Atis and US National Exchange Carrier Association (NECA) have joined forces to launch a voluntary Joint National Call Testing Project (JNCTP). The project, to be co-administered by both Atis and NECA, will offer interexchange carriers, mobile carriers and VoIP providers the opportunity to identify call completion issues on calls destined to areas served by volunteer local exchange carriers. It also will allow these providers to capture network and routing data relative to call failures and to enhance internal network performance and/or underlying carrier performance as needed. Finally, where appropriate, it will facilitate cooperative trouble resolution efforts with originating, intermediate and terminating carriers. Information gathered during the JNCTP may be used by Atis and NECA to assist the industry with identification and resolution of call completion issues. Such efforts include the enhancement of member training and future revisions of the Atis Next Generation Interconnection Interoperability Forum (NGIIF) Intercarrier Call Completion/Call Termination Handbook, an Atis resource on new and existing industry standards to help ensure call completion.
