Title: [Speermint] New Draft: SIP Interconnect Guideline

I took a quick look at the I-D and want to be sure I understand what's being said about  called user identification. In Section 4.2.1 is the identification of the rn in  the case of a ported number just for sub subsequent interworking back to SS7/circuit switched networks or something else? I tend to think of ENUM-based routing mechanisms as being portability corrected to begin with so number portability info should only be required where subsequent interworking has to take place.

Subject: [Speermint] New Draft: SIP Interconnect Guideline

All,

We have submitted a new draft beginning a 
process for defining a SIP interconnect guideline for peering.   Of 
the operators I have spoken with regarding their experiences with peering, SIP 
interworking is the most challenging process to work through.  Establishing 
a guideline will be a fundamental step in enabling SSPs to peer quickly, 
efficiently, and dynamically.

A New Internet-Draft is available from the 
on-line Internet-Drafts directories.

As Session Initiation Protocol (SIP) peering becomes more 
widely
accepted by service providers the need to define an 
interconnect
guideline becomes of greater value.  This document takes 
into
consideration the SIP and commonly used SIP extensions, and 
it
defines a fundamental set of requirements for SIP Service 
Providers
(SSPs) to implement within their signaling functions (SFs) 
or
Signaling Path Border Elements (SBEs) for peering.
