 * 	9.5.1.  SIP-Authentication-Scheme AVP

   	The SIP-Authentication-Scheme AVP (AVP Code 377) is of type
   	Enumerated and indicates the authentication scheme used in the
   	authentication of SIP services.  RFC 2617 identifies this value as an
   	"auth-scheme" (see Section 1.2 of RFC 2617 [RFC2617]).  The only
   	currently defined value is:

   	o  	DIGEST (0) to indicate HTTP Digest authentication as specified in
      	RFC 2617 [RFC2617] Section 3.2.1.  Derivative work is also
      	considered Digest authentication scheme, as long as the
      	"auth-scheme" is identified as Digest in the SIP headers carrying
      	the HTTP authentication.  This includes, e.g., the HTTP Digest
      	authentication using AKA [RFC3310].

   	Each HTTP Digest directive (parameter) is transported in a
   	corresponding AVP, whose name follows the pattern Digest-*.  The
   	Digest-* AVPs are RADIUS attributes imported from the RADIUS
   	Extension for Digest Authentication [RFC4590] namespace, allowing a
   	smooth transition between RADIUS and Diameter applications supporting
   	SIP.  The Diameter SIP application goes a step further by grouping
   	the Digest-* AVPs into the SIP-Authenticate, SIP-Authorization, and

   	SIP-Authentication-Info grouped AVPs that correspond to the SIP WWW-
   	Authenticate/Proxy-Authentication, Authorization/Proxy-Authorization,
   	and Authentication-Info headers fields, respectively.

    Note: Due to the fact that HTTP Digest authentication [RFC2617] is
    the only mandatory authentication mechanism in SIP, this memo only
    provides support for HTTP Digest authentication and derivative
    work such as HTTP Digest authentication using AKA [RFC3310].
    Extensions to this memo can register new values and new AVPs to
    provide support for other authentication schemes or extensions to
    HTTP Digest authentication.

    Note: Although RFC 2617 [RFC2617] defines the Basic and Digest
    schemes for authenticating HTTP requests, RFC 3261 [RFC3261] only
    imports HTTP Digest as a mechanism to provide authentication in
    SIP.

   	Due to syntactic requirements, HTTP Digest authentication has to
   	escape quote characters in contents of HTTP Digest directives.  When
   	translating directives into Digest-* AVPs, the Diameter client or
   	server removes the surrounding quotes where present, as required by
   	the syntax of the Digest-* attributes defined in the "RADIUS
   	Extension for Digest Authentication" [RFC4590].
