reload to memory is much slower and has problms after upgrade to 3.3.2 and using mem_join=1
by Uri Shacked 05 Dec '13

05 Dec '13

Hi, I am using MTREE and DIALPLAN modules to load lots of info to kamailio. (6 million rows). When kamailio was running with 3.2.1 (no mem_join=1 option), the used size was increasing but the process of loading the data was fast eanough. I upgraded to 3.3.2 and set mem_join=1. Now the loading process take about 10 time longer and sometimes stops kamailio from responding to traffic. Any ideas? Thanks, Uri

Problem with 4.0 nightlies and IMS - sem_post undefined
by Barry Flanagan 21 Nov '13

21 Nov '13

Hi I am trying to run the Ubuntu nightlies from http://deb.kamailio.org/kamailiodev-nightly and loading the p-cscf config files. Things were working fine while I was on the 20130110 nightlies, but when I upgraded to 20130122 I get the following errors. Any have an idea why sem_post is undefined and how to fix this? 0(1980) ERROR: <core> [sr_module.c:572]: ERROR: load_module: could not open module </usr/lib64/kamailio/modules/ims_registrar_pcscf.so>: /usr/lib64/kamailio/modules/ims_registrar_pcscf.so: undefined symbol: sem_post 0(1980) ERROR: <core> [sr_module.c:572]: ERROR: load_module: could not open module </usr/lib64/kamailio/modules/cdp.so>: /usr/lib64/kamailio/modules/cdp.so: undefined symbol: sem_post 0(1980) ERROR: <core> [sr_module.c:572]: ERROR: load_module: could not open module </usr/lib64/kamailio/modules/ims_qos.so>: /usr/lib64/kamailio/modules/ims_qos.so: undefined symbol: sem_post Thanks -Barry Flanagan

EOF Error in pass_fd

Hello List.

TLS questions
by Fabian Borot 20 Nov '13

20 Nov '13

Hi, please help me out with these questions: Is it possible to configure kamailio to use different certificates, one per peer? Do we just add them to the same "calist.pem" file? Is is possible to configure kamailio to accept a certificate from another device? I mean instead of Kamailio creating the certificate/key and give it to customer/provider. If that is the case, do we also add it to the "calist.pem" file as well? If all the above is true, what happens when the certificates have different expiration dates? thank you very much

BUG? - Dialog module timeout BYE is not ok.
by Uri Shacked 11 Nov '13

11 Nov '13

Hi, Following this issue, and the issue "BYE dialog timeout bad syntax" from Julia. I have 2 kamailio servers. srv1 creates a dlg_timeout BYE and sends it to srv2 that forwards the BYE to the next sip server (some other server...). I can definitely see that the BYE that is being forward is malformed. The TO header info is not complete (the port section for example). When a "normal" bye is received from srv1 (not dlg_timeout) all works fine. One thing that i do in this scenario, on srv2 i use uac_replace() on the TO header. So, it is OK that the final destination is different (i do translations). I attached the BYE from both servers. Any ideas? Thanks, Uri You probably meant the To and From headers, I'm guessing. Yeah, as long as there is no display name component, URIs in headers like that don't have to go in <>s. The way Kamailio sends it is grammatically valid, per RFC 3261. The user agents are at fault for not understanding it correctly. Alex Balashov <abalashov at evaristesys.com<http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users>> wrote: >*"BYE headers"?

Memory leak in 3.3.4
by David Cunningham 17 Oct '13

17 Oct '13

Hello, We're running a Kamailio 3.3.4 system, and Kamailio is slowly using more and more memory. Over a couple of weeks it will run out of system memory. We tried to enable memory debugging doing the following, but it resulted in Kamailio not responding to any SIP packets. Would anyone have advice please on how to debug the situation? 1. In Makefile.defs set MEMDBG to 1 and recompile Kamailio. 2. In kamailio.cfg add the line: #!define DEBUG_MEMORY 1 While this was running and Kamailio didn't respond to packets, it logged lots of lines like this: Jul 22 21:32:22 hostname kamailio: : <core> [mem/q_malloc.c:369]: qm_malloc(0x4000e008, 128) called from <core>: cfg.lex: addstr(1438) Jul 22 21:32:22 hostname kamailio: : <core> [mem/q_malloc.c:413]: qm_malloc(0x4000e008, 128) returns address 0x40048918 frag. 0x40048900 (size=128) on 1 -th hit Jul 22 21:32:22 hostname kamailio: : <core> [mem/q_malloc.c:369]: qm_malloc(0x4000e008, 128) called from <core>: cfg.lex: addstr(1438) Jul 22 21:32:22 hostname kamailio: : <core> [mem/q_malloc.c:413]: qm_malloc(0x4000e008, 128) returns address 0x400489c8 frag. 0x400489b0 (size=128) on 1 -th hit Thanks in advance, -- David Cunningham, Voisonics http://voisonics.com/ USA: +1 213 221 1092 UK: +44 (0) 20 3298 1642 Australia: +61 (0) 2 8063 9019

unregister user when kamailio looses TCP connection.
by Vitaliy Aleksandrov 24 Sep '13

24 Sep '13

Hello, I've made a patch to kamailio-4.0.3 which removes stale registration when kamailio looses an incoming tcp connection. Of course this patch needs more work. Since the are no direct references between user location contacts and tcp connections callback function uses linear search through the whole location table using received field as a key. Can anybody more experienced in kamailio internals check if I chose the right place to get information about lost tcp connections ? Another thing I wanted to ask is maybe somebody can suggest a better way to tie a tcp connection to the user location information without complicating "usrloc" module by any heavy data structures. If anybody else except me need this It would be great to fix known problems and add it to kamailio.

Pseudo-variables and branches
by Steve Davies 13 Sep '13

13 Sep '13

Hi - Can someone help me understand how pseudo-variables interact with branches? I've written this logic in my failure route to do a reroute of calls if the primary destination fails: if ( is_method("INVITE") && !t_check_status("407") && ($rd != "127.0.0.1") ) { # Maybe should also check its not just a Busy or similar xlog("L_NOTICE","SLD: INVITE failed $rm ($mt / $rs $rr): $ci::$ft; try via asterisk instead\n"); append_branch("sip:$rU@127.0.0.1:5070"); send_reply("181", "Rerouting call via local failover"); $avp(senttoast) = 1; if (!t_relay()) { sl_reply_error(); # or reply_error ? } I'm trying to check if the call was already rerouted - by looking at $rd. But in fact I find that $rd keeps the domain from the ORIGINAL invite even if the call that just failed was the one to 127.0.0.1:5070 . So I'm obviously missing something about how pseudo-variables interact with the branching etc. Thanks, Steve -- Steve Davies: Technical Director, Connection Telecom (Pty) Ltd Email is preferred, but: Phone: 0878200200
