<p>Hello,</p>
<p>I typically blend several modules to achieve your routing needs:</p>
<p> - permissions module with address table to detect if calls are
coming from providers or asterisk farm</p>
<p> - based on result use load balancer to send out to asterisk
farm</p>
<p> - or use pdt (if each provider has one gateway) or
mtree+dispatcher (mtree to translate from a prefix to a dispatcher
set id of the provider with many gateways) to send out to
providers</p>
<p>If least cost routing is needed towards providers, then you can
decide to use one of next modules:</p>
<p> - lcr</p>
<p> - carrierroute</p>
<p> - drouting</p>
<p>Cheers,<br>

<div>Hello</div>
<div><br>
</div>
<div>I am looking at the following configuration: </div>
<div><br>
</div>
<div>1/ voip providers, with different external sip servers,
will send calls to kamailio, that will dispatch them to
asterisk servers, with load balancing & failover. The IP
of the asterisk servers are known and fixed.</div>
<div><br>
</div>
<div>2/ the asterisk servers will also place calls, going
through kamailio, that will dispatch them to the voip provider
sip servers, based on R-URI / Prefix.</div>
<div><br>
</div>
<div>I've achieved #1 with dispatcher module, I've seen
carrierroute module that can achieve #2, but I dont really
grasp how to put the two together.</div>
<div><br>
</div>
<div>I have the feeling that #1 can also be done with
carrierroute, and that I only need to check if the 'from'
domain is one my asterisk, and chose a different routing
table, but I dont see how to do that</div>
<div><br>
</div>
<div>is that a valid approch ? where should I look to do that ?</div>
<div><br>
</div>
<div>thanks</div>
