Comcast's VoIP makes it a Top 3 telco

12.03.2009

That growth comes as telephone companies struggle to hang on to their landline customers. In 2008, AT&T, for example, lost 3.5 million wireline voice subscribers. Qwest also lost voice customers in 2008 compared with 2007. AT&T and others commonly say that their lost customers are giving up their landlines and migrating to mobile phones.
