有关IMS SIP及Presence应用的RFC文档包

   Requests can reveal sensitive information about a UA's capabilities.
   If this information is sensitive, it SHOULD be encrypted using SIP
   S/MIME capabilities [11].

   All filtering-related security measures discussed in [2] MUST be
   followed along with package-specific security.
