Rather noob question about functionality of Kamailio as an SBC
by John Millican 20 Dec '18

20 Dec '18

Hello, I have read the article at: https://likewise.am/2013/03/10/kamailio-as-an-sbc-session-border-controller/ Since this was written back in 2013, I was wondering if there has been any changes/additions/improvements in Kamailio since then that would have an impact on the conclusions made in the above article? Where I work we are in the process of 1) determining what functionality we need now and in the not too distant future 2) based on the choices made in #1, do we need a fully functional "professional" SBC or can we get away with a "pedestrian" SBC and use an application like Kamailio. Generalizations are ok of course but pointers to specifics would be awesome if possible. I know this list is not here to do my homework for me. I will be doing more research myself but I am sure there are many folks here that have gone down this road already and am hoping to benefit form their experience while I build my own knowledge. Thanks, John

Stateless non200 ACK processing
by Serge S. Yuriev 20 Dec '18

20 Dec '18

Hello, I'm trying to build pretty simple stateless proxy to stay between gw and softswitch. Most working properly but not for non200 ACKs. For some reason softswitch not accepting my ACK. Trace (note different branch in top Via for INVITE and ACK towards switch) https://pastebin.freeswitch.org/view/8f1433b0 Simplified script https://pastebin.com/u9DTSqcS I'm pretty new to this so believe doing something wrong. -- Serge S.

TOPOS with Redis Issues
by Aleksandar Sosic 20 Dec '18

20 Dec '18

Hi Guys, We're having issues trying to use redis as the db for topos. The conf is the following: ``` ... loadmodule "ndb_redis.so" loadmodule "topos.so" loadmodule "topos_redis.so" ... modparam("ndb_redis", "server", "name=srv1;addr=127.0.0.1;port=6379;db=1") modparam("topos", "storage", "redis") modparam("topos", "dialog_expire", 12600) modparam("topos_redis", "serverid", "srv1") ... ``` We've tried also with a redis server running on another machine with no success. The errors I've got in the kamailio logs are the following: ``` 2(22) ERROR: dialog [dlg_handlers.c:212]: populate_leg_info(): empty CSeq number 2(22) ERROR: dialog [dlg_handlers.c:506]: dlg_onreply(): could not add further info to the dialog ``` and ``` 17(37) ERROR: dialog [dlg_req_within.c:117]: build_dlg_t(): invalid cseq 17(37) ERROR: dialog [dlg_req_within.c:383]: send_bye(): failed to create dlg_t 17(37) ERROR: dialog [dlg_req_within.c:87]: build_dlg_t(): no contact available 17(37) ERROR: dialog [dlg_req_within.c:383]: send_bye(): failed to create dlg_t ``` Kamailio version used is this: 5.2.0+0~20181218003543.18+xenial Thanks in advance for your time, -- Aleksandar Sosic linkedin.com/in/alexsosic/ mail: alex.sosic(a)evosip.cloud

Memory allocation
by Duarte Rocha 19 Dec '18

19 Dec '18

Greetings, I have some things that i want to udnerstand about Kamailio's memory allocation. My settings are 1024Mb for shared memory and 12Mb for private memory. I'm running Kamailio on a machine with CentOS7 and 2Gb of RAM. As i understand, at startup Kamailio will allocate 1024+12*number_of_processes megabytes of memory. Is this correct? When i set up Kamailio to run with 150 processes, after starting, i still have 500Mb of free RAM and therefore not allocated to any process. That goes against what i wrote earlier. What is the best way to plan for memory specs in my machines according to the desired number of processes and shared\private memory defined? Best Regards, Duarte Rocha

RFC: updates to some core functions
by Daniel-Constantin Mierla 19 Dec '18

19 Dec '18

Hello, it was brought into discussions several times in the past about core functions not accepting variables in the parameters. I think it is time to update them during the 5.3 release development. For few of them, I added in the past some alternative function in the corex module (e.g., force_send_socket() in core and set_send_socket() in corex module). So, I see two options: 1) add a function with similar name in corex module and same behaviour like the one from core 2) remove the function export from the core and export one with the same name from the corex module First one will ensure that configs using the functions right now keep working without any update. The second one will be better in long term from the point of documentation (no duplicated docs), but there might be few cases that would require updates in the config -- iirc, there are some functions that can get special tokens in the parameters (like forward(uri:host, uri:port)), they will get an equivalent with variables, but old config will not be compatible. Obviously the reason for this email is to ask the developers and users what would be the preferred way from own point of view.

Can i try to code? Thanks.

by hamidreza ramezani 18 Dec '18

18 Dec '18

Hello everyone I have a question regarding kamailio database, I see when kamailio is stopped, usrloc -> location and imc -> imc_rooms module tables shows some information. but when kamailio is running it's not. is it possible to manually insert to these tables, I don't want to use IMC commands like #join #accept ... is it possible to access location table and see which users are registered when kamailio is running? Best regards Hamid
