other proxy. The first proxy should do that.
Post by Bruno EmerHello Guys!
Good news about my tests here!
I found some configurations relative to Outbound proxy and I get this
working. Now, I can have two outbound proxies, one registrar and one
database. I can register one user in the Outbound Proxy1 and one user
in Outbound Proxy 2 and place a call between these users.
But now I'm facing another problem! The ACK messages are not being
delivered, so the session is being dropped after a few seconds. I
think that the problem is in the Contact field. Trying to investigate
it now!
I'm not sure about how to change the message to deliver the ACK. Did
someone had this problem before?
In anycase, here is the routing configuration that I'm using in my
request_route {
if (($Rp == MY_WS_PORT || $Rp == MY_WSS_PORT)
&& !(proto == WS || proto == WSS)) {
xlog("L_WARN", "SIP request received on $Rp\n");
sl_send_reply("403", "Forbidden");
exit;
}

exit;

$du = "sip:REGISTRAR_IP:REGISTRAR_PORT";

Hi, Daniel and Frank!
Thanks for your support!
Now, I changed my scenario just a lil bit to make it easy to
1. Created a server using the "Outbound" module configuration
example, but add WebSocket support in it. (IP Address 192.168.1.16)
2. Created a server running as Proxy and Registrar with
WebSockets support. (IP Address 192.168.1.15)
Register requests to the Oubount server (192.168.1.16).
4. I'm also using an external postgres database to store the
user informations. In my proxy/registrar server, I've configurated
"modparam("usrloc", "db_mode", 3)", so it will not store data in
memory.
After register the users in my scenario, I can see the following
id | ruid | username | domain |
contact | received | path | expires
| q | callid | cseq | last_modified |
flags | cflags | user_agent | socket | methods |
instance | reg_id

So, I can assume that both users are registered and ready to start
sessions.
Now, when I try to start a new session between then (let's say bob
SIP/2.0 500 I'm terribly sorry, server error occurred (1/SL)

What I understood about this problem is that the Proxy server is
trying to forward the INVITE to the Outbound server and this
server does not know that to do with this message - like forward
it to alice.
I'm stucked in this step.

Ok, Daniel!
I am trying exactly what you said, but for some reason the
proxy server can't forward the message back to the WebSocket
server. I am getting "487 Unresolvable destination". Appears
that my Proxy Server can't get data from usrloc.
When I register an user using WebRTC I can see that the system
stores the information in kamailio database and in the field
"contact" it puts a string. The Proxy server is looking in
database and just find this information. Actually, I'm trying
to understand the entire process that envolves passing
information from an Edge Server to a Proxy server that sends
the Register information to another Registrar server (as I
described before). The database is shared between all the
servers, and they are in the same network.
I just read the information in another topic, as you said, but
I think that my case is a lil bit different from it. I you
agree, I can post my configuration files here. Maybe this can
help another users with the same problem!
Thanks again!!!

Hello!
I am relatively new to Kamailio and I'm trying to create a
new enviroment using it in my company. I am thinking about
use Amazon to host the servers and use OpsWorks to
automatically escalate then if necessary. To accomplish
this, my idea is to separate the servers, using one
dedicated server to run as WebSocket, one to run as proxy
and one as a Registrar. I'll be using just one database to
store informations to all of my servers. With this, if I
need more resources later, I can just create new servers
with the specific roles (WebSockets, Proxy, Registrar).
By now, the idea is clear, but the point is that I don't
know how to separate the WebSockets server from the proxy
server. Actually, I can do this, but when I have one agent
using a regular softphone and one agent using WebSockets
(with JSSIP) they are not able to establish a session if
the softphone user starts it. Now, I want to know if is
there a way to use two websockets servers, register users
using both of then and start sessions between then, with a
separated proxy and registrar.
Has anyone done this before? Is possible to use kamailio
like this?
Thanks.
