Connecting Two OpenSER machines
by SR-USER 11 Jun '10

11 Jun '10

Hi everyone. I have two machines running OpenSER, one machines runs OpenSER A and the other runs OpenSER B. Phone A registers in OpenSER A while Phone B registers in OpenSER B. I would like to allow Phone A call Phone B, but not the other way around. I am a newbie so sorry for my lack of knowledge. Would should be my configurations files for OpenSER A and B? Thanks in advanced

kamailio 3 and cpl - 483 too many hops
by Karl Harris 11 Jun '10

11 Jun '10

I am trying to incorporate a cpl script for testing purposes with kamailio 3 but have been met with failure with each try. Test scenario I have two sip phones registered to kamailio successfully (I can make phone calls between the two phones). The CPL XML is as follows: <?xml version="1.0" encoding="UTF-8"?> <cpl> <incoming > <location clear="yes" url="sip:1000@192.168.254.144<sip%3A1000(a)192.168.254.144>" > <log comment="cpl-log - just location" /> </location> </incoming> </cpl> This compiled successfully and is populating the cpl table in the openser database. When I call this from kamailio.cfg I get the 483 (Too many hops) error. If someone could spot an obvious error, I would appreciate it. The current kamailio.cfg file is as follows: ------------------ debug=8 log_stderror=yes memdbg=5 memlog=5 log_facility=LOG_LOCAL0 fork=yes children=4 /* uncomment the next line to disable TCP (default on) */ disable_tcp=yes /* uncomment the next line to disable the auto discovery of local aliases based on revers DNS on IPs (default on) */ auto_aliases=no port=5060 /* uncomment and configure the following line if you want Kamailio to bind on a specific interface/port/proto (default bind on all available) */ listen=udp:192.168.254.144:5060 ####### Custom Parameters ######### #

Match ip source of response into failure_route
by inge 10 Jun '10

10 Jun '10

Hi all, I try to do something like this on my failure_route[1] : if (t_check_status("503")) { if (ip_src==A.B.C.D) { ... } } The goal, is to prevent a 503 from a PSTN gateway and try another one for terminating the call. But, I realize that "src_ip" is the IP source of SIP Request. What could be a possible way to match IP source of the 503 responses ? Regards, Adrien L.

domain name
by Anders 10 Jun '10

10 Jun '10

Hi, I have a carrier who insists and have configured their system so they can receive INVITEs to their domain name only, and not the IP. I cannot configure the gw for anything but IPs, but thought that I might be able to replace the IP address in the cfg. So I tried with setting $dd = "domain.com"; but that's not working, - I guess $dd is read-only or something. Any ideas? Thanks!! //Anders

See the > stock configuration file for more insight. Thanks Alex. I am testing this in the lab so I don't have a production config loaded, I am really focused on the carrierroute module and trying to figure that out so I'm running bare bones using the module example. I looked into the RR functions and read in the CR module that it invokes the TM when necessary so I was thinking it would take care of keeping track of dialogs. The thing that threw me off was the handling of the scenario 1 session with sipp was ok but with asterisk scenario 2 it was not. So I loaded in the record_route function in the main routing block and it did take care of the complete session with the asterisk server, so that problem is solved. What I am running into now is the failure route. If the initial session can not compete to the fist carrierroute, the call switches over to the failure-route[1] which invokes carrierroute again with another domain. Then the receiving asterisk server retransmits the initial OK 6 times, so the transaction is lost or not held in kamailio state, then the whole session drops after a few more seconds. I think there is something going on with the append_branch function that is throwing me off. It is needed so the failure route completes but it's not handling the complete dialog or I could be totally off. Thanks. JR -- JR Richardson Engineering for the Masses

Kamailio 3.0.1 and NAT
by Information 09 Jun '10

09 Jun '10

hi, I have configured kamailio 3.0.1 on fedora 12 and its working fine for ips on the network. But I am unable to get a working configuration for a natted client. If one client is natted and other is not, both can call each other through the kamailio server but only the natted client sends voice to the un-natted client while on tcpdump i found that the un-natted client is actually seeing the private ip of the natted client and trying to deliver packets there. So no sound reaches the natted client from the un-natted client. I have been searching for some days for some help in this regard but have not found anything i can use. help, regards. ***********************Confidentiality Notice*************************** The information contained in this electronic message and any attachments to this message are intended for the exclusive use of the addressee(s) and may contain confidential or privileged information.

2 Asterisk servers re-inviting around kamailio even with t_relay being used?
by JR Richardson 08 Jun '10

08 Jun '10

Hi All, I'm using kamailio with carrierroute to load balance calls to other servers. I have 2 testing scenarios set up: sipp><kamailio><asterisk server In the above scenario all SIP transactions, dialogs go through kamailio, INVITE, Trying, ACK, OK, BYE, OK Here is another one: phone><asterisk><kamailio><asterisk server In this scenario only the initial INVITE, ACK and OK go through kamailio, then the 2 asterisk servers finish the session directly to each other with ACK, BYE and OK In both asterisk servers, canreinvite=no is set in peers and general section in sip.conf. The kamailio cfg is using t_relay. No errors are coming up anywhere. Here is a pastebin of the 2 asterisk traces and the kamailio config. http://pastebin.com/Uk9qVhX2 Any ideas on why the call is not maintaining SIP session through the proxy? Thanks.

Ending a dialog via MI
by Iñaki Baz Castillo 05 Jun '10

05 Jun '10

Hi, I'm building an external application in order to end dialogs via XMLRPC MI (Kamailio 1.5.4). For each call of a client I set a dialog profile: dlg_manage(); set_dlg_profile("out","$avp(AVP_CLIENT_USERNAME)"); The problem is that there is no way to find the current dialog information based on dialog profiles, as such information is not provided when running MI dlg_list or dlg_list_ctx. So, is there something I can do? I've realized that dlg_list_ctx also displays the dialog "context": "associated context from modules sitting on top of the dialog module" But of course such field is empty as I don't use a module on top of dialog module. But perhaps I could code something in the dialog module so such value could be set in the script (I need it to display $avp(AVP_CLIENT_USERNAME)). In this way, I would get the dialog list and filter these with "context = SOME_CLIENT_USERNAME". Then I get the h_entry and h_id and can perform the dlg_end_dlg MI command. Any suggestion about it please? BTW: Running dlg_list_ctx via MI FIFO I get this for each dialog: dialog:: hash=3960:1144646733 Should I assume that h_entry is 3960 and h_id is 1144646733? Thanks a lot. -- Iñaki Baz Castillo <ibc(a)aliax.net>

mysql queries per sec forever rising...almost
by Anders 05 Jun '10

05 Jun '10

Hi, I use Munin to try to understand what's going on on the server that runs Kamailio (with Siremis). One thing that puzzles me is that if I look at the MySql queries per second, it just keeps going up. The number rises during the time with calls - the more calls the more it rises - and then when there are no calls, it stays at the same level. And this is what I don't understand - when Kamailio is doing nothing, why are there 5k queries per second? Sometimes - every few weeks - it takes a steep drop to very few queries per second... - and then back to rising again. Is this a database issue, a Siremis issue, or a Munin issue? Or is it just something I don't understand that it's supposed to keep rising forever? Thanks! //Anders

Hi Jasmin, ah, sorry. Its not available or necessary anymore in 3.0. In 1.5 it also affected the branch_route, i think, but for the newer version this behaviour is now the default. Then in your case its probably another problem.. Cheers, Henning

check_from and check_to: case sensitive?
by Iñaki Baz Castillo 03 Jun '10

03 Jun '10

Hi, when using check_from or check_to, is the username part of the uri checked in mode case sensitive or insensitive? It should be case sensitive as per SIP grammar. But in the code (uri_db/checks.c) I see the opposite: /* URI table not used, simply compare digest username and From/To * username, the comparison is case insensitive */ if (_uri->user.len == c->digest.username.user.len) { if (!strncasecmp(_uri->user.s, c->digest.username.user.s, _uri->user.len)) { LM_DBG("Digest username and URI username match\n"); return 1; } } -- Iñaki Baz Castillo <ibc(a)aliax.net>

Hello, next Wednesday (June 2, 2010), at 18:00UTC, I will participate to FreeSWITCH weekly conference call, talking about using Kamailio and FreeSWITCH together. The draft of agenda is: * Goals of Kamailio, how it differentiates from FreeSWITCH and why using them together creates a very powerful framework to build large VoIP systems. * Kamailio for sip routing and FreeSWITCH as media server (conferencing, voicemail, IVR, announcements) * FreeSWITCH as a B2BUA for Kamailio (topology hiding, transcoding, call interrupt detection) * FreeSWITCH as prepaid engine for Kamailio * Load balancing FreeSWITCH servers with Kamailio Is an open debate, join and ask your questions. You can dial in via SIP, Skype, PSTN, see access details at: http://wiki.freeswitch.org/wiki/FS_weekly_2010_06_02 Cheers, Daniel -- Daniel-Constantin Mierla Kamailio (OpenSER) Advanced Training Miami, Fl, USA - June 21-23, 2010 http://www.asipto.com/index.php/kamailio-advanced-training/

fix_nated_contact() on REGISTER
by Klaus Darilion 02 Jun '10

02 Jun '10

Hi! Does somebody know what happens when I call fix_nated_contact() and save() on a REGISTER request? What will be stored and used as RURI? The original contact URI or the fixed one? I would guess the original one, as message manipulations are not visible when calling save() - true? regards Klaus

Siremis with grandchild(?)
by Anders 29 May '10

29 May '10

Hi, This might not be directly Siremis-related, but in any case it is a consequence of using Siremis: The stored procedure for calculating and populating the 'cdrs' table has started to act out all of a sudden - it won't do anything. In my syslog it looks like this: May 29 09:24:01 vae /USR/SBIN/CRON[25555]: (root) CMD (echo "call kamailio_cdrs();"|/usr/bin/mysql -u root -pxxx kamailio >/dev/null) May 29 09:24:23 vae /USR/SBIN/CRON[25548]: (CRON) error (grandchild #25549 failed with exit status 1) May 29 09:24:23 vae /USR/SBIN/CRON[25548]: (CRON) info (No MTA installed, discarding output) ..and that's every time the cron job runs, the only thing that changes is the "grandchild" number. I have no clue what "grandchild" means in this context - ...anyone? Thanks!! //Anders

Issue with starting SER
by Jesse B Scites 28 May '10

28 May '10

I am not sure if this mailing list is for any type of product support, but I am at a loss as how to continue, so any type of guidance would be appreciated. I am new to using SER, however I downloaded the source baseline, then made it, etc. according to the "Getting Started" guide. The very basic configuration (minus MySQL, etc.) seemed to build fine and all binaries, the ser.cfg file, etc. were installed to the correct locations. Since I just wanted to start using a basic configuration, I chose to use the "Hello World" configuration file as outlined in the guide, so I swapped it out with the default one. As the super user, I ran >>ser -V and received the expected version feedback as listed within the "Getting Started" guide. However, when I tried to start SER normally with >>ser I received the following error: 0(6989) parse error (11,1-5): syntax error 0(6989) parse error (11,1-5): ERROR: bad config file (2 errors) So I went back and checked the "Hello World" config file and I could find no syntax errors since the exact replica can be compared to the example in the "Getting Started" guide. So I swapped back in the original ser.cfg file and I still got errors. Of course I also got additional errors with that file since I did not have MySQL, etc configured. So I guess my question would be, what may be causing SER to error out on the config file (I assume it means there is some issue with parsing out the contents of the ser.cfg file). I am using Fedora 11 on an i386 platform with gcc 4.4.1, bison 2.4.1, flex and all other needed dependencies listed within the INSTALL file. Any suggestions would be much appreciated.

new developer access: Jon Bonilla
by Daniel-Constantin Mierla 28 May '10

28 May '10

Hello, lately, most of the bugs related to Debian packaging were filled by Jon Bonilla (Manwe), so the solution was to ask him to join and help to fix/improve the spec files. Jon has been around for quite some time, working with other SIP related projects as well. I am looking forward to his contributions to packaging system, part which was not much under focus lately, but needs to be brought up-to-date to ease the installation on various OSes. His commit id is: manwe Welcome Jon!

continue processing route script if no response from gateway
by JR Richardson 28 May '10

28 May '10

Hi All, I am lab testing carrierroute modue on kamailio 1.5.4-notls (i386/linux) and have a question on how to continue processing a call if kamailio sends a call with t_relay() but does not get a response from the gateway. I read about the timers in the tm module and set them pretty low in the config file: # ----- tm params ----- modparam("tm", "fr_timer", 2) modparam("tm", "fr_inv_timer_next", 3) But nothing happens in the routing script after an invite is sent and there is no response. Debug just shows the invite to the gateway being re-transmited several times. Any ideas? Thanks. JR -- JR Richardson Engineering for the Masses

