been officially released few moments ago. From this moment on, master and 3.2 branches will diverge, 3.2 taking in only bug fixes. So if you want to use stable release of existing features, switch to branch 3.2. You can find guidelines of installing branch 3.2 in the wiki site: * http://www.kamailio.org/wiki/install/3.2.x/git I spotted already a new module by one of the community members submitted to the mailing list in the last days, related to presence extensions, therefore looks like is going to be another great development cycle until 3.3.0 will be out. Happy coding SIP routing extensions in SER and Kamailio!

preparing to release v3.2.0
by Daniel-Constantin Mierla 17 Oct '11

17 Oct '11

Hello, tomorrow is the day to release the new major version 3.2.0. Since involves creation of a new branch on GIT repository and some adjustments to the packaging, the plan is to start in the morning with the preparations. If any developer has something left to commit, please do it before 9:00am GMT. Afterwards it is very likely that the branch 3.2 will be created and there will be need for backport (which is fine as well). Then by 14:00 GMT the 3.2 branch should be frozen completely to start packaging the release. From than moment on until the release is announced, please send an email to sr-dev in case anyone wants to commit to branch 3.2.

Problem with REGISTER retransmissions
by Alejandro Mingo 17 Oct '11

17 Oct '11

Hi, Since we installed last version of Kamailio (3.1.4) we have been experiencing a big problem with REGISTER retransmissions. When the server receives a retransmitted REGISTER it removes the binding and the UAC remains unregistered until next refreshing period. I include a PCAP capture that shows this behaviour. I am not 100% sure that this problem never happened with older versions. Has anybody experienced the same problem? Thanks in advanced. Alejandro.

Re: [SR-Users] OPENSER MIB

Hello Stefan, On 3/14/11 11:03 AM, Stefan Tiedje wrote: > Thanks for the answer. > Maybe I have some older versions of the OPENSER-MIB and the other > related MIB's since I could not find the counter you pointed at. I'm > using a MIB browser for reading the MIB's. > Is the suggested counter "expired dialogs" added in a specific release > of Kamailio? Which? We use Kamailio 3.0.2. I used Kamailio and recommend using it sine it has the latest commits for stability. However, what I wrote before is pretty much not related to the version. There is a counter that tracks the processed dialogs, but seems it is not exported by default through snmpstats module. The statistics counter is named "processed_dialogs", implemented by dialog module. You can dump all internal statistics through kamctl or via xmlrpc command, but probably to export it through snmpstats you may need to extend the mibs and the code of the module. I just grepped the sources of snmpstats module to see what dialog statistics it is exporting: $ grep -n _dialogs modules_k/snmpstats/* | grep get_statistic modules_k/snmpstats/alarm_checks.c:83: num_dialogs = get_statistic("active_dialogs"); modules_k/snmpstats/snmpObjects.c:404: int result = get_statistic("active_dialogs"); modules_k/snmpstats/snmpObjects.c:424: get_statistic("active_dialogs") - modules_k/snmpstats/snmpObjects.c:425: get_statistic("early_dialogs"); modules_k/snmpstats/snmpObjects.c:443: int result = get_statistic("early_dialogs"); modules_k/snmpstats/snmpObjects.c:459: int result = get_statistic("failed_dialogs"); modules_k/snmpstats/snmpObjects.c:508: int num_dialogs = get_statistic("active_dialogs"); Perhaps when the snmpstats was developed the dialog module didn't export the statistics counter of "processed_dialogs" and then it was not updated. Now, what I tried to say is that if the "processed_dialogs" counter is not available through snmpstats (and it is not now after grepping the sources) you can get its value from another application through "kamctl get_statistics all" or XMLRPC command for all of the existing kamailio releases. Upcoming one we will look to implement the export through snmpstats as well. If you have time to do it and send us a patch, we will gladly commit it to source tree in our GIT repository.

cleaning up contacts...
by Krishna Kurapati 16 Oct '11

16 Oct '11

Hi, I am seeing several Contacts for same AOR in userlocation when I do "kamctl ul show". I suspect, it's a result of UA crashing after registering and then registering with different contact after restart. Since the UA crashed, it could not send Register with expire=0 to remove the previous contact. Since the userlocation API is not exported to configuration scripting, I am wondering how to clean any spurious contacts. Thanks Krish Kura

