RE: [dispatch] VIPR - proposed charter version 3

["Roni Even" <[e-mail]>]

Mary,
When I read the charter it is not clear why from the first paragraph you
deduct the second paragraph.
If the first paragraph will say
" The goal of this working group is to enable inter-domain communications
over the Internet, using protocols such as SIP, while still allowing people
to use the called person assigned circuit switch phone number for
identifying the person with whom they wish to communicate. " 
It may look clearer.

Still this is based on the assumption that using other ways to assign and
authenticate SIP phone numbers using central databases is not catching up
because the carriers object to implement it and not due to any other reason
like preferences of enterprises IT to use PSTN for calls because of better
quality of service and manageability.
