Kamailio 4.2 crash
by Rahul MathuR 08 Dec '14

08 Dec '14

Hello, I have recently moved some traffic to kamailio-4.2 (installed on a seperate box) and it crashes quite often. Below is the backtrace of the core files - <CORE#1> (gdb) bt #0 0x00000033d8c32635 in raise () from /lib64/libc.so.6 #1 0x00000033d8c33e15 in abort () from /lib64/libc.so.6 #2 0x000000000049add5 in sig_alarm_abort (signo=14) at main.c:689 #3 <signal handler called> #4 0x00000033d8ce50c7 in syscall () from /lib64/libc.so.6 #5 0x00007f7ca2ea0a1e in futex_get (lock=0x7f7ca3334388) at ../../mem/../futexlock.h:110 #6 0x00007f7ca2ea1e99 in remove_dialog_timer (tl=0x7f7ca3384c98) at dlg_timer.c:168 #7 0x00007f7ca2e83e9b in destroy_dlg (dlg=0x7f7ca3384c40) at dlg_hash.c:357 #8 0x00007f7ca2e84e19 in destroy_dlg_table () at dlg_hash.c:438 #9 0x00007f7ca2e50b89 in mod_destroy () at dialog.c:773 #10 0x000000000058dfd5 in destroy_modules () at sr_module.c:818 #11 0x0000000000499ad3 in cleanup (show_status=1) at main.c:564 #12 0x000000000049b096 in shutdown_children (sig=15, show_status=1) at main.c:706 #13 0x000000000049d66c in handle_sigs () at main.c:797 #14 0x00000000004a4e57 in main_loop () at main.c:1757 #15 0x00000000004a8a43 in main (argc=2, argv=0x7fff58d21368) at main.c:2609 (gdb) quit <CORE#2> (gdb) bt #0 0x00007f7ca2ea22d7 in update_dlg_timer (tl=0x58, timeout=10) at dlg_timer.c:203 #1 0x00007f7ca2e824f3 in dlg_clean_run (ti=44865910) at dlg_hash.c:253 #2 0x00007f7ca2e566fc in dlg_clean_timer_exec (ticks=44865910, param=0x0) at dialog.c:1250 #3 0x00000000005f93e8 in fork_sync_timer (child_id=-1, desc=0x7f7ca2eb3a71 "Dialog Clean Timer", make_sock=1, f=0x7f7ca2e566e3 <dlg_clean_timer_exec>, param=0x0, interval=90) at timer_proc.c:232 #4 0x00007f7ca2e50476 in child_init (rank=0) at dialog.c:730 #5 0x000000000058e385 in init_mod_child (m=0x7f7ca8c09eb8, rank=0) at sr_module.c:930 #6 0x000000000058e0c0 in init_mod_child (m=0x7f7ca8c0b000, rank=0) at sr_module.c:927 #7 0x000000000058e68f in init_child (rank=0) at sr_module.c:957 #8 0x00000000004a435c in main_loop () at main.c:1705 #9 0x00000000004a8a43 in main (argc=2, argv=0x7fff58d21368) at main.c:2609 (gdb) quit kamailio -v version: kamailio 4.2.0-pre0 (x86_64/linux) a78764-dirty flags: STATS: Off, USE_TCP, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, F_MALLOC, DBG_F_MALLOC, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 4MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: a78764 -dirty Kindly let me know which version to move. -- Warm Regds.

