[VIPR] Fwd: I-D Action: draft-jennings-vipr-overview-04.txt

There is no substantial changes in this document - just updating a
couple references to keep the doc alive.  At this point, it is not
clear to me what the plan is for the VIPR WG or any of the documents.
There had been some discussion of publishing some of the documents as
"this is what's been implemented by Cisco" as informational, I guess.
Or whether the plan is just to close the WG.  But, again, I figured it
wouldn't hurt to keep the document updated for now.

BTW, I think this document could be revised as informational and
published as is.

Regards,
Mary.

Abstract:
   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 involving the Public Switched Telephone Network (PSTN),
   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 SIP anti-spam, and privacy of
   number ownership, all while preserving the trapezoidal model of SIP.