RPID Question
by dotnetdub 28 May '10

28 May '10

Hi All, Kamailio 3 I currently store a default RPID in our database. We allow some asterisk customers to send us the RPID. I want to store the RPID sent by the customer on the radius record. We test: if!(is_present_hf("Remote-Party-ID")) { #RPID Not Set by Asterisk - Will set now from DB append_rpid_hf(); } Do I use textops to get the RPID that the Asterisk sends and then overwrite what we read from the database? $avp(s:rpid) = ? Not really sure how to extract the RPID from the SIP message sent from the asterisk. TIA. Stephen.

new feature: embedded http 1.0 server
by Daniel-Constantin Mierla 28 May '10

28 May '10

Hello, there is a new module named xhttp which provides an embedded http server inside the SIP server. It reuses the transport layer from the core, so you can send http requests via TCP and TLS. The port is the same as for SIP traffic. The documentation of the module is available at: http://sip-router.org/docbook/sip-router/branch/master/modules/xhttp/xhttp.… Since sip and http are very similar, you can use other modules in handling the http requests. For example, you can do www-authentication: event_route[xhttp:request] { if (!www_authorize("xcap", "subscriber")) { www_challenge("sip-router.org", "0"); exit; } xhttp_reply("200", "OK", "text/html", "<html><body>Welcome $au, you are connected from $si:$sp</body></html>"); } allowing in this way only local SIP users to do http requests. For now supports only http 1.0, meaning it cannot take chunked requests (usually happening in PUT requests with large body). Hope it is useful for some of you. Its main goal right now is to offer the transport layer for embedded xcap server (the new xcap_server module), but it can be used for service monitoring, server control, etc. Cheers, Daniel -- Daniel-Constantin Mierla Kamailio (OpenSER) Advanced Training Miami, Fl, USA - June 21-23, 2010 http://www.asipto.com/index.php/kamailio-advanced-training/

Carrierroute failover domain not working
by JR Richardson 27 May '10

27 May '10

Hi All, I'm testing carrierroute modue in kamailio 1.5.4-notls (i386/linux). I have things working like this: sipp><kamailio carrierroute>< 2 asterisk servers A & B even distribution of calls So A & B are in carrier1 domain1, I have failureroute setup with 2 more asterisk servers C& D in carrier1 domain2. While I'm processing calls from sipp and sending to A & B, I can fail A and then all calls go to B as expected. But if I fail both A & B, the calls fail, so I'm guessing I don't have the faliure_route configured correctly. Here is my current config: route { if (!mf_process_maxfwd_header("10")) { sl_send_reply("483","Too Many Hops"); exit; } if ($rU==NULL) { # request with no Username in RURI sl_send_reply("484","Address Incomplete"); exit; } if (msg:len >= 2048 ) { sl_send_reply("513", "Message too big"); exit; }; if (!allow_trusted()) { sl_send_reply("403", "Forbidden"); exit; }; if (is_method("CANCEL")) { if (t_check_trans()) t_relay(); exit; } t_check_trans(); route(2); } route[1] { if (!t_relay()) { sl_reply_error(); } exit; } route[2] { if(!cr_route("1", "1", "$rU", "$rU", "call_id")){ sl_send_reply("403", "Not allowed"); } else { t_on_failure("2"); route(1); } } failure_route[2] { if (t_check_status("408|5[0-9][0-9]")) { if(!cr_route("1", "2", "$rU", "$rU", "call_id")){ t_reply("403", "Not allowed"); } else { t_relay(); } } } I think the database entries are setup ok, I used the example in the module doc, but I can share that if needed. Any guidance will be appriciated. Thanks. JR -- JR Richardson Engineering for the Masses

A Couple of Questions about carrierroute moduel
by JR Richardson 26 May '10

26 May '10

Hi All, I'm testing carrierroute module on version: kamailio 1.5.4-notls (i386/linux). I'm distributing calls to a group of Asterisk servers, all in the same carrier and domain, wanted to load balance the calls and I'm curious how this works. I see the 'probability' parameter in the carrierroute table and set it to equal value across all servers, I have 4 servers I'm sending calls to, so I set each prob value to '0.25'. I'm testing with sipp and hashing over call_id so this is the same for every call. I send 40 calls and the distribution of calls to the asterisk servers are 11, 12, 6, 11, pretty close to even but not 100%. How does the distribution algorithm work for carrieroute? Does it statefully track all active calls and load balance across each server in destination group? Is there another algorithm that can offer that can get closer to a round robin effect? Another question is do I need to include the record_route() and the t_check_trans() functions prior to calling the carrierroute functions? I see in the debug "DBG:core:forward_reply: found module tm, passing reply to it" and dialogs seem to process fine, so does the carrierroute module handle those requirements for stateful processing? Thanks. JR -- JR Richardson Engineering for the Masses

permissions module
by Asim Riaz 25 May '10

25 May '10

Hello List, from the documentation, permissions.allow, allows the calls either by matching From-URI or R-URI and permission.deny denies the call from matching uri. Do I need to divide the file into different sections, for R-URI and for From-URI? Not sure exact syntax could someone explain me that if I want to match in permissions.allow if a phone 10.10.10.10 dial(r-uri) 1234 allow it and everything else is blocked? What is the preference does kamailio check for permissions.deny first if there is no matching then checks permissions.allow? Thanks in advance, Asim

What I wanted to say is that kamailio does not reply 481. So the problem is in the responder of requests sent by UAC and forwarded by Kamailio. Somehow, the dialog is destroyed before the BYE (or other in-dialog request) is sent by UAS. If you can grab the SIP trace of such call (e.g., using ngrep on kamailio server), I can give more hits (try to select the sip flow for one such call only, sending full sip trace will be too big).

This is a minor release, bringing only fixes to the code. So upgrading from 3.0.0 or 3.0.1 to 3.0.2 is exactly what you said, just recompile and reinstall modules and core, keep the rest in place.

could not bind to the TM-Module
by Javier Menendez 25 May '10

25 May '10

Hi, I have been configuring an Kamailio 3.0.1, with the dispatcher module. Everything seems to work just fine but when a gateway is in Probing mode it remains in that state for ever. checking the logs I found some weird messages, I think that is the rrot cause of the problem but I have no clue how to solve it. These are the messages I mentioned before May 21 14:56:34 localhost /usr/local/sbin/kamailio[21539]: DEBUG: <core> [sr_module.c:516]: find_export_record: <load_tm> not found May 21 14:56:34 localhost /usr/local/sbin/kamailio[21539]: WARNING: dispatcher [dispatcher.c:358]: could not bind to the TM-Module, automatic re-activation disabled.

no Contact in REFER generated with dlg_bridge
by Anton Roman 25 May '10

25 May '10

Hi all, I'm trying to implement a Click2Dial service by using the dlg_bridge command from the dialog module. Although it works in this case, I found two problems in the scenario and I would like to read your opinion about them. 1) Fisrt problem: the REFER generated by Kamailio doesn't contain a contact header. As per RFC 3515, this request should have a Contact header. This REFER is not being accepted by a proprietary device. This is can be worked around with the append_hf() command from the textops module, but I don know if it is a good solution. 2) The second one arises when the ACK generated by Kamailio, goes through Kamailio (caller and calle involved in click2dial are registered on the Kamailio server): the branch of the second via header is not correctly populated. Its content is '0' when it must be tha same as in the INVITE. Below you can find the traces of the whole scenario. Could you take a look at them and give me your feedback?

sipp and stateful transaction problem
by JR Richardson 25 May '10

25 May '10

Hi All, I'm doing some testing with kamailio 1.5: kamailio1:/etc/kamailio# kamailio -V version: kamailio 1.5.4-notls (i386/linux) flags: STATISTICS, USE_IPV6, USE_TCP, DISABLE_NAGLE, USE_MCAST, SHM_MMAP, PKG_MALLOC, F_MALLOC, FAST_LOCK-ADAPTIVE_WAIT ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535, PKG_SIZE 4194304 poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. svnrevision: 2:6005M @(#) $Id: main.c 5608 2009-02-13 16:48:17Z henningw $ main.c compiled on 10:14:11 May 18 2010 with gcc 4.3.2 Using dispatcher module trying to load balance SIP calls across some Asterisk servers. I have it working fine when I test in this scenario: sip phone dial out><asterisk><kamailio><round robin to several asterisk servers This works stateful and stateless, handles everything gracefully. This scenario is giving me fits: sipp dial out><kamailio><round robin to several asterisk servers I get retransmits on every call back to sipp with errors like "Discarding message which can't be mapped to a known SIPp call" and "SIP/2.0 481 Call leg/transaction does not exist" This happens with kamailio setup stateful or stateless. I'm wondering if sipp is the problem or just doesn't play well with kamailio? I've kept the config as simple as possible for testing, it is listed here http://pastebin.com/BZ8hJvJv Here is my sipp usage: sipp -sn uac 10.10.12.53 -i 10.10.14.97 -s 55 -d 7000 -l 10 -r 1 -trace_err Any insight would be appriciated. Thanks. JR -- JR Richardson Engineering for the Masses

Need help with route statement

Hi all... Well I have made some progress... Bellow is my routing statement: route{ if (!mf_process_maxfwd_header("10")) { sl_send_reply("483","Too Many Hops"); break; }; if (msg:len >= 2048 ) { sl_send_reply("513", "Message too big"); break; }; if (!method=="REGISTER") record_route(); if (loose_route()) { append_hf("P-hint: rr-enforced\r\n"); route(1); break; }; if (!uri==myself) { append_hf("P-hint: outbound\r\n"); route(1); break; }; if (uri==myself) { if (method=="REGISTER") { save("location"); break; }; lookup("aliases"); if (!uri==myself) { append_hf("P-hint: outbound alias\r\n"); route(1); break; }; }; append_hf("P-hint: usrloc applied\r\n"); route(1); } route[1] { if (src_ip==10.98.6.5) { if (dst_port==5065) { t_relay_to_tcp("10.98.118.20", "5065"); } else if (dst_port==5066) { t_relay_to_tcp("10.98.118.20", "5066"); } else if (dst_port==5067) { t_relay_to_tcp("10.98.118.20", "5067"); } else { t_relay_to_tcp("10.98.118.20", "5060"); } } else { t_relay_to_udp("10.98.6.5", "5060"); }; } When asterisk sends a call to kamailio, Kamailio then sends the invite to 10.98.118.20 via TCP on port 5061.

Add Header on cancel
by Alex Rendour 21 May '10

21 May '10

Hi, Is it possible to add an header reason in a cancel? We receive a CANCEL without header reason and we need to forward to another SIP proxy with the reason header? We use this code in my conf: if(is_method("CANCEL")) { if(!is_present_hf("Reason:")) { xlog("L_ERR", "reason missing"); append_hf("reason: Q.850; cause=31\r\n"); xlog("L_ERR", "add raison"); } } Thanks, regards, -- Alexandre Rendour Acropolis Telecom <http://www.acropolistelecom.net> Direct: +33 (0) 181813201 Support: +33 (0) 811 851 851 rendour(a)acropolistelecom.net <mailto:rendour@acropolistelecom.net> Adresse : 161-163 avenue Gallieni Paris - Porte de Bagnolet 93170 Bagnolet

Need help in routing configuration
by Nelson Pereira 20 May '10

20 May '10

I have the bellow setup for openser, yet this wont work in Kamilio. Wondering if anyone could help to make this routing code work? What Im looking to do is receive Invites in UDP and relaying it via TCP.... route{ if (!mf_process_maxfwd_header("10")) { sl_send_reply("483","Too Many Hops"); exit; }; if (msg:len >= 2048 ) { sl_send_reply("513", "Message too big"); exit; }; if (loose_route()) { append_hf("P-hint: rr-enforced\r\n"); route(1); }; if (!uri==myself) { append_hf("P-hint: outbound\r\n"); route(1); }; route(1); } route[1] { if (src_ip==10.98.6.5) { if (dst_port==5060) { t_relay("tcp:10.98.118.20:5060"); } if (dst_port==5065) { t_relay("tcp:10.98.118.20:5065"); } else if (dst_port==5066) { t_relay("tcp:10.98.118.20:5066"); } else if (dst_port==5067) { t_relay("tcp:10.98.118.20:5067"); } # else { # t_relay("tcp:10.98.118.20:5060"); # } } else { t_relay("udp:10.98.6.5:5060"); }; } Nelson Pereira Senior Network Specialist Protus<http://www.protus.com/> npereira(a)protus.com<mailto:name@protus.com> phone: 613.733.0000 ext.528 MyFax: 613.822.5083 MyFax.com<http://www.myfax.com/> | my1voice.com<http://www.my1voice.com/> | Campaigner.com<http://www.campaigner.com/>

allow_trusted() use.
by Vicente 20 May '10

20 May '10

Good afternoon, I'm trying to configure permissions module to allow calls from an IP address. I've the module loaded, the entry on the data base table trusted. But according to the examples I've seen on the list and other sources, the call to allow_trusted() has to be placed just before the INVITE authorization section like: if (is_from_local()){ if(!allow_trusted()){ ...authorization... In my scenario allow_tusted() is never reached and thus Kamailo allows the call regardless the table trusted is populated with the the allowed proxy IP or not. The INVITEs that I want to allow come from another proxy and then I understand is_from_local() is always evaluated false for those messages. And allow_trusted isn't reached. Where on the script should the condition to allow only the calls from the external proxy IP be placed? Thanks in advance. Vicente.

