8. Overview of the SIP Forum/ATIS IP-NNI Task Force
This is the introduction to the SIPNOC 2014 NNI Super-Session – Part One: NNI Overview and Protocol. Moderator: Richard Shockey. Panelists include Martin Dolly, AT&T; and Chris Wendt, Comcast.
IP Interconnection among service providers is significantly increasing as the Transition of the PSTN from SS7/TDM to SIP/IP networks progresses. Current deployments of SIP/IP in the core carrier networks have exposed operational and implementation differences on how IP for SIP traffic works ‘on the wire’. These differences complicate interconnection, and in some cases require ‘protocol normalization’ to achieve full interoperability.
This special session will provide an overview of the work of the ATIS/SIP Forum NNI Task Force and its mission to identify a baseline set of features that should be common to all IP-NNI implementations for voice service.
