Reload an individual entry into a hash table from database
by Jonathan Hunter 05 Jul '17

05 Jul '17

Hi Guys, We are currently building a wholesale platform to route numbers to particular carriers, and we are looking to do this with hash tables. We will potentially have 100s of thousands of numbers we will need to lookup and query as to where to route them, and one idea is to populate them in a database, we would then load these values into a hash table which will be defined in the kamailio configuration file for us to query in realtime when an Invite arrives. The backend database will be modified constantly, so we would have the need to reload the hash table on demand. I can see there is the ability to reload a whole hash table, sht_reload, but is there an option to reload for an individual entry which has been added to the database, and we therefore want it in the hash table? I dont see anything in documentation (forgive me if I have missed it), is there an option to reload just an individual key entry from the database into cache? Thanks Jon

Re: [SR-Users] host to get name of local server

I haven't looked at its implementation, so be careful if it does DNS (or system call) query every time it is used, it may slow down the processing, in that case you can just store in another variable and use it instead.

host to get name of local server
by Henry Fernandes 05 Jul '17

05 Jul '17

We have multiple Kamailio 4.4.x servers and I am setting up stats tracking. I would like to track the stats for each individual Kamailio server separately like so: kamailio_1.sip.register.count kamailio_2.sip.register.count kamailio_3.sip.register.count The problem is that we use one common file (in version control) for our Kamailio configuration. Thus, I can’t just hardcode the hostname into the file because it will be the same for each server. Does anyone have a solution for me? Is there a variable that provides the hostname or is there something else I can do? Ideally, I’d love to be able to do something like this. statsd_incr($host_name + “.sip.register.count");

kamcmd dialogs count
by Arek Łazarczyk 05 Jul '17

05 Jul '17

Hi, I have a problem with kamcmd, for now i use kamctl fifo profile_get_size to get dialogs count to pass to nrpe and futher to nagios. Since fifo is deprecated, and i want to migrate to kamailio v5.0, i must change my method of counting dialogs to kamcmd dlg.profile_get_size. Problem is that i have dialog profiles values starting with 0, so kamctl fifo profile_get_size caller 004 returns correct vaule, but kamcmd dlg.profile_get_size caller 004 returns 0, i think that kamcmd converts 004 to just 4 on fly. Is there any way to prevent such behavior ? Thx4help in advance. Best regards, AŁ.

kamailio LTE HSS
by Ibrahim Almahi 04 Jul '17

04 Jul '17

Dear Expert Fellows,Good Day, I'm wonder whether kamailio developed an open source based LTE HSS handles both IMS and LTE procedures "LTE Attach, Location Update, Authentication, ....". If it's not yet developed, is there any plan for it in the near future. Thanks and have a nice day. Ibrahim Almahi966594996362

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
