The standards do not prescribe what Authorization headers a server will accept. However, the usual practice is that the "uri" value has the form "sip:UUU@DDD", where UUU is the user-part of the user's AOR and DDD is the SIP domain, the "realm" value is the SIP domain, and the "username" is UUU. Of course, the "digest-uri-value" that is used in the computation of the digest (RFC 3261 section 22.4) is the same as the request-URI of the request containing the header (which is different for different requests even if they originate from the same user).
