• On August 8, 2012, the Missouri Public Service Commission (MPSC) suspended the YMax Communications Corp. proposed revisions to its intrastate switched access tariff and established a prehearing conference for August 22, 2012. On August 3, 2012, AT&T Communications of the Southwest, Inc. and Southwestern Bell Telephone Company, d/b/a AT&T Missouri filed a motion to suspend and investigate the proposed tariff revisions. AT&T has filed comparable motions to suspend YMax’s proposed tariff revisions in other states, including New Mexico, Kentucky, Alabama, West Virginia, Maryland and Ohio. AT&T argued in its motion that YMax’s proposed tariff revisions would allow it to charge interexchange carriers for access functions not provided by YMax, and that despite “unambiguous guidance from the FCC, YMax’s tariff contains numerous provisions that make clear that YMax will be seeking to collect the full array of access charges, including end office charges, even though neither YMax nor Magic Jack provide the services and functions that justify those access charges.” Following a staff recommendation to suspend and investigate the revisions, the MPSC found that to “allow sufficient time to study the effect of the proposed tariffs and establish an evidentiary record, the proposed tariffs will be suspended” until October 9, 2012, or until otherwise ordered by the MPSC. Docket No. TO-2013-0042.
