8. SIPNOC 2015 NNI Super-Session Introduction

Presented by Richard Shockey, Shockey Consulting and the SIP Forum.

This session will discuss the impact and details surrounding the impending official ratification of the NNI Interconnection Routing and IP NNI Profile reports by the SIP Forum/ATIS NNI Task Force.

This IP-Network to Network Interface (NNI) Joint Task Force is a cooperative effort between the Alliance for Telecommunications Industry Solutions (ATIS) and the SIP Forum that has been meeting regularly to define specifications to support SIP-based Service Provider to Service Provider IP Interconnection. The Task Force is comprised of telecommunications technical experts representing a range of telephony service providers and suppliers, both large and small, which serve both consumers and businesses.

As Service Providers introduce and expand IP-based service offerings, there is increasing interest in identifying the opportunities for the industry to facilitate IP routing of VoIP traffic using E.164 addresses.

Recognizing that IP traffic exchange is developing as an overlay to existing TDM interconnection and will be implemented by different service providers with varying timelines, the purpose of this report is to:

1. Provide an overview of in-use and proposed architectures with the provisioning processes and calls flows to facilitate the exchange of VoIP traffic associated with IP-based services using E.164 addresses.
2. Present comparative characteristics that may be useful in understanding the approaches.
3. Consider how such in use and proposed solution(s) may be adopted and/or coexist, and evolve for transition to a future integrated registry envisioned at the FCC Numbering Testbed Workshop.

The IP-NNI Profile Report defines a reference architecture and specifications for both the protocol and media as it appears “on-the-wire” at interconnect points.