Force socket on reply
by Jijo 14 Oct '11

14 Oct '11

Hi All, Our system has two IP address, one is used for kamailio and 2nd one is used for data. The problem is suppose a request came in to kamailio on a TCP connection with first IP address and connection is torned down before sending the response. Later when the response is send out kamialio is using the 2nd IP to create the connection. The reason is kamailio doesn't have force socket in in reply, so it uses INADDR_ANY for soruce addres .so kernel uses source address based on the detaintion IP. I tired to force the socket using pseudo variable $fs or force_send_socket(), but neither of them worked from reply_route. So i modfied the code relay_replay to set the SND_F_FORCE_SOCKET which will use the address where request is recieved as source address to make the TCP connection The code change is shown below. Please let me know is there anyother way we could acheive it? }else{ buf = build_res_buf_from_sip_res( relayed_msg, &res_len ); /* if we build a message from shmem, we need to remove via delete lumps which are now stirred in the shmem-ed structure */ if (branch!=relay) { free_via_clen_lump(&relayed_msg->add_rm); } /* update send_flags with possible additions from the reply route */ SND_FLAGS_OR(&uas_rb->dst.send_flags, &uas_rb->dst.send_flags, &relayed_msg->rpl_send_flags); /* Make the response to use the same IP where it receives the message */ * * * uas_rb->dst.send_flags.f |= SND_F_FORCE_SOCKET; * } Thanks JIjo

a=nortpproxy:yes
by Austin Einter 13 Oct '11

13 Oct '11

If the SIP UA is not behind the NAT, and Kamailio insersts a=nortpproxy:yes in SDP body, can it cause one sided audio. I am using PJSIP as my UA, kamailio 3.1.5 , rtp proxy 1.2.1 as intermediate proxy for signalling and media. In kamailio config, I have enabled WITH_NAT. On call setup, only one way audio is there. When I looked at SIP messages, the only additional stuff I can see a=nortpproxy and nat=yes in recpord route. Without kamailio as intermediate proxy, audio is good both way. So I feel, when I bring up kamailio as intermediate proxy I am doing some mistake configuration wise either at PJSIP UA or in Kamailio. Has anybody faced this issue previously. If so please share how can we fix this issue. Thanks in advance Austin

Hi everyone. I'm still facing problems with my Kamailio Dispatcher <-> FreeSWITCH setup. Everything works when connecting directly to FreeSWITCH. When connecting to Kamailio, which should work as a dispatcher (load-balancer) in front of FreeSWITCH I get "Too many hops", "Timeouts" etc. My test setup with SIP clients is an iPhone, an Android, an iPad and a laptops with Ubuntu. Can someone help me out, for a small amount of money, until I can get it to work? Hopefully it's just the kamailio.cfg which needs to do things correctly. Currently I'm using this http://pastebin.com/mahKECAw with help from Morten in this mailing list.

Kamailio Dispatcher and FreeSwitch, Too many hops.
by Henrik Aagaard Sørensen 12 Oct '11

12 Oct '11

I have a setup with Kamailio as dispatcher in front of a FreeSwitch server. This is my kamailio.cfg: http://pastebin.com/8PR2GFBD I'm currently getting "Too many hops" when calling between SIP clients. I am able to call to FreeSwitch and listen to voicemail, hold music etc. After a long conversation with a FreeSwitch expert, and some tests, I was told that Kamailio delivers the wrong IP (NAT problems) to FreeSwitch. I've also run tshark on both FreeSwitch and Kamailio and when calling between clients they just send the packets between each other. Can anyone help me out? I've tried to Google a lot for this problem and asked in several IRC channels, mailing lists and forums. Without any luck.

Re: [SR-Users] Problem with Route containing two elements
by davy van de moere 12 Oct '11

Owki, reading RFC-3261 again ;) Imho Kamailio does what it is supposed to do, it forwards the packet to the first element in the Route header. But as I received the BYE packet from <sip:their_sbc> , that one should have stripped itself out of the Route header, making everything just work, right? Now I can hackishly fix it with a rewritehostport in the middle. But that will eventually not scale up that nicely. Ergo, does anyone have a good idea on how to e.g. have Kamailio in this situation ignore the first uri in the route header? Or am I still not getting it :) ? thx !

