Neustar Warns FCC Not to Expect Contingency Rollback; T-Mobile Adds to Telco Drumbeat

8, "there will be no contingency rollback (either automated or manual) to Neustar's database and services because the contractual and operational requirements necessary for such service would not exist," said the incumbent's filing Thursday to be posted in docket 09-109. Neustar offered in October 2016 to construct North American Portability Management's "preferred automated, reliable contingency rollback solution," the incumbent said. "Neustar estimated 6-9 months for development and a cost of approximately $1.5 million. The NAPM rejected Neustar's proposal on May 12, 2017. The current predicament--reaching the cutover deadline without the capability for a contingency rollback--was entirely foreseeable and is the result of poor decision making and planning on the part of the NAPM. To suggest otherwise is false." The FCC and NAPM didn't comment. T-Mobile was the latest telco to back the LNPA transition timetable and NAPM's contingency rollback plan. "Given the significant positive testing conducted by T-Mobile, as well as other service providers, we are optimistic that transition to the new LNPA will be successful," it said Wednesday, citing a "low likelihood of a catastrophic failure" requiring a contingency rollback to Neustar's Number Portability Administration Center. Other large carriers have made similar filings; Neustar and smaller providers voiced objections (see 1803140053, 1803130047 and 1803090031).
