Load balancer using dispatcher / BYE relaying
by Ariel Wainer 22 Apr '13

22 Apr '13

StartFragmentHi, I'm new to Kamailio and I'm trying to setup a load balancer using Kamailio 4.0 and rtpproxy, to balance between 2 asterisk servers that provide an IVR service. I've followed several guides, and so far it seems to work along with rtpproxy, except it is not sending the BYE message back to asterisk, and the call never finishes from the asterisk POV. Let me describe the test scenario: I have the following: IP phone: 192.168.200.183 PBX: 192.168.200.3 Kamailio: 192.168.200.132 IVR1: 192.168.200.160 IVR2: 192.168.200.161 >From the IP phone which is registered on the PBX, I initiate a call to exten 800, PBX forwards it to 1234@192.168.200.132:5060 and Kamailio dispatches it to one of the two IVR in round-robin. I'm testing this way and not calling directly to Kamailio because in the production enviroment, calls will be coming from outside. Attached you will find the Kamailio configuration. Packet capture made at the Kamailio host, where you can see the BYE package from the PBX (first one on line 24) but no BYE package sent to the IVRs is here: http://cringer.3kh.net/web/misc/sip.cap Please let me know if I ommited any important detail of my setup and thanks in advance. Best regards. -- Ariel Wainer

[SER-Users] debug: again.
by Victor V. Kustov 22 Apr '13

22 Apr '13

Hi all! Still same problem: i don't see debug messages. OS: FreeBSD 9.1 stable, fresh git Kamailio version. In present moment just debugger.so with config trace work as expected. Option "debug=X" seems has no effect at all. I saw debug logs in maillist. Maybe I make something wrong? I never see simulary strings in logs: debug: DEBUG: <core> [forward.c:511]: orig. len=460, new_len=483, proto=1 debug: DEBUG: <core> [usr_avp.c:639]: DEBUG:destroy_avp_list: destroying list 0xb323c178 debug: DEBUG: <core> [usr_avp.c:639]: DEBUG:destroy_avp_list: destroying list (nil) debug: DEBUG: <core> [usr_avp.c:639]: DEBUG:destroy_avp_list: destroying list (nil) debug: DEBUG: <core> [usr_avp.c:639]: DEBUG:destroy_avp_list: destroying list (nil) debug: DEBUG: <core> [usr_avp.c:639]: DEBUG:destroy_avp_list: destroying list (nil) debug: DEBUG: <core> [usr_avp.c:639]: DEBUG:destroy_avp_list: destroying list (nil) debug: DEBUG: <core> [receive.c:280]: receive_msg: cleaning up -- SY, Victor JID: coyote(a)bks.tv JID: coyote(a)bryansktel.ru I use FREE operation system: 3.8.4-calculate GNU/Linux

When to use t_newtran/t_release?
by Yufei Tao 22 Apr '13

22 Apr '13

Hi, I've been using the default cfg file as a starting point and added my stuff on top. But I don't think I understand the use of t_newtran/t_release and when they should be used. Read the documentation but still not clear. For example, for presence: t_newtran is called before handle_publish/subscribe and t_release called afterwards. And in route[LOCATION], t_newtran is called before sending 4xx responses. Could someone help explain please what they do and when they should be used please? Thank you!

Hi, I'll do today this noon a regular maintenance of www.kamailio.org. I don't expect any big outtages, the webserver could be maybe for a few seconds not available due to some restarts. I'll announce when the maintenance is finished. Best regards, Henning

Possible memory leak in parse_pai.c
by Tais Plougmann Hansen 22 Apr '13

22 Apr '13

Hi, I'm seeing a possible leak in parsing the P-Asserted-Identity, and possibly P-Preferred-Identity headers in kamailio-3.3.4. I have a server running in which one thread has currently most of the 8 MB private memory allocated. At restart qm_sums reports parse_pai.c as sitting on most of the memory: Apr 16 16:38:58 gws1 /usr/sbin/kamailio[9398]: INFO: qm_status: heap size= 8388608 Apr 16 16:38:58 gws1 /usr/sbin/kamailio[9398]: INFO: qm_status: used= 5369240, used+overhead=6417216, free=1971392 [...] Apr 16 16:39:03 gws1 /usr/sbin/kamailio[9398]: INFO: qm_sums: count= 6198 size= 4721776 bytes from <core>: parse_pai.c: parse_pai_header(58) I am currently using the header through $ai for xlog statements, the accounting module and a validity check (if (!($(ai{uri.user}) =~ "^\+[1-9]+")) {...}). >From digging through the logs it could seem like this happens when using $ai in the accounting module. I'll try removing it from accounting (log_extra) and see if it stops leaking. -- Tais Plougmann Hansen OSD Consulting ApS osd.dk Tel: +45 78101078 CVR: DK31332737

