Hello,
several folks working with Kamailio, SIP Router, SER, OpenIMSCore, SEMS
and Asterisk are in Berlin next week, so we think of having a dinner (or
beer) meeting Thursday, 19:00, Nov 12, 2009. If happens that you are
around and want to join, please send me an email to make sure you get a
seat. As usual for this kind of event, free participation with everyone
paying for himself/herself.
Just to have an idea about how it could be, see some photos from
previous similar events:
http://www.asipto.com/gallery/v/social_meeting_barcelona2008/http://www.asipto.com/gallery/v/FOSDEM2009/
From private discussions so far, we should be already about 10 people,
confirmed including myself, Olle E. Johansson (Asterisk) and
Elena-Ramona Modroiu. There is a lot to celebrate, from integration work
within SIP Router Project to upcoming Kamailio 3.0 (now RC1).
Cheers,
Daniel

Hello everybody
I have such problem with kamailio and client which behind NAT
This is REGISTER message which came from client. This message came from
public IP (for example, 1.1.1.1) and source port 44197. (This information I
got from sip_trace)

route(11);
exit;
}

Hi,
This list becomes a mix of high-level tech and low-level beginner
questions... - and I'm in the latter group. Making two lists might be
over-kill, though.
Here's my issue:
My call termination provider is rightfully returning a 404 for a call
to a number that doesn't exist. This currently seems to spark Kamailio
to look for the next gw, but in this case there is no next gw set up
in the lcr/gw - so it returns a 503 to the caller. If I'm confident
that my provider is right that there is no such number, and 404 is the
correct answer, wouldn't it be better to return a 404 to the caller
rather than a 503? With 503 stats also get screwed up, because my
client can just see a bunch of 503s, which is not a very detailed
picture of the real situation.
If I should return a 404, how would I go about this? What would I do
in cfg to ensure that a 404 return does not spark it to look for a
next gw, but sends 404 back to the caller?
Alternatively, I could try to figure out how to get the return from my
provider saved to the acc table on the INVITE record, and I'd have
something more detailed to run stats on. Does that make sense?
Thanks!
Hi, I successfully installed Kamailio on the Amazon computing cloud (EWS),
and it runs fine. However, I can't get to it (register) from any UACs from
the public internet. In amazon, all the instances (i.e. "virtual machines)
are in a "private" IP, kindda like the private IP you get in a LAN. However,
Amazoin gives you a "public IP" that can be mapped to any machine instance
in your account, i.e. the machine that kamailio is running. However, when i
use this public IP in the configuration of the UACs, it cannot get to it.
How can I get kamailio to listen on this public IP?
Secondly, and related to the first, when I run kamailio in my LAN (behind a
router), say on 192.168.1.113, and all my UACs are in the same LAN, say
192.168.1.112, 192.168.1.114, etc, I can register ok and make calls just
fine. However, when I try to come in from the public internet, no UACs can
register to my Kamailio server (running on 192.168.1.113), even though I am
forwarding port 5060 from my router to 192.168.1.113 (where kamailio is
running). I think this problem is related to the first one, in that I cannot
get Openser (kamailio) to listen on a public IP, when it is behing a "LAN".
Can anyone help?
Lastly, the same issue with rtpproxy also behind the LAN, but it needs a
pulic IP, right? Please help...anyonw.

Greetings,
Please excuse the apparent silliness of this request, but I am curious
if there is a combination of flags passed to force_rtp_proxy()
and/or rtpproxy invocation options that can allow force_rtp_proxy() to
substitute an SDP endpoint IP that is not a physical device/interface
on the host on which rtpproxy is running?
Let me explain further:
1. I have a host with a single network interface that has private IP
192.168.1.254.
2. I am receiving an inbound call from outside the network, coming in
on a public IP address 4.4.4.4 that is a 1-to-1 DNAT/SNAT to
192.168.1.254.
3. The call is forwarded to a PBX on the same LAN as the native
interface, e.g. 192.168.1.250.
4. I would like to set up SDP in such a way that 192.168.1.250
sendsmedia to the 192.168.1.254 interface while the outside host
initiating the call sends its media to 4.4.4.4.
Under normal circumstances in which both the public and private
interface were physically present on the machine, this would call for
the use of "bridging" mode (rtpproxy invoked with -l
4.4.4.4/192.168.1.254 and use of "ie" and "ei" flags with
force_rtp_proxy() - we have previously established that
rtpproxy_offer/answer do not actually seem to work as advertised).
But is it possible to "bridge" to an IP that is not routed to the box?
I expected that force_rtp_proxy()'s second parameter - ip_address -
would do this. However, this does not appear to let me override the
SDP endpoint with any IP address I want; it seems that I am still
limited to choosing from those IPs physically available on the
rtpproxy host. I would guess that this is because ip_address is
passed as a parameter through rtpproxy's control API socket and is
validated by rtpproxy itself, and if it is not a local existing
address, is overridden with one that is.
Is there a clever combination of flags that can be used to accomplish
this, or is it a lost cause?
Thanks!