Git commit notifications
by Daniel-Constantin Mierla 08 Dec '14

08 Dec '14

Hello, in the perspective of moving main git repository to github (where the commits will be done), with a real time mirror on kamailio.org, I am pasting here the commit email notifications that are now available, to decide on which one to use in the future -- see them at the end of the email. A) - this is what we get now from git.sip-router.org B) - this is what github sends C) - this is sent by kamailio.org when it gets the trigger (on a push to gihub) to mirror. It is done by a php script I wrote over the weekend, which does also the mirroring. The script that can be improved, I am going to push it on github these days, after a bit of polishing, so everyone can contribute to it. Right now it tries to be as close as possible to A), with: - first part of commit id in subject (github does it, thought it can be handy sometime) - links to raw diff and patch - it is missing the commit changes summary/statistics (probably can be added in the future with a bit of php coding) Given the flexibility and that it gives more details, pretty close to A), I will go to C). But if there are people simply liking B), then we can use it, being done by github, it's no overhead for us. Other opinions?

what has been the motivation that rtpengine control protocol is using udp instead of tcp or ssl? we have noticed that reply to delete containing stats is too large for a single udp packet over ethernet and causes udp fragmentation and fragmentation needed requests. -- juha

Registrar path support on lookup
by Ben Langfeld 04 Dec '14

04 Dec '14

I'm facing a problem which I believe may be a bug in the registrar module's lookup. When a registration comes with multiple Path headers, these are recorded in the location table as comma separated. When the lookup is performed and these are used to construct the Route header(s) on an INVITE, this comma-separated list is not split into multiple Route headers, but instead included verbatim in a single header. Here comes my theory for how this breaks my scenario: When the INVITE then reaches the first hop (first Path header, also Kamailio), relay() sees that the Route header is itself and/or sees that there is only one Route header. The observed result is that the first hop then sends the INVITE directly to the Contact, instead of via the second hop. An example of the situation I'm facing is shown in https://gist.github.com/benlangfeld/b374a0ce0bdb6bdc35e7. Is there a particular reason the combined path is not split on lookup? Is this a bug / oversight? Am I crazy? Thanks! Ben

Re: [SR-Users] Not getting the final response after ringing
by Rizwan Khan 04 Dec '14

04 Dec '14

I am not sure if its the issue on my client end as CSIPSImple is not sendin the PRACK that is expected by the server or the rtp ports are not opened. I guess the ports are opened as I can hear two way voice. But the following issues remain: 1. I cannot receive a call on the SIP number 2. I dont get an indication on the caller (thru CSIPSimple) that a call has started as in it doesnt start the call timer 3. The call disconnects with an error after some time ..INternal Server Error.

Kamailio Failed to Query the Asterisk DB to Authenticate Registration Requests.
by Mahmoud Ramadan Ali 04 Dec '14

04 Dec '14

Hi Dears, I'm trying to configure Kamailio as SBC in multi home mode for Asterisk by authenticating the inbound SIP registration requests,i'm following this tutorial http://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb to achieve this goal. i have modified the necessary changes like the Asterisk DB URL and the SIP table name and Username and password column and verified the Mysql connection. My topology like this Asterisk (192.168.100.10) <----Internal:192.168.100.1---->Kamailio<---External:192.168.50.1-----> SIP Phone (192.168.50.2) But when trying to register a SIP phone Kamailio generates these error messages Nov 22 17:19:20 debian /usr/local/sbin/kamailio[6434]: ERROR: db_mysql [km_dbase.c:122]: db_mysql_submit_query(): driver error on query: Unknown column 'secret' in 'field list' Nov 22 17:19:20 debian /usr/local/sbin/kamailio[6434]: ERROR: <core> [db_query.c:132]: db_do_query_internal(): error while submitting query Nov 22 17:19:20 debian /usr/local/sbin/kamailio[6434]: ERROR: auth_db [authorize.c:175]: get_ha1(): failed to query database The Auth_DB Params in the configuration file is as follows. # ----- auth_db params ----- #!ifdef WITH_AUTH modparam("auth_db", "calculate_ha1", yes) modparam("auth_db", "load_credentials", "") #!ifdef WITH_ASTERISK modparam("auth_db", "user_column", "account") modparam("auth_db", "password_column", "secret") modparam("auth_db", "db_url", DBASTURL) modparam("auth_db", "version_table", 0) #!else modparam("auth_db", "db_url", DBURL) modparam("auth_db", "password_column", "password") modparam("auth_db", "use_domain", MULTIDOMAIN) #!endif I tried also to give the Auth_DB module all the paramaters like this but still receiving the same error !

