5a. Industry Update -National Number Portability (NNP)

Presented by Gary Richenaker, Principal Solutions Architect, iconectiv, and SIP Forum Director.

Individuals and businesses value their telephone numbers and the ability to keep them – whether changing service providers, moving from one neighborhood to another, or relocating across the country. The FCC is going to issue a Notice of Proposed Rulemaking (Notice) and Notice of Inquiry (NOI) on how best to move toward complete nationwide number portability (NNP) to promote competition between all service providers and to encourage the efficient routing of calls throughout the network. The FCC wants to remove the Commission’s “N-1” requirement to allow carriers flexibility in conducting number portability database queries to promote NNP and efficient network routing and also to eliminate the Commission’s dialing parity requirement as it applies to interexchange service to remove barriers to NNP and better reflect the competitive realities of today’s marketplace.

Decisions reached on these issues will have significant impacts not only to call routing but also on non-routing issues including the issue that porting TNs out-of-state raises questions of regulatory and service provider responsibilities, liabilities, and numbering resource management.

The is the first of two sessions that explore the current status of FCC activities, industry efforts to address the routing issues as well as a discussion on different proposed approaches for implementing Nationwide Number Portability (NNP) and their impacts.