Routing problem
by alet＠librelogiciel.com 19 May '10

19 May '10

Hi, First I'm a complete SIP newbie. We've purchased a new pabx which is a complete piece of crap (Alcatel OmniPCX OXO) : no LDAP support, no registrar functionnality, and so on... and it seems there's no way to upgrade. This pabx is on a subnet different from the one used by desktop computers. What I'd like to achieve is to be able to install SIP soft phones onto desktop computers (like ekiga for example), allow them to call all non-IP phones already configured in the pabx, and be called by any non-IP phone through the pabx. Since the pabx doesn't have a registrar mode, it can't associate IP addresses with phone numbers. So in ekiga, I can configure the pabx as a SIP proxy, and my ekiga can call any normal (non-IP) phone connected to the pabx. This works fine, but is only one half of what I want, since I want these SIP phones to be callable from non-IP phones. Enters openser, which I plan to use as a registrar and router. So I've installed openser 1.3.2 onto a Debian Squeeze box. I can successfully register SIP soft phones to it, and they can call each other just fine calling (number(a)sip.example.com). This openser box is on the same subnet as the Alcatel pabx (so different from the one used by SIP soft phones). All our "normal" phone numbers are 6 digits long and begin with 290, so I want to route all call numbers beginning with "290" to the Alcatel pabx. So I've modified the default openser.cfg to contain : --- CUT --- port=5060 listen=udp:10.125.0.1:5060 ... route { ... if (is_method("INVITE")) { setflag(1); if (uri=~"sip:290[0-9]{3}@sip.example.com") { xlog("#### CALL TO NON-IP PHONE ####\n"); route(2); } } ... } ... # route[1] was in original openser.cfg route[1] { # for INVITEs enable some additional helper routes if (is_method("INVITE")) { t_on_branch("2"); t_on_reply("2"); t_on_failure("1"); } if (!t_relay()) { sl_reply_error(); }; exit; } # # I've added the following route[2] { rewritehostport("pabx-alcatel.example.com:5060"); xlog("#### Server and port rewritten ####\n"); route(1); }... --- CUT --- Now in ekiga if I dial sip:number@pabx-alcatel.example.com:5060 it works fine as it always did, because this call is direct. However if I dial sip:number@sip.example.com:5060 the host and port in URL are correctly rewritten in sip:number@pabx-alcatel.example.com:5060 but nothing happens : the call doesn't ring and fails immediately. In the logs when dialing sip:290081@sip.example.com:5060 I've got this, so I suppose it *SHOULD* work : --- CUT --- /usr/sbin/openser[759]: #### CALL TO NON-IP PHONE #### /usr/sbin/openser[759]: #### Server and port rewritten #### /usr/sbin/openser[759]: new branch at sip:290081@pabx-alcatel.example.com:5060 /usr/sbin/openser[760]: incoming reply /usr/sbin/openser[758]: incoming reply --- CUT --- but it doesn't work as expected. any idea why ? NB : I understand this would only solve half of my problem, the other part will be solved (I hope) with the help of the guy who installed the pabx. Thanks in advance Jerome Alet

Siremis - missing cdr calcs and repeats
by Anders 19 May '10

19 May '10

Hi, I'm having some challenges with Siremis, and it says on the project website that this list is the place to ask - so here are the two issues: 1. Repeats: I had problems with repeats in the cdrs table. This was possible, because I had forgotten to set the correct unique index (call_id + from_tag + to_tag). Once this was set, it was obviously not possible to make the repeats anymore - so problem solved. But I still wonder: why was it trying to calculate calls that had already been calculated? Shouldn't it ignore these and only treat new ones? 2. Missing calcs After an unsuccessful attempt to upgrade MySql from 5.0 to 5.1, it seems that not all calls are being calculated and put in the cdrs table. The CRON job was stopped due to the failed upgrade of MySql, but I started it again later - MySql was not down. However, I thought it would 'catch up' with the transaction that had not been calculated while the CRON job for the stored procedure had been off, but it did not. In fact, it seems that not all calls are being calculated and put inthe cdrs table - I'm missing almost half the calls. Any idea what this can be? Thanks!! //Anders

Kamailio 1.5 stops processing messages
by Santiago Gimeno 19 May '10

19 May '10

Hi, I'm working with Kamailio 1.5 (rev 5968) and from time to time kamailio freezes and stops processing messages. Kamailio is working only in UDP. I really don't know in which conditions this problem is happening: it happens both in high and low load. Here is a backtrace of one of the UDP working processes when kamailio is frozen (all the other UDP process backtraces look similar) : #0 0xb7fdf410 in ?? () #1 0xbfbfec28 in ?? () #2 0x00000001 in ??

Trying to find the built-in password for the database....
by SIP 18 May '10

18 May '10

So... I've been working on installing Kamailio 3.0.1 on a test server to begin migration from SER 0.9.6 (yes, I know it will be a bit of a migration). The INSTALL docs are... not perfect if working with the source (and not a package). Following the instructions did not get me mysql support. There were files that didn't install where they needed to be that I had to move over by hand -- none of which is mentioned in the docs. Even after removing the db_mysql from the list of excluded modules, it BUILT the module, but didn't install it. I also used a different DB name, username, and password from the default (to match more closely the environment we'll be migrating from). After tinkering, I got the DB scripts to run with the right username/pass, and have now edited the kamctlrc and kamailio.cfg to have the proper db name, username, pass, etc. However, when I try and start kamailio, it fails, and the log spits out a bunch of access denied messages using the original, default username/pass (openserro@localhost). My question is, where is that password located? What file have I missed? N.

Hello. Is possible use some module in kamailio to authenticate against a Asterisk Box for example?.

lookup(), received an $du
by Andreas Granig 13 May '10

13 May '10

Hi, Some interesting behavior with kam-3.0, which I haven't experienced with <= 1.5: Let's say I have two subscribers A and B registered. A has a received-value in location table, B has it set to NULL. If I call lookup() for A, $ru is set to the registered contact, and $du is set to the received-value. When for example A is busy, I catch it with a failure route and rewrite $ru to B. Calling lookup() again sets my $ru to the contact of B, but since the received-value of B is NULL in the DB, the $du is still pointing to the received-value of A, instead of being set to null. A quick-fix is to set $du to null before calling lookup(), but I'm wondering if this is a bug or intended behavior? Thanks, Andreas

No problem. It is all courtesy of my friend 'grep', which has following options: -H print filename -R search recursively -i case-insensitive matching So, for example, one can do something like this using 'egrep', a variant of grep that supports regular expressions: egrep -HRi ".*bind.*db.*" .

Configuring TCP keep alive and connection lifetime
by Pascal Maugeri 11 May '10

11 May '10

"kamailio" <users(a)lists.kamailio.org>, Hi I am sorry to ask again about this topic but I don't understand yet how the TCP keep-alive are sent. With Kamailio 3.0.1 and the following configuration: tcp_keepalive=yes tcp_keepidle=10 tcp_connection_lifetime=3600 The TCP connection is kept alive and TCP Keep-Alive packets are sent when the TCP connection is idle. But I don't understand why the time between KA is not linear: first KA is sent 10 seconds after last last TCP message. This is logical and connected with the tcp_keepidle=10 configuration. then 2nd KA is sent 75 seconds after first KA Then my client sends some traffic and 23 seconds after last message, a new KA is sent. Another time it was 54 seconds. etc. etc. Could you explain me where do come from these values of 75 seconds, 23, 54 ? Everything works well: my client behind NAT is kept connected but I'd like to understand why it does work :-) Thanks in advance, Pascal

Wrong handling CANCEL message
by pars3c 08 May '10

08 May '10

Hi, i have a problem about the handling of the "cancel" message. The call flow is this: A -----------------> (Invite) Proxy (P) B (100 Tryng) <--------------------------- ----------------->(Invite) B (100 Tryng) <--------------------------- (183 Progress) <--------------------------- (183 Progress) <--------------------------- (200 OK) <--------------------------- (200 OK) <--------------------------- --------------------------------->(CANCEL) (200 canceling) <--------------------------- (200 OK) <--------------------------- (200 OK) <--------------------------- ----------------->(ACK) ----------------->(ACK) (BYE) <--------------------------- (BYE) <--------------------------- ----------------->(481 Call Leg/Transaction Does Not Exist) ----------------->(481 Call Leg/Transaction Does Not Exist) The B side answer with OK, after a while , a send a CANCEL. I don't know why Kamailio don't forward this message to the B side. B retry to send the OK message, then A send the ACK. At the end , B send BYE , but A don't have the transactin. In this situation, kamailio should deliver the "CANCEL" to the B side ? (even if, before B send the OK ) Or the proxy should not consider the CANCEL because B has answered with "OK" ?

auth_db authorize realm
by Alex Balashov 06 May '10

06 May '10

There is a peculiar and confusing aspect to the documented significance of the "realm" argument to www_authorize(), and presumably proxy_authorize() as well. The documentation says that if this value is empty, the digest realm will be generated from the domain part of the To or From URI, whichever is applicable to the given situation (REGISTER vs. any other request). This is the way *_authorize() is invoked in most cases, and works fine. However, we recently ran into a situation where www_authorize() would always fail and claim that it could not find the user in 'subscriber' despite being provided correct username and domain, with the appropriate options -- return value -1. We were sending the public host IP as the domain of the To URI, using it as the realm, and setting it in the domain column of the 'subscriber' table. The problem was, the public IP of the host was not in /etc/hosts -- /etc/hosts consisted solely of: 127.0.0.1 localhost.localdomain localhost For some reason, it wasn't until I added the public IP into it that www_authorize() started working properly: 127.0.0.1 localhost.localdomain xxx.xxx.xxx.xxx public_host.domain.tld public_host I don't see anything different in the anatomy of the 401 Unauthorized challenges; the realm is still xxx.xxx.xxx.xxx in both cases. It just seems that unless Kamailio detects a DNS reverse alias for the domain, it won't properly authenticate requests. This aspect of the behaviour is not documented, and I am also confused as to why it happens this way. Any clarification would be appreciated. -- Alex Balashov - Principal Evariste Systems LLC 1170 Peachtree Street 12th Floor, Suite 1200 Atlanta, GA 30309 Tel: +1-678-954-0670 Fax: +1-404-961-1892 Web: http://www.evaristesys.com/

segfault kamailio 3.01 avp_copy flag g
by Jon Bonilla 06 May '10

06 May '10

Hi all I have experienced segfaults when using avp_copy in Kamailio 3.01. This happens when using the "g" flag and the avp is not null (no problem if it has no content) avp_copy("$avp(s:block_out_list)", "$avp(s:caller_block_out_list)/gd"); Removing the "g" flags works ok (but does not copy all the content of course): avp_copy("$avp(s:block_out_list)", "$avp(s:caller_block_out_list)/d"); Directly copying the avp works fine: $avp(s:caller_block_out_list) = $avp(s:block_out_list); Logs: kernel: [1503237.523015] kamailio[8156]: segfault at 1008eb91c ip 505344 sp 7fffffffad10 error 4 in kamailio[400000+1c9000] WARNING: <core> [usr_avp.c:483]:AVP specified with index, but not used for search ALERT: <core> [main.c:722]: child process 8156 exited by a signal 11 ALERT: <core> [main.c:725]: core was not generated INFO: <core> [main.c:737]: INFO: terminating due to SIGCHLD INFO: <core> [main.c:788]: INFO: signal 15 received

RPID Mod Question
by dotnetdub 06 May '10

06 May '10

Hi List, For certain Asterisk customers I want them to be allowed to manage and send their own CLI - we currently pass this onto providers as RPID. For example we also run a multi tenant pbx that uses kamailio as its proxy so it makes sense that we can send the callerID from this box to kamailio. Basically I will setup a prefix, check for that and if it matches I want to rewrite the RPID using the From"" from the SIP message.. From: "16172345671" <sip:username@domain>;tag=xxxxxxxxxxxx In this case I would send the RPID as <sip:16172345671@domain;party=calling;id-type=subscriber;privacy=off;screen=yes>" to our providers rather than reading the default value from the database for rpid. Where in the Kamailio / SR docs should I be looking for examples that would be similar / manipulating this type of info. Thanks, S.

