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

Hi there,
I have never used Kamailio before but want to investigate if if will
work in my scenario before I invest time to learn it.
I am the administrator of a small Wireless ISP. We do not provide SIP
channels to our customers, we rather let them choose a service
provider of their choice. Currently our customers are using two
different providers.
Since we are using ADSL with only one static IP we sometimes run into
issues at the providers side with one way audio when our clients make
a call to another client which is using the same service provider. I
assume this is because of NAT. Since the RTP traffic actually leaves
our network and then comes back to the other client the quality of the
call is not as good as phoning a non client from the network.
I want to know if it would be possible to setup Kamailio to keep the
internal network calls traffic from leaving the network, and also
allow free phone calls on our network. To do this we would require the
authentication to take place on the service providers sip server and
not on Kamailio. Kamailio would only do routing of the traffic and not
worry about authentication.
Would this be possible?
Regards,
Carel Burger
