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.