Kamailio SCTP support
by Francisco José Méndez Cirera 05 May '10

05 May '10

Hello, I've downloaded Kamailio 3.0.0 (the last release) and I´ve seen it´s possible downloading a "binary tar.gz" or the source to compile directly. I would like to know if the binary has enabled support for SCTP by default. If it´s enabled by default, how can I activate it (I can´t find any option related to sctp in kamailio.cfg) ? If it isn´t enabled by default, which are the dependencies? Is there a document or something with at least the main dependencies? Thank you very much. Bye!

new features: extended cfg preprocessor directives
by Daniel-Constantin Mierla 05 May '10

05 May '10

Hello, just to let you know about some new features related to config preprocessing. 3.0 added config preprocessor directives such as 'include_file' and 'define'. But the define could be used only to control which parts of config file are active. Several days ago I committed the code to allow you 'define' values for IDs, like: #!define MYINT 123 #!define MYSTR "xyz" The defined IDs are replaced at startup, during config parsing, e.g.,: $var(x) = 100 + MYINT; - is read as: $var(x) = 100 + 123; Moreover, you can have multi-line defined IDs: #!define IDLOOP $var(i) = 0; \ while($var(i)<5) { \ xlog("++++ $var(i)\n"); \ $var(i) = $var(i) + 1; \ } - then in routing block route { ... IDLOOP ... } A completely new thing is the substitution preprocessor directive: #!subst "/regexp/subst/" Defined IDs are not replaced within string values (because a cfg IDs is a standalone alphanumeric token, not enclosed in single or double quotes), so if you need to change something inside a string within config file, then use substitution. For example, if you want to replace the password in all db_url module parameters: #!subst "/DBPASSWD/xyz/" modparam("acc", "db_url", "mysql://user:DBPASSWD@localhost/db") modparam("auth_db", "db_url", "mysql://user:DBPASSWD@localhost/db") The value of a 'subst' directive can be any valid perl-like substitution expression, you can use wildcards, group tokens, backreferences, .... Hope this will make your cfg scripting easier. Testing and feedback is appreciated.

Simple Trunkig with Kamailio
by Jared Martin 05 May '10

05 May '10

Ok, this is probably an easy question: Say I have my kamailio server set up and all of my voip clients are gleefully calling each other... but now I want to connect them to the PSTN. Can I set up kamailo to trunk calls using a few grandstream gateways? or is Asterisk neccesary? Sorry if the answers out there, but I haven't found anything that answered the question directly. I'm a linux admin, but I'm new to PBX's and the like. I've installed kamailio in the past using instructions specific to that situation, but haven't configured trunking (or I didn't recognize thats what it was) references to howtos or tutorials would also be greatly appreciated Thanks for your help, Jared Martin

kamailio and presence_xml parse error
by Francesco 05 May '10

05 May '10

Hi to all. I'm new here. I'm getting crazy with presence_xml error. I'm using kamailio 1.5.4 notls with xlite 3.0 (winXP client) softphone and postgresql 8.4 as db backend. Seems that presence works, but i have error in parsing xml: those are the relevant log: Apr 29 16:42:54 ocs /usr/sbin/kamailio[2462]: INFO:presence:send_notify_request: NOTIFY sip:user1@ocs.ita.domain.net<sip%3Auser1(a)ocs.ita.domain.net>via sip:user1@10.44.17.145:24258 on behalf of sip:user2@ocs.ita.domain.net<sip%3Auser2(a)ocs.ita.domain.net>for event presence Apr 29 16:42:54 ocs /usr/sbin/kamailio[2463]: ERROR:presence_xml:agregate_xmls: while parsing xml body message Apr 29 16:42:54 ocs /usr/sbin/kamailio[2463]: ERROR:presence_xml:pres_agg_nbody: while aggregating body When i login on kamailio, the users are not immediatly notified to my presence...but, when there's a change of status, the client are notified and on softphone the status change. Other that, if the client close softphone, i can watch this on the log: Apr 29 16:42:41 ocs /usr/sbin/kamailio[2461]: ERROR:presence_xml:offline_nbody: while parsing xml memory Apr 29 16:42:41 ocs /usr/sbin/kamailio[2461]: ERROR:presence_xml:pres_agg_nbody: while constructing offline body Apr 29 16:42:41 ocs /usr/sbin/kamailio[2461]: INFO:presence:send_notify_request: NOTIFY sip:user1@ocs.ita.domain.net<sip%3Auser1(a)ocs.ita.domain.net>via sip:user1@10.44.17.145:24258 on behalf of sip:user3@ocs.ita.domain.net<sip%3Auser3(a)ocs.ita.domain.net>for event presence And the client, on the other softphone, results on line, rather then offline. I'm thinking about encoding database, i've tryied with SQL ASCII and UTF-8 too. Same behaviour. I try different releases (1.5.3 no tls) on different distribution (debian, lucid, alpine linux). Same behaviour. Obiouvsly, the softphone are right configured (presence agent is enabled). Any hints?

Our intention was to make also the authentication against LDAP. After some research, we've seen there's no specific module for SER to work with LDAP and we have considered some alternatives among them there was the "module" from ETH world<http://www.ethworld.ethz.ch/technologies/sipeth/ser_modules/ldap>. However, we didn't manage to make it work (if it's an advisable choice we'd appreciate some clues). So, we decided to make the authentication through the RADIUS server. Nevertheless, we are having some problems with the way data is sent. When doing the user authentication there's no problem as it is sent in plain text and we modified to do it against the email attribute as it's this what we want. It makes it perfectly. But it turns out that when we try to make the password authentication, as the data sent from SER comes in a hash (user:realm:password) as long as we know, we don't really know how to make it compare with the password field in LDAP (under MD5 algorithm as well). When we make a test over Radius by sending plain text it works perfectly so it shouldn't be a problem by searching the attributes over LDAP. We have tried to follow instructions to set the digest section properly but there's something we definitely miss.

Nevertheless, we are having some problems with the way data is sent. When doing the user authentication there's no problem as it is sent in plain text and we modified to do it against the email attribute as it's this what we want. It makes it perfectly. But it turns out that when we try to make the password authentication, as the data sent from SER comes in a hash (user:realm:password) as long as we know, we don't really know how to make it compare with the password field in LDAP (under MD5 algorithm as well). When we make a test over Radius by sending plain text it works perfectly so it shouldn't be a problem by searching the attributes over LDAP. We have tried to follow instructions to set the digest section properly but there's something we definitely miss. Attached there's a log from the radius when trying to log with SER and the Register section from SER. log: 03 User-Name = "my.user(a)i2cat.net" Digest-Attributes = 0x0a0b7061626c6f2e726f73 Digest-Attributes = 0x010b69326361742e6e6574 Digest-Attributes = 0x022a34626466643065343837303734363630626261366134363437663730313034343639663532306532 Digest-Attributes = 0x040f7369703a69326361742e6e6574 Digest-Attributes = 0x030a5245474953544552 Digest-Response = "6c95bcba1fca30e976fa9295025b1bf4" Service-Type = Sip-Session Sip-Uri-User = "my.user" NAS-Port = 5060 NAS-IP-Address = 127.0.0.1 +- entering group authorize ++[preprocess] returns ok ++[chap] returns noop ++[mschap] returns noop rlm_digest: Adding Auth-Type = DIGEST ++[digest] returns ok rlm_realm: Looking up realm "i2cat.net" for User-Name = " my.user(a)i2cat.net" rlm_realm: No such realm "i2cat.net" ++[suffix] returns noop rlm_eap: No EAP-Message, not doing EAP ++[eap] returns noop ++[unix] returns notfound ++[files] returns noop rlm_ldap: - authorize rlm_ldap: performing user authorization for my.user(a)i2cat.net WARNING: Deprecated conditional expansion ":-".

NAT Traversal IPTel example
by Andy Savage 05 May '10

05 May '10

Hi there, I've been setting up SER for a testing server on the local network behind a NAT. I'm having problems understanding how to setup the NAT routing in the configuration file. My understanding is that IPTel has already setup advanced NAT routing on the free service (as per the website). Is it possible to get a copy of the configuration file (atleast the part that has the NAT routing stuff). This would help me immensely in getting proper nat traversal setup as it already works great on the IPTel server. Not sure who I would contact in regards to this, but this seemed like a good place to start.

RTPproxy in bridge mode question
by Uriel Rozenbaum 04 May '10

04 May '10

Guys, I'm successfully using a Kamailio + RTPproxy setup in bridge mode with most of my Gateways. My setup includes two different interfaces one with a public IP and teh other with the private IP. Now I'm facing some slight issue. Some providers won't accept my calls (or calls will have some strange behavior) if the Contact header has an IP out of immediate range. I tried to use fix_nated_contact() function but as per my topology, this function will not change the contact header because the IP is already the one on the interface. Example: U 192.168.200.X:5060 -> 192.168.200.Y:5060 INVITE sip:111160911097@192.168.200.Y SIP/2.0. Via: SIP/2.0/UDP 192.168.200.X:5060;branch=z9hG4bK096baacc;rport. From: "Uriel Rozenbaum" <sip:60911100@192.168.200.X>;tag=as32794d5e. To: <sip:111160911097@192.168.200.Y>. Contact: <sip:60911100@*192.168.200.X*>. U 200.A.A.A:5060 -> 200.B.B.B:5060 INVITE sip:898960911097@200.B.B.B SIP/2.0. Record-Route: <sip:200.A.A.A;r2=on;lr=on;ftag=as32794d5e>. Record-Route: <sip:192.168.200.Y;r2=on;lr=on;ftag=as32794d5e>. Via: SIP/2.0/UDP 200.A.A.A;branch=z9hG4bK5222.14fbf4f7.0. Via: SIP/2.0/UDP 192.168.200.X:5060;received=192.168.200.X;branch=z9hG4bK096baacc;rport=5060. From: "Uriel Rozenbaum" <sip:60911100@192.168.200.X>;tag=as32794d5e. To: <sip:111160911097@192.168.200.Y>. Contact: <sip:60911100@*192.168.200.X*>. Is there any way to let know Kamailio the outgoing IP I'll be using and fix the contact accordingly? I can trigger this change after I know the destination IP. Thanks! Uriel

Hi, We need to add header on the failure route.

Simple Trunking with Kamailio
by Jared Martin 01 May '10

01 May '10

Ok, this is probably an easy question: Say I have my kamailio server set up and all of my voip clients are gleefully calling each other... but now I want to connect them to the PSTN. Can I set up kamailo to trunk calls using a few grandstream gateways? or is Asterisk neccesary? Sorry if the answers out there, but I haven't found anything that answered the question directly. I'm a linux admin, but I'm new to PBX's and the like. I've installed kamailio in the past using instructions specific to that situation, but haven't configured trunking (or I didn't recognize thats what it was) references to howtos or tutorials would also be greatly appreciated Thanks for your help, Jared Martin

sr-users = ser + kamailio users mailing lists
by Daniel-Constantin Mierla 30 Apr '10

30 Apr '10

Hello, a short note that the merging of SIP Express Routers (SER) users mailing list into sr-users is completed from subscriber point of view: - posts to serusers(a)lists.iptel.org are directed to sr-users(a)lists.sip-router.org - posts to sr-users(a)lists.sip-router.org are received by subscribers of serusers(a)lists.iptel.org Just a bit of time ago, kamailio (openser) users' mailing list was merged as well. Since the release 3.0.x is practically the same source code, no mater the binary is compiled as ser or kamailio, and the development is in the same place (code in same repository), a combined mailing lists environment is the right for providing the best answers in shortest time for both communities. Therefore, now there are two mailing lists: - sr-users(a)lists.sip-router.org - to be used for discussions about stable versions and generic project/community topics - sr-dev(a)lists.sip-router.org - to be used for discussions about devel version and future development topics If you were subscribed to both with same email address, you won't get duplicates. If you had some settings that are no longer in place, please contact one of devels on sr-dev lists or write to me.

