The probably you can use mtree to associate dids with ip addresses
(or dispatcher set ids).<span class=""><br>

<div> So if loadblancer send phone call on one server, but
user is not registred on this one, call is hangup/lost.<br>
</div>
<br>
</div>
I will use LCR for outgoing call. LCR will "help" CBx to find
best carrier following rules defined by administrators. LCR
can probe gateways ? I have set ping_interval etc but ping is
not sent by kamailio.<br>
</div>

I don't know if lcr can ping gateways. I know dispatcher does it.<br>

<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>

<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>
<br>
----------
--------------
-------- ----------------</div>
<div>| SBC1 | - - - - - | - - - -| kamailio1 |- -
- - - | - - - - - | CB1 |-----------------|

|- - - - -| -------- <br>
| SBCn |- - - - - |
-------------- | - - - - - | CBn |<br>

<br>
</div>
<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>
