Spam, defined as sending unsolicited messages to someone in bulk, is
   likely to become a problem on SIP open-wide deployed networks.  A
   number of solutions have been proposed for dealing with Spam for
   Internet Telephony (SPIT) and unwanted communication, for example,
   content filtering, black lists, white lists, consent-based
   communication, reputation systems, address obfuscation, limited use
   addresses, turing tests, computational puzzles, payments at risk,
   circles of trust, and many others.

   This document describes the big picture that illustrates how the
   different building blocks fit together and can be deployed
   incrementally.
