Fwd: kamailio with evapi crashing on high volume

by Jayesh Nambiar

Hello Daniel, Just a quick update on this. After running from the 5.1 branch twice it happened that Server became unresponsive. It never crashed and on forceful shutdown it only generated a core with shutdown routine. Here is what the syslog contained off while the calls were being sent to kamailio but kamailio was not processing any calls: Sep 22 16:09:04 triviamedia /usr/local/kamailio/sbin/kamailio[16006]: CRITICAL: <core> [core/mem/q_malloc.c:502]: qm_free(): BUG: freeing already freed pointer (0x7fcd23ce5648), called from tm: h_table.c: free_cell_helper(235), first free tm: h_table.c: free_cell_helper(235) - aborting Sep 22 16:09:04 triviamedia /usr/local/kamailio/sbin/kamailio[16006]: CRITICAL: <core> [core/mem/q_malloc.c:502]: qm_free(): BUG: freeing already freed pointer (0x7fcd24a38ea8), called from tm: h_table.c: free_cell_helper(234), first free tm: h_table.c: free_cell_helper(234) - aborting Sep 22 16:09:04 triviamedia /usr/local/kamailio/sbin/kamailio[16006]: CRITICAL: <core> [core/mem/q_malloc.c:502]: qm_free(): BUG: freeing already freed pointer (0x7fcd23ce5648), called from tm: h_table.c: free_cell_helper(235), first free tm: h_table.c: free_cell_helper(235) - aborting Sep 22 16:09:04 triviamedia /usr/local/kamailio/sbin/kamailio[16006]: CRITICAL: <core> [core/mem/q_malloc.c:502]: qm_free(): BUG: freeing already freed pointer (0x7fcd24a38ea8), called from tm: h_table.c: free_cell_helper(234), first free tm: h_table.c: free_cell_helper(234) - aborting Sep 22 16:09:04 triviamedia /usr/local/kamailio/sbin/kamailio[16006]: CRITICAL: <core> [core/mem/q_malloc.c:502]: qm_free(): BUG: freeing already freed pointer (0x7fcd23ce5648), called from tm: h_table.c: free_cell_helper(235), first free tm: h_table.c: free_cell_helper(235) - aborting Sep 22 16:09:04 triviamedia /usr/local/kamailio/sbin/kamailio[16006]: CRITICAL: <core> [core/mem/q_malloc.c:502]: qm_free(): BUG: freeing already freed pointer (0x7fcd24a38ea8), called from tm: h_table.c: free_cell_helper(234), first free tm: h_table.c: free_cell_helper(234) - aborting Sep 22 16:09:04 triviamedia /usr/local/kamailio/sbin/kamailio[16006]: CRITICAL: <core> [core/mem/q_malloc.c:502]: qm_free(): BUG: freeing already freed pointer (0x7fcd23ce5648), called from tm: h_table.c: free_cell_helper(235), first fre And here's the "bt full" of the core file: [New LWP 16003] Cannot access memory at address 0x7fcd64e1a148 Cannot access memory at address 0x7fcd64e1a140 Failed to read a valid object file image from memory.

Forcing outbound transport to TCP

by Ivan Ribakov

I’m new to Kamailio and currently evaluating it’s capabilities. One of the things I would like to be able to do is to change outbound message transport based on some dynamic logic. Kamailio setup: I’m running on a setup from this guide - http://kamailio.org/docs/tutorials/5.1.x/kamailio-install-guide-git/ <http://kamailio.org/docs/tutorials/5.1.x/kamailio-install-guide-git/> and using default configuration file. In a basic scenario of one2one call, I was able to make Kamailio to forward INVITE to callee over TCP by issuing a REGISTER request with “transport=tcp” parameter. Although it worked, as far as I understand that means all communication with the callee will be happening over TCP. I would like to be able to change transport dynamically so looking for a way to do that from config file. I tried modifying $ru/$du in the following manner, but it didn’t seem to work. # default config content if (is_method("INVITE")) { setflag(FLT_ACC); # do accounting # added to try to force TCP transport $du = $du + ";transport=tcp"; } Any pointers as to how can I modify the outbound message transport? Do I need to use some extra modules or can it be achieved with a basic setup? Thanks in advance, Ivan

Registrar Module

by Dan Quinney

Hi, So, route[REGISTRAR_1] will, when the max_contacts is reached, reply to the endpoint with a 503 error containing a "P-Registrar-Error: Too many registered contacts" header - this seems wrong to me so I've tried to work around it with route[REGISTRAR_2] which returns the right response, but, also writes "INFO: registrar [save.c:615]: test_max_contacts(): too many contacts for AOR" to the log file, which is messy. Does anyone have any pointers for doing this better? Thanks, Dan route[REGISTRAR_1] { if ( is_method("REGISTER") ) { if(isflagset(FLT_NATS)) { setbflag(FLB_NATB); setbflag(FLB_NATSIPPING); } if ($avp(maximum_contacts) != $null) { $xavp(reg=>max_contacts) = $avp(maximum_contacts); } save("location"); } return; } route[REGISTRAR_2] { if ( is_method("REGISTER") ) { if(isflagset(FLT_NATS)) { setbflag(FLB_NATB); setbflag(FLB_NATSIPPING); } if ($avp(maximum_contacts) != $null) { $xavp(reg=>max_contacts) = $avp(maximum_contacts); } save("location", "0x02"); switch ($retcode) { case -1: sl_send_reply("500", "Server Internal Error"); exit; case -2: sl_send_reply("403", "Forbidden"); exit; }; sl_send_reply("200", "OK"); } return; }

