Is there plans to write a document that outlines how to deal with all
portability issues, both PSTN number portability and 8XX.  The complexities
of a 8XX call in the US networks is not caputured in the presented document.
An 8XX Call that is terminated to a PSTN Number that has been ported
provides three routing numbers LRN, Translated 800 Number in GAP C0, and 8XX
Number in GAP 00.  

What numbers would a SIP proxy need to complete this call?

What about billing or accounting how do these numbers map for that? 

Thx,
Nate Nelson
