[Users] Rejecting SUBSCRIBE/NOTIFY messages

Hi Andreas,


According to the rfc, it should be valid:

21.5.2 501 Not Implemented

   The server does not support the functionality required to fulfill the
   request.  This is the appropriate response when a UAS does not
   recognize the request method and is not capable of supporting it for
   any user.  (Proxies forward all requests regardless of method.)

   Note that a 405 (Method Not Allowed) is sent when the server
   recognizes the request method, but that method is not allowed or
   supported.



Now, how the UAC will handle the response, it is a different story :-)
You will need to test for each UAC.


Regards,
Ovidiu Sas