proxy BYE to itself
by caio 12 Oct '11

12 Oct '11

Hello, I have the following issue. A calls B, talk for a while, then B sends a BYE, but A never receives it. The BYE is transmited from the proxy listening interface:port to itself, but not to the asterisk port. U 2011/10/08 00:29:29.207335 Kamailio_IP:5060 -> Kamailio_IP:5060 BYE sip:Kamailio_IP;lr=on SIP/2.0. The scenario is: A (pstn subs) --> Asterisk:5080 --> Kamailio:5060 --> B (registered sip ua) Asterisk and Kamailio are in the same box, listening both at the same IP (eth iface) address, but one at port 5080, and the proxy at 5060 (udp). The configuration is based on kamailio.cfg file provided by the v3.1.5 (with a few modules added, like dialplan and cr..etc). If A is who send the BYE, everything goes well. I attach the full sip capture. Thanks for you time. Claudio

Problem with Route containing two elements
by davy van de moere 11 Oct '11

11 Oct '11

I'm trying to integrate to an integrics enswitch, almost everything works like a charm, except on BYE packets as Kamailio in my setup forwards these incorrectly. Digging somewhat I believe the culprit sits in the Route header which comes from the enswitch: Route: <sip:their_sbc;lr=on;ftag=as5716fec8>,<sip:36d0a5cfbaeb6b055d5bb02c32127b49_32123456789@my_kamailio ;lr=on;ftag=as5716fec8> Kamailio takes into account the first argument (the thing sip:their_sbc...) on which it cannot find the correct transaction. And forwards it back to the sender, instead of forwarding it correctly to my freeswitch. which gives a storm of traffic ;) If I compare that with an ACK packet in the same transaction , having this as a Route header : Route: <sip:36d0a5cfbaeb6b055d5bb02c32127b49_32123456789@my_kamailio ;lr=on;ftag=as5716fec8> Kamailio sends it along correctly. IMHO if I could convince Kamailio to always take the last part of the Route header into account and ignore the first one it would correctly work. What would be a good approach? Rewriting the route header looks abit harsch. disclaimer : I'm not sure which component is disrespecting the RFC, if any, or if I just fully not get something :) Short overview + packet detail (with some obfuscation): My setup: their_sbc --- my_kamailio --- freeswitch --- my_kamailio --- enduser BYE sip:05xxxxxx@my_kamailio:5060;transport=udp SIP/2.0 Record-Route: <sip:their_sbc;lr=on;ftag=as5716fec8> Via: SIP/2.0/UDP their_sbc;branch=z9hG4bK1ae8.269e4f67.0 Via: SIP/2.0/UDP their_internals:5060;received=their_internals;branch=z9hG4bK4f9044a7;rport=5060 Route: <sip:their_sbc;lr=on;ftag=as5716fec8>,<sip:36d0a5cfbaeb6b055d5bb02c32127b49_32123456789@my_kamailio ;lr=on;ftag=as5716fec8> Max-Forwards: 69 From: "Some_Telecom" <sip:02xxxxxxxx@their_sbc>;tag=as5716fec8 To: <sip:05xxxxxx@their_sbc:5060>;tag=U3FrFDm5Zr0KF Call-ID: 68fe6a470986bd087ce4ed860f603af6@their_sbc CSeq: 103 BYE User-Agent: Integrics Enswitch X-Asterisk-HangupCause: Normal Clearing X-Asterisk-HangupCauseCode: 16 Content-Length: 0 X-Enswitch-RURI: sip:05xxxxxx@my_kamailio:5060;transport=udp X-Enswitch-Source: their_internals:5060 BYE sip:36d0a5cfbaeb6b055d5bb02c32127b49_32123456789@my_kamailio;lr=on;ftag=as5716fec8 SIP/2.0 Record-Route: <sip:05xxxxxx@my_kamailio;lr=on;ftag=as5716fec8> Record-Route: <sip:their_sbc;lr=on;ftag=as5716fec8> Via: SIP/2.0/UDP my_kamailio;branch=z9hG4bK1ae8.b4f95af2.0 Via: SIP/2.0/UDP my_kamailio;rport=5060;branch=z9hG4bK1ae8.a4f95af2.0 Via: SIP/2.0/UDP their_sbc;rport=5060;branch=z9hG4bK1ae8.269e4f67.0 Via: SIP/2.0/UDP their_internals:5060;received=their_internals;branch=z9hG4bK4f9044a7;rport=5060 Route: <sip:their_sbc;lr=on;ftag=as5716fec8> Max-Forwards: 67 From: "Some_Telecom" <sip:02xxxxxxxx@their_sbc>;tag=as5716fec8 To: <sip:05xxxxxx@their_sbc:5060>;tag=U3FrFDm5Zr0KF Call-ID: 68fe6a470986bd087ce4ed860f603af6@their_sbc CSeq: 103 BYE User-Agent: Integrics Enswitch X-Asterisk-HangupCause: Normal Clearing X-Asterisk-HangupCauseCode: 16 Content-Length: 0 X-Enswitch-RURI: sip:05xxxxxx@my_kamailio:5060;transport=udp X-Enswitch-Source: their_internals:5060

