<p>Hello,</p>
<p>for the records, there is a minimal config example in the repo:</p>
<p> *
<a href="https://github.com/kamailio/kamailio/blob/master/misc/examples/mixed/kamailio-minimal-anycast.cfg" target="_blank">https://github.com/kamailio/kamailio/blob/master/misc/examples/mixed/kamailio-minimal-anycast.cfg</a></p>
<p>Maybe it is useful for a starting point, although I think it
targets use of UDP.</p>

When designing a Kamailio
deployment for several thousand
plus clients,<br>
there are many factors to
consider... including network
topology, future<br>
growth plans, high availability,
redundancy, etc.<br>
<br>
The quick answer top your question
is: It depends.<br>
<br>
There are many discussions and
presentations made over the years<br>
including some posted to the
kamailioworld youtube channel<br>
(youtube,com/c/kamailioworld) as
well as slides regarding large
scale<br>
deployments (such as 1&1).<br>
<br>
With best regards,<br>
