Hi,
I'd like to ask whether I am able to change an outgoing port. I'm
using t_relay for outgoing INVITEs & Kamailio uses 5060 port defined
in listen. When the call fails I am rerouting it using append_branch
and I'd like to change an outgoing port to 5061. The reason I'd like
to do this is a Loop detection of my buggy VoIP/analog gateway.
Am I able to specify an outgoing interface/port for t_relay in
Kamailio or should I find an another gateway? :)
Thanks for help
Kind regards
Efelin
Dears,
My name is suhaib mehyar,
I tried to install kamailio server, and I successfully set it up, it is

I conducted the Kamailio Development Workshop, with a great group of
participants, first results being visible as contribution to app_lua for
review on tracker.
Today is schedule to release Kamailio v3.3.4, a new minor version out of
latest stable branch 3.3. This week on Wednesday, development branch
will be unfrozen, lots of new code is already waiting to be merged there
(to be part of future version 4.1.0).
If you are in Berlin this week, participating at Call Center World
(http://www.callcenterworld.de/en/), ping me to meet, I will be glad to
catch up with what is happening on real time communications market.
Do not forget that there are open positions to work with VoIP/SIP and
Kamailio, just in case you look for new challenges in your career, check:

Dear All,
I am trying to use Kamailio 3.1.x server (called LB here) as the Load
Balancer for two other Kamailio server (called server01 and server02 here) .
Client A -----> Kamailio LB -----> Kamailio server01
Client B -----> Kamailio LB -----> Kamailio server01
If I dont use LB here , and letting Client A and B connect to Kamailio
server01 directly , all the communication is fine.
While using Kamailio LB ,without luck, although the sip client A and B
get 200 from server01 for Register,
they cannot reach each other for "Message" and "Invite".
It will be great appreciated if anyone can give a hint.
my config for Kamailio LB is as below :
==========================================
....
debug=2 # debug level (cmd line: -dddddddddd)
fork=yes
log_stderror=yes # (cmd line: -E)
children=2
check_via=no # (cmd. line: -v)
dns=off # (cmd. line: -r)
rev_dns=off # (cmd. line: -R)
port=5060
# for more info: sip_router -h

exit;
};
# if (!method=="REGISTER")

forward();
exit;
}

Hi!
I've spent five days at SIPit 30 testing Kamailio on a tiny Asus EEE-netbook. It's been great, and apart from the bug hitting me while using outbound, we've done great in all tests.
During the proxy doom test today, the netbook processed way over 50.000 messages in a single INVITE transaction that spiralled and looped and behaved in funny ways, and the CPU still had a lot of power to do other things. The hub we used was the limiting factor.
Kamailio 4.0.0 beta was involved in all multiparty tests, from TLS and RTCweb to forking, spiralling and proxy doom. We proved that we have a solid product that can handle all kind of scenarious, even TCP overflow attacks.
Thanks for all the help over jabber, IRC and other means!
Special thank you to Fred Posner who contributed a Big Fred Cookie!
Have a great weekend!

Hi All,
Given a situation where there are multiple registrars, behind a single load
balancer, sharing the same location table in DB, I understand that Path can
be used to ensure everything works nicely with clients behind NAT. So, if
UA1 is registered on P1, UA2 on P2, and UA1 calls UA2... P1 performs
lookup, sees path and sends via P2.
What about situations where the distribution between registrars is being
handled client-side through DNS SRV, not a load balancer? Path cannot be
used then, right? As I understand it, in this instance add_path() will do
nothing, is this correct?
Thanks in advance,
Charles

Hi,
Maybe some of you have encountered this funny error message when
starting and even killing kamailio on a Debian 6 with 2.6.x and 3.x
kernels and 2.11.3-4:
#-------------------------
# /usr/sbin/kamailio -f /etc/kamailio/proxy/kamailio.cfg -P

#-------------------------
The PID reported here is the kamailio attendant process. It seems to be
somehow related to the shared memory. The interesting part about that is
that kamailio really starts just fine, and there is plenty (>5GB) of
free memory available. It doesn't seem to influence the behaviour of
kamailio at all as it's working perfectly fine, so for now it's just
annoying, but I'm really curious
I've tried to fiddle with mem_join, but it doesn't matter whether it's
on or off.
Kamailio version is this:

Has anyone seen this too? What's the cause of that?

Hi All,
I am working on a kamailio proxy with a very specific goal I need to accomplish.
What I would like to do is a key-value lookup, utilizing the SDP's media contact (c= line) IP as a key, and have a function return a value for that key. It appears that I can possibly accomplish this with the AVPops module, combined with DB_TEXT (maybe DB_MYSQL in the future) and a custom table with a custom query. The only thing I seem to be missing is the ability to extract the c= IP from the SDP, and store it as some kind of variable with which to do the lookup.
I've looked into the iptrtpproxy module as it seems to have a select: @iptrtpproxy.sdp_ip that could work, but that module is extreme overkill for my purposes, and I am running into some issues getting it built for my platform (Ubuntu server 12.04). Also the documentation for that select states: "Return first rewritten IP provided at SDP c= line." However, I'm looking for the original sdp_ip, and have some concern that this won't return an IP that has not yet been re-written.
My environment has a very specific 1:1 ratio of private network, to static public IP mappings. I currently have a successful OpenSER (1.3.2) deployment within this environment (running 5 years), which uses a hacked version of the old "mangler" module, with the function sdp_mangle_ip(<network>, <ip>). I could do something similar using textops->search_body() and nathelper->fix_nated_sdp(), but the risk of a typo or syntax error in the config file every time I have to make a change or add a network is fairly high. Less importantly, there is some extra overhead as the proxy will have to test for every network on every SDP looking for a match (this is what the current deployment does). Eventually I'd like to add a simple frontend to add/edit networks on the fly, so that no one is ever touching the config.
What would you folks recommend for this? Should I look at building a custom module which only grabs the c= IP and stores it into an AVP? Am I not seeing another module that will expose that information for me already? Would it simply be easier to work on getting iptrtpproxy built, and utilizing it only for the purpose of extracting the information I need from the SDP?
Any insight would be most greatly appreciated.
Thanks,
Travis Hegner