Hi folks, I would like to show a project my colleage José Luis Millán and me are working on. It's about SIP protocol running in a web browser. When RTCweb (media capable web browsers) becomes a reality both technologies together will allow real SIP endpoints coded in JavaScript running in a web browser and interoperating with real SIP networks. Bye bye Flash and custom protocol gateways. http://sip-on-the-web.aliax.net/ Cheers. -- Iñaki Baz Castillo <ibc(a)aliax.net>

releasing v3.2.0
by Daniel-Constantin Mierla 11 Oct '11

11 Oct '11

Hello, it is time to set the time to release v3.2.0. From my point of view, testing went very well, considering also that core and main modules were not touched much during this devel cycle, the most of the efforts were on new modules and application service components such as presence server, Lua ... A convenient date for me will be Tuesday, October 18, 2011, allowing to work a bit on packaging and docs. If there are other preferences, jump in this discussion.

Audio quality issue
by Austin Einter 10 Oct '11

10 Oct '11

Hi I am using Kamailio 3.1.5 . I am using RTP proxy also. I have used default kamailio.cfg.sample fiile , and just added line #!define WITH_NAT. I have another Main proxy. I wanted all my signalling and media packets should just pass through machine where Kamailio and RTP proxy are running. With this I found, call is established, all signalling and media packets are passing through kamailio / rtp-proxy. So far so good. One way audio stream (from called party to calling party) quality is good. The other audio stream (from calling party to called party is very bad. Did anybody face this issue? Please help me to sort out this issue audio quality issue. Regards Austin

Hi, is there any setting which could allow me to set maximum memory per module ? As I am testing the carrier route module, I've added for testing purposes 100 000 rules sofar. When I start the kamailio, it gives me : Oct 10 14:46:46 kamrouter /usr/sbin/kamailio[2182]: ERROR: carrierroute [../../ut.h:702]: could not allocate shared memory from available pool Oct 10 14:46:46 kamrouter /usr/sbin/kamailio[2182]: ERROR: carrierroute [cr_rule.c:155]: could not allocate shared memory from available pool Thanks.

Kamailio RTP Proxy Questions
by Austin Einter 07 Oct '11

07 Oct '11

Hi I downloaded 3.1.5 Kamalio source, did make and install. Tried to run, and tested few basic scenarios, everything working fine. I have a main proxy, want to use kamailio as intermediate proxy and my requirement is all RTP packets should pass through machine in which Kamalio proxy is running. I beleive RTP Proxy I can run in same machine where Kamailio proxy is running with proper configuration . For this I am referring, http://nil.uniza.sk/sip/nat-fw/configuring-nat-traversal-using-kamailio-31-… page. In one of the steps it says "So, if we are using the Rtpproxy server with default configuration, we have to open /etc/default/rtpproxy file and uncomment following line regarding of udp socket, that will be sued for interconnection:". I tried to search rtpproxy configuration file, could not locate. While making and installing Kamalio proxy, the commands I used "make prefix=/usr/local/ all and make prefix=/usr/local/ install". Can somebody point me why rtpproxy config file is missing. Also the link I am refering to is correct or wrong one. Best Regards, Austin

Multiple INVITEs and discarded call_control
by Mino Haluz 07 Oct '11

07 Oct '11

Hi, my kamailio server is receiving from some customers 3 identical INVITEs when call is initiated (separated by 200ms). Those 3 INVITEs are making a big problem with call_control: WARNING: call_control [call_control.c:1156]: dialog to trace controlled call was not created. discarding callcontrol. That is why, the prepaid limit is not working at all in this case. This way the user can hack the prepaid protection of the account. Otherwise the call_control is fuilly functional. Anybody experienced the similar problem? If so, how to resolve it? Thanks, Mino Haluz

