Dear sr-users,
I am trying to set up a simple Kamailio server with rtpproxy on the same
host computer, behind a NAT router. “Run your own Skype-like service” is
my set-up guide, but I’m using Kamailio version 5.1 so I modified the
config files that came with the download. My problem is that SIP clients
can register over the internet via TLS encryption with the server and
establish a call session connection, but the ZRTP media connection is
not being made. Once the call session connection is made, both clients
send out UDP packets to each other, but neither receives them—the media
traffic is one way and being dropped somewhere.
I’ve tried different rtpproxy start settings. If I start the rtpproxy
service with “sudo /etc/init.d/rtpproxy start” then it uses the default
“unix:/var/run/rtpproxy/rtpproxy.sock”. I’ve also tried starting with
“sudo rtpproxy –l /my_public_ip/ –s udp:localhost:7722” which then asks
for either –F (superuser) or –u (user). I’ve tried it both with options
“–F” and “-u kamailio kamailio”. All the variations tried so far have
the same result as noted above.
The server behind the router is in a DMZ zone that bypasses the router
firewall.
Is there anything in the user-list archives that addresses this issue?
Or some likely place to start troubleshooting the problem?
Any suggestions would be greatly appreciated. Thanks in advance.
Steve

Hello Dears,
can you please tell me what are the differences between the github version
of ims modules and the ng-voice modules introduced by Mr Carsten repo ?
Thanks in advance
Hello,
in the past 10 years or so, many of us met at Fosdem conference in
Brussels (the edition this year happens during February 3-4) and had a
dinner on Saturday evening. I know already couple of people from
community that will go there, so the question is if there is any
interest to organize again such event.
If yes, it will be again on Saturday, on the evening of the 3rd of February.
At the past editions, it turned into an all-RTC dinner, but we can
consider to have it alone again (eventually with few other invited
friends), if there are too many or people want a smaller meeting.
Reply this week if you want to join, so we can estimate how many seats
we need and have enough time to find a place that can accommodate us.
More about Fosdem can be found at:
- https://fosdem.org
There is a devroom on Sunday with topics covering real time
communications. I will have a presentation there.
Cheers,
Daniel

Our topology is:
Client <> Client Router <> Internet <> Firewall (NAT) <> Kamailio <> FS
Unfortunately, when enabling SDP Rewrite: fix_nated_sdp, 0x08, it rewrites packets to the firewall external IP, not the client router external IP.
Right now we have to do a local NATed IP on each phone.
Hi,
Which module would be best suited for routing calls based on A and B numbers?
We're currently using the LCR module, with some additional htables to add this functionality, but I was wondering if there is a module which does exactly this? Or perhaps a combination of modules?

Hello!
Yesterday I read email conversation "Distributed Presence between Multiple
Kamailios" where it was suggested to use Presence module with new dmq
parameter. So was wondering if someone was thinking about approach to share
registrations between multiple Kamailio servers without using database?
Thanks!
Greetings,
My proxy does some number normalization in order to guarantee E164
numeration. It also verifies for valid Calling Numbers and replaces them if
needed.
In order to this, i'm updating the $fU pseudo-variable. Should i update the
"Contact" Header too? I've made some testing and i can get calls to work
with keeping the Contact intact and changing it to the new number. What is
the most correct approach?

Hi,
I'm working on multiple Kamailios that have users distributed evenly among
them, I now need to enable presence in those Kamailio boxes. The scenario
is a mesh where any user may have subscribed to BLF of other user
registered & calling on any other proxy.
What modules can help me achieve this? can this be done without creating a
new Presence-Node for the whole environment?
Hope to get some suggestions on how experts here have done this.
Looking forward to positive response.
Regards,
Sammy
Hi,
I have an htable containing some black list words (i.e. user IDs or phone
models). To find matches of the words in every message I use the following
script:
sht_iterator_start("i1", "black_list");
while(sht_iterator_next("i1")) {
if ( search($shtitval(i1)) ) {
// do something
}
}
sht_iterator_end("i1");
How can I modify search($shtitval(i1)) to get case insensitive matching?
The example below does not work:
sht_iterator_start("i1", "black_list");
while(sht_iterator_next("i1")) {
$var(re) = $shtitval(i1) + "/i";
if ( search($var(re)) ) {
// do something
}
}
sht_iterator_end("i1");
Other possible modifications of $var(re) aren't working too.
Thanks,
Andrey
