  Modified ? It should add them. According to the specification it is
  possible, if there are 2 digest challenges (distinguished by realm) in a 
  response then the user agent should generate two digest replies if it has 
  credentials for them and put them in the new message.

  SER will pick one of the digest headers, SIPURA should pick the other
  one and the message will get through.
