[SR-Users] Non-authentication setup of Kamailio

[Daniel-Constantin Mierla]

Hello,

not sure I really understood what you want to achieve, but 
authentication by kamailio is done only if you call route(AUTH) for 
requests (in case you based your config on default one) or, in other 
words, the auth/auth_db functions.

But then, be aware of impacts in security. Be sure the authentication is 
done by someone, being you or being the provider. For registrations, if 
they are handled by kamailio, you have to keep doing authentication. So, 
just use conditions like:

if(is_method("REGISTER")) {
    route(AUTH);
}

For rtp, if the clients are on the same network, then don't engage 
rtpproxy, the audio should work. But if they are behind routers in the 
same network, you may still need to do rtp relaying.

Cheers,
Daniel
