[SR-Users] [Kamailio]: INVITE Authorization

[Spinov Evgeniy]

Hello.

I have Kamailio ( K in further ) and 2x Asterisk boxes ( A1 and A2 in
further ) configured, so UAC registers at K and when it sends a call,
it's routed to A1 or A2, balanced.

The problem is, that I cannot find how to authorize INVITE requests, so
unregistered UAC could not send INVITE requests. Simply cannot find
anything. 

I'm making registration, using www_authorize() and checking all INVITES
with proxy_authorize(). Just after kamailio is started - everything
works fine and as planned: registered UAC can call and not registered -
cannot. But after aproximately 40 seconds everything is stopped. Not
calls passed and everybody receives 407 Proxy Authorization is required.

So, the question: how it is correctly to verify that incoming INVITE on
K is authorized? It seems to me that I'm doing that in wrong way.

Thank you.
