3. MISSION The North American Numbering Council’s (NANC) Interoperable Video Calling Working Group explores how to facilitate the provision of interoperable telephone number-based video calling, which could allow increased use of video calling for both hearing individuals and people with hearing and speech disabilities using different, otherwise-incompatible equipment and services. The Working Group comprises a variety of stakeholders whose technical, policy, and regulatory backgrounds provide the knowledge necessary to refine and develop recommendations for achieving this goal. The Working Group is committed to providing the NANC a final report.

4. REPORT • Pursuant to the NANC Chair’s request, the Working Group meets weekly in an effort to prepare and ideally submit a final report to the NANC for approval. • Per the NANC’s directives, the Working Group final report ideally will: • Provide options for, and analyses of, any changes necessary in numbering or numbering administration to allow and encourage the deployment of telephone number-based interoperable video calling, including any changes to Commission rules, and any change, migration, or consolidation of existing numbering directories, including the TRS Numbering Directory; • Describe any recommended developments in technology, standards, or operations required to promote the deployment of telephone number-based interoperable video calling, including the incorporation of interoperable video calling in the implementation of NG911; and • Recommend next steps the Commission and industry should take to promote interoperable video calling services.

5. REPORT (cont.) As of March 21, 2019, the Working Group determined that the Working Group report should include recommendations on addressing, signaling/media and NG9-1-1. The Working Group also determined that the scope of the Report will likely include the ability to make point-to-point video calls, using ten-digit telephone numbers, across video service boundaries. This scope will focus on the ability of video calling users to • discover which of their contacts are video-capable, regardless of which service they use; • initiate and establish calls to users on another service; and • exchange audio and video and communicate across services. • The Working Group determined that multi-party video calling with screen sharing across services would be out of scope.

6. TIMELINE

7. NEXT STEPS • Members will continue to receive and deliberate on contributions related to the core issues in order to develop preliminary recommendations. • The Working Group will report on preliminary recommendations to the NANC, June 20, 2019. • A final report will be sent to the NANC for approval as quickly as possible.