Problems with domain on registrations.
by Henrik Aagaard Sørensen 06 Oct '11

06 Oct '11

I have the current setup: SIP client <-> SER Proxy <-> SIP Trunk. My reason for the SER Proxy is that the SIP trunk only allows connections from approved IP addresses (such as my server with SER Proxy). My user on the SIP Trunk has the following authentication username@domain. I am able to register to the SIP Trunk as I'm setting up my SIP klient with username to username, domain to domain and then add my SER Proxy IP address as proxy. This works and means that I'm able to place calls to the SIP Trunk. BUT people cannot place calls from the SIP Trunk to my SIP client, due to the fact that on the SIP Trunk my locations is registered as username@SER-Procy-IP. So when people are calling me, the SER Proxy is looking for username@SER-Procy-IP and NOT username@domain, as I'm registered with. And then SER Proxy reports: 404 Not Found. Can anyone help me how to set this up correctly? I do not have access to the SIP Trunk, but I have all access to the SIP client and SIP Proxy.

Removing Contact from location table when TCP connection from UA is dropped...
by Krishna Kurapati 06 Oct '11

06 Oct '11

Hi, When UA connects with the Proxy over TCP, the contact is mostly bound to the firewall's binding IP and port for that connection. When the connection is dropped, the contact in Kamailio is no longer valid even though there is time left to expire the contact. Is there some way to link TCP connection and the contact in such a way that when TCP connection is dropped, contact from the location can be removed? Thanks Krish Kura

Balancing incoming traffic (DID)
by Anto 05 Oct '11

05 Oct '11

Hello It presents a problem because I do not know how to assimilate the implementation. Until now we had a design of a proxy to balance out between several gateway, but it will add another proxy for another service (other users) and use the same gateway output or perhaps different (although not that be better if divide or unify the gateway). The problem as I have with the routing entry, which is not very well how to implement it. Now we have the design like this: -GW ----\ / - CARRIER1 USER ------ KAMAILIO ----- GW ---- + \ - CARRIER2 -GW ----/ And becomes like this: -GW ----\ / - CARRIER1 USER ------ KAMAILIOSERVICE1 ----- GW ---- + \ - CARRIER2 -GW ----/ -GW ----\ / - CARRIER1 USER ------ KAMAILIOSERVICE2 ----- GW ---- + \ - CARRIER2 -GW ----/ Or maybe using the same gateway. The problem is that each carrier provides DID number (I use the same for both services). Kamailio had thought to put a gateway between the carriers and that they did check the service and send it to the corresponding gateway (in the case of the gateway separately), or put it in the proxy gateway and making checking for routing to proxy (in the case of using the same gateway). What would be better? Any recommendations on how to put this into practice?. The biggest question that I believe is the routing table, as if this new proxy routes the traffic into and leaves her in the field via ip, also pass through the output data (I have doubts whether SIP level, following standard, you can not pass through the exit) and want it to be direct (USER -> Proxy -> GW -> CARRIER), just past the entrance. Anyone could advise me where I could find more information to set up this scenario?. thanks and sorry for bothering you with this question ;-). best regards

Installing Versign Intermediate CA Certificate In Kamailio 3.1.5
by arif tuhin 05 Oct '11

05 Oct '11

I've got trial certificate from verisign. They signed the server certificate with an intermediate ca and gave instructions for installing it into apache/IIS etc. Both issued certificate and the intermediate CA should be installed in the server. if only server certificate is installed , it will not be trusted by default. Now problem is in apache mod_ssl there is a field called ServerChainFile where the intermediate ca name should be in place, but in the tls module documentation, i find no place for intermediate ca. How should i install the intermediate ca the? Thanks in advance.

db_text
by Bruno Bresciani 04 Oct '11

04 Oct '11

Hello ALL, Someone knows why at line 149 in .../kamailio-3.1.2/modules_k/ db_text/dbt_tb.c the shm_malloc function sometimes allocates memory to dtp->prev but sometimes doesn't? I'm asking this question because when the subscriber table is being loading to shared memory in db_text module, dtp->prev is allocated but on version, dispatcher, location table it doesn't... Analysing the source code I can't see any reason to this behavior. The allocation of dtp->prev to subscriber table is generating a core at db_text module. Best Regards

