Rewrite BYE to Cancel
by Lars Olsson 29 Sep '20

29 Sep '20

hi, I have a Kamailio setup infront of a SIP system that do not handle cancellation of a INVITE correctly. The system sends out a BYE request instead of a Cancel request on non connected dialogs. I am trying to find a way to let Kamailio "translate" the BYE request to a Cancel reqeust for the ongoing INVITE dialog. Alternative if SEMS b2bua can do it, but currently it replies: "not sip-relaying BYE in not connected dlg", and I have not found any obvious way to rewrite it there. Any thoughts. I can not change the behavior of the remote system. Best Regards, Lars

Trying to use xavu with "two level naming"
by Chaigneau, Nicolas 29 Sep '20

29 Sep '20

Hello, I'm trying to use xavu as described in Kamailio documentation: https://www.kamailio.org/wiki/cookbooks/5.4.x/pseudovariables#xavu_id_-_xav… $xavu(a=>b) = "xyz"; # <- two level naming supported However, this does not seem to work. The second level is ignored. When calling pv_xavu_print() it only shows the last element set, e.g.: $xavu(cdru=>one) = "one" ; $xavu(cdru=>two) = "two" ; pv_xavu_print() ; Result: 11(14989) INFO: {1 1 INVITE 7rc2rGgOYS56zDqN} <core> [core/xavp.c:592]: xavx_print_list_content(): *** (l:0 - 0x7f217c55eab8) XAVU name: cdru 11(14989) INFO: {1 1 INVITE 7rc2rGgOYS56zDqN} <core> [core/xavp.c:593]: xavx_print_list_content(): XAVU id: 1863997055 11(14989) INFO: {1 1 INVITE 7rc2rGgOYS56zDqN} <core> [core/xavp.c:594]: xavx_print_list_content(): XAVU value type: 2 11(14989) INFO: {1 1 INVITE 7rc2rGgOYS56zDqN} <core> [core/xavp.c:603]: xavx_print_list_content(): XAVU value (str): two 11(14989) INFO: {1 1 INVITE 7rc2rGgOYS56zDqN} <core> [core/xavp.c:629]: xavx_print_list_content(): *** (l:0 - 0x7f217c55eab8) end 11(14989) INFO: {1 1 INVITE 7rc2rGgOYS56zDqN} <core> [core/xavp.c:632]: xavx_print_list_content(): ----- end XAVU list: 0x7f217c55eab8 (level=0) Am I missing something, or is this a bug ?

Dialog - timeout for dlg with CallID
by Ilie Soltanici 28 Sep '20

28 Sep '20

Hello, I'm trying to get CDR working in Kamailio by using the acc and dialog modules. Everything seemed to be working fine - until i noticed that for some of the calls the call duration is 0, even if that call has been successfully established and duration was for about a few minutes. In the Kamailio logs I'm getting such errors: WARNING: dialog [dlg_handlers.c:1649]: dlg_ontimeout(): timeout for dlg with CallID '304bad142b50bb3a7a117816439ea3d5' and tags 'as3adde5c7' '7d28152f-e0e3-4bcf-9d5c-21c3723b95c5' WARNING: acc [acc_cdr.c:230]: db_write_cdr(): fallback to dlg_only search because of message doesn't exist. This error I'm getting at about 2 min after the ACK message for 200 OK. I'm not sure that this is related to the dialog timeout, but below you can see the related configuration for the dialog module: modparam("dialog", "default_timeout", 10800) # 3 hours modparam("dialog", "early_timeout", 180) modparam("dialog", "noack_timeout", 90) Unfortunately, I'm not able to reproduce this issue, as that's happening randomly and just a few times per day. On the SIP Level i didn't notice any strange issues. Any ideas why is that happening? Thank you.

Lua kemi-test-suite now availble from luaRocks
by Yuriy Gorlichenko 28 Sep '20

28 Sep '20

Hello Kamailians! I'm glad to announce some updates about the Lua Kemi-test-suite which has been presented on KamailioWorld online 2020 conference https://github.com/ovoshlook/kemi-lua-test-suite There are some important updates that I hope will make your life easier if you use Lua KEMI. - Now (finally!) it is available via LuaRocks. So it is easy to go for now. No more manual source downloads! (this is the main reason I'm writing this message ). - More modules and some core functions have been mocked. It is still a lot of jobs that have to be done but the amount of available mocks is growing. - Added CRASH_PROTECTION functionality. So for now there is a mechanism which is checks if you calling a function with an incorrect amount of params ( see README ). - Extended mocking engine: now it is possible to mock any functions of KSR or third-party modules/libraries: for example, Redis, MySQL, or other connectors calls. P.S. suite still on development and changes from time to time, but published versions are stable and ready to use. P.P.S. Warm welcome to contributors.

Linphone push notifications (iOS) and kamailio
by Jan Rozhon 26 Sep '20

26 Sep '20

Hi, I know this is kind of a wrong forum for this question, but I have got no answer from linphone forum so I am trying my luck here. I have kamailio with pretty much the default config with slight modification enabling me the push notifications for iOS (via curl) and late forking (t_suspend, t_continue). But my linphone on iOS although gets awaken does not present me with the call I am trying to establish. Did anyone of you guys experimented with similar setup? If so, to what degree were you successful and can you share some insights especially on the format of push notification where I suspect my problem to be rooted? Thanks in advance and once again, sorry if I am off-topic too much. Regards, Jan
