Method Detail
doAuthenticate
public boolean doAuthenticate(String user, AuthorizationHeader authHeader, Request request)(Code)
Check the response and answer true if authentication succeeds. We are making simplifying assumptions here and assuming that the password is available to us for computation of the MD5 hash. We also dont cache authentications so that the user has to authenticate on each registration.

Parameters:
  authHeader - is the Authroization header from the SIP request.
Parameters:
  requestLine - is the SIP Request line from the SIP request.
exception:
  SIPAuthenticationException - is thrown when authentication fails or message is bad



generateNonce
