Via branch parameter in end2end ACK
by Francesco Castellano 19 May '11

19 May '11

Dear sirs, using version 3.1.3 (kamailio flavour), I noticed that the Via inserted by the proxy, relaying an end2end ACK, contains a branch parameter equal to 0 (with no magic cookie prefixed). No misbehaviour followed, but I was wonder about the reason for this behaviour and whether it can be a fault of my config: route { [some checks] if (!is_method("REGISTER|MESSAGE|PUBLISH")) { record_route(); } else if (is_method("REGISTER")) { route(HANDLE_REGISTER); exit; } if (loose_route()){ if (!has_totag()){ if (!is_method("ACK")){ send_reply("403", "Preset Route Set Not Allowed"); } exit; } t_check_trans(); if (is_method("ACK")){ if ($du == $null){ handle_ruri_alias(); } if (isflagset(T_UAC_NATED) && isflagset(T_UAC_USER)){ add_contact_alias(); } remove_hf("Proxy-Authorization"); t_relay(); exit; } } [other processing] } Here's an example for the forwarded ACK: U 2011/05/17 15:05:49.392201 proxy_1_ip:5060 -> location_callee_ip:5060 ACK sip:5303838@192.168.130.169;user=phone SIP/2.0. Record-Route: <sip:proxy_1_ip;lr=on;ftag=a2z0myc9r6>. Via: SIP/2.0/UDP proxy_1_ip;branch=0. Via: SIP/2.0/UDP proxy_0_ip;rport=5060;branch=0. Via: SIP/2.0/UDP 192.168.130.171:2048;received=location_caller_ip;branch=z9hG4bK-pud4cfiz8vsh;rport=4791. From: "cento tondo" <sip:100@proxy_0_hostname>;tag=a2z0myc9r6.

Content-Length: 0. . where proxy_1 does force_rport and record_route() on ACK too, and proxy_0 does not. Both proxies run the same version, and a similar ACK script processing.

ACK to 486 is not being proxied
by Carl Wagner 19 May '11

19 May '11

Hi, I have Kamailio set up to act as a proxy and load balancer. Most things are working correctly but for some reason I can't get Kamailio to proxy an ACK to a 486 Busy. I assume that it is something wrong that I have done in the kamailio.cfg file but I am not seeing it. Does the t_check_trans() return false because the call state is Busy? Please let me know if you need other logs or information.

redirect implementation with dispatcher
by alex pappas 19 May '11

19 May '11

Dear all, I'm trying to create a service which when a call reach Kamailio, this call get's a number of gateways in round robin mode and from them I create uri and append_branches. The all scenario works fine except that I don't get from Dispatcher the round robin mode. Is is the way I ask Dispatcher and i don't get the results I need. In other scenarios Dispatcher works fine. The other thing is that I tried the random alg of Dispatcher and that works. I'm trying to understand what I'm doing wrong and why random alg works but round robin not. I'm attaching my code if anyone has an idea of what I'm doing wrong. Thank you Alex *Scenario description:* * Call enter --> Dialplan (Here if has a match get the attributes which is a list of dispatcher gw group in the form of 100.101.#) --> Dispatcher (For every dispatcher gw group appnd the branch) --> Redirect the call* route[TEST] { if(dp_translate("$avp(s:lcr_id)", "$rU/$rU")) { $var(i) = 0; while($(var(dpattrs){s.select,$var(i),.})!="#") *#attr example is gw group of disptcher in order 100.101.# or in my scenario is 200.# which in Dispatcher is 2 gw* *10.0.0.2 and 10.0.0.3* { $avp(s:disp_dstgrp) = $(var(dpattrs){s.select,$var(i),.}{ s.int}); if(ds_select_domain("$avp(s:disp_dstgrp)", "4")) { append_branch(); revert_uri(); $avp(s:disp_dstgrp) = "null"; } $var(i) = $var(i) + 1; # for the while loop } ####################### REDIRECTION ##################### sl_send_reply("300", "Multiple Choice"); ######################################################### exit; } else { xlog(" ----- No routing found for this call -----"); } }

Kamailio 1.5 acc on glare BYE
by Tobias Lindgren 18 May '11

18 May '11

Hi all! I have a short question with regards to how the acc module handles (or rather logs) BYEs. As I understand, a BYE followed by an 200 OK will be logged by Kamailio's acc module. This works perfectly fine in my set up. However, one of the carriers that I'm using sometimes respond with a "487 Request Terminated" to BYE messages, stating that "Glare Bye condition encountered". I'm not really sure why this occurs at my carriers', but whenever this happens, acc does not log the BYE message. To my question; what happens in the acc module if sip_code > 200 is received? And, should these BYE's be logged, even though the code is 487? I'm on Kamailio 1.5 with acc logging to MySQL. Br, /Tobias

report from linuxtag, presentations
by Henning Westerholt 17 May '11

17 May '11

Hello, just to give you a quick feedback about the this year linuxtag - it was overall a really nice event in my opinion. A lot of people passed by at our booth to discuss about Kamailio and VoIP in general. Carsten Bock presented about our new IMS extensions, Andreas Granig showed a demo of their new kamailio based carrier product. I hope that we can provide some photos of the event soon. We've did two presentations, one about "Linux at 1&1" including a Kamailio part on wednesday, and Carsten did two "FastForward" talks on wednesday and thursday. I've uploaded the slides to our webserver: http://www.kamailio.org/events/2011-linuxtag/linux-at-1and1.pdf http://www.kamailio.org/events/2011-linuxtag/kamailio-quick.pdf Also interesting, the German Federal Office for Information Security (BSI) presented the upcoming "Gemeinschaft" PBX project version 4 that will use Kamailio (and Freeswitch). They sponsor the project, it aims to provide a secure, scalable and easy to use open source PBX plattform. Best regards, Henning

Does t_newtran() behave different than in Kamailio 1.5?
by Iñaki Baz Castillo 17 May '11

17 May '11

Hi, as Kamailio 1.5 TM documentation states, changes to transaction (adding headers, filling AVP's and so) after calling t_newtran() are not saved into the transaction: http://kamailio.org/docs/modules/1.5.x/tm.html#id2510920 NOTE that the changes on the request that are made after this function call will not be saved into transaction!!! However in 3.X TM documentation such note is not present: http://kamailio.org/docs/modules/devel/modules/tm.html#t_newtran So, does 3.X behave different and changes after t_newtran are added to the transaction or not? Thanks a lot. -- Iñaki Baz Castillo <ibc(a)aliax.net>

core in dialog module
by Anton Roman 17 May '11

Hi all, we got a core in dialog module. We are using kamailio 3.1.2. Below you can find a full backtrace from the dump and the Kamailio compilation options. Please, if you need further information don't hesitate to ask me for it. I can't precise the situation when it is generated because we have a quite high load in this server. Thanks in advance.
