<p>Hello,</p>
<p>dns naptr is ok for locating servers as long as you control the
local infrastructure and make sure dns changes propagation is done
right.</p>
<p>An alternative would be using dispatcher module as a load
balancer. It has a lot of features for this use case, different
distribution algorithms as well as probing the servers (CBx) to
see which one is available.</p>
<p>If the perfomrance is the concern, keeping most of the processing
inside the kamailio is a good choice.</p>
<p>Cheers,<br>

<div>Hello Kamailio users,<br>
<br>
</div>
I'm working on a sip infrastructure, with opensource
technologies, and of course Kamailio will run on my new
infrastructure :)<br>
<br>
</div>
Kamailio will be my central routing engine, between SBC
(running on asterisk), and somes boxes (asterisk too) where
customers will be registred. Please find below my future
infrastructure:<br>
<br>

<div>Kamailio high availabality will be done with loopback
address and BGP in two datacenters. SIP carriers will be
connected to SBC and customer to one CB.<br>
<br>
</div>
<div>I have made some tests with kamailio, and i use LCR to
route call from CB to SBC, using wheigt and prorities to
send call to carriers.<br>
</div>
<div>Then, when a call arrived from carriers, i use DNS NATPER
lookup to find the right CB box.<br>
<br>
</div>
<div>CB HA is done using DNS SRV. So user is registred at one
location, and only one. No location sharing beetwen boxes.<br>
<br>
</div>
<div>I have some question concerning my architecture, and
technologies used to routing call.<br>
</div>
<div>Is LCR is the best option for routing call between
multiple carriers ? DNS NAPTER is a modern solution to find
an endpoint on this architecture ? Existing a better way to
route call with kamailio, for exemple rt-json and curl ?<br>
</div>
<div><br>
</div>
<div>
<div style="text-align:left">In my point of view, kamailio
should be a routing engine, using internal technologies,
to maximise performances. Less work with kamailio and
external app, best performances in sip routing. Is it the
good vision ?<br>
</div>
<br>
</div>
<div>Thanks in advance.<br>