Bug with avp's or feature ?
by Tristan Mahé 30 Apr '10

30 Apr '10

Hi guys, I was debugging an install on kamailio 3.0, and was asked to add per user custom outbound proxies. To do so, I used load_credentials from auth_db to store the custom route in an avp, as you can see in the relevant part below. I noticed a strange thing, POINT 1 show "OK", but POINT 2 shows "KO". Is it a normal behaviour that avp got deleted after the Dialog PART ? Regards, Gled --------------------------------------------------------------------------------- modparam("auth_db", "load_credentials", "$avp(s:proxy)=outbound_override;$avp(s:rights)=rights;$avp(s:max_out)=max_out") route[INVITE_FROM_UAC] { if (!www_authorize("", "my_user_view")) { www_challenge("", "1"); } if ( !($tU =~ $avp(s:rights_ereg)) ) { sl_send_reply("403","Forbidden"); t_release(); exit(); } /* POINT 1 */ if ( is_avp_set("$avp(s:proxy)") ) { xlog("OK"); } else { xlog("KO"); } get_profile_size("outbound","$fU","$avp(calls_out)"); if ( $avp(s:max_out) != 0 && $avp(calls_out) >= $avp(s:max_out) ) { t_reply("403","Too Many calls"); t_release(); exit(); } /* Dialog PART */ if (!is_in_profile("outbound")) { dlg_manage(); set_dlg_profile("outbound","$fU"); } /* POINT 2 */ if ( is_avp_set("$avp(s:proxy)") ) { xlog("OK"); } else { xlog("KO"); } } ---------------------------------------------------------------------------------

[Kamailio-Users] Exotic case (but real) in which RtpProxy doesn't work
by Iñaki Baz Castillo 28 Apr '10

28 Apr '10

Hi, I've a problem with an Alcatel PBX in the way it performs transference: - Alcatel (behind NAT) sends INVITE to 111 and Kamailio forces RtpProxy. Let's assume the selected UDP port for RtpProxy is 1000. - Alcatel sends INVITE to 222 and Kamailio forces RtpProxy. Let's assume the selected UDP port for RtpProxy is 2000. Then Alcatel performs the transference as follows: - It sends a re-INVITE for 111 to Kamailio by setting the SDP to the IP or RtpProxy and port 2000. - It also sends a re-INVITE for 222 to Kamailio by setting the SDP to the IP or RtpProxy and port 1000. This is, Alcatel wants that the provider (me) sends the RTP to itself, while mantaining the original SIP dialogs established (so it's ok at signalling level, but at RTP level it cannot work as RtpProxy shoud send RTP to itself). I'm thinking on how to solve it but find no solution. Any suggestion? Thanks. -- Iñaki Baz Castillo <ibc(a)aliax.net>

[permissions] 'address' table and mask priorirty
by Iñaki Baz Castillo 28 Apr '10

28 Apr '10

Hi, some time ago I asked if allow_source_address_group() gives preference to the entries in 'address' table with lowest mask. I was replied that such case is not analyzed. But the fact is that in my tests it just works: Entry 1: - grp = 1 - ip_addr = 9.9.9.9 - mask = 32 Entry 2: - grp = 2 - ip_addr = 9.9.9.0 - mask = 24 I send a request from IP 9.9.9.9 and the function allow_source_address_group() always returns "1", it doesn't matter if the entry 1 appears before or after the entry 2, neither their "id" value. So it works as I expected (even if it's not explained in the documentation). However after checking the module code it seems that there are just two cases: - IP addresses (mask = 32). - Subnets (mask != 32). So first the source address is always matched against he address hash, and if it doesn't match then it is matched against the subnet hash, but in this last case it is not taken into account any kind of priority based on mask value, am I right? Could somebody confirm it please? Thanks. -- Iñaki Baz Castillo <ibc(a)aliax.net>

[LCR openser 1.2] Strange behavior in "lcr" table
by Iñaki Baz Castillo 28 Apr '10

28 Apr '10

Hi, I have configured LCR in an existing OpenSER 1.2 installation by filling the "lcr" table as follows: id prefix from_uri grp_id priority 1 NULL NULL 1 1 2 NULL NULL 2 2 In "gw" table there are some entries with "grp_id=1" and some others with "grp_id=2". Then in the script I just call "load_gws()" as usual, expecting that first is ALWAYS selected a gateway with grp_id=1. In fact I have ths *same* configuration working as expected in Kamailio 1.5. But for some reason, in OpenSer 1.2 for some calls "load_gws()" selects gateways with "grp_id=2", which IMHO doesn't make sense at all as grp_id 2 has priority 2 and its gateways would be selected always after those belonging to grp_id 1. Is there any bug or different behavior in LCR in openser 1.2? or do I miss something? Thanks. -- Iñaki Baz Castillo <ibc(a)aliax.net>

termination with user/pwd
by Anders 27 Apr '10

27 Apr '10

I'm sure this has been asked before, but I couldn't find the answer anywhere when I googled it. I have a temporary situation where I need to terminate calls to a carrier with user/pwd authentication, and not through the IP authentication. As I understand it this is not a normal setup situation for a gw in Kamailio - but is there a way I can do this? Thanks, Anders

Sintax errors can stop the machine?
by Bruno Machado 26 Apr '10

26 Apr '10

We are facing a periodically problem with a server that is running Kamailio 1.5.2. I think that it is not the case, but I will ask anyway. Some clients, sometimes, send us messages with sintax errors. This machine needs to be rebooted every week. It stops working completely. I don't think that SIP messages with this kind of errors can lead the machine to its 'death'. This proxy is very simple: it just receives and forwards the calls to pstn carriers. The routing rules are defined in the script, so we dont use modules to take the IPs and all other information about the carriers. The database is used just for ACC. Nothing more. Also, it is not receiving a flood atack. We have several servers running at this time with a huge number of clients and we never had this problem. This machine is the only one that does not want to work without a weekly break :) The causes, in my opnion, will be with the operational system or something physical. But, I would like to know if somebody already saw this behavior with SIP messages. tks a lot bruno machado

B2BUA removing a=nortpproxy:yes (rtpproxy-1 <---RTP---> rtpproxy-2)
by Iñaki Baz Castillo 26 Apr '10

26 Apr '10

Hi, I must deal with a B2BUA which keeps the original SDP unchanged except the fact that it removes the "a=nortpproxy:yes" line added by RtpProxy. The B2BUA intercommunicates two Kamailio, both forcing its own RtpProxy server. I've not tested it again but expect there will be no RTP as each RtpProxy will wait for RTP coming from the other. Am I right? Of course I could force RtpProxy just in NAT cases and so, but I prefer to force it always so the clients of each Kamailio can configure QoS for the media addresses (different in each server). Is there some workaround for it? In the other hand: is it possible two different Kamailio's to share the same RtpProxy server? I've never tryied it. If it's valid, would it solve the B2BUA issue? (I don't think so as there are still different media sessions created by different kamailio instances). Any thought? Thanks a lot. -- Iñaki Baz Castillo <ibc(a)aliax.net>

Re-invite problems with t.38?
by Espen Berg 26 Apr '10

26 Apr '10

Hello all! I finally have something that I could call a working config (almost that is), the proxy works fine with voice and fax sent over g.711 (but I guess re-invites will cause problems in this scenario also). The problem occurs when I try to switch to T.38. Since it works with voice my guess is that the problem is caused by the re-invite to t.38. I guess it has to be solved by a if (loose_route()) section, but I am little bit clueless right now, I have tried multiple variants but with no success. RTP proxy is started with the -l flag to distinguish between local and public traffic. -l PUBLIC.IP.ETH0/LOCAL.IP.ETH1 The setup: Sonus UAC/Trunk <-private ip-> (eth1)Kamailio/RTPProxy(eth0) <-public ip-> Asterisk IP.TO.TRUNK = Sonus IP, public address range, but only reachable by private net (from the range of LOCAL.IP.ETH1). LOCAL.IP.ETH1 = Local net, static route to IP.TO.TRUNK. PUBLIC.IP.ETH0 = Public routable address. IP.TO.ASTERISK = Public routable address. The purpose of Kamailio/RTPProxy are to proxy everything between the routable and the private net. Does anyone here have any idea of how I'm going to solve my issue? It would also be nice if anyone here have better solutions to my approach, and there could also be some other errors in my config that causes this behaviour. ####### Routing ######## route { if (msg:len >= 2048) { sl_send_reply("513", "Message too big"); exit; } if (method != "INVITE" && method != "ACK" && method != "BYE" && method != "CANCEL") { sl_send_reply("503", "Service Unavailable"); exit; } if (!has_totag()) { record_route(); route("1"); } if (has_totag()) { if (!loose_route()) { if (t_check_trans()) { t_relay(); exit; } exit; } } if (has_body("application/sdp")) { if (method == "INVITE") { route("2"); t_on_reply("2"); } else if (method == "ACK") { rtpproxy_answer(); } } else if (method == "INVITE") { t_on_reply("2"); } if (method == "BYE" || method == "CANCEL") { unforce_rtp_proxy(); } t_relay(); } #RELAY BY SOURCE ROUTE route[1] { if (src_ip == "IP.TO.TRUNK" || dst_ip == "LOCAL.IP.ETH1") { force_send_socket("PUBLIC.IP.ETH0"); rewritehost("IP.TO.ASTERISK"); } else { force_send_socket("LOCAL.IP.ETH1"); rewritehost("IP.TO.TRUNK"); } } # RTP OFFER ROUTE route[2] { if (src_ip == "IP.TO.TRUNK" || dst_ip == "LOCAL.IP.ETH1") force_rtp_proxy("eir"); else force_rtp_proxy("ier"); } # RTP OFFER ONREPLY onreply_route[1] { if (has_body("application/sdp")) route("2"); } # RTP ANSWER ONREPLY onreply_route[2] { if (has_body("application/sdp")) route("2"); } ## END OF CONFIG Sorry for the long post, but I hope someone outthere are able to help med with this issue. -- Espen C.

Hello, several developers will be around Berlin in June 7-8 time frame and we think to organize a face to face meeting. It is a good time frame if you want to attend Amoocon in Rostock (June 4-6, aprox 230km north of Berlin) or LinuxTag (June 9-12, in Berlin). http://www.linuxtag.org/2010/ http://www.amoocon.de/2010 I will have two presentations at Amoocon, about Asynchronous processing in SIP Router / Kamailio and extending your routing logic with Lua (via the new app_lua module). Hennig has one talk at LinuxTag about Geographical redundant VoIP systems with Kamailio. So far, interest in event and participation was shown by: - Andrei Pelinescu-Onciul - Jiri Kuthan - Inaki Baz Castillo - Jesus Rodriguez - Elena-Ramona Modroiu - Daniel-Constantin Mierla - Henning Westerholt - Marcus Hunger A good number to move it into public space and see if others from community are interested in such event. Based on that we will decide the type of event and look for a proper place to host it. Among topics could be: hands on hacking or docs update sessions, quick start guide to start writing your own extensions as module, open debates about current devel state and future directions... Please drop an email if you want to participate to the event - there is no participation fee - however, late registrations may be rejected if the capacity of location is filled - priority is first come first served.

LCR in openser 1.2 - is it possible to disable a gateway?
by Iñaki Baz Castillo 24 Apr '10

24 Apr '10

Hi, I need to add LCR support to an existing OpenSer 1.2 server (not possible to upgrade it for now). I've realized that 1.2 doesn't include gateways monitorize feature. Ok, I can do the check with an external tool, but I would like some way to dissable such gw from the LCR module, something like upgrading the gw table and performing the MI reload function. But I don't see how to set in the gw table that such gateway is disabled. Is it possible? Thanks. -- Iñaki Baz Castillo <ibc(a)aliax.net>

