End-user ENUM: The LLC has created technical specifications that would allow the implementation of ENUM Tier 1A Registry services for countries that participate in the North American Numbering Plan (NANP) and the implementation of ENUM Tier 1B Registry services for the United States. In addition the LLC has drafted separate Request for Proposals (RFPs) that incorporate those technical specifications. Before issuing these RFPs, the LLC initiated a trial of End-user ENUM to ensure that there would be no outstanding technical issues in any future commercial offering in the United States. The LLC has finalized the End-user Trial Report and will make recommendations to and is seeking direction from US government agencies on proceeding with implementation. Hence, there is no specific timeline for any future activities in this space.
Toll-free ENUM: The LLC has started looking at how toll free numbers might fit into an ENUM implementation. This work is at a very early stage of development.
Provider ENUM: The LLC has adopted the End-user ENUM specifications to allow the implementation of a Provider ENUM Tier 0/1 Registry service to support the member companies of the LLC as well as other "service providers of record" that may be interested in participating. The LLC conducted a proof-of-concept trial of Provider ENUM and is has developed a Report of those trial results. The LLC has now issued the Provider ENUM Tier 0/1 Registry RFP, and hopes to be in a position to have a vendor selected and in beta-test in 2Q2008.