Thanks Daniel, This was exactly what I was looking for. I have also reviewed again your "Asynchronous Processing in Kamailio Configuration File" presentation from Kamailio World 2014 and it provided me an incredible amount of digested information regarding async processing(especially the part with push notification). Will follow that approach, and yes, it is a brilliant idea to pass the transaction indentifiers to CGR and process them in evapi reply route, so no more dependency on htable needed. Cheers, DanB

Refreshing the Kamailio logo
by Daniel-Constantin Mierla 04 Dec '14

04 Dec '14

Hello, I was considering to discuss the state of Kamailio project logo for a while. The current state is ambiguous, to say at least - various logos in different places. When OpenSER was renamed in Kamailio we were trying to get something new, but due to the 'forks and dark waters' at that time, this process was never completing, meanwhile using an adaptation of old openser logo. However, there are no high resolution or other variants suitable for using in particular conditions (e.g., black and white, big posters). First, a question that we should decide on: shall we aim for a new logo or try to get someone to make proper graphics from the current shape? (for reference, the logo from http://www.kamailio.org/wp-images/kamailio-rock-logo.jpg). I would prefer to go for a new logo, but I admit that this process can become complex, a mater of tastes, not something we can decide on technical aspects. Therefore, if it ends up in something that doesn't seem to have the acceptance of major contributors (with coding, advertising/promoting, ...) to the project, then we stick with current for a while. My preference is based on the fact that Kamailio evolved over the time, has its own identity, so a fresh look of the logo would reflect that better. I am listing here the options, that people can express preference on: A) New logo A1) variant based on Kamailio World logo (used by twitter kamailioproject account and on some materials at various events). It was a backup variant so far as we had high resolution graphics that could be adapted to get a good image for big posters. Can be seen at: - http://www.kamailio.org/pub/kamailio-logos/variants/kamailio-from-world-log… - http://www.fredposner.com/1471/kamailio-at-astricon-2013/ A2) use a professional service for that. Kamailio World logo was made with 99designs.com service, which is quite good considering there will be many submissions to choose between, options can be visible by everyone. There might be other similar services, this is one I have experience with and worked fine in the past -- anyhow, it has to be something that all management and solution can be done online. Asipto can sponsor at least the bronze package if 99designs is going to be used, maybe others want to participate with extra funds to get a better package. A3) leverage on community, in case some companies have internal designers or some of you have such skills or friends. Perhaps this has the highest risk on escalating, given that is going to be some direct involvement in proposals and selection. B) Old logo B1) get someone to produce high resolution graphics from existing logo No matter what variant, who will do the work or financial contribution, will get credits via our web site. However, all the rights of the resulting logo will belong to the Kamailio project. To conclude, the order of my preferences: A2, A1, A3, B1 Looking forward to feedback from many of you!

Evapi reply processing
by DanB 04 Dec '14

04 Dec '14

Hey Guys, We are in the process of implementing prepaid control using CGRateS engine and for that we will be using evapi module (thanks Daniel again for that). I was wondering if you can advice us whether the path we are taking is the correct one. On INVITE, we will initiate a MaxCallTimeout (sort of call auth) to CGRateS via evapi. Once request sent, we should "park" the request somehow (right now we are considering sleep in the process via usleep and recheck for the answer every 5-10 milliseconds). Answer should be shared via htable. Could you recommend us a better approach? On reply, the answer processed in event route evapi:message-received should set in htable a key of combination callid:fromtag with the maximum call duration or auth reject if not enough balance. This key should be processed by the sleeping process on wakeup. What do u think, is there a better way to approach the 2 ways communication? Thanks in advance for any kind of tip! DanB
