When I look at the debian repositories maintained by the project, there are instructions to import the public key of the repository for apt using this command:
wget -O http://deb.kamailio.org/kamailiodebkey.gpg | sudo apt-key add -
which results in:
Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)).
gpg: no valid OpenPGP data found.
Is there an alternate method that can be posted in the repository that will get better results?
Thank you,
TL
Hello Kamailio list!
We have a scenario that makes use of the UAC-module to send SIP MESSAGE and
then in some cases the Kamailio process core dumps after some time after
processing messages. I have been able to gather a core dump which shows
this backtrace appended below. We are using Kamailio 5.6 retrieved from the
kamailio repository: http://deb.kamailio.org/kamailio56. We are running
Kamailio in a Docker container which runs on "5.10.0-25-cloud-amd64 #1 SMP
Debian 5.10.191-1 (2023-08-16) x86_64 GNU/Linux"
We have previously tried to use Kamailio 5.7 but it gave the same type of
crashes.
We have been using the uac module a lot but it is just in this scenario we
get a core dump. We have some kind of relation to a specific scenario but
it can take from several seconds from the last SIP message of this scenario
up to 50 minutes until the crash occurs. To me this sounds like some kind
of cleanup that is not handled properly. The back trace indicates that free
of shared memory could be the issue, but I don't know the code
unfortunately.
The last things we see in the log file is:

Hi

I assume, when kamailio is being restartet there are some expired entries still present in the database which kamailio tries to insert on a new registration.
This leads to this duplicate key error.
Is there a way to tell kamailio to use 'replace into' instread of 'insert into'?
Solution for now, is to manually delete expired entries from the database.

Hello Kamailio community,
After the January refactoring of OpenSSL integration, configurations that
initialise libssl in rank 0 (thread #1) are likely to trigger errors more
aggressively. This type of configuration has all along been broken due to
OpenSSL use of thread-local variables.
The first "victim" is https://github.com/kamailio/kamailio/issues/3727 —
the configuration has dispatcher + db_unixodbc (+ some driver) — this
configuration initialises libssl in rank 0(thread #1).
I have a couple of PRs in the queue for db_unixodbc, db_mysql (PostgreSQL
may need similar attention).
master and 5.7 branches are affected
Regards
Richard
Hello,
LCR module logic is :
When the function /load_gws()/ is called, matching gateways (that are
not currently designated as defunct) are ordered for forwarding purposes
as follows:
1.
according to longest Request-URI user part match
2.
according to tuple's priority
3.
according to tuple's randomized weight
or, if priority_ordering parameter is set to value 1, as follows:
1.
according to tuple's priority
2.
according to tuple's randomized weight
and Smaller priority value means higher priority (highest priority value
being 0 and lowest being 255). so I have 3 lcr_rule_target use the same
lcr_rule entry but 3 different Gateways and priority. So the order of
rules would be longest Request-URI (same) and the priority but the
result is:
added matched_gws[0]=[3, 5, 200, 2193562]
added matched_gws[1]=[1, 5, 2, 6888519]
added matched_gws[2]=[2, 5, 50, 2159388]
same prefix but first rule target with priority 200 and then 2 and then
50. I think the result would be priority 2,50 and 100.
¿Or not?

Hi,
I'm trying a DMQ dialog sync up setup with 2 x Kamailios. I have this scenario:
1. Kamailio1 receives INVITE and sends KDQM to Kamailio2 to sync up dialog => OK
2. Kamailio2 receives 200OK
3. Kamailio2 does not send anything back to Kamailio1 to update dialog state => not OK, i expected a KDMQ to be send back to Kamailio1 to update dialog state
I was wondering if DMQ module supports the above? I am using 5.6 version of kamailio, and I am curios if this might be implemented in later branches?
Thank you,
Stefan
Hi
https://www.kamailio.org/wiki/cookbooks/devel/pseudovariables#branch_name_-…
"Assigning $null to uri attribute will drop the branch, for the rest of
attributes will just set the value to null."
Where do I need to assing $null to the brach URI to get it dropped? And
what happens to the index, is there a gap, or do the subsequent
branches get re-indexed so they don't match with the ulc indexes anymore?
Actual example, I have multiple contacts I would like to add to branches.
Two of the contacts are from the location database + an additional
contact.
# Basic Branch:
$ru = $(ulc(aor=>addr)[0]);
$du = $(ulc(aor=>received)[0]);
$fs = $(ulc(aor=>socket)[0]);
# Additional Branch:
append_branch($(ulc(aor=>addr)[1]));
$(branch(dst_uri)[-1]) = $(ulc(aor=>received)[1]);
$(branch(send_socket)[-1]) = $(ulc(aor=>socket)[1]);
and so on, actually a loop over all ulc contacts.
# Lasst Additional Branch, point to other registrar, not to a usrloc location.
append_branch($ru);
$(branch(dst_uri)[-1]) = "sip:other-registrar:5060;transport=udp";
$fsn = "LocalUDPv4";
$(branch(send_socket)[-1]) = $fs;
t_on_branch("BR_T");
branch_route[BR_T]
{
$var(socket) = $(ulc(aor=>socket)[$T_branch_idx]);
if ($var(socket) == 0) {
xlog("L_INFO", "$cfg(route): DROPPING BRANCH: $T_branch_idx No local socket on this registrar\n");
$(branch(uri)[$T_branch_idx]) = $null;
}
}
I don't get this right! Call is still sent to that contact.

Hello,
using DEBUG with LCR module to see how the module apply the rules, I see
he use Gateway Index in the list. The Gateway Index could be different
to Gateway ID and maybe can confuse the correct interpretation about the
use of the rules.
Is it possible change the code:
matched_gws[gw_index].gw_index = t->gw_index;
matched_gws[gw_index].rule_id =
rule->rule_id;
matched_gws[gw_index].prefix_len =
pl->prefix_len;
matched_gws[gw_index].priority =
t->priority;
matched_gws[gw_index].weight =
t->weight * (kam_rand() >> 8);
matched_gws[gw_index].duplicate = 0;
LM_DBG("added matched_gws[%d]=[%u %u,
%u, %u, %u]\n", gw_index,
t->gw_index,
pl->prefix_len, t->priority,
matched_gws[gw_index].weight);
to use gateway ID and not gateway Index?
Thank you
Regards
