Thanks Alex for you reply.
I understand the dispatcher module can be used to load balance inbound requests.
But my questions is more related with outbound requests thru Kamailio.
Are you saying that in-dialog request can be routed automatically by Kamailio to
the correct Asterisk instance on the back end ?
And this is included in the stock config ?
I was just looking for an example.
Thanks,
