2 North American Numbering Council (NANC) - J. Scott MarcusSlide 2December 4, 2004 Technology, the Internet and the Demand for NANP Numbers n Factors that might decrease demand for numbers n Factors that might increase demand for numbers n The transition to the brave new world

3 North American Numbering Council (NANC) - J. Scott MarcusSlide 3December 4, 2004 Factors That Might Decrease Demand n Huge interest in Voice over IP (VoIP) u Conventional phone numbers? u Use of SIP addresses? n What is a phone call? u VoIP -> Everything over IP u Telephone -> intelligent device n Decreasing relevance of geography to numbers. n Short messages (SMS)

4 North American Numbering Council (NANC) - J. Scott MarcusSlide 4December 4, 2004 Factors That Might Increase Demand n A multiplicity of services. u Wired, wireless, Internet, … u Substitution of calls, but not of services. n ENUM – a mapping from telephone numbers to electronic services u Associates a subscribers phone number with a ranked list of Internet-based services that can be used to reach him/her. u ENUM requires no changes to the North American Numbering Plan, nor to international E.164 numbering.

F Wireline – call a PLACE F Wireless – call an INDIVIDUAL u Will people simply use phone numbers that they already have? u Will people demand new individual numbers?

7 North American Numbering Council (NANC) - J. Scott MarcusSlide 7December 4, 2004 In the Long Run n Will phone numbers become less important over time? n Or will they simply take on a somewhat different meaning?
