sanity_reply not available from sanity module
by Patrick Karton 04 May '22

04 May '22

Hello , the sanity_reply function from sanity is not available in kamailio script so i get an error when i want to use it. in the module source i see this static cmd_export_t cmds[] = { {"sanity_check", (cmd_function)w_sanity_check, 0, 0, 0, REQUEST_ROUTE|ONREPLY_ROUTE}, {"sanity_check", (cmd_function)w_sanity_check, 1, fixup_igp_null, 0, REQUEST_ROUTE|ONREPLY_ROUTE}, {"sanity_check", (cmd_function)w_sanity_check, 2, fixup_igp_igp, 0, REQUEST_ROUTE|ONREPLY_ROUTE}, {"sanity_check", (cmd_function)w_sanity_reply, 0, 0, 0, REQUEST_ROUTE|ONREPLY_ROUTE}, {"bind_sanity", (cmd_function)bind_sanity, 0, 0, 0, 0 }, {0, 0, 0, 0, 0, 0} }; why is sanity_check linked again in w_sanity_reply ? is this an error ? i want to setup specific responses for some errors and let the default ones from module work as usual. Thanks.

Hello, im using kamaliio 5.5.3 and I want to do failedover routing with DNS SRV Records. in my lab i have these SRV records ;; ANSWER SECTION: voip.oov-obs-tools-dev.svc.cluster.local. 5 IN SRV 0 33 5060 100-68-7-74.voip.oov-obs-tools-dev.svc.cluster.local. voip.oov-obs-tools-dev.svc.cluster.local. 5 IN SRV 0 33 5060 100-68-7-75.voip.oov-obs-tools-dev.svc.cluster.local. voip.oov-obs-tools-dev.svc.cluster.local. 5 IN SRV 0 33 5060 100-68-7-76.voip.oov-obs-tools-dev.svc.cluster.local. ;; ADDITIONAL SECTION: 100-68-7-76.voip.oov-obs-tools-dev.svc.cluster.local. 5 IN A 100.68.7.76 100-68-7-75.voip.oov-obs-tools-dev.svc.cluster.local. 5 IN A 100.68.7.75 100-68-7-74.voip.oov-obs-tools-dev.svc.cluster.local. 5 IN A 100.68.7.74 my config script use_dns_cache=on use_dns_failover=on dns_srv_lb=on $du = "voip.oov-obs-tools-dev.svc.cluster.local"; t_relay(); after t_relay() is called the INVITE is send to one the 3 ips corresponding to fqdn but if the first ip does not send response. the two others ips are not tried. what i want is that all the ips resolved are tried until one succeeds. is there something to do to achieve that ? do i need to interact with failure route to try next ips ?

function 'sl_send_reply' is not available
by David Villasmil 04 May '22

04 May '22

Hello guys, I'm starting to try KEMI and i already hit a snag... right now i'm simply testing with: loadmodule "app_lua.so" modparam("app_lua", "load", "/etc/kamailio/myscript.lua") cfgengine "lua" route { lua_run("send_reply"); } But i'm always getting: 0(118) ERROR: app_lua [app_lua_api.c:1633]: sr_kemi_lua_modf(): function 'sl_send_reply' is not available I'm guessing that function is not exported by the module.. if that's the case, how can i use it?

Dispatcher SRV load balancing
by Nicolas Chapleau 03 May '22

03 May '22

Just having a hard time trying to see if the Dispatcher module does LB when SRV records are used as the destination. Will the destinations be picked based on the SRV list or will it simply use the first name received? Read lots of docs, but can't seem to figure it out Thanks, Nic.

Problem with Record-Route in Public to Private Network
by Carlos Escalona 03 May '22

03 May '22

Hello! I wish everyone who reads this message a good day. I would appreciate some guidance with the configuration of my Kamailio. Initially, I have the following architecture: Endpoints <----Public IP----> Kamailio (listen PrivateIP advertise PublicIP) <----Private IP----> Asterisk CONFIG: https://gist.github.com/Carlos-Escalona94/3a289af05b05c69ae563ab29c9ec4710 In general, calls initiated from outside the system work perfectly, but I have a problem with calls initiated from Asterisk. According to what I was able to investigate and understand, the problem arises from the fact that Kamailio uses the public IP for the entire routing system that involves the Record-Route and Route Headers. This in turn causes Asterisk to get lost trying to send messages outside of the INITIAL INVITE transaction, for example, the ACK response to the 200 Ok received from the Endpoint since it tries to use Kamailio's public IP to which Asterisk doesn't have access. I tried to force Asterisk to send all messages to Kamailio's private IP regardless of their nature, but it doesn't seem like an appropriate solution. On the other hand, I tried to modify the architecture a bit so that it was something similar to this: Endpoints <---- Public IP----> Kamailio (listen PrivateIP:P1 advertise PublicIP) <---- PrivateIP-----> Kamailio (listen PrivateIP:P2) <---- PrivateIP ----> Asterisk CONFIG: https://gist.github.com/Carlos-Escalona94/4d681bb189c6190941d291965e123889 It seems to me that this would solve the problem, but I have two doubts about this architecture, the first is that I would like to know if there is an easier way to solve the problem that I am not considering, and on the other hand, I have not found a way to identify from which interface is receiving the message to perform the routing properly.
