I have kamailio behind a TLS termination proxy so the sockets are correctly
deduced to be TCP. However the clients only talk TLS to the proxy and are
confused when the top Via header added by Kamailio is TCP. Is there a way
for Kamailio to forcibly pretend its protocol is TLS? Like
advertised_address but "advertised_protocol" instead.
(With pjsip testing: it has a flag use_tls which ignores TCP from Kamailio
and continues to use the persistent TLS transport to proxy. Linphone fails
because it tries to honor TCP in Via and is unable to establish TCP
transport).
BTW I am using t_relay_to_tcp so Kamailio will return traffic to the proxy
as TCP even though the contact addresses specify transport=TLS.
Hi everybody,
I'm just testing Kamailio 5.4.1 with dialog replication over DMQ. This
seems to work very good. Dialogs are replicated without problems.
When I'm restarting one node I would have expected, that all dialogs are
synced again, just like in dmq_usrloc.
But this does not happen. After a restart the nodes dialog-list is empty.
Did I miss somethin? Is there a special parameter that I have to set?
BR, Björn

Hi All,
I am facing an issue in understanding how the min_se should be working in
kamailio. As per the SST documentation, it seems like if the min_se is
configured as 500, then any value of Session-Expires OR MIN-SE if lower
than 500, can be responded to by a 422.
However, I strangely see the reverse happening. To investigate further, I
looked in to the ki_sst_check_min() code in the master, and these seems
like a potential issue.
Ref Code: Inside ki_sst_check_min(), there is an if condition like below:
if (sst_min_se < MIN(minse, se.interval)) {
However, shouldn't it be the other way around? ie
if (sst_min_se > MIN(minse, se.interval)) {
because we need to send 422 if the received value(in INVITE etc) is
smaller than the sst configure min_se value?
I also found a different documentation, at
https://git.sgu.ru/oldssu/ex-opensips/blob/cb9df8d59dbb254a9d862569fd5d11f6…
where
the check is as below?
if (sst_min_se > MIN(minse, se.interval)) {
Can someone confirm if this is broken, or my understanding is incorrect?
Regards,
Harneet

Config works fine with mysql as topos backend. So the bug is restricted
to topos-redis.
Hello,
is there an rsync endpoint available or is there a possiblity of setting
this up? Creating a mirror via HTTP is a rather quick and dirty solution
and while the deb-repo can be mirrored using debmirror, the rpm repo is
hard to sync to a non-CentOS-based machine due to missing dependencies
such as yum and reposync in latest Debian-based systems.
Would be great to get some input in regards to this topic.
Cheers

Hello Henning,
Thanks for your reply. Here's what has come up after a few hours:
shm55: https://pastebin.com/h9JCePmc
shm54: https://pastebin.com/Nx5xEEnA
It seems to me htable is the culprit? Are you seeing anything different? 54
has been running for 77020 seconds, 55 for 28521 (significantly less).
I'm going to turn it off until we figure something out...
BR,
George

Hi to all,
Is it possible to set modules parameters with env values? I know that in routes we can use $env(NAME), but what about for other parameters? for example setting DB address in K8s cluster ENV values.

Hi.
I'm looking for a solution to the following problem, and wondering whether
Kamailio (with which I have very little experience so far) may be it, or
whether I'm thinking in totally the wrong direction.
The problem:
I have a SIP client application which runs on a standard Linux system, and is
extremely basic - it can REGISTER in order to receive inbound calls, and it
can send INVITEs in order to place outbound calls, and that's about it. It
handles media as well - in essence, it's a simple softphone. I can't change
it for a more capable one, before anyone suggests that :)
Specifically, this thing cannot send REINVITEs in order to put calls on hold,
nor can it handle anything to do with transfers (blind or attended).
I'm looking for something which does have these SIP capabilities which I could
put in between this application and the SIP server through which it is placing
and receiving calls, so that I can (through some sort of API) cause calls in
progress to be put on hold, resumed, blind transferred, or hold-and-attended-
transferred.
Does that sound like something Kamailio can do?
If so, can anyone point me in a helpful direction re how to go about it?
If not, can anyone suggest something else which could sit in between a very
basic SIP client and a PBX server, in order to inject these sorts of commands
into the path and thereby give me these sorts of extra call capabilities?
Thanks,
Antony.

It is possible to update value of max_while_loops dynamically in config
file?
For example, there could be a need to increase the max in some while
loop, but after the loop is done, decrease it again for other loops.
There exists an rpc command to do that, but I haven't found how to do it
in config file.
I tried
@cfg_seti.core.max_while_loops = 200;
but got syntax error.
