Hi,

We are deploying a VoIP system based on Kamailio. The system is composed of load balancers, proxies, registrars, etc

What is the recommended transport protocol to use for internal communication (i.e. load balancer <-> proxy/registrar)? We started with UDP but we also see that Kamailio supports TCP and SCTP.

For information, at first stage, the UAs will communicate using UDP but we may need to use TCP in case messages are too large (we had such issues when using ICE).

Thanks,

Mickael
