I know Jan won't be happy for this question because it may look simple. But I have tried everything I can and after failing I decided to ask it here.
I have realized that SER checks the username and password when a UA sends a REGISTER command but it doesn't check the password when a user sends a INVITE command.
This makes SER accept calls from people who did not even register. This is true because my GATEWAY doesn't register with SER but I can make calls from PSTN to my IP network.
So, my question is: HOW do I instruct SER to check the username and password of the CALLER?

No, I am fine with any question as long it is related to ser.

Yes.

Yes, you must accept such calls otherwise people who are, for example, registered at another proxy, won't be able to call your registered users.

if (method=="INVITE") { if (!proxy_authorize("your.domain", "subscriber")) { proxy_challenge("your.domain", "0"); break; }; };

You have in your cfg. file something like: if (method=="REGISTER") { if (!www_authorize("iptel.org", "subscriber")) { www_challenge("iptel.org", "0"); break; };
This will challenge only the registers. Change if (method=="REGISTER") to if (method=="REGISTER" || method=="INVITE") a.s.o.
Note however that you will be able to receive calls only from users registered with your proxy. If you plan to allow only "authorized" requests be carefull not to challenge ACKs and CANCELs (they must not be challenged), e.g: if (method!="ACK" && method!="CANCEL") { [...]

There is a special measure for that in auth module, it will never challenge ACKs and CANCELs, it will always return that the authentication was sucessful.
