Hello again Henning,

I'm not looking forward to finding the configuration that will match my
requirements. The case studies that will inspire my thought  will be very
appropriate.
This is why I put Daniel's study/presentation about Kamailio LoadBalancer
https://www.kamailio.org/events/2013-KamailioWorld/23-Daniel-Constantin.Mierla-Load-Balancing-Load-Balancers.pdf
link in original email.

Regards,
Melek
