  1. ENUM Ad Hoc Meeting Douglas Ranalli Founder, Chief Strategy Officer dranalli@netnumber.com February 12, 2001

  2. History • June 1997: Unifi directory services program. • 1998 – 1999: Early work with voice messaging • EMA and VMA joint initiative. • Lucent, Nortel, Comverse, Siemens, Unisys, etc. • October 1999: NetNumber stand-alone • Raised $9.5 million VC funding. • May 2000: First production release • November 2000: ENUM compliant

  3. Current View • Pro competition – not against “e164.arpa”. • Clear value in ENUM as a technical standard. • Not convinced that an “exclusive” “e164.arpa” implementation is a winner for the industry. • NetNumber’s focus is on the adoption of ENUM in the market. • ENUM service provider.

  4. ENUM Challenges • Tier-1 Challenge: • “e164.arpa” is a distributed solution • Administration by every ITU Member State • No guarantee of efficient deployment • Tier-2 Challenge: • Tier-1 points to a single Tier-2 • No guarantee that an exclusive Tier-2 provider will provide access to NAPTR records.

  5. “e164.arpa” Market Risks • Time to market • How long will “e164.arpa” take to evolve? • Participation consistency • Will “e164.arpa” yield a global solution? • Policy consistency • Who gets to run Tier-2 under “e164.arpa”? • Will every country agree on a competitive structure? • Pricing consistency • Will pricing promote the growth of ENUM? • Will many small providers be efficient?

  6. Competitive Alternative Embrace three types of ENUM services • Private ENUM “e164.company.com” • Commercial ENUM “e164.com” • Public ENUM “e164.arpa” • ENUM Resolver isolates application. • Customer defines set of domains to query • Resolver returns full set of addresses. • Common Requirement • Validation of subscriber intent

  7. Will Competition Help? • Time to market • How long will “e164.arpa” take to evolve? • Participation consistency • Will “e164.arpa” yield a global solution? • Policy consistency • Will every country agree on a competitive structure? • Pricing consistency • Will pricing promote the growth of ENUM?

  8. Conclusion • Embrace competitive environment • Participate in “e164.arpa” if consistent with US policy. • Explore regulatory environment in US around “ENUM validation”.
