Level 3 submitted its final report on its trial of direct access to numbers Monday (http://bit.ly/1cjwOtM). It handled nearly 23,000 port-in requests, and 21 port-out requests, all of which were successful. Level 3 had zero routing failures, billing or compensation disputes, it said. “Level 3 was disappointed but not surprised that the major incumbent LECs and wireless carriers with which it sought to establish IP interconnection were unable or unwilling to support IP interconnection for purposes of the trial, even though IP interconnection among competitive carriers is commonplace,” it said.