new wiki system
by Daniel-Constantin Mierla 04 Oct '11

04 Oct '11

Hello, I installed a new wiki site, targeting to collect documentation for upcoming v3.2.0 and further releases. You can find it at: * http://www.kamailio.org/wiki/ Hopefully, it will make the process of updating/migrating the relevant documentation from old wiki (http://www.kamailio.org/dokuwiki/) straightforward and offer a clean reference for upcoming stable version. Old wiki is in place since 2005, collected a lot of pages, but many are for very old versions of kamailio, making difficult, at least for new comers, to sort out documentation for latest stable. All of you are invited to help with this process of adding documentation for 3.2.0 on the new wiki. The old wiki will stay in place, it will not be removed. Both are based on Dokuwiki, using different themes. The new one is at the beginning, so no much content in there yet, but by the time of releasing 3.2.0, should contain sufficient documentation for get started with that version. One very demanded thing was the alphabetic index for parameters, functions and mi commands from modules. This page contains new generated indexes for version 3.2.0. More details in a separate email. If you have questions about the new wiki, don't know where to place some tutorial, feel free to ask on mailing lists. Ultimately, pages can be relocated, but try to use namespaces for related topics.

dispatcher, LCR, carrierroute or mtree?
by Skyler 04 Oct '11

04 Oct '11

Hi all, I need to setup an inbound DID router for 8 proxies and ~300 DID's. Very simple, a call comes in from pstn > kamailio looks up DID for exact match in mysql > returns location > If db result returns noservice redirect to 1.2.3.4 else remain in call-flow and send to destination. Having a failure route capability would be nice. From what I've read on each of the 4 modules, any could do what I need though each have their own complexities. I'm still new to kamailio and hoping to utilize the group here for some advice. I'd like to keep this as simple as possible then adding/deleting DID's from the db as needed for routing. In your experience which would be the best module to use in order to achieve my goal? TIA, Skyler

Trouble Setting up Kamailio
by Peter Schrock 04 Oct '11

04 Oct '11

I am using the site: http://www.kamailio.org/dokuwiki/doku.php/install:kamailio-3.1.x-from-git to load up Kamailio on my ppc using Leopard X. I managed to figure out the mysql issue and got it to install, but now there are some variances to the instruction from the stated install site and I am kind of lost. If I could get some help with the following - "7. Create MySQL database" This whole section seems confusing. It doesn't say what I am suppose to look for. I am sure what it says is all you need to do, but I am not sure if it is completed correctly or not. - "8. Edit configuration file" This section could use more specific information as to how to set up the configuration file. - "9. The init.d script" This section says I am suppose to put "*kamailio.init*" in the directory "*/etc/init.d*", then I am suppose chmod after it is copied. First of, I don't have that directory, am I suppose to create it or is it suppose to be created already? Also, it says to "*adduser*" with some options. Every time I try, I get the error message that it doesn't recognize the "*adduser*" command. Please help Peter

New to Kamailio - make problem
by Peter Schrock 03 Oct '11

03 Oct '11

I can't seem to get kamailio to "*make*". I am following the directions on the wiki on how to install. I have downloaded, compiled, and installed mysql server and every time I run to "*make all*" with kamailio, I get this error message. At first, I was thinking that *km_db_mysql.c* couldn't find the file. The header seems to be looking for *mysql.h* (at *#include <mysql/mysql.h>*). I found the file from installing mysql server and I thought I'd help * km_db_mysql.c* to find the file, but it still gives me this error. I am using a power pc running OS X.5.1. CC (gcc) [M db_mysql.so] km_db_mysql.o km_db_mysql.c:49:19: error: mysql/mysql.h: No such file or directory km_db_mysql.c: In function ‘kam_mysql_mod_init’: km_db_mysql.c:92: warning: implicit declaration of function ‘mysql_get_client_info’ km_db_mysql.c:92: warning: format ‘%s’ expects type ‘char *’, but argument 7 has type ‘int’ km_db_mysql.c:92: warning: format ‘%s’ expects type ‘char *’, but argument 6 has type ‘int’ make[1]: *** [km_db_mysql.o] Error 1 make: *** [modules] Error 1 Peter Schrock

Combining Dispatcher and NAT_Helper modules.

03 Oct '11

I'm currently having a Kamailio running as load balancer, at it works most of the time. But sometimes fails due to NAT issues. This is my config: http://pastebin.com/8F8X45xh Can someone help me combine the NAT_Helper module into this config? It's not the variables to set or RTPProxy, but in the Routing Logic.

