RFC Editor Note

RFC Editor, please make the following clarifying change in Section 4,
Security Considerations.
Old:

   This document is informational in nature, so it does not directly
   affect the security of the Internet. However, security is a basic
   requirement of this work. Section 2.1.9 contains security
   requirements related to the SIP-AAA interface.

New:

   Security is a critical requirement of AAA for the Session Initiation
   Protocol.  Section 2.1.9 describes the threats and security 
   requirements.  Section 2.2 elaborates on the authentication and
   authorization requirements.
