The Commission has used FCC Form 477 to collect subscribership information from  telephone service providers – the incumbent local exchange carriers (ILECs), competitive local exchange  carriers (CLECs), and mobile telephony providers – for more than a decade.  The Commission has  required interconnected Voice over Internet Protocol (“interconnected VoIP”) service providers to report  subscribership information since December 2008 because the use of VoIP technology is growing rapidly and it increasingly is used to provide local telephone service.  

This report summarizes information about telephone services as of June 30, 2010.  It demonstrates that  interconnected VoIP service subscribership has continued to increase while subscribership to traditional wired telephone services has declined.  We also update summary statistics for the mobile telephony subscribership information collected by Form 477.
