Hello,
I have 2 simple questions:
1. What is the difference between www_authorize and proxy_authorize functions?
2. Why is common to use 2 databases when using voicemail? I think that is more logical to use one (standard ser database) because it has all informations we need.
Thank you in advance, Milivoje

When a request comes to the SER proxy that it feels compelled to authenticate (like an INVITE or REGISTER) the *_authorize function creates a challenge and bounce the request back to the requester. I always use proxy_authorize, but I have also used www_authorize in the past. I believe you would use www_authorize if you were a UAC, and proxy_authorize if you are a UAS (User Agent Client|Server), but I do not know for sure.
I did have an issue with a specific UAC one time, I can't remember the make. It *would not* respond to the www_authorize and I had to use proxy_authorize for it. Since all the other UACs I mess with respond to either I decided to start using that instead.

RFC3261 distinguishes between authentication in intermediate hops like proxies (=proxy_authorize) and authentication in the final hop (the user agent server, =www_authorize).
For REGISTER messages, the proxy is usually the final hop. Therefore, you have to use www_authorize.
For all other messages, the proxy acts as intermediate hop and therefore proxy_authorize is the way to go!
