On June 15, 2010, Sprint Spectrum LP, d/b/a Sprint PCS and Nextel West Corp. informed the Missouri Public Service Commission (PSC) that they will elect third-party mediation to resolve a dispute with AT&T Missouri. On June 8, 2010, AT&T filed a complaint with the PSC seeking over $14 million dollars in payment from Sprint and Nextel. AT&T alleged in its complaint that Sprint has refused to pay termination charges for interMTA wireless traffic since 2007 when AT&T disputed the parties’ intraMTA/interMTA billing factor. Under the parties’ interconnection agreement (ICA), intraMTA traffic is to be exchanged at the reciprocal compensation rate, while interMTA traffic is subject to access charges. AT&T specifically claimed that Sprint has been delivering interMTA traffic over trunks dedicated to local traffic to skew the billing factor. In response, AT&T unilaterally instituted a new billing factor it claims accurately reflects the jurisdictional breakdown of the traffic, but Sprint has refused to apply it for the last two and a half years. Docket IC-2010-0358.