Incoming calls question
by Javier Vidal -- Quasar 03 Oct '11

03 Oct '11

i have a question, i have to make a system to recieve several calls and the same time, and depending of destination DDI i have to rewrite the URI's IP. I am not going to have Registered users, only IP validation. The question is: What is the better way to consult thousands DDIs and get the IP from mysql? I had thought, use sqlops.so module, but i think that i could have problems with it. Another posibility is use the carrierroute and use the full pattern for the DDI. Thank for all sugestions.

alphabetic indexes for module parameters, functions, ...
by Daniel-Constantin Mierla 03 Oct '11

03 Oct '11

Hello, for the last versions the alphabetic indexes were not generated - there were different people doing that in the past, using various self-written tools. For upcoming version, 3.2.0, I spend some time to structure the docbook files for modules in order to be easier to get from them the names for functions, parameters and mi commands. Therefore, the new wiki system has fresh generated indexes from modules' documentations. You can find them at: * http://www.kamailio.org/wiki/alphaindexes:3.2.x:modparameters * http://www.kamailio.org/wiki/alphaindexes:3.2.x:modfunctions * http://www.kamailio.org/wiki/alphaindexes:3.2.x:micommands Being generated from docbook xml files, the indexes contain name, path to the module in source tree and module name, the last one with link to html readme file of the module published to kamailio.org site. There is no link at the moment pointing inside the html readmes to the place where the item is documented, but each readme has table of content, so it is easy to spot it. We have lots lots of modules right now, therefore it was not easy to check if some parameters, functions or mi commands were not indexed. If you find some missing, please write back here so we can fix the dockbook or the indexing tool, depending where the problem is. Hope the indexes will be helpful for many of you. Ending the email with another invitation to all of you to port (update to upcoming v3.2.0) your favorite tutorial from old wiki system (http://www.kamailio.org/dokuwiki/) and add to the new wiki (http://www.kamailio.org/wiki/).

Cflag is not getting updated.

Hi, I am hitting bit of a wall here. - I am setting bflags for NAT, and SIPPING before save("location") however, when I do "kamctl ul show", the Cflag is 0. I also checked see if the bflags are set or not in the register routine - they are being set. What am I missing? snippets of the config files. #!define FLB_NATB 6 #!define FLB_NATSIPPING 7 modparam("nathelper", "natping_interval", 30) modparam("nathelper", "ping_nated_only", 1) modparam("nathelper", "sipping_bflag", FLB_NATSIPPING) modparam("nathelper", "sipping_method", "INFO") modparam("nathelper", "sipping_from", "sip:pinger@50.62.1.7") # params needed for NAT traversal in other modules modparam("nathelper|registrar|usrloc", "received_avp", "$avp(RECEIVED)") modparam("usrloc", "nat_bflag", FLB_NATB) # Caller NAT detection route route[NAT] { #!ifdef WITH_NAT force_rport(); if (nat_uac_test("19")) { if (method=="REGISTER") { fix_nated_register(); } else { fix_nated_contact(); } setflag(FLT_NATS); setbflag(FLB_NATB); } #!endif return; } # Handle SIP registrations route[REGISTRAR] { if (is_method("REGISTER")) { xlog("L_ALERT", "REGISTER: From $fU, $fd To $tU, $td"); if (isflagset(FLT_NATS) || isbflagset(FLB_NATB)) { setbflag(FLB_NATB); # uncomment next line to do SIP NAT pinging setbflag(FLB_NATSIPPING); } # 7/28/11 - make sure only one contact location is active # at any given time # unregister("location", "$rU"); if (isbflagset(FLB_NATB)) { xlog("L_ALERT", "REGISTRAR: For $fU, $fd FLB_NATB set"); } if (isbflagset(FLB_NATSIPPING)) { xlog("L_ALERT", "REGISTRAR: For $fU, $fd FLB_NATSIPPING set"); } if (!save("location")) { xlog("L_ALERT", "REGISTRAR: From $fU, $fd Location could not be saved"); sl_reply_error(); } exit; } } The debug log snippets ================== Oct 1 15:58:30 siptest /usr/sbin/kamailio[19515]: ALERT: <script>: REGISTER: From p_krishna_test_com, 50.62.1.7 To p_krishna_test_com, 50.62.1.7 Oct 1 15:58:30 siptest /usr/sbin/kamailio[19515]: ALERT: <script>: REGISTRAR: For p_krishna_test_com, 50.62.1.7 FLB_NATB set Oct 1 15:58:30 siptest /usr/sbin/kamailio[19515]: ALERT: <script>: REGISTRAR: For p_krishna_test_com, 50.62.1.7 FLB_NATSIPPING set Oct 1 15:58:30 siptest /usr/sbin/kamailio[19515]: DEBUG: sl [sl.c:278]: reply in stateless mode (sl) Output of kamctl command ==================== $ sudo kamctl ul show Domain:: location table=512 records=1 max_slot=1 AOR:: p_krishna_test_com Contact:: sip:p_krishna_test_com@75.62.17.45:50073;transport=tcp;ob Q= Expires:: 287 Callid:: ad2d3a7bf39a4345861db1661576a7f3 Cseq:: 54856 User-agent:: QliqDesktop 1.0.0 (pjproject 1.10.0/win32) State:: CS_NEW Flags:: 0 Cflag:: 0 <================= Cflag is not being set.

