Inter-Carrier VOIP Call Routing An Inter-Carrier Interconnection Workshop was held in June 2008 in Washington, DC among ATIS members and the IETF, GSMNA, 3GPP, and ENUM LLC to further advance the work of the IVCR-FG. A follow-on Working Group between the participating SDOs and ATIS member companies to further advance the proposed call routing solution was held between June 2008 and February 2009.
Next Generation Carrier Interconnect To address the priority area of Next Generation Carrier Interconnect a workshop was held in February 2008 in Washington, DC to facilitate the development of a work plan to identify the short and long-term actions needed for NG-CI standards. Participants included leaders of the ATIS Committees. An NG-CI Roadmap for 2008-2010 was created to assist the ATIS Committees coordinate and complete issue resolution. A follow-on effort, the NG-CI Longer Term Items Working group, comprised of representatives from ATIS Member companies completed an assessment of potential issues for resolve beyond those initially identified.
In November 2007 ATIS held a Convergence Workshop in Washington, DC to further define actions arising out of the ATIS Exploratory Group on Convergence Report and Reccomendations with subject matter experts who served on the exploratory group and ATIS Committee Leaders.
In April 2005, representatives of ATIS member companies and the European Telecommunication Standards Institute (ETSI) TISPAN Committee convened in Herndon, Virginia, to discuss their respective standardization activities supporting the deployment of NGNs and next steps for collaboration. In March 2006, ATIS hosted a joint workshop with the International Telecommunication Union Telecommunication Standardization Sector (ITU-T) in Las Vegas, NV to discuss ongoing standardization activities for NGN. The workshop’s objective was to identify standards work needed to support ongoing viable businesses for all parties as NGN becomes reality and to enhance ITU-T and ATIS cooperation to further coordinate NGN standardization. A particular emphasis was placed on NGN requirements and standards objectives from a North American perspective and the relationship of these with the global standardization work of the ITU-T.
In September 2004, a Network Security Symposium was held in Washington, DC to present the ATIS Security Issues Work Plan. The working sessions for the two-day symposium included a discussion session on authentication and confidentiality, the security exposures of various messaging models and the security concerns when modern application protocols cross the boundaries between networks of different organizations. The attendees outlined proposed next steps for defining and addressing challenges ranging from “spam” messaging causing denial of service attacks to ensuring protocols and standards meet carrier-grade deployment.
