Hello,
I'm currently experiencing some odd behaviours when using these functions
and I need some help debugging to find the root of the issue.
I receive a call from a client and do some changes to the To and From
header using auto mode with password. Encrypted info goes on the
Record-Route header parameters (vsf\vst) normally.
1 - On subsequent requests sent by the originating client, domains on To
and From header are different from the ones sent in the first INVITE. In
this scenario, somehow the automatic modifying has errors on the end
result. Can the different domains affect the end result of the automatic
modifying or only the vsf\vst parameters and password are needed to the
auto replace\restore?
2 - How can I decrypt the info on vsf and vst parameters in order to verify
the info sent and the encryption?
Cheers,
Duarte Rocha
Hello,
I have some questions regarding uac_replace methods.
When I receive the first INVITE from someone I change To and From using
uac_replace_to() and uac_replace_from(). I do this only on first INVITES.
In order to restore them I use the "auto" so the changes are restored
automatically in replies or requests sent to the call originator..
In the case of subsequent requests from the originator kamailio still
changes To and From without me using uac_replace functions. Is this caused
by the auto restore? Does it work for both sides and is this is the
intended behaviour?
Cheers
Hello,
Im having a hard time figuring out how to handle a 302 reidrect, the uac_redirect modules shows a simple configuration. However for me, what it is not doing is changing the 302 back to invite. It is sending the 302 as is on.
if(!t_check_status("3[0-9][0-9]")) {
exit;
}
get_redirects("3:1");
t_relay();
This code just relays the 302 for me. I should add I am using this with the DISPATCHER module so perhaps that has something to do with my issue.
Setup is this, kamailio is sitting between to sip servers, so the flow goes like this, sip_server_a -> kamailio -> sip_server_b. sip_server_b only responds with 302 redirects, sip_server_a does not handle 302’s at all. Kamailio will only get invites from sip_server_a, and the redirects from sip_server_b will only have one contact. How can I get kamailio to reply to sip_server_a’s invite with the updated INVITE?
My config is a mesh of the dispatcher example and uac_redirect example with this specific section handling the redirect:
# Sample failure route
failure_route[RTF_DISPATCH] {
xlog("L_NOTICE", "RTF_DISPATCH: ");
if (t_is_canceled()) {
exit;
}
# next DST - only for 500 or local timeout
if (t_check_status("500")
or (t_branch_timeout() and !t_branch_replied()))
{
if(ds_next_dst())
{
t_on_failure("RTF_DISPATCH");
route(RELAY);
exit;
}
}
if (t_check_status("302")) {
xlog("L_NOTICE", "RTF_DISPATCH: 302 ");
if (!get_redirects("1:1")) {
xlog("L_NOTICE", "RTF_DISPATCH: failed to get_redirects ");
t_reply("480", "Temporarily Unavailable");
exit;
}
xlog("L_NOTICE", "RTF_DISPATCH: got redirects ");
t_relay(“sip_server_a”,”5060”);
}
}
Any ideas what I am doing wrong is this supported? Im expecting once I relay this message that it should be an INVITE not a 302 redirect. I cant find any examples of anyone else really doing this.
hello ,
i have installed kamailio 5.7 from debian repo http://deb.kamailio.org/kamailio57 bullseye main
but i dont find the posops module in the directory modules.
what is the exactly package where i can find it.
Thanks.
Hello,
I have the following statement:
if KSR.is_method("INVITE") then
KSR.log("info", "method not allowed " .. KSR.kx.get_method() .."\n");
KSR.x.exit();
end
For some reason, it falls into this condition no matter which method I use, I tried OPTIONS, NOTIFY etc.
log file: <core> [core/kemi.c:152]: sr_kemi_core_log(): method not allowed OPTIONS
the same with this check:
if KSR.is_method_in("I") then
KSR.log("info", "method not allowed " .. KSR.kx.get_method() .."\n");
KSR.x.exit();
end
this is the lua modparam settings:
# ---- lua params ----
modparam("app_lua", "load", "/usr/local/etc/kamailio/main.lua")
modparam("app_lua", "reload", 1)
modparam("app_lua", "log_mode", 1)
cfgengine "lua"
version: kamailio 5.7.0 (x86_64/linux) 1c23c2
Any idea what I'm doing wrong?
Hi members,
I am setting up kamailio as loadbalcer for asterisk server farm with
active-backup conf in Azure cloud using azure loadbalcer, for incoming it
works fine external incoming traffic with nated external IP,
can any one guide how to do active-backup configuration for internal
traffic, as asterisk servers are running on local network.
Thanks and regards

Hello,
I’m in a scenario where i would apply different modification to $tU to User with KEMI, but I can’t achieve it.
I managed to reproduce it with legacy config :
Scenario 1 (both values concatenates):
route[dbg] {
$tU ="aaa";
$tU ="bbb";
}
To: sip:aaabbb@5.5.5.5
Scenario 1 (both values concatenates and @ disapears):
route[dbg] {
$tU ="aaa";
$tU=$null;
$tU ="bbb";
}
To: sip:aaabbb5.5.5.5 --->without @
I tried different combination with [*] as for avps without success, does anyone have an idea about how to perform it ?
Regards,
David
Hi List
Does someone know a function to test a number against the carrierroute
module, to see which route it picked?
My Idea: We have multiple Kamailio-Proxies and I would like to test a
number against all hosts to see where it will be routed, without
performing testcalls.
Regards
Stefan
