Kazoo module json library kamailio 4.4.1
by Grant Bagdasarian 04 Jul '17

04 Jul '17

Hi, Could someone please tell me which json library I have to install in order for the kazoo module to compile? I've tried many different json library, none of them work. It keeps complaining: make all CC (gcc) [M kazoo.so] kz_trans.o In file included from kz_trans.c:53:0: kz_json.h:12:18: fatal error: json.h: No such file or directory #include <json.h> ^ compilation terminated. ../../Makefile.rules:97: recipe for target 'kz_trans.o' failed make[1]: *** [kz_trans.o] Error 1 Makefile:511: recipe for target 'modules' failed make: *** [modules] Error 1 There is another thread regarding this same issue, but no solution was provided by the creator of the thread. Any ideas? Regards, Grant

missing request username on register
by 赵国杰 04 Jul '17

04 Jul '17

Hello all, I have two kamailio servers(A and B) with exact same config using the same mysql db. I can register to A but not B. Server B complained: ERROR: <script>: fu is sip:851968556538527744@104.198.52.31, ru is sip:104.198.52.31, rU is <null> After capture the udp packet on both server using ngrep, the REGISTER they received are both good except A returns 200 OK and B returns 403 Not relaying. I don't have a clue what went wrong. How come the $rU is null when all the headers in REGISTER are valid? Can someone please point me the direction? Thanks Jesse

contact issue on kamailio with sipml/jssip over wss
by David Villasmil 04 Jul '17

04 Jul '17

Hello guys, So i've setup kamailio 5 with wss. Registration goes ok, but when trying to call, SIPML as well as jsSIP send garbage as Contact header, something like: Contact: <sip:0ku6du26@7j65fcf53i2k.invalid ;transport=ws>;reg-id=1;+sip.instance="<urn:uuid:8b49ac42-2039-4122-9f5b-6f4e9f471f52>";expires=600 so when it passes through: if (is_method("REGISTER")) { fix_nated_register(); } else { if (!add_contact_alias()) { xlog("L_ERR", "Error aliasing contact <$ct>\n"); sl_send_reply("400", "Bad Request"); exit; } } (taken from several examples i've found around) add_contact_alias() fails because it tries to find whether the ip address in the contact header is different from the received ip, and if not, it adds the received ip as a parameter... so the call doesn't work... I assume there's a way around this, can anyone help? Regards, David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337 ᐧ

Using lock() correctly
by Sebastian Damm 03 Jul '17

03 Jul '17

Hi, for a project I need to make sure, I have a setup where I get mirror-traffic into Kamailio which has to do something with it. To work correctly, I need to make sure, the initial INVITE is processed correctly before any reply to the same call. So I thought I use lock() and unlock() for it. This is what the relevant kamailio.cfg part looks like: request_route { xlog("L_INFO", "Got new packet $rm: $si => $Ri\n"); route(li); } onreply_route { xlog("L_INFO", "Got new packet $rm: $si => $Ri - Reply Code $rs\n"); route(li); } route[magic] { lock("$ci"); xlog("L_INFO", "Obtained lock, calling lua...\n"); if(!lua_run("handle_packet")) { xlog("L_ERR", "SCRIPT: failed to execute lua function!\n"); } unlock("$ci"); xlog("L_INFO", "Lua finished, released lock...\n"); drop; exit; } And this is what the log says: Jun 28 13:27:04 busch /usr/sbin/kamailio[18836]: INFO: <script>: Got new packet INVITE: 172.20.21.247 => 172.20.21.4 Jun 28 13:27:04 busch /usr/sbin/kamailio[18836]: INFO: <script>: Obtained lock, calling lua... Jun 28 13:27:04 busch /usr/sbin/kamailio[18836]: INFO: app_lua [app_lua_sr.c:98]: lua_sr_log(): some logging Jun 28 13:27:04 busch /usr/sbin/kamailio[18837]: INFO: <script>: Got new packet INVITE: 172.20.21.4 => 172.20.21.247 - Reply Code 407 Jun 28 13:27:04 busch /usr/sbin/kamailio[18837]: INFO: <script>: Obtained lock, calling lua... Jun 28 13:27:04 busch /usr/sbin/kamailio[18837]: INFO: <script>: Lua finished, released lock... Jun 28 13:27:04 busch /usr/sbin/kamailio[18836]: INFO: app_lua [app_lua_sr.c:98]: lua_sr_log(): some more logging As far as I understand the documentation, the second packet should wait for the lock on the Call-ID before executing the lua function. So process 18836 should finish its lua execution before 18837 can do anything further. Did I completely misunderstand the lock() function? I'm using Kamailio 5.0.2. Thanks for helping me understand what Kamailio is doing here. Best Regards, Sebastian

drouting / do_routing / prefix unknown
by Jean Cérien 03 Jul '17

03 Jul '17

Hello I am using Kamailio 5.0.2, with module drouting to do prefix based routing. 1. When I call do_routing and the prefix is not known, the r-uri remains unchanged. Is there a way to detect that the prefix is unknown, other than r-uri remains unchanged ? 2. I have the following parameters modparam("drouting", "db_url",DBURL) modparam("drouting", "sort_order", 0) modparam("drouting", "use_domain", 0) modparam("drouting", "force_dns", 1) # modparam("drouting", "enable_keepalive", 1) If I enable keep alive, I get the following error: Jun 20 22:37:17 kamailio1 kamailio: ERROR: <core> [core/modparam.c:141]: set_mod_param_regex(): parameter <enable_keepalive> of type <2> not found in module <drouting> yet, the documentation leads me to think that it should work: *NOTE: this option is only compatible with <em>sort_order</em> 0 currently. With sort_order value of 1 or 2, destinations status will simply be ignored.* Thanks for your help J.

03 Jul '17

Hello, In my Platform i have a kamailio used as pseudo SBC and a kamailio used as Proxy (AS trigger) (cpl are applied on this instance). When I make a call and callee doesn't answer that call my SBC detects the timeout and generates a 408 to Proxy (according to fr_inv_timer) , but it generates CANCEL too. Is it possible to deactivate these CANCEL? if not what is the configuration in order to be able to trigger CFNA? Regards, Frédéric

evapi module and async_relay
by Diego Nadares 03 Jul '17

03 Jul '17

Hi guys, Anybody knows if evapi sends messages to the clients immediately when async_relay is called? The normal behavior is 1 or 2 netstrings per message but I see that sometimes it starts to enqueue and starts sending for example 4, 5, 15, 30, 52.....327, 645 per message. Cheers, Diego
