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,
First, i have 7 years experience with Asterisk, but I started a project
with Kamailio, forgive me in advance if I say silly things...! ;-)
I set up a classic Asterisk / Kamailio configuration:
sip phones -> kamailio -> asterisk -> sip trunks/pstn.
When a call comes from the PSTN side, if I configure Asterisk as follows:
[012345678]
type = friend
username = 012345678
secret = xxxxxxx
host = dynamic
fromdomain = sip.mydomain.com
fromuser = 012345678
Standard mode:
exten => 012345678, 1, Dial(SIP/012345678) -> The call is redirected on the
phone by Kamailio ! :-)
------------------------------------------------------------------------------------------------------------------------------------------------
Trunk mode:
[mytrunk]
type = friend
username = mytrunkUser
secret = xxxxxxx
host = dynamic
fromdomain = sip.mydomain.com
fromuser = mytrunkUser
exten => 012345678, 1, Dial(SIP/mytrunk/012345678) -> The call is rejected
by Kamailio....
exten => 012345679, 1, Dial(SIP/mytrunk/012345679) -> The call is rejected
by Kamailio ....
My question is how to allow the routing of multiple numbers (trunk mode) in
a SIP account with Kamailio?
Best regards,
Mickael
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,
I'm using 'allow_trusted()' from Permissions module without a problem in a
Kamailio 4.0 routing logic. It does just work, but the MI command
'trusted_dump' tells me that the module is not in use:
'''
server:/home/jmillan# kamctl fifo trusted_dump
500 Trusted-module not in use
'''
Doing a 'trusted_reload' does neither make any query to database to
retrieve the data.
Other MI commands of same module do work correctly. ie: 'address_reload' or
'address_dump'
Note: I have tested in a Kamailio 1.5 and the result is the same.
Regards.

Hello list.
I have a question about the HTABLE module. Suppose that I have a mysql
database with 2 million of records. Is possible to load this table as a
hash table compatible with Kamailio!?
Hope someone can help me.
Thanks,

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
code:

[python_support.c:78]: #011RuntimeError: no such function
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.
