www_authorize is used?
It depends. A proxy (ser without pa module) forwarding SUBSCRIBER will
use proxy_auhorize, presence server (ser with pa module) will use
www_authorize.

what is
the difference between www_authorize and proxy_authorize ?
www_authorize is usually used when the entity generating it is the
final destination of the request. Registrar uses www_authorize, for
example. When ser reiceives a REGISTER, it will not forward it
anywhere but it will process it internally using save("location"). In
this situation www_authorize should be used.
When ser receives an INVITE, it will (optionally) look up the Request
URI in the location database and then forward it. In this case
proxy_authorize should be used because ser will forward the request.
The only difference between the two commands is the name of header
fields used for digest challenge and response.
