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

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,

Dear Sir,
I am using kamailio 1.5.0, having installed and configured as given on the
kamailio site
<http://www.kamailio.org/dokuwiki/doku.php/install:kamailio-1.5.x-from-svn>
on my PC having Centos operating system. I have configured the config files
kamailio.cfg, kamctlrc accordingly as given on site.
when I start the kamailio using kamctl start command. it gives the error
message like
*[root@localhost ~]# kamctl start
database engine 'MYSQL' loaded
Control engine 'FIFO' loaded
INFO: Starting Kamailio :
ERROR: PID file /var/run/kamailio.pid does not exist -- Kamailio start
failed
*please* *help me out to solve this problem and suggest me where I am
wrong. * *I have configured kamalio so many times it gives me the same kind
of error message.

Hi,
Kamailio is running fine, but when I try run again by command line without
killing the previous, the kamailio_fifo is removed and functions fifo in
kamctl doen't work anymore. Why when I try running kamailio when already
exist one, it remove de file kamailio_fifo?
I can't find the part of source code that file kamailio_fifo is removed...
Someone knows?
Best Regards
Hello,
My setup includes a cellphone that uses Wi-Fi to hookup to the internet
with IP 192.168.1.101. Cellphone app, tries to register with VOIPSwitch
through an outbound proxy server(Kamailio + rtpproxy), which rewrites SDP
to force rtp through an rtpproxy.
I can make a call from the cellphone to a PSTN number. When the PSTN
endpoint hangs up, VOIPSwitch relays a BYE message to the proxy that looks
like :
No. Time Source Destination Protocol Info

The request URI in the above message is the IP address of VOIPSwitch
itself, which causes the proxy to forward the BYE message back to
VOIPSwitch. The cellphone never receives the BYE message and consequently
never hangs up.
Any suggestions on how i can get around this problem ?
Thanks and Regards,
Vikram.
Hello all,
I recently add a classical Audiocodes Mediant 2000 with 2x 8E1, the purpose
is to have several interconnections with PSTN.
I configured it like this :
Audiocodes registers as a gateway to the Kamailio, using a dedicated port
(5062).
Registration seems to be OK, and the pstn gw uses OPTIONS method to ping the
proxy.
I can attack the Audiocodes with a SIP phone behind Kamailio, no pbm.
But the audiocodes returns some errors about SIP headers sent by Kamailio :
( sip_stack)(44732 ) AcSIPParser: Problem in SIP Message Headers [Time:
12:30:26]
( sip_stack)(44733 ) !! [ERROR] AcSIPParser: Parse Error. Unexpected symbol
'0' in scheme. ALPHA expected
Here you have the example of an INVITE from a SIP phone to the PSTN :

The outgoing INVITE from Kamailio is exactly the same received by the
AudioCodes.
When I searched over Google, I just found 2 answers about Asterisk /
Audiocodes unsolved problem, but no more informations.
I supposed that the problem is as indicated : " s=- " where source is empty
in place of "NULL" / "0" or something like this ...
Someone can confirm or already met the problem ?
Many thanks all :)

Hi all,
For a project on which I'm currently working, I am having some problems
figuring out how to correctly configure Kamailio to communicate with RTP
Proxy in order to send media into and out of a network with private IP
address ranges.
I have a proxy set up to send the SIP traffic, and all of this is
working fine. However, I'm having some trouble getting the RTP Proxy
set up. Currently, when the call is connected, the offer/answer is made
and RTP Proxy seems to be taking over, but I'm having trouble getting my
audio to flow in both directions.
Examination of the traffic coming into and out of this machine seems to
indicate that the IP addresses aren't being mangled correctly.
Specifically, it appears the internal IP address isn't being changed to
reflect the IP address of the machine on which RTP Proxy is running, so
that when the caller tries to send audio back, the IP it's given to
reply to is 10.10.x.x, which obviously won't work.
I have tried experimenting with specifically setting IP addresses in the
rtpproxy_offer() and _answer() methods to no avail, as well as setting
various flags in those methods. However, I must admit that I'm not
entirely sure what's happening under the hood with these methods, or
what rtpproxy is doing with that information when it gets it. Rather
than continue to hack at this by trial and error, I'm hoping someone
here can point me in the right direction.
Any advice, example code or pep talks would be greatly appreciated.
Thanks in advance,

Hello,
We plan to use Kamailio as redirect server. Corresponding contact list is to
be fetched by a Lua script from DB.
The problem is about calling the required 'rewriteuri' function:
1. From lua script. both 'sr.rewriteuri()' and 'sr.modf("rewriteuri",
...)" fails to write the 'contact' field.
2. I tried an alternative way; pushing the value from lua (e.g.
sr.pv.sets("contact", "sip:...")) and got the value in the Kamailio.cfg
($var(contact)). But can't call the rewriteuri function with this variable's
value as argument. This seems to be a general problem of calling a function
from .cfg with a variable's value as parameter.
Any help much appreciated.
