dispatcher load balancing behavior..
by Jignesh Gandhi 07 May '17

07 May '17

Hello, Following is an output from my sercmd dispatcher.list command. I have noticed that sometimes the FLAGS: value is set to IX ( which is ok, it just means DEST is de-registered ) No calls are routed to this DEST, but for some reason the load balancing such as hash over callid is affected. So If I had 4 DESTs and the first DEST had FLAGS:IX, no calls would be routed to it but the next destination would get more calls than the rest. So, in the example below DEST 132.24 would get more calls than DEST 132.25 [root@ser-kam-001 ~]# sercmd dispatcher.list { SET_NO: 1 SET: { SET_ID: 1 DEST: { URI: sip:176.22.132.23:5060 FLAGS: IX PRIORITY: 0 ATTRS: reg-time=1494197124 } DEST: { URI: sip:176.22.132.24:5060 FLAGS: AX PRIORITY: 0 ATTRS: reg-time=1494197125 } DEST: { URI: sip:176.22.132.25:5060 FLAGS: AX PRIORITY: 0 ATTRS: reg-time=1494197124 } } } Thanks, --Jignesh Gandhi

Kamailio ro user
by Донат Зеничев 05 May '17

Hi. I have just written routing logic for my new sip-proxy server, but have a problem with start of kamailio. ./kamailio.cfg file has no mistakes - it's made well done. before to start coding with routing logic, of course I installed kamailio (ver 4.3.4) from repository. OS - ubuntu 16.04 and add next modules from repository: kamailio-mysql-modules:amd64 kamailio-perl-modules:amd64 kamailio-radius-modules:amd64 kamailio-tls-modules:amd64 kamailio-utils-modules:amd64 next step, I edited the ./kamctlrc file to contain proper user/password and mysql engine settings. And than, ran the kamdbctl create (without special parameters). A bit about my kamailio.cfg : fork=yes children=4 disable_tcp=no tcp_children=4 tcp_send_timeout=3 tcp_connect_timeout=5 tcp_connection_lifetime=3600 tcp_max_connections=4096 of course mpath is defined and proper modparams (depending on my ver) for modules are used. A bit about my kamctlrc: Ro and rw user are defined (and connections to needed db from these users is checked, as like it was real kamailio that tries to update some values in db - well done). Also PID_FILE and FIFOPATH are defined (/var/run/kamailio dir. created) So that, now I'm trying to start the server as a daemon, I have the following row in systemctl: ERROR: db_mysql [km_my_con.c:124]: db_mysql_new_connection(): driver error: Access denied for user 'kamailioro'@'localhost' (using password: YES) And of course all other modules can't run because they depend on the db connections. So looks like very simple problem, just need to edit mysql user table to have proper passwords. But I've refurbished ro and rw user several times, it didn't help me. Also tried to drop kamailio db with db users and run kamdbctl create again - nothing changed. I tried to find where kamailioro user can be defined as default, but didn't find any files (apart of kamctlrc in /etc/kamailio directory). /etc/default/kamailio file contains proper values and paths. Please advise something. -- -- BR, Donat Zenichev Wnet VoIP team Tel: +380(44) 5-900-808 http://wnet.ua

KEMI Python and msg.call_function()
by Samuel F. 05 May '17

05 May '17

Hi, Using KEMI Python and doing serial forking via: msg.call_function("t_load_contacts") msg.call_function("t_next_contacts") * I couldn't see that the functions are exported to KEMI yet. I'm not great with C so I haven't tried exporting them myself. I get the following in the log files: PYT {INVITE}: 5(11963) ERROR: *** cfgtrace:request_route=[] c=[] l=0 a=26 n=t_load_contacts PYT {INVITE}: 5(11963) ERROR: *** cfgtrace:request_route=[] c=[] l=0 a=26 n=t_next_contacts However, it seems to be working anyway. Is the ERROR because I use the msg.call_function() ? Is there any better way to do serial forking using KEMI? Thank you, Samuel F

Hi guys, is there any way to allow that the UAC module will make a REGISTER to another Kamailio with the parameters configured in uacreg table using the TLS protocol instead of UDP? Marino

Kamailio KEMI / Python and the usage of KSR.pv.get("$rm") vs msg.Method
by Samuel F. 04 May '17

04 May '17

Hi, I see in the examples that KSR.pv.get("$rm") is frequently used rather than the more simple msg.Method. Why is this preferred? Kind regards, Samuel F