Solutions to missing BYEs, accounting for them
by Alex Balashov 23 Apr '10

23 Apr '10

Hi all, Please forgive the slightly long post, but if you have anything to contribute on this topic, please consider giving it a read as I could really use your input. :-) As I'm sure many others of you running proxy-based service delivery platforms of some description also, I am faced with the problem of trying to account for calls with missing BYEs in a realistic way. There is no shortage of mailing list posts over the years on this topic. Inevitably, in a platform with sufficient call volume, with some NAT'd and/or endpoint diversity and other technical causes, there will be some calls that are never officially terminated from the point of view of a proxy. The ability of the 'dialog' module to spoof bidirectional BYEs on timeout[1] goes a long way toward addressing this problem theoretically. However, there are practical obstacles to relying on it solely as a solution, mainly because there is not an acceptable timeout value to use as a trade-off. If the timeout period is set to a very low value, users will obviously complain, and in any case, depending on the destination, the worst-case scenario for maximum call billing may still be far too high. If the timeout period is set high--perhaps something like 5-8 hours--then all calls that fail to end in the normal way will be billed some excessively large amount that certainly will not sit well with users either. If either the core delivery element of the platform or the user agent is tightly controlled by the operator of the proxy from an administrative point of view, it is indeed probably possible to rely on RTP timeouts or SIP Session Timers (SSTs) on one of the endpoints. That doesn't create a satisfying resolution for those of us dealing with indeterminate call completion scenarios with a great deal of user and vendor diversity, though. For instance, I route to about 15 ITSPs and carriers; I think maybe one of them does 15-minute SSTs, and the rest are certainly not going to turn them on just for me, even if their SBCs/switches/things have the capability. The user endpoints are mostly Asterisk and do RTP timeout, of course, and in most cases I do get the resulting BYE. However, this discussion is about the minute but nontrivial percentage of cases in which I do not get the BYE, whether because of NAT statekeeping problems or network reachability or whatever underlying causes--in truth, I cannot accurately characterise these. So, it seems to me that from a theoretical point of view, there are basically two directions someone in this position can go from here: 1) Inline B2BUA in the signaling path of all calls; 1a) Make it do SSTs; or 1b) Make it relay media, too, and hang up the call (bidirectional BYE) on RTP receive timeout; 2) Couple the proxy to an RTP relay and provide some mechanism by which the proxy can be made aware, in an asynchronous fashion, that an RTP timeout was detected by the relay. It seems to me from a brief and informal survey of prior mailing list literature that #1 is the usually recommended option here. If #1 is pursued, what is the best tool to use in the Kamailio/SIP-Router-oriented ecosystem? My default instinct would say SEMS; I really like SEMS, and use it a lot for various related chores. The problem is that the pre-built modules and examples for SEMS mostly center on application-level functionality, while low-level documentation of its powerful C++ API is a bit impoverished, so this would take a lot of work. Needless to say, I am interested in the option that requires the least work but still solves the problem in an elegant way from a technical and--dare I say--aesthetic perspective. For instance, it seems clear from looking at the SEMS-1.1.1 sources that SSTs are supported in principle in core/plug-in/session_timer. But unless I am missing something, I cannot find anywhere in the sources or examples where it is actually used. So, I suppose one option is to figure out how to make this stuff work in SEMS, and make it work. But for some reason who is not attune to the universe of its C++ API, it is a rather formidable chore. I think the same would hold true of making it observe bidirectional RTP timeout. Turning attention to option #2, I have looked at rtpproxy (my preferred default), iptrtpproxy, and mediaproxy modules but have not found any evidence that the control protocols Kamailio/SR uses to engage them support any notion of backward asynchronous feedback in case of RTP timeout. It would be really nice if one of these stream control protocols was augmented to kick back a packet to Kamailio that can be caught in a special event_route, like event_route[nathelper:rtp-stream-timeout], but that is clearly not the case today. To be honest, I would not use MediaProxy even if it had this feature, because, well, let's be bluntly honest and acknowledge what the more politically aware presumably already conjecture: in light of AG Projects' zealous OpenSIPS partnership, it's difficult to muster confidence in future compatibility of MediaProxy with Kamailio. The module is there, it works, and I'm sure its maintainers are dedicated to doing whatever it takes to reverse engineer and keep it working, lift patches from OpenSIPS as necessary, etc., but who wants to be on the wrong side of the project ecosystem fence? Not I. That leaves iptrtpproxy, whose 'switchboard' concept I do not fully comprehend due to lack of experience with it, but which holds a potentially viable, if slightly kludgy/Rube Goldbergian answer. Of the three RTP proxies, it is the only one that provides a ready means of exporting a list of media streams it is currently tracking, together with statistics on how many packets have been received, etc. It is not inconceivable to cook up an external process that will frequently check this 'switchboard', as it were, and incite Kamailio/SR to do dlg_bye() via MI if it appears that the media stream has disappeared from either side; the dialog module helpfully exports the MI command dlg_end_dlg. Still, this does not seem nearly as parsimonious and reliable a solution as simply building some kind of RTP stream leg timeout notification into the control socket. After all, the control socket is open persistently, right, not on-demand? The various RTP proxies all seem to have some kind of dead peer detection internally in order to have some means of gracefully expiring resources allocated to media streams that have gone away, so it would just be a matter of passing a control frame up the socket to Kamailio/SR and wiring that to a custom event_route or a more static callback in the code. By the way, I should mention that I am aware of and historically very sympathetic to the perspective that this kind of call control is alien to the nature of a proxy, and an appropriate job for UAs and not proxies at all. However, we all have to make pragmatic concessions to the realities of real-world operation, which I assume is the motivation for dialog timeouts, dlg_bye(), and other perversions from the point of view of a purist. :-) I welcome your thoughts and suggestions about the easiest and most technically meritorious approach.

new features: write access to branch attributes
by Daniel-Constantin Mierla 22 Apr '10

22 Apr '10

Hello, yesterday I committed to git new feature that allow write access to branch attributes. It is about branches kept in core before TM takes over and creates the branches for transaction. These branches are filled when you do location lookup, alias db lookup or append_branch in route block. You can update the attributes: - r-uri - outbound proxy address (dst uri) - path - q value - local socket to be used for sending - branch flags More at: http://sip-router.org/wiki/cookbooks/pseudo-variables/devel#branch_attribut… The access can be done with index, 0 is the first. Negative value of index starts counting from the last, therefore index -1 is the last branch. If the index is missing, then first branch is used. Adding a new branch can be done with km_append_branch(...) of kex module or append_branch() functions. Dropping a branch is by assigning $null to uri attribute of branch. Among benefits: - drop invalid branches before creating the transaction - you can lookup the aor from branches in location table, avoiding a loopback of a branch (e.g., for alias db case) Cheers, Daniel -- Daniel-Constantin Mierla * http://www.asipto.com/ * http://twitter.com/miconda * http://www.linkedin.com/in/danielconstantinmierla

Catching internally generated BYE event & other
by Alex Balashov 21 Apr '10

21 Apr '10

Hello, I am using the dialog module to time out excessively long calls: modparam("dialog", "default_timeout", 21600) # 6 hours modparam("dialog", "dlg_flag", 2) ... route { ... ... setflag(2); $dlg_ctx(timeout_bye) = 2; ... ... if(!t_relay()) sl_reply_error(); } I have two unrelated questions: 1) Why does $dlg_ctx(timeout_bye) work here? My understanding is that $dlg_ctx(...) is a PV namespace container that exposes some aspect of the allocated dialog tracking structure. The dialog structure is created via a TM->dialog callback triggered by t_relay(); why is it possible to access it prior to that point? 2) The spoofed BYEs that are generated by the proxy with this setting do not show up as sequential requests, nor are catchable in script at all. As a result, BYE events are not written to CDRs with 'acc' and I have no way of knowing when the call actually closed. What is the most efficient and canonical solution to this problem? I can think of two: (a) Define a $dlg_ctx(timeout_route) and have it write a BYE event artificially using acc_db_request(). (b) Loop the BYE request back to the proxy with some sort of differentiating URI parameter or similar that causes it to be dropped instead of forwarded. But this is really nasty. What is your suggestion?

SQLOps question

Hello, I am trying to use SQLOps Module in my kamailio 1.5 configuration. According to your explanations every result of sql_query should be freed just after using that data. So it means that there will be better to fetch for THE SAME data three times instead of just one. Am I right? But nevertheless I've been trying to query just one and free the result of the sql_query at the end of the file. Could sb tell me if the result of sql query executed in the main part of the script is remembered and could be used on failure route as well? Thanks, Maciej.

PVs in Regular Expression Transformations

i tried to embed a PV in regex transformation, but didn't get desired result. is it possible or must regex only contain strings. here is an example, where the idea is to strip string "456" from the end of string "123456": $var(test) = "123456"; $var(rest) = "456"; $var(test) = $(var(test){re.subst,/^(.*)$var(rest)$/\1/}); xlog("result is $var(test)\n"); unfortunately, the result is 0 rather than "123". i also tried $var(test) = $(var(test){re.subst,/^(.*)\$var(rest)$/\1/}); and $var(test) = $(var(test){re.subst,/^(.*)$(var(rest))$/\1/}); but still 0. -- juha

[Kamailio-Users] new module: embedded lua
by Daniel-Constantin Mierla 20 Apr '10

20 Apr '10

Hello, few weeks ago I uploaded a new module named app_lua, providing functionality to execute Lua (http://www.lua.org) scripts in your configuration file. Lua is small and fast, therefore fits very well in a sip proxy environment. It has a lot of extensions, so when you cannot do something with existing cfg functions, check this one as well. The readme and the api are available at: http://sip-router.org/wiki/api/lua/devel http://sip-router.org/docbook/sip-router/branch/master/modules/app_lua/app_… The API will be enhanced during this development cycle, your feedback will help a lot in this direction. By now you get access to pseudo-variables, sip headers, logging functions and sl module. For new comers in community, if you are a Perl fan, then you can use the perl module in a similar way. Also, another module was uploaded recently, app_python, allowing to write python extensions. Module and API for Python are not yet documented, but I think this is not a barrier for a true Python fan, actually I hope will be a motivation to contribute the docs :-) Cheers, Daniel -- Daniel-Constantin Mierla SIP Server Professional Solutions * http://www.asipto.com/

Hello, Scenario 1 ---------- --------- -------- -------- -------- -------- |Cellphone|--|Wireless|--|Internet|--|Kamailio|--|Asterisk| | | |Router | | | |rtpproxy| | | --------- -------- -------- -------- -------- |<-Lowlatency->| Scenario 2 ---------- --------- -------- -------- -------- -------- |Cellphone|--|Wireless|---|Internet|--|Kamailio|--|Asterisk| | | |Router | | | |rtpproxy| | | --------- -------- -------- -------- -------- |<-Highlatency->| Both scenario 1 and scenario 2 are similar in setup, excepting that in scenario 2 there is a greater latency involved in SIP and RTP transmission between the wireless router and Kamailio+rtpproxy server. In scenario 1 calls from the cellphone using a SIP softphone app go through 100% of the time with both endpoints of the call being audible. However in scenario 2, calls from the cellphone go through with both endpoints of the call being audible only sometimes, and during all other attempts, call goes through with no voice from the cellphone. In scenario 2 the SIP softphone can always register, the SDP connection address is always rewritten to use rtpproxy so it does not appear to be a NAT issue, rtpproxy's logs show a session being set up and torn down, with RTP stats for caller being 0. In both scenarios, the equipment and their configuration are identical. (Both cellphone's are Nokia e51, router's are Netgear wgr614) What might be probable causes for the behavior seen in scenario 2 ? Could there be a timing/latency related issue ? Any pointers on how to approach this problem will be appreciated. Thanks and Regards, Vikram.

loadbalancer
by Hector Muñoz 19 Apr '10

19 Apr '10

Hi all, I have a kamailio sip server with two trunk connections to two asterisk servers. The register server is kamailio. I'd like to be able to configure a load balancing with kamailio between two asterisk servers. How can i do that? Do you know any good tutorial for configure load balancing with dispatcher module in kamalio? Thanks in advance. Regards. -- jabber: triptik(a)12jabber.com blog: http://impresionesdeunloco.wordpress.com

load balancing redirect
by Benjamin Lawetz 17 Apr '10

17 Apr '10

Hi, I'm trying to setup Kamailio to act as a load-balancer in front of asterisk servers. I want it to do the following: - The UA sends an invite to Kamailio - Kamailio sends a 30x redirect to the UA (dispatcher) - The UA sends it's invite to the asterisk server I've seen a couple of examples, but doesn't seem to work for me. Here's the relevant config: route{ if (method=="REGISTER") { [...clip...] }; if (method=="INVITE") { ds_select_domain("2","8"); #ds_select_dst("2","8"); sl_send_reply("300","Redirect"); exit; }; } What seems to happen is that Kamailio does send the redirect, but with no indication of where to go. ds_select_domain (or ds_select_dst ... I having trouble understanding the difference like many people it seems) I'm guessing selects an appropriate uri, but doesn't put it the contact for the redirect. Is there anyway to see what was set by the ds_select_dst? what pv would have this value? What do I need to set prior to sending a redirect reply for it to be properly forwarded? BTW: using Kamailio 3.0.1 Thank you, -- Benjamin

reply when drop() in branch route
by jh＠tutpro.com 17 Apr '10

i call drop() in branch route and it is the only branch left. the branch gets correctly dropped, i.e., the request is not send out, but the reply to UAC is strange: U 2010/04/14 21:03:43.750712 192.98.102.10:5060 -> 192.98.103.2:5074 SIP/2.0 477 Unfortunately error on sending to next hop occurred (477/TM).

Please, keep the mail within the maillist thread. No, it doesn't add too much load to Kamailio. This is one of the major purposes of a transaction stateful proxy (the serial forking in order to implement failover). Take a look to the LCR module. It gives you load balancing (with priorities if you want) and failover features. It's all you need in your scenario. -- Iñaki Baz Castillo <ibc(a)aliax.net>

call not being accounted when rejected by global blacklist
by Panagiotis Skoulikaritis 15 Apr '10

Dear list members I'm using kamailio 3 and the problem that I'm facing is that when a call is rejected by global blacklist, kamailio does not generate an accounting record. Is this normal behavior or I need to configure something somewhere ?

[Kamailio-Users] PKG memory issues
by Iñaki Baz Castillo 15 Apr '10

15 Apr '10

Hi, I've experimented PKG out of memory in a production server. Of course I'm already increasing such value but I would like to know if the current settings and traffic could run into PKG memory issues: - Dual core INTEL XEON 3.00 GHz server. - Kamailio PKG memory = 4 MB. - Kamailio Shared memory = 64 MB. - Kamailio just listens in a single UDP port (8 childrens). - Just INVITE method is handled (no registration, no subscription). The script does the following for each request: - 'permissions' module to match source IP (just ~20 entries in 'address' table). - 2 custom SQL queries (returning a simple value). - 'dialog' memory (just in memory). - 'uac' module to change From header. - There are 10 AVP's set per transaction. - 'lcr' module for routing to two gateways (just 2 entries in 'lcr' table). - 'rtpproxy' is forced for every call. The server has been working properly for months but these days the traffic has been duplicated, having ~400 simultaneous calls in peak hours. Also note that such calls come from callcenters so they are ver "fast". With this environment, is it normal to get into PKG memory issues (4 MB)? I understand that it makes sense, but I would like to hear some opinions. Thanks a lot. -- Iñaki Baz Castillo <ibc(a)aliax.net>

[NAT] BYE not received to caller
by Pascal Maugeri 14 Apr '10

14 Apr '10

Hi I need some "guidelines" to troubleshoot the following issue: a) A is behind NAT b) B is not behind NAT c) A calls B, SIP INVITE is sent over TCP d) A's firewall does NAT and changes the source port to let's say p1 e) B releases the call and sends BYE over UDP f) Kamailio sends the BYE to A, over UDP, to the NATed source port p1 ?! 2 comments: - This scenario works perfectly when A is the one who disconnects the call. and of course when no NAT is involved everything works ok - if works when I comment the line "fix_nated_contact()" in the route[NAT] block: route[NAT]{ #!ifdef WITH_NAT force_rport(); #if (nat_uac_test("19")) { if (nat_uac_test("3")) { if (method=="REGISTER") { setbflag(10); fix_nated_register(); } else { #fix_nated_contact(); [...] Any hint is very welcome.

