Hello, Kamailio SIP Server v4.3.2 stable release is out. This is a maintenance release of the latest stable branch, 4.3, that includes fixes since release of v4.3.1. There is no change to database schema or configuration language structure that you have to do on previous installations of v4.3.x. Deployments running previous v4.x.x versions are strongly recommended to be upgraded to v4.3.2. For more details about version 4.3.2 (including links and guidelines to download the tarball or from GIT repository), visit: * http://www.kamailio.org/w/2015/09/kamailio-v4-3-2-released/ RPM, Debian/Ubuntu packages will be available soon as well.

Problem with registering softphones
by rasx0＠Safe-mail.net 10 Sep '15

10 Sep '15

Hello! New user here. I'm testing Kamailio installation in testing environment. SIP domain is reachable, Kamailio itself is working fine yet I have a problem with registering softphones. I've tried 3 sip apps and with only one I am able to register with server. Server itself is "vanilla", no changes made. There is user, domain, pwd defined and nothing else. App that successfully connects is X-Lite, after unchecking "Register with domain and receive calls" and checking "Set outbound as domain". Other apps are: Zoiper, Jitsi. After many "checks" and "unchecks" of literary every option I still can't get them to work with me. I'm looking for any kind of hints as of how to get it to register as well as where may I find kamailio logs?

No SDP offer answer -> therefore we can not do Rx AAR 1(875) ERROR
by Jan Devai 10 Sep '15

Hi Guys, can anybody help us find why we do not get SDP offer answer, see error below: dev_pcscf: 3(879) DEBUG: ims_qos [mod.c:643]: w_rx_aar(): No SDP offer answer -> therefore we can not do Rx AAR 1(875) ERROR: <script>: ACK ( sip:+4620950160102@ims.mnc004.mcc232.3gppnetwork.org <sip:+421950160102@ims.mnc003.mcc231.3gppnetwork.org> (10.50.21.133:5080) to sip:+4620950160101@ims.mnc004.mcc232.3gppnetwork.org;user=phone <sip:+421950160101@ims.mnc003.mcc231.3gppnetwork.org;user=phone>, 3FD60673-55F09407000575C3-18269700) Since we do not get the information the SubscriptionID should be imsi(a)mncxx.mccxx.3gppnetwork.org in our AAR and instead it is contructed as imsi@ip:port which creates a REJECTION in AAA. Any help about where to correct this fault, or where exactly in the code this reception happens and/or anything will be appreciated BIG TIME :-) Thank you Jan

Dialog module issue
by Yuriy Gorlichenko 09 Sep '15

09 Sep '15

Hello. I try to manage by dialog module every signaling session, that goes through my proxy. I added newx mod params modparam("dialog", "timeout_avp", "$avp(i:10)") modparam("dialog", "dlg_flag", 4) modparam("dialog", "initial_cbs_inscript", 1) modparam("dialog", "profiles_with_value", "caller") modparam("dialog", "track_cseq_updates", 1) modparam("dialog", "ka_timer", 10) modparam("dialog", "ka_interval", 30 And at request route I added this for all invite methods if (is_method("INVITE")){ $dlg_ctx(timeout_route) = "DIALOG_END"; $avp(i:10)=43200; $dlg_ctx(timeout_bye) = 1; dlg_set_property("ka-src"); dlg_set_property("ka-dst"); dlg_manage(); xlog("L_INFO","Dialog manage is {$ct}\n"); ... } So after this As I think every session must be dialog managed session and every leg of call must be checked by keepalive OPTIONS packets but no one OPTIONS request generated wen session goes through my proxy. thanks

Using PSTN as "fallback"
by Michael Nielsen 09 Sep '15

09 Sep '15

I have Kamailio running and connected to a PSTN gateway. My subscribers are named ex. +442071234567 - same as their real GSM number from my PSTN gateway. I'm using the standard kamailio.cfg which ships with version 4.3. When I'm trying to dial SIP client to SIP client I would like to have Kamailio route the call internally if a subscriber exists with ex. +442071234567. If no subscriber exists with ex. +442071234567 it should send it to my PSTN gateway. As it is now it seems as if it are trying to both call "internally" and via the PSTN gateway. How should one fix this issue the best way?

Hi, I'm randomly getting crash in my Kamailio with an error in log files like this: <core> [pass_fd.c:293]: receive_fd(): ERROR: receive_fd: EOF on 19 ALERT: <core> [main.c:775]: handle_sigs(): child process 6853 exited by a signal 11 ALERT: <core> [main.c:778]: handle_sigs(): core was generated INFO: <core> [main.c:790]: handle_sigs(): INFO: terminating due to SIGCHLD *Version of Kamailio is:* [root@kamailio /]#kamailio -V version: kamailio 4.1.4 (x86_64/linux) 39adca flags: STATS: Off, USE_TCP, USE_TLS, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, DBG_QM_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: 39adca compiled on 03:48:50 Aug 1 2014 with gcc 4.4.7 And gdb bt output is attached in text file.

Thanks, Sammy

Best practise for limiting concurrent calls across a cluster
by jay binks 08 Sep '15

08 Sep '15

Hey all, So I have a cluster of Kamailio servers ( 4 servers currently, soon to be 8 ), I'm looking for suggestions about the BEST way to achieve concurrent call limiting on a per customer basis, across the whole cluster. Initially I mis-read the dialog module documentation and assumed that dialog would provide me this ability, when used with a database. however it seems that the dialog module does not pull data from the DB after the initial startup. I know I can use sql ops to increment and decrement using event_route[dialog:start] and event_route[dialog:end]. however the database I've chosen ( for other valid reasons ) does not have an atomic increment and decrement. I could add yet another DB, but that just adds more failure points. so lets forget my setup, Im wanting suggestions about the BEST setup for this sort of thing. while remaining fault tolerant, and preferably without relying on any single point of failure. Sincerely Jay