Kamailio as dispatcher fails due to from domain on extension.
by Henrik Aagaard Sørensen 02 Oct '11

02 Oct '11

I'm using Kamailio as dispatcher to a FreeSwitch setup. Currently it "almost" work. I have 2 extensions connected to my FreeSwitch via Kamailio. However, I can only send calls one way because Kamailio seems to change the domain on the extension. One extension is registered with ID(a)sip.my-domain.com. This I can send calls to. The other extension is registered with ID@local-ip. This I cannot send calls to. Isn't it possible to have Kamailio register the extension on my FreeSwitch with @sip.my-domain.com? If I register both extension directly to my FreeSwitch everything works.

Setting avp from load_credentials
by Graham Wooden 01 Oct '11

Hi there, Just doing a quick test and this doesn¹t appear to be working. Kamailio 1.5.5-notls. Snippet of code: modparam("auth_db", "load_credentials", "username") . . . xlog("username is $avp(s:username)\n"); The result is '<null>'. Is this not available in the route{} ? Thanks, -graham

Handling quota/call limits - kamailio 1.5
by Graham Wooden 01 Oct '11

01 Oct '11

Hi there, Finally getting around to introducing some call limits and starting with the inbound calls. However, I ran into an issue about how to get the "in use" count to be updated in my quota table. What is the best way to get s:in_use to update so it can be calculated? Here is my snippet of code: if (is_method("INVITE")) { avp_db_query("select quota, in_use from quota where username='$rU'","$avp(s:quota);$avp(s:in_use)"); if ($avp(s:in_use) >= $avp(s:quota)){ xlog ("DEBUG: Trunk $rU is over quota"); sl_send_reply("503","User over quota"); } . . } This opens up two more questions: How to decrease the call count when a BYE is received - maybe do a subtraction and the do a avp_db_query to update the table? And of course there is the BYE that won't be present (ie. When a call just rings and hangs up before it gets answered). Maybe ACC's missed_calls can somewhat be used to help determine? Thanks for any pointers and guidance. I am running Kamailio 1.5. Thanks, -graham

SNMPStats and multiple proxies
by Antanas Masevicius 30 Sep '11

30 Sep '11

Hello, been trying to run two sip-router proxies in parallel and to feed data from them to snmpd via agentx. But it looks like snmpd deamon directly routes snmp request just to one (probably first connected) proxy. What ways this can be solved? Currenly i am thinking like running two concurrent snmpd daemons binded to specific IP addresses. Is there a better way to do it? best regards, -- Antanas Masevicius

Hi, When a user is removed using "kamctl rm", is there way way to clean up presence information in the database (xcap, presentity, watcher and active watcher tables) and in the cache? Is there a event that gets fired when the user is removed from subscriber table which I could handle in config file and and cleanup? Thanks Krish Kura

Re: [SR-Users] Placing ds_select_dst in kamailio.cfg, where?
by Daniel-Constantin Mierla 29 Sep '11

29 Sep '11

Hello, please keep the mainling list cc-ed. Calling ds_select_dst() first in the main route block is not really a good place. First you have to handle sanity checks, within dialog requests a.s.o. Of course it is a matter of your purpose, but as general hint, selecting the destination should be done just (or as close as possible) before relaying. If you take default config and you have only load balancing, then you can replace location lookup part with load balancing. Other parts may be stripped as well, just giving some direction here.

simple question but can't find the answer
by JJ Zeng 29 Sep '11

Hi, I am really new to ser(just installed it today). My situation is here: Both A and B make tcp connection to ser proxy server. If A sends "Invite" to B, ser would look up the tcp connection of B, and relay the sip request. If B is not connected, then 480 is returned to A. When B sends back the response, ser would relay it to A. It looks really simple, but I just can't figure out how to do it. Thanks. JJ