Failure to load module db_mysql.so due to undefined symbol: log
by Pratab Ali 14 Apr '10

14 Apr '10

Hello, I have installed from source version 3.0.1 of Kamailio on an OpenSuSE 10 Linux system. Currently I am attempting to enable persistence in my Kamailio with the help of MySQL. In the config file kamailio.cfg I have enabled MySQL as follows #!define WITH_MYSQL In the config file db_mysql.so is the first module to be loaded by calling loadmodule, but the module fails to load. By turning, Kamailio, debugging on I get the following explanation. 0(9858) DEBUG: <core> [sr_module.c:382]: load_module: trying to load </usr/local/lib/kamailio/modules/db_mysql.so> 0(9858) ERROR: <core> [sr_module.c:390]: ERROR: load_module: could not open module </usr/local/lib/kamailio/modules/db_mysql.so>: /usr/local/lib/kamailio/modules/db_mysql.so: undefined symbol: log Using the unix/linux tool 'nm' I see the following. mindy:~/tmp # nm /usr/local/lib/kamailio/modules/db_mysql.so | grep log U getlogin@@GLIBC_2.0 U log 001a6e40 R log_10 001e5d00 D log_10_int U log_level_info U log_stderr U syslog@@GLIBC_2.0 And for sure the capital 'U' means undefined. I have also searched the source code that came with the kamailio package, for definitions of 'log'. And it also looks like I'll be in trouble later for log_level_info, log_level_stderr and syslog are undefined too. However, log_level_info I have just found in source files in the kamailio package. So, why isn't it linking in? Unfortunately, searching on the internet I have not yet come across a forum post that tackles the above issue. As, I suspect everyone else has got the build right. Have I built db_mysql.so incorrectly? Though I built it using the make files that came with the package. Is it a case of linking in the appropriate libraries to resolve these undefined symbols? Finally, I have a colleague who has used the same version of kamailio but installed on a Debian lenny distro. He has been successful in getting db_mysql loaded and persistence enabled. However, he has an older version of mysql (by only one minor-version number) though. Having looked that the changes' history for the two mysql versions, I see no obvious reasons that could be the cause of my failure. By comparing notes, he did nothing too different than I did. We both followed the instructions in the INSTALL and README files. There is no particular reason for me using OpenSuSE 10 other than it was already installed and the computer was not being used by anyone. I am considering installing Debian Lenny on my computer to match my colleague, would this be prudent or a waste of time? i.e I may face my same problem because I'm missing a stage? Regards and thank you, in advance, for any help given. Pratab

[Kamailio-Users] Relaying NOTIFY UDP messages over TCP
by Pascal Maugeri 14 Apr '10

14 Apr '10

Hi We need to force some NOTIFY messages going through our kamailio instance over UDP to be sent over TCP. For that purpose we inserted the following relaying rule at the beginning of the routing script: route{ if (!mf_process_maxfwd_header("10")) { sl_send_reply("483","Too Many Hops"); exit; } if(msg:len>1300 && is_method("NOTIFY") && proto==UDP) { $du = "sip:" + $(ruri{uri.host}) + ":" + $(ruri{uri.port}) + ";transport=tcp"; t_relay(); exit; } [...] This works well if the destination of the NOTIFY message is not behind NAT. We're looking for a solution for the NAT case. We did some tests using lookup("location") before changing $du but we did not get any success. Do you have any idea on how to implement this relaying properly ? Is it acceptable to change the $du and then execute the t_relay as we did ? Cheers Pascal

when mySQL is unreachable ...
by Alex rsm 14 Apr '10

14 Apr '10

Hi, My Kamailio server uses an external mysql database with perl script to proxy traffic. When mysql server is unreachable, Kamailio do not respond with 100 Trying and instead responses with 484 (Address Incomplete) to the INVITE message. Is this a normal behavior? I need to response with 503 when mysql is unreachable. Can I do it in kamailio.cfg or I need to implement it in the perl script?

when mySQL is unreachable ...
by Robert R 13 Apr '10

13 Apr '10

Hi, My Kamailio server uses an external mysql database with perl script to proxy traffic. When mysql server is unreachable, Kamailio do not respond with 100 Trying and instead responses with 484 (Address Incomplete) to the INVITE message. Is this a normal behavior? I need to response with 503 when mysql is unreachable. Can I do it in kamailio.cfg or I need to implement it in the perl script? Thanks, R

Compiling and installing sip-router with some SER modules
by Steven C. Blair 13 Apr '10

13 Apr '10

I'd like to build the latest version of sip-router from source but include server modules from the modules_s directory. I thought the command 'make include_modules="modules_s/permissions modules_s/pike modules_s/ratelimit modules_s/sms modules_s/sanity" ' would do the trick but it doesn't. Instead all modules from the modules_s are built. Is there a way to compile and install the core + modules_s/(permissions,pike,ratelimit,sms,sanity) ? Thanks --- ISC Networking & Telecommunications 3401 Walnut Street, Suite 221A Philadelphia, PA 19104 215-573-8396 215-898-9348 (fax)

[OT] Nagios SIP Plugin
by Iñaki Baz Castillo 13 Apr '10

Hi, I've coded a SIP plugin for Nagios. There is some other similar plugin but it's less customizable and less powerful. Homepage: http://dev.sipdoc.net/projects/sip-stuff/wiki/NagiosSIPplugin Features: - SIP UDP and TCP transport protocols. - Customizable parameters (From URI, Request URI, server address, local UDP port, timeout internal). - The replied status code can be matched against an expected value to be considered as valid.

Calling number Routing possibility in 1.5rel.
by Maciej Bylica 13 Apr '10

13 Apr '10

Dear ALL, I am playing around with kamailio 1.5. Could somebody explain me what module best fit to route the call on the basis of number A (calling number). What is more all rules should be able to be modified directly from mysql db. I've run through 3.0 modules and figured out that there is drouting module which is really great, but is it present in 1.5 rel? If negative, what other modules can be used. Thx in advance, Maciej.

Allow cfg_get parameters to be used as modparams, too, so I can define one set of global database properties and pass them as db_urls to every module that uses one and also to 'sqlops' as an 'sqlcon', and similar things. -- Alex Balashov - Principal Evariste Systems LLC 1170 Peachtree Street 12th Floor, Suite 1200 Atlanta, GA 30309 Tel: +1-678-954-0670 Fax: +1-404-961-1892 Web: http://www.evaristesys.com/

Close TLS connection and Registrar Server (Kamailio V1.4.x)
by edson.gomes.leme 11 Apr '10

11 Apr '10

Hello, We are using Kamailio V1.4 with TCP/TLS. The Kamailio is configured the TCP lifetime to the expire value of the REGISTER by using the tcp_persistent_flag parameter of Kamailio's registrar module. Note: The SIP proxy should not close the TCP connection as it is not capable of opening a new one. Kamailio tries to open a TLS connection to the client. The Kamailio should use the existing TLS/TCP connection that was established by the client during registration. We are applying NAT traversal techniques to instruct Kamailio to reuse the established TCP/TLS connection. Example: for each register call fix_nated_register(). For every other request and response call fix_nated_contact(). I have got one SIP phone registered via TLS to kamailio-1.4.X version with Expires = 3600. phone1: connected via ip1:port1 and Expires = 3600. Example: After 15 minutes TLS connection is closed. The SIP Phone opens a new TLS connection and registers via TLS to Kamailio. Thus, we have the following records on the Registrar Server (Kamailio): phone1: connected via ip1:port1 and Expires = 2700 [3600 – (15 min * 60 s) = 2700]. phone1: connected via ip1:port2 and Expires = 3600. Is this the desirable behavior? Shouldn’t the Kamailio (Registrar Server) delete the below registry? phone1: connected via ip1:port1 and Expires = 2700 [3600 – (15 min * 60 s) = 2700]. Best regards!

users@kamailio and sr-users@sip-router merged
by Daniel-Constantin Mierla 10 Apr '10

10 Apr '10

Hello, the process of merging users(a)list.kamailio.org and sr-users(a)lists.sip-router.org is completed, offering a single place for community discussions via email related to stable versions and generic topics, also removing confusion for new comers which to use for best feedback. Because sr-users was a rather new mailing list, I imported the archive from users. It will help to continue the topics and have the entire knowledge base built over years in the same place, for web searches. The old Users mailing list archive still exists separately, link at: http://lists.kamailio.org/pipermail/users/ No new posts will get there, subscription is disabled, messages to users list are directed to sr-users (therefore replying to existing threads on either of the mailing lists work just fine). No matter you were a Users or SR-Users subscriber, updates to your profile can be done at: http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users I case your password is no longer valid, you can retrieve it via password reminder at: http://lists.sip-router.org/cgi-bin/mailman/options/sr-users Thanks, Daniel PS. Some of you may have received an unintentional "unsubscribed from sr-users-new mailing list" message, just ignore it - happened when I simulated synchronization of members on temporary name sr-users-new, no unsubscribe action was actually done -- sorry for inconvenience. -- Daniel-Constantin Mierla

[Kamailio-Users] dispatcher has problems
by Vic Jolin 09 Apr '10

I just noticed that if I have 4 servers set like this # group sip addresses of your * units 1 sip:XXX.XXX.XXX.XXX:5060 1 sip:XXX.XXX.XXX.XXX:5060 1 sip:XXX.XXX.XXX.XXX:5060 1 sip:XXX.XXX.XXX.XXX:5060 the registration does not work and I get 401 unauthorized. My setup is like this Openser as proxy sends all SIP messages to load balanced asterisk servers So sip phones should be able to register to the asterisk server The routing part in kamailio.cfg looks like this if ( method=="REGISTER" || method=="NOTIFY" || method=="OPTIONS" || method=="ACK" || method=="MESSAGE") { fix_nated_contact(); fix_nated_register(); ds_select_dst("1","4"); forward();#uri:host, uri:port); exit(); } if (method=="BYE" || method=="CANCEL") { unforce_rtp_proxy(); } else if (method=="INVITE"){ log("VCTOR: Got an invite\n"); fix_nated_contact(); force_rtp_proxy(); ds_select_dst("1","4"); forward();#uri:host, uri:port); t_on_failure("1"); }; search_append('Contact:.*sip:[^>[:cntrl:]]*', ';nat=yes'); t_on_reply("1"); if (!is_method("INVITE|REGISTER|MESSAGE|BYE|NOTIFY|ACK|CANCEL|REFER|SUBSCRIBE|OPTIONS|INFO")) { xlog("L_INFO", "=== [$rm] Method Not Implement ===========\n"); sl_send_reply("501", "Not implemented here"); return; }; any thoughts?

