Hi, sorry forgot to cc before.
I have more questions regarding my load balancing setup.
1. Since the dial plan is configured exactly on Asterisk (at
etc/asterisk/sip.conf and /etc/asterisk/extension.conf), do we need to
enable MySQL for Kamailio installation?
If you store the load balancing list in
database, then you need the
database storage. Alternative is to use plain text file.
Or the default installation configuration will do
(without additional
dialplan or MySQL setting)? My idea is only using Kamailio as pure
load balancer so we hope to do this as simple as possible without
degrading the function.
2. I assume using Kamailio dispatcher module will forward some of the
users to asterik server 1 and some of them to asterisk server 2. Then
if user A is registered with Asterisk server 1 and user B is
registered with Asterisk server 2, can user A call user B? Without
Kamailio, the answer is no since they are in different Asterisk
server. With Kamailio, I am expecting both user A and B can call each
other although they are registered with different servers. Is my
configuration enough to achieve this function? Or do we need some
additional setup for this?
You can achieve this with proper routing logic in the
config. You need
to have a rule for partitioning the users and then you know where each
user is registered and direct the calls for him to the right asterisk.

Thanks again.

Hi,
I searched around the web to load balance asterisk servers and
found Kamailio for possible solution. Let's say I have two
identical asterisk servers with same dialplan and
configuration and I want both servers look like they have same
IP address from clients. Based on my understanding, we need 1
Kamailio as load balancer and 2 Asterisk servers as the real
servers. Let's say the setup is :
Kamailio load balancer 192.168.2.1
Asterisk Server #1 192.168.2.2
Asterisk Server #2 192.168.2.3
My question is, X-Lite softphone Configuration should be set
to domain 192.168.2.1, right?
I also want to know the step by step configuration to set
kamailio as load balancer. I have not used Kamailio before.
However after searching the documentation, the step (based on
my understanding) is somewhat like this :
1. Install Kamailio. I will use the step by step here :
http://kamailio.org/dokuwiki/doku.php/install:kamailio-1.5.x-from-svn
2. Then, using dipatcher module, I will configure it using
this guide here :
http://kamailio.org/dokuwiki/doku.php/asterisk:load-balancing-and-ha
Then modify the dispatcher.list file to match the IP address
of my asterisk servers :
/1 sip:192.168.2.2:5060 <http://192.168.2.2:5060>
<http://192.168.2.2:5060>
1 sip:192.168.2.3:5060 <http://192.168.2.3:5060>
<http://192.168.2.3:5060>/
Am I missing some steps?
Do I also need to configure dialplan or any other file at
Kamailio load balancer? Or those two steps basically done it
all for simple load balancing configuration? Thanks for your
responses.
these steps are ok if you do not deal with NAT. If yes, then
things get a bit more complex, you need PATH support on load
balancer, but AFAIK, Asterisk does not support it -- maybe I am wrong.
Cheers,
Daniel
