Re: [SR-Users] mtree question
by Javier Gallart 18 Aug '11

18 Aug '11

Hi Juha based on my experience with the mtree module: -mt_match() will match the longest prefix in the tree, in your case 00358 -mt_ignore_duplicates makes sense when loading the data in the DB to the memory. There could be duplicate entries in the db and with that directive you tell kamailio how to handle that situation -I don't know about mt_tree_type...(never needed to test it) Hope it helps Regards Javi > ------------------------------ > > Message: 2 > Date: Fri, 12 Aug 2011 10:10:29 +0300 > From: Juha Heinanen <jh(a)tutpro.com> > Subject: [SR-Users] mtree question > To: sr-users(a)lists.sip-router.org > Message-ID: <20036.53733.20652.518606(a)sip.test.fi> > Content-Type: text/plain; charset=us-ascii > > after reading mtree readme, it is not clear to me if mt_match() matches > to longest or any matching prefix in the three. for example, if i have > tree with prefixes 00 and 00358 and string to be matched is > 0035892345670, will mt_match() set pv to value associated with 00 or > 00358? also, if mt_ignore_duplicates is set, will 00358 be considered > as duplicate of 00 or just prefixes that are exactly same. finally, > what are possible mt_tree_type values and what types they stand for? > > -- juha > > > > ------------------------------ > > _______________________________________________ >

lookup for specified user
by Efelin Novak 17 Aug '11

17 Aug '11

Hi folks, I discussed this issue in previous email ( [SR-Users Modifying $rU after lookup() ) but the question is a bit different now. I would like to change uri like lookup() function does it, but for the specific user. Problem is I want to have one registration (X) for several numbers. When this number is called I have to perform lookup() for this one common registration (X) and send this call there. To do this I changed $rU just before lookup() for X, and after lookup() I changed it back for the original number (both changes were done using variables $rU). However when there are two registrations (X1, X2), only X1 can be changed for the original number and the second one (X2) is sent to user without modification. I also found function reg_fetch_contacts(domain, uri, profile) but in documentation there is $ulc variable mentioned. This variable is not documented. Is there any way how to perform lookup for specific user? Thanks for the answer. Regards, Efelin

siptrace loosing an ACK
by Timo Klecker 17 Aug '11

17 Aug '11

Hello We are using the siptrace module to save the sip-messages to our database. All the messages are logged except one message. After INVITE, 100 trying and 200 OK we loose the outbound ACK which is forwarded by Kamailio statelessly in t_funcs.c. Is there any way to get a siptrace of this message, too? I've made a picture of the sip-messages and the lost ACK. Kind regards Timo Klecker

Any ideas? thanks, Jon

openSIPS vs Kamailio vs SIP-Router
by Nick Khamis 15 Aug '11

15 Aug '11

Hello Everyone, I can only imagine how many times this question has come up since post 2008. Please forgive my reoccurring of the issue. We are looking to provide carrier grade sip services to our clients world wide. What we need is a lightweight, robust and scalable solution that will allow us to terminate sip calls to our different carriers. Performance, and high throughput are factors very important to my employer. Features such as caller authentication, database back-end, load balancing, and interoperability with asterisk are things we are interested in, as was offered using OpenSER. With three+ open source proxy servers available on the net puts us in a situation where we have more solutions to choose from, at the same time wish the features from one were available in the other, and vice versa. With this in mind, we will have to fall back to other factors such as the most reliable, proven and active projects. As mentioned, we would choose functional stability over endless features that we will never use and that add to the projects fingerprint... I understand that all three projects are forks from OpenSER, people would naturally like to know what differentiates one from the other. Thanks in Advance, Nick Khamis Toronto Hydro Telecom

Kamailio presentations at Cluecon 2011
by Daniel-Constantin Mierla 15 Aug '11

15 Aug '11

Hello, I uploaded my slides presented at Cluecon 2011, last week in Chicago. In the first part the focus was on what has been happening in the last year around the project, on the second part showing some example of using it to secure VoIP networks. The PDF is available at: * http://asipto.com/u/42 Alexandr Dubovikov presented the recently announced Homer project which turns Kamailio in a scalable capturing system for SIP traffic, the slides for this talk are available at: * http://www.kamailio.org/events/2011-Cluecon/AD-Homerv2.pdf Stefan Wintermeyer presented Gemeinschaft 4 project, which is targeting to offer a very secure out-of-the-box IP PBX system, using Kamailio as one of the major components. The slides will be available in the near future (I will update the lists) -- he will present the same topic at 10 years SER conference in Berlin: * http://sip-router.org/10-years-ser/ Cheers, Daniel