[Kamailio-Users] lcr module creating extra branch
by Jon Bonilla 09 Apr '10

09 Apr '10

Hi I am using Kamailio 3.0.1 and experiencing a strange behaviour of the lcr module. In short: Using next_gw() function makes my server to send two INVITEs to different destinations! The INVITE Kamailio receives is like: R=sip:4644235465675757@77.77.77.77 F=sip:manwe2@77.77.77.77 T=sip:4644235465675757@77.77.77.77 To try this I have set this in my gw table: sercmd lcr.dump_gws { lcr_id: 1 grp_id: 17 ip_addr: 91.121.117.27 hostname: sindominio.net port: 5080 scheme: sip transport: UDP strip: 0 tag: weight: 1 flags: 37 defunct_until: 268313248 } sercmd lcr.dump_lcrs { lcr_id: 1 prefix: from_uri: grp_id: 17 priority: 1 } Hostname and ip_addr don't match (sindominio.net points to 82.144.4.26). What I capture leaving Kamailio is: U 2010/04/08 17:51:09.614055 77.77.77.77:5060 -> 91.121.117.27:5080 INVITE sip:+4644235465675757@77.77.77.77 SIP/2.0' Record-Route: <sip:77.77.77.77;lr=on;ftag=hgtcn;nat=yes;vsf=czFwOgs5JCAEJEYoJGk3ajxNYmBrPBYC>' Via: SIP/2.0/UDP 77.77.77.77;branch=z9hG4bK90e8.cd3135e1.0' Via: SIP/2.0/UDP 10.0.0.92;received=91.115.172.34;rport=53658;branch=z9hG4bKiwibmejv' Max-Forwards: 69' To: <sip:4644235465675757@77.77.77.77>' From: "1102" <sip:1102@77.77.77.77>;tag=hgtcn' Call-ID: qxvyddwlnmurqvi@multivac' CSeq: 571 INVITE' Contact: <sip:manwe2@91.115.172.34:53658>' Content-Type: application/sdp' Allow: INVITE,ACK,BYE,CANCEL,OPTIONS,PRACK,REFER,NOTIFY,SUBSCRIBE,INFO,MESSAGE' Supported: replaces,norefersub,100rel' User-Agent: Twinkle/1.4.2' Content-Length: 226' ' v=0' o=twinkle 1296734594 70729915 IN IP4 77.77.77.77' s=-' c=IN IP4 77.77.77.77' t=0 0' m=audio 38232 RTP/AVP 8 101' a=rtpmap:8 PCMA/8000' a=rtpmap:101 telephone-event/8000' a=fmtp:101 0-15' a=ptime:20' a=nortpproxy:yes' # U 2010/04/08 17:51:09.614074 77.77.77.77:5060 -> 82.144.4.26:5060 INVITE sip:+4644235465675757@sindominio.net SIP/2.0' Record-Route: <sip:77.77.77.77;lr=on;ftag=hgtcn;nat=yes;vsf=czFwOgs5JCAEJEYoJGk3ajxNYmBrPBYC>' Via: SIP/2.0/UDP 77.77.77.77;branch=z9hG4bK90e8.cd3135e1.1' Via: SIP/2.0/UDP 10.0.0.92;received=91.115.172.34;rport=53658;branch=z9hG4bKiwibmejv' Max-Forwards: 69' To: <sip:4644235465675757@77.77.77.77>' From: "1102" <sip:1102@77.77.77.77>;tag=hgtcn' Call-ID: qxvyddwlnmurqvi@multivac' CSeq: 571 INVITE' Contact: <sip:manwe2@91.115.172.34:53658>' Content-Type: application/sdp' Allow: INVITE,ACK,BYE,CANCEL,OPTIONS,PRACK,REFER,NOTIFY,SUBSCRIBE,INFO,MESSAGE' Supported: replaces,norefersub,100rel' User-Agent: Twinkle/1.4.2' Content-Length: 226' ' v=0' o=twinkle 1296734594 70729915 IN IP4 77.77.77.77' s=-' c=IN IP4 77.77.77.77' t=0 0' m=audio 38232 RTP/AVP 8 101' a=rtpmap:8 PCMA/8000' a=rtpmap:101 telephone-event/8000' a=fmtp:101 0-15' a=ptime:20' a=nortpproxy:yes' My kamailio.cfg script does something like this: if(!load_gws("1", "$ru")) ... if(!next_gw()) ... t_on_branch("BRANCH_ROUTE_CLI_RTP"); if(!t_relay_to("0x01")) ...

[Kamailio-Users] sr-docs mailing list

Hello, I renamed kamailio-docs(a)lists.kamailio.org to sr-docs(a)lists.sip-router.org. Info about it at: http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-docs Lately, several discussions touched the documentation aspects, in a need for a better structuring and updates for the new context of sip router project. The old mailing list was active for a while, but with the start of sip router project was ignored because of more focus on integration work. I hope some of you will join, help to build new documentation and spot mistakes in existing versions. Volunteers that want to lead various documentation efforts are more than welcome! Just say what you need... Thanks, Daniel -- Daniel-Constantin Mierla * http://www.asipto.com/ * http://twitter.com/miconda * http://www.linkedin.com/in/danielconstantinmierla

[Kamailio-Users] Kamailio Blocking

Hello List, I have been running a very stable Kamailio 1.4 install for over a year now with no downtime. From time to time I get a message from the OS telling me that task kamailio:xxxx blocked for more than 120 seconds and a dump into syslog. I recently setup Kamailio 3.01 and it's been running for around 3 weeks now. Purely testing at the moment, there is only 1 SIP registration and almost no activity most of the time. I was checking dmesg and: [269844.208011] INFO: task kamailio:28504 blocked for more than 120 seconds. [269844.208093] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.

[Kamailio-Users] fr_inv_timer in kam-3.0
by Andreas Granig 09 Apr '10

09 Apr '10

Hi, In the docs at http://kamailio.org/docs/modules/3.0.x/modules/tm.html#fr_inv_timer it says that fr_inv_timer_avp should be defined like this, without $ or $avp: modparam("tm", "fr_inv_timer_avp", "my_fr_inv_timer") In kam <= 1.5 I did it like that: modparam("tm", "fr_inv_timer_avp", "$avp(s:callee_fr_inv_timer)") which doesn't give me an error on startup with kam-3.0 either, but the timer doesn't get fired (I use seconds for that as noted in the docs). If I change it to modparam("tm", "fr_inv_timer_avp", "callee_fr_inv_timer") then I get the error "malformed or non AVP callee_fr_inv_timer AVP definition", same with setting it to "s:callee_fr_inv_timer". Anyhow, it seems to be deprecated anyways, so I'm looking to get t_set_fr() working. I'm just curious how I can use a var or AVP loaded from DB to set the value on-the-fly? t_set_fr(...) seems to allow only constants to be set. Couldn't find anything in the docs regarding that one. Thanks, Andreas

[Kamailio-Users] drop in branch/onsend-route in kam-3.0
by Andreas Granig 08 Apr '10

08 Apr '10

Hi, Looks like behavior of drop has changed in Kamailio 3.0. Before, I was able to drop() a specific branch in branch_route depending on various checks. http://www.kamailio.org/dokuwiki/doku.php/core-cookbook:3.0.x#drop still says this is possible, http://kamailio.org/docs/modules/3.0.x/modules/tm.html#t_on_branch says it's not possible. So calling drop() in branch_route has no effect, and I have no idea how to mark a branch in branch_route to be dropped in onsend_route, because checking a bflag doesn't work there, and neither does checking $rU. Any ideas on how to accomplish dropping a specific branch? Andreas

[Kamailio-Users] Understanding memory-leaks by inspecting PKG/SHM memory status at shutdown
by Iñaki Baz Castillo 08 Apr '10

08 Apr '10

Hi, according to the wiki page: http://www.kamailio.org/dokuwiki/doku.php/troubleshooting:memory In order to detect a possible memory leak (in PGK or SHM) a good way is enabling memory debugging and shuting down the server, so: "the memory manager will dump the memory status. Normally most of the memory is cleaned during shutdown. If there is memory leak, it should be visible as not-freed memory." But I would like to know how exactly to detect if there is a memoty leak by inspecting the SHM/PKG status, something like this: ----------------------------------------------------------------------------------------------------------------------------- [32715]: Memory status (pkg): [32715]: fm_status (0x701a40): [32715]: heap size= 16777216 [32715]: used= 189696, used+overhead=247392, free=16529824 [32715]: max used (+overhead)= 247392 [32715]: dumping free list: [32715]: hash = 1 fragments no.: 1, unused: 0#012#011#011 bucket size: 8 - 8 (first 8) [32715]: hash = 2058 fragments no.: 1, unused: 0#012#011#011 bucket size: 8388608 - 16777216 (first 16530136) [32715]: TOTAL: 2 free fragments = 16530144 free bytes [32678]: Memory status (shm): [32678]: fm_status (0x7fa57921c000): [32678]: heap size= 67108864 [32678]: used= 16, used+overhead=35872, free=67072992 [32678]: max used (+overhead)= 2821064 [32678]: dumping free list: [32678]: hash = 1 fragments no.: 45, unused: 0#012#011#011 bucket size: 8 - 8 (first 8) [32678]: hash = 2 fragments no.: 4, unused: 0#012#011#011 bucket size: 16 - 16 (first 16) [32678]: hash = 3 fragments no.: 16, unused: 0#012#011#011 bucket size: 24 - 24 (first 24) [32678]: hash = 4 fragments no.: 2, unused: 0#012#011#011 bucket size: 32 - 32 (first 32) [32678]: hash = 5 fragments no.: 1, unused: 0#012#011#011 bucket size: 40 - 40 (first 40) [32678]: hash = 6 fragments no.: 1, unused: 0#012#011#011 bucket size: 48 - 48 (first 48) [32678]: hash = 7 fragments no.: 39, unused: 0#012#011#011 bucket size: 56 - 56 (first 56) [32678]: hash = 8 fragments no.: 1, unused: 0#012#011#011 bucket size: 64 - 64 (first 64) [32678]: hash = 9 fragments no.: 1, unused: 0#012#011#011 bucket size: 72 - 72 (first 72) [32678]: hash = 10 fragments no.: 2, unused: 0#012#011#011 bucket size: 80 - 80 (first 80) [32678]: hash = 15 fragments no.: 1, unused: 0#012#011#011 bucket size: 120 - 120 (first 120) [32678]: hash = 25 fragments no.: 1, unused: 0#012#011#011 bucket size: 200 - 200 (first 200) [32678]: hash = 40 fragments no.: 5, unused: 0#012#011#011 bucket size: 320 - 320 (first 320) [32678]: hash = 112 fragments no.: 1, unused: 0#012#011#011 bucket size: 896 - 896 (first 896) [32678]: hash = 128 fragments no.: 4, unused: 0#012#011#011 bucket size: 1024 - 1024 (first 1024) [32678]: hash = 129 fragments no.: 2, unused: 0#012#011#011 bucket size: 1032 - 1032 (first 1032) [32678]: hash = 224 fragments no.: 1, unused: 0#012#011#011 bucket size: 1792 - 1792 (first 1792) [32678]: hash = 258 fragments no.: 3, unused: 0#012#011#011 bucket size: 2064 - 2064 (first 2064) [32678]: hash = 473 fragments no.: 1, unused: 0#012#011#011 bucket size: 3784 - 3784 (first 3784) [32678]: hash = 1026 fragments no.: 1, unused: 0#012#011#011 bucket size: 8208 - 8208 (first 8208) [32678]: hash = 2049 fragments no.: 2, unused: 0#012#011#011 bucket size: 16384 - 32768 (first 16512) [32678]: hash = 2051 fragments no.: 1, unused: 0#012#011#011 bucket size: 65536 - 131072 (first 98336) [32678]: hash = 2056 fragments no.: 1, unused: 0#012#011#011 bucket size: 2097152 - 4194304 (first 2621440) [32678]: hash = 2060 fragments no.: 1, unused: 0#012#011#011 bucket size: 33554432 - 67108864 (first 64287800) [32678]: TOTAL: 137 free fragments = 67072992 free bytes ----------------------------------------------------------------------------------------------------------------------------- This is, how should look this SHM/PKG status example (after shutdown) in case there is a memory leak? how to detect not-freed memory?

[Serusers] ReTransmission of CANCELs on 0.9.7
by rupert.organ＠bt.com 08 Apr '10

08 Apr '10

Hi All, Has anyone come up against an issue on 0.9.6 / 0.9.7 whereby a SIP App Server, delivers a CANCEL to the SER. The SER proxies the CANCELs to all the forked endpoints. At the same time it sends "200 Cancelling" back to the SIP App server...(this suppresses CANCEL retransmission from the SIP App server). If one of the CANCELs from the SER to the SIP UA gets lost....the phone keeps ringing. There is no CANCEL retransmission on the SER !!! There is CANCEL retransmission on the SIP App, but when it sends SER replies "no pending branches" Ideally want the SER do CANCEL retransmissions. I understand the timers were rewritten in 0.10.x but this is not hardened version like 0.9.6....any suggestions? Thanks in advance Rupert

[Kamailio-Users] merging users mailing lists
by Daniel-Constantin Mierla 08 Apr '10

08 Apr '10

Hello, I propose to merge the users mailing lists, most of the traffic these days is about 3.0 and even there are 2 stables branches now, they are sync'ed, so same code more or less. For 3.1 will be one stable branch, falvor selection will be only a matter of make command. Lately common useful topics are discussed on those different mailing lists, notifications and knowledge base building require cross-posting, lot of overhead imo. Any other opinion? Like with devel mailing lists, existing email addresses for users ML can still be used, just that end on same ML. Natural choice will be to have users@kamailio and serusers@iptel to be directed to sr-users(a)lists.sip-router.org Cheers, Daniel -- Daniel-Constantin Mierla * http://www.asipto.com/

Hi all! For easy editing kamailio configuration files I developed a syntax highlighting scheme for mc. Preview The scheme includes basic syntactic structures of Kamailio 1.5, all constants, variables, operators and standart core functions. To install it, download the file kamailio.syntax from attachment and copy it to /usr/share/mc/syntax (for Debian Etch) Next, add to the file /usr/share/mc/syntax/Syntax including: file ..\*\\.cfg$ Kamailio\sconfig include kamailio.syntax Thats all, I hope its helps someone ;) -- Shpinev Konstantin mailto:kks_mail@inbox.ru