Problem with replicating dialogs using DMQ

by Jan Hazenberg

Hello, I'm trying to replicate active dialogs using the DMQ module. I see the dialogs on the other nodes but it generates a error message in the logs on all the nodes: Sep 27 10:17:31 sip04 /usr/sbin/kamailio[27367]: CRITICAL: dialog [dlg_timer.c:130]: insert_dlg_timer(): Trying to insert a bogus dlg tl=0x7efdca1bebf8 tl->next=0x7efdca14cb80 tl->prev=0x7efdca14cb80 Sep 27 10:17:31 sip04 /usr/sbin/kamailio[27367]: CRITICAL: dialog [dlg_dmq.c:309]: dlg_dmq_handle_msg(): Unable to insert dlg timer 0x7efdca1beb98 [2643:3725] Even with the timeout_avp option disabled i still see the error messages. I tested this on kamailio 5.0.3 and 5.1.3 with the same results.

registrar lookup with different URI

We have the extension & domain in variables, but the RURI is ext@ip-of-server, e.g. 200(a)1.1.1.1<mailto:200@1.1.1.1>, while we want to perform the lookup for 200(a)somedomain.tld<mailto:200@somedomain.tld>. We have somedomain.tld in a header, so we have it in a variable. However, if we perform the lookup like this (using Python module): lookup_result = KSR.registrar.lookup('location') We get a negative result, and the debug logs show that it tries to locate 200(a)1.1.1.1<mailto:200@1.1.1.1> - which makes sense. So according to docs you can specify an URI, however when I do this: lookup_result = KSR.registrar.lookup('location' '200(a)somedomain.tld') lookup_result is "False" and the function is not executed, according to docs because it cannot obtain the parameters for this function. How can we force the registrar module to lookup a different user?

Dialog timout reset when receiving a re-INVITE

by jenus＠cyberchaos.nl

Hello, I have a issue with setting the dialog timeout for a call. It works fine until i receive a re-INVITE. The re-INVITE seems to reset the dialog timeout back to the default value configured in the module parameters (7200 in my case). I use "dlg_set_timeout("900");" to set the timeout to 900 seconds. When i receive a re-INVITE i see the following in the debug logs: DEBUG: dialog [dlg_handlers.c:647]: get_dlg_timeout(): invalid AVP value, using default timeout This happens even with the "timeout_avp" module parameter disabled. I'm running kamailio 5.1.3. Thanks, Jan

kamailio rtp connection

by Pieter Muller

Good day all I hope Im on the right place to ask the question. Im a newbie to kamailio and have a little problem understanding how to set kamailio correctly. Scenario: VoIP Supplier (IP:161.161.252.20{Private Net}) à Connect via routing to Kamailio Server(155.155.16.2 eno2{private Net}),Kamailio Server(187.221.197.252 eno1{public facing})àconnect to PBX(public IP set in dispatcher) à connect to RTP server(Public IP) Now the problem is that if you call in Number(a)161.161.252.20 <mailto:Number@161.161.252.20> is send to kamailio, kamailio then sends it down to dispatcher IP and that PBX responds directly back via rtp server to 161.161.252.20. The 161.161.252.20 IP is private and cannot be reached from the cloud and vice versa . How do I get kamailio to be the middle man between 161.161.252.20 and RTP server(all traffic must go via the kamailio server) Is there specific modules I must load. Im running Kamailio 4.4 Any help would be muchly appreciated. Regards Pieter

Important: new module exports interface

by Daniel-Constantin Mierla

Hello, as a result of collaborative work at Kamailio Developers Meeting, we succeeded to merge the two existing module exports interface (one for kamailio modules and the other one from ser modules) in a single one. All public modules were updated, but if you have any private module then you have to update as well in order to get it compiled with the latest master. Just look at one of the modules (e.g., sl is a good option) and all the fields in mod exports structure have comments with their meaning. In short: we removed unused fields for statistics, mi commands and extra-processes (from kamailio old interface) and oncancel (from ser old interface), kept the rpc exports from ser interface and pv exports and dlopen flags from kamailio interface. The other fields were common in both interfaces, but be aware that order was also changed. If you have a module implementing the old ser interface, you also need to add the free_fixup_field in functions exports tructure -- you can just set it to 0. With this we have now a single mod exports interface in all modules, the core is also cleaner as we got rid of the various compatibility layers.
