Oracle USM Authentication Check

At this point, the Oracle Communications Unified Session Manager has received an MD5 hash from the ENUM server and an MD5 hash from the UA.

Failure to match the two hash values results in a 403 or 503 sent to the authenticating endpoint.

The following image shows the user authentication process.
