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.
