Hi!
I am working successfully with Kamailio in my lab setup where Kamailio is
the SBC for Asterisk.
The network layout is looking like this:
SIP-Phone <== PUBLIC NET ==> Kamailio (SBC) <== PRIVATE NET ==> Asterisk
<== PUBLIC NET ==> Carrier
Each public network is reachable from the internet and has a local firewall
with IP whitelists.
The internal SIP transactions are UDP-only but for external phones I would
like to also listen for TCP/TLS.
For this layout to work with rtpproxy (before we move on to RTPengine), we
have to enable mhomed in Kamailio.
We also have some routing issues with packets leaving with the wrong IP via
rtpproxy (when call between carrier and external phone needs to be bridged).
Most examples show that Asterisk is deployed on the same network as the
external interface of Kamailio (-> Asterisk exposed to the public network).
In our tests, this works much better but I have great security concerns
because this Asterisk instance itself does not need to be reachable from
external.
How do other users deploy Kamailio in front of Asterisk or similar as SBC
to secure internals?
There is lot of docs for Kamailio's config but IMHO less for the setup as
DMZ (SBC) proxy.
Thank you very much.
Kind regards
Kevin
Hi!
Which hostname do I need to request for the certificate when the
servers are load-balanced using DNS-SRV?
Do I need to get the cert for the DNS-SRV subdomain (without
_sip._tls) or for the servers, eg. server0{1,2,3}.pbx.example.com ?
Thank you!
Kevin
Hi all. I'm having problems with an indialog ACK request which is not being
routed correctly.
I call loose_route and print:
$du=sip:MYIP:2443;transport=ws;r2=on;lr=on;did=1d1.7702;nat=ws
$route_uri=sip:MYIP;r2=on;lr=on;did=1d1.7702;nat=ws
But when I call
check_route_param("nat=ws") I get false result.
version: kamailio 5.1.4
any hints?
cheers,
Jon

Hello,
I'm using DMQ to sync dialogs between a active and standby kamailio
node. I noticed that when the standby takes over dialog's they do not
expire after the lifetime i set on the other node.
Is there a way to make sure that calls are terminated after the dialog
lifetime expires? I see that the timer is replicated to the other node,
but nothing happens after the dialog expires. The event routes aren't
executed as well.
Thanks,
Jan
Hello Daniel,
Just a quick update on this. After running from the 5.1 branch twice it
happened that Server became unresponsive. It never crashed and on forceful
shutdown it only generated a core with shutdown routine. Here is what the
syslog contained off while the calls were being sent to kamailio but
kamailio was not processing any calls:

Hello!
I have set of Kamailios which distributed location via dmq_usrloc.
Could I construct synthetic DMQ message from separate Kamailio node to this
cluster to get location info for the specific user?
If yes, please explain how to do it.

BR,
Denys Pozniak
I’m new to Kamailio and currently evaluating it’s capabilities. One of the things I would like to be able to do is to change outbound message transport based on some dynamic logic.
Kamailio setup: I’m running on a setup from this guide - http://kamailio.org/docs/tutorials/5.1.x/kamailio-install-guide-git/ <http://kamailio.org/docs/tutorials/5.1.x/kamailio-install-guide-git/> and using default configuration file.
In a basic scenario of one2one call, I was able to make Kamailio to forward INVITE to callee over TCP by issuing a REGISTER request with “transport=tcp” parameter. Although it worked, as far as I understand that means all communication with the callee will be happening over TCP. I would like to be able to change transport dynamically so looking for a way to do that from config file.
I tried modifying $ru/$du in the following manner, but it didn’t seem to work.
# default config content
if (is_method("INVITE")) {
setflag(FLT_ACC); # do accounting
# added to try to force TCP transport
$du = $du + ";transport=tcp";
}
Any pointers as to how can I modify the outbound message transport? Do I need to use some extra modules or can it be achieved with a basic setup?
Thanks in advance,
Ivan
Hi,
So, route[REGISTRAR_1] will, when the max_contacts is reached, reply to the endpoint with a 503 error containing a "P-Registrar-Error: Too many registered contacts" header - this seems wrong to me so I've tried to work around it with route[REGISTRAR_2] which returns the right response, but, also writes "INFO: registrar [save.c:615]: test_max_contacts(): too many contacts for AOR" to the log file, which is messy.
Does anyone have any pointers for doing this better?
Thanks,
Dan
route[REGISTRAR_1] {
if ( is_method("REGISTER") ) {
if(isflagset(FLT_NATS)) {
setbflag(FLB_NATB);
setbflag(FLB_NATSIPPING);
}
if ($avp(maximum_contacts) != $null) {
$xavp(reg=>max_contacts) = $avp(maximum_contacts);
}
save("location");
}
return;
}
route[REGISTRAR_2] {
if ( is_method("REGISTER") ) {
if(isflagset(FLT_NATS)) {
setbflag(FLB_NATB);
setbflag(FLB_NATSIPPING);
}
if ($avp(maximum_contacts) != $null) {
$xavp(reg=>max_contacts) = $avp(maximum_contacts);
}
save("location", "0x02");
switch ($retcode) {
case -1:
sl_send_reply("500", "Server Internal Error");
exit;
case -2:
sl_send_reply("403", "Forbidden");
exit;
};
sl_send_reply("200", "OK");
}
return;
}
Hello All,
I have an issue where Kamailio-RTPEngine-Asterisk calls work good when a softphone UAC on an IOS phone makes an Inbound call to a WebRTC client. However, if the softphone UAC is on Windows, it does not work (No Audio/Video). I noticed in the Wireshark trace that when using IOS I see STUN packets, but when using Windows I see no STUN packets. I believe this may be my issue, but I am not sure why the IOS would create STUN packets but when using Windows I get no STUN packets. Does anyone have any thoughts on what could be causing this?
Thank you,
Hi Jan,
Setting multi_notify parameter should fix.
Cheers,
Charles
