   The Session Initiation Protocol (SIP) has seen widespread deployment
   within individual domains, typically supporting voice and video
   communications.  Though it was designed from the outset to support
   inter-domain federation over the public Internet, such federation has
   not materialized.  The primary reasons for this are the complexities
   of inter-domain phone number routing and concerns over security.
   This document reviews this problem space, outlines requirements, and
   then describes a new model and technique for inter-domain federation
   with SIP, called Verification Involving PSTN Reachability (ViPR).
   ViPR addresses the problems that have prevented inter-domain
   federation over the Internet.  It provides fully distributed inter-
   domain routing for phone numbers, authorized mappings from phone
   numbers to domains, a new technique for automated VoIP anti-spam, and
   privacy of number ownership, all while preserving the trapezoidal
   model of SIP.
