Hi,
I have two SIP servers, *A* and *B*, connected each other though a OPENVPN
tunnel. The server *B* needs to t_relay() every SIP message containing the
method MESSAGE to the server *A* but these messages never reach destination.
I have tested the tunnel connectivity and works fine. I wrote a Perl script
(located in *B*) that sends SIP MESSAGES to Kamailio (located in *A*) trying
to figure out what is happening but these messages are received by *A* and
processed correctly but when *B* does the same from Kamailio, it is never
received.
Here is the route part of kamailio.cfg in *B*:
Observation: ($rU == "1004") result is *true*
*
if(is_method("MESSAGE"))
{
if($rU == "1004")
{
xlog("L_INFO","En 1004");
rewritehost("10.8.0.1");
if (!t_relay())
xlog("L_INFO","MIO Error en t_relay");
t_reply("200", "Ok");
xlog("L_INFO","MIO despues rewrite");
exit;
}
.....*
The perl script that WORKS:
*$msg = 'MESSAGE sip:1004@192.168.1.2:5060 SIP/2.0
Via: SIP/2.0/UDP 192.168.1.2

Hi, I have Kamailio as SIP server and RTP server. Client is PJSIP.
I read that STUN is for non-symmetric NAT, and RTP server is for symmetric
NAT.
Supposed A calls B.
If A, B both use symmetric NAT and STUN, they cannot hear each other
If A or B use non-symmetric NAT and NOT using STUN, they cannot hear each
other.
Why is that?
I read http://tools.ietf.org/id/draft-takeda-symmetric-nat-traversal-00.txt
for Prediction Failure, is that related to this problem ?

Hi All,
I have build Kamailio 4.0.1 from source in CentOS 5.8(i386
architecture).I followed all instructions from
http://www.kamailio.org/wiki/install/4.0.x/git.(Though Modules_k directory
is not generated).I then edit kamailio.config file for websocket support as
described in webocket.cfg file in exmples directory.But while starting
kamailio it gives following error
ERROR: load_module: could not open module : libunistring.so.0: cannot
open shared object file: No such file or directory
0(30270) : [cfg.y:3567]: parse error in config file
/usr/local/etc/kamailio/kamailio.cfg, line 318, column 12-57: failed to
load module
I checked websocket.so file in the specified directory and it is
already there.Can you please help me what's wrong with it?
please help.

Hello all,
Just wondering if anyone know any tutorial on setting up HA+DRBD solution for kamailio.
Especially creating partitions, DRBD devices and mount points.
Thanks in advance,

Hi,
is there any way to return values from a call to python_exec function
orther than the default returned integer?
Following code generates this error:
Oct 1 09:08:23 zskio /usr/sbin/kamailio[21789]: ERROR: app_python
[python_support.c:38]: python_exec2: Unhandled exception in the Python

if (!python_exec("get_provider",
$(var(clean_uri){s.prefixes}))) {
xlog("L_ERR","Can not choose a provider for $rU\n");
sl_send_reply("503","Can not choose a provider
for $rU");
exit;
}
def get_provider(self, msg, param):
# snipped code...
result = self.util.get_provider(prefixes, position, mode)
if result is not None:
LM_ERR("mode: %s position: %d result: %s" % (mode,
position, result))
# this raises error
msg.call_function('rewritehost', result['provider']['ip'])
return 1
return -1
I tried to use headers as transport but this simple code does not work:
Oct 1 09:45:31 zskio /usr/sbin/kamailio[22303]: ERROR: <script>: No header
if (!is_present_hf("X-Test-header")) {
xlog("L_ERROR", "No header\n");
}
else {
xlog("L_INFO", "Header added\n");
}
def test_set_header(self, msg):
msg.call_function('append_hf', 'X-Test-header: test\r\n')
return 1
Thanks in advance.
Hi
I am using Kamailio 4.0.1 in front of an asterisk servers farm to handle TLS with our clients and providers. The idea is to have kamailio "talking" SIP/UDP/5060 and TLS/TCP/5061 with the customers and providers and regular SIP/UDP/5060 with our internal asterisk servers.
So far at least for the customers it looks like it can work. But I have a problem, when the call is established and the called person hangs up, the BYE from the called person to the calling person is ignored. Only when the calling person hangs up first the call is terminated properly.
This is what I have been able to see:
1- Customer starts the TLS handshake/connection.
2- Kamailio authenticate it, then routes the call to the asterisk server using regular SIP/UDP/5060 but I see that it is inserting 2 Record Routes in the INVITE:
Record-Route: <sip:192.168.1.58;r2=on;lr=on>
Record-Route: <sip:192.168.1.58:5061;transport=tls;r2=on;lr=on>
3- The Contact on that INVITE to the asterisk also comes like this:
Contact: <sip:94167032@172.31.196.21:53325;transport=tls>
4- The ACK sent to the asterisk once it accepts the call (200 OK) also has those 2 Record-Routes:
Record-Route: <sip:192.168.1.58;r2=on;lr=on>
Record-Route: <sip:192.168.1.58:5061;transport=tls;r2=on;lr=on>
5- The call is established, once the called person decides to hang up the BYE looks like this:
BYE sip:94167032@172.31.196.21:53325;transport=tls SIP/2.0
Via: SIP/2.0/UDP 192.168.1.59:5060;branch=z9hG4bK40fa1c23;rport

My kamailio TLS config is shown below:
enable_tls=yes
loadmodule "tls.so"
# ----- tls params -----
modparam("tls", "config", "/usr/local/kamailio-4.1//etc/kamailio/tls.cfg")
modparam("tls", "private_key", "./privkey.pem")
modparam("tls", "certificate", "./kamailio1_cert.pem")
modparam("tls", "ca_list", "./calist.pem")
modparam("tls", "verify_certificate", 1)
modparam("tls", "require_certificate", 1)
The TLS client that I am using is called Blink.At this point I don't know whether kamailio is sending the BYE using TLS to the customer and waiting for the 200 OK from the customer or whether kamailio does not like something in the BYE and that is why is ignoring it.
I see some encrypted packets from kamailio to the client but I don't know what is inside.
Any help would be very appreciated.
thank you

I tried to call record_route_preset() in branch route in order to add
contact specific RR headers when request is forked to more than one
contact. What happened was that I got error message:
Sep 26 17:03:47 wheezy2 /usr/sbin/sip-proxy[2436]: ERROR: rr [rr_mod.c:256]: Duble attempt to record-route
Is it really so that record routing is not a branch specific thing? Is
there a way to solve this problem?

Hi,
I want to implement the call control by
1. Validating the CLI and get the credit from DB
2. Check the Rate for the dialed number
3. set the call timeout for the call duration. ( credit/rate)
4. pass the call to remote PSTN GW
Please guide me on this.
Regards,
Roy.
Dear List,

Could anyone help here ?
I think it is only some configuration problem, but i'm not sure how to
solve it.