Rtpproxy - IPv4/v6 Translation and earlier removing of session
by Jakub Hrabovský 22 Apr '13

22 Apr '13

Hi, I started working on IPv4/IPv6 Translation issue in Kamailio by using rtpproxy as Media relay last year in my Bachelor-project. I solved the trouble with Translation between IPv4 and IPv6 clients, where IPv4 client used public IPv4 address. Now I am working on the issue, where IPv4 client uses private IPv4 (is behind NAT in local network), so I have to provide IPv4/v6 and NAT for all messages in one call. My topology consists of: Kamailio 3.3.4 - SIPproxy (supports IPv4/IPv6, public IPv4 and IPv6 addresses) - makes NAT translation, works as SIPoutbound proxy and communicates with rtpproxy (v1.2.1), Kamailio 3.3.4 - SIPprotocol GW (== SIP bridge) - translates IPv4 messages to IPv6 (and IPv6 to IPv4), uses other rtpproxy, has public IPv4 and IPv6 addresses + only IPv4 and only IPv6 clients (Linphone v3.5.2) I assume, that both (IPv4 and IPv6) clients are in the same SIP domain. I solve IPv4-IPv6 translation so, that each message from IPv6 client goes to SIP proxy and (if needed) is forwarded to SIP Protocol GW. Translated medssage is then forwarded back to SIP proxy and from that to callee. Here i have some problems: -1.) IPv6 client doesnt respond to invites from IPv4 client. The messages are ignored at IPv6 client. -2.) Rtpproxy on the machine with SIP protocol gateway (which provides IPv4/v6 translation) removes session earlier than I need (usually after 30 seconds of call) and the result is call break. this issue doesnt appear for rtpproxy on SIP proxy. I dont know what causes this behavior, if it is only in some parameters, witch i have to set, or it is bug in rtpproxy or .... Here I get config files of topology entities: ----------------------------------------------------------------------------------------------------------------------------- config file for SIP proxy: ----------------------------------------------------------------------------------------------------------------------------- #!KAMAILIO #

UAC example
by Moacir Ferreira 22 Apr '13

22 Apr '13

Hi community, I will start testing the UAC module. Does anyone have a simple UAC configuration that could share with me? Also, for small (less than 500 users) deployments, would you recommend Kamilio UAC as the solution for giving PSTN access via VoIP providers or would you recommend Asterisk, SEMS, etc.? My intention is to host the solution on a single server. Thanks, Moacir

Problem accessing git repository
by Mikko Lehto 22 Apr '13

22 Apr '13

Hi Yesterday I got "fatal: read error: Connection reset by peer" to my "git pull" command. I thought it was only temporary network error, but same problem still exist today. I can however access other remote git repositories succesfully from the same host. --- #sip-router 10.58 < mslehto> hmm... I get "Connection reset by peer" to git fetch command 10.59 < mslehto> propably local issue if you just updated master branch succesfully 11.10 < iZverg> git pull 11.11 < iZverg> # git pull 11.11 < iZverg> Already up-to-date. 11.11 < iZverg> i think all ok with server 13.07 < mslehto> I don't get it .pcap dumps shows some git traffic to git.sip-router.org, but finally I get TCP RST 13.07 < mslehto> I have remote.origin.url=git://git.sip-router.org/sip-router 13.08 < mslehto> seems to be same as in http://kamailio.org/wiki/install/devel/git 13.13 < iZverg> url = git://git.sip-router.org/sip-router 13.13 < iZverg> Already up-to-date. --- I think this is not local issue, any pointers what I should troubleshoot next? UPDATE: I am able to get source code via "git clone" to fresh directory with no errors, confusing. -- Mikko