freezing for major release 3.2.0
by Daniel-Constantin Mierla 15 Aug '11

15 Aug '11

Hello, based on the last devel IRC meeting, the next major release should happen sometime by end of September, therefore we should freeze the development and go into testing phase about one month before. I propose Monday, August 22, the day to freeze development for version 3.2.0. By then, I hope every developer will be able to push to master branch what he/she wants to have in 3.2.0. Write here to mailing lists if you thing about alternatives. The very good side of 3.2.0 is that we didn't need to touch much the core and main modules, meaning we have a solid tested foundation, further testing should be focused on the new modules and the other enhancements. Cheers, Daniel -- Daniel-Constantin Mierla -- http://www.asipto.com Kamailio Advanced Training, Oct 10-13, Berlin: http://asipto.com/u/kat http://linkedin.com/in/miconda -- http://twitter.com/miconda

Wrong formatting of Request URI
by Mino Haluz 15 Aug '11

15 Aug '11

Hi, my kamailio is sometimes receiving ruri from remote clients which I assume are not right formatted. For ex.: sip:user@kamailio=3Buser=3Dphone Is there any mechanism which could transform this into something readable for kamailio or do I have to simply cut off everything after the host name of the RURI ?

pua_xmpp questions
by laura testi 13 Aug '11

13 Aug '11

Hi all, we are trying to setup a kamailio presence server in SIP/SIMPLE domain to interwork with XMPP domains including the GTalk (see the config below). The architecture is like this: - SIP/SIMPLE server: kamailio3.14 with full configuration with XCAP integration - XMPP Gateway: another kamailio server + ejabberd server - component mode - xmpp moduleL: outbound proxy to the Kamailio SIP/SIMPLE server - pua_xmpp: no outbound proxy? - XMPP server: ejabberd The users from XMPP domain can add the SIP account and see the presence of the SIP users, but not vice versa. The chat from both directions works fine. in the Presence Server, we have configured the kamailio with XCAP integration. We have the following doubts: - does pua_xmpp/pua modules need the xcap integration for the presence integration with xmpp domains? because to use xcap for presence authorization rules, it needs the sip clients support the xcap - does pua_xmpp/pua support xcap? otherwise how to works? - in case of multiple SIP/SIMPLE presence server, how we can configure the server_address of pua_xmpp and presence parameter in xmpp gw? Can you help us to clarify the doubts please? Many thanks in advanced! Best Regards, Laura PS: following are the main configuration of the xmpp GW: --------------------------------------------------------------------------------------------- ... modparam("xmpp", "domain_separator", "*") modparam("xmpp", "backend", "component") modparam("xmpp", "gateway_domain", "<mygwdomain>") modparam("xmpp", "xmpp_domain", "<mygwdomain>") modparam("xmpp", "xmpp_host", "127.0.0.1") modparam("xmpp", "xmpp_password", "secret") modparam("xmpp", "outbound_proxy", "<my oubound proxy uri>") modparam("pua", "outbound_proxy", "<my outbound proxy uri>") modparam("pua", "update_period", 60) modparam("pua", "default_expires", 1200) modparam("presence", "server_address", "<my presence server uri>") modparam("pua_xmpp", "server_address", "<my presence server uri>") route{ route(REQINIT); t_check_trans(); if (uri =~ "sip:.+@.*<myxmppdomain>") { route(PRESENCE); if ($rU==$null) { # request with no Username in RURI sl_send_reply("484","Address Incomplete"); exit; } route(CHAT); } xlog("L_INFO", "*** xmpp: unhandled message type\n"); t_reply("503", "Service unavailable"); return; } ... route[CHAT] { if(!is_method("MESSAGE")) return; if (!t_newtran()) { sl_reply_error(); exit; } xlog("L_INFO", "*** xmpp-handled MESSAGE message."); if ($cT=~"^text/plain") { if (xmpp_send_message()) { t_reply("200", "Accepted"); } else { t_reply("404", "Not found"); } } else { xlog("L_INFO", "*** xmpp-handled MESSAGE, ignoring not text messages"); t_reply("200", "Accepted"); } t_release(); exit; } route[PRESENCE] { if(!is_method("PUBLISH|SUBSCRIBE|NOTIFY")) return; # create new transaction to catch retransmissions if (!t_newtran()) { sl_reply_error(); exit; } if( is_method("NOTIFY")) { xlog("L_INFO", "*** xmpp-handled NOTIFY message."); if(pua_xmpp_notify()) t_reply("200", "OK"); t_release(); exit; } else if( is_method("SUBSCRIBE")) { xlog("L_INFO", "*** xmpp-handled SUBSCRIBE message.\n"); handle_subscribe(); if($(hdr(Event))== "presence") { pua_xmpp_req_winfo("$ruri", "$hdr(Expires)"); } t_release(); exit; } else if(is_method("PUBLISH")) { handle_publish(); t_release(); exit; } } ...
