Cable telephony rang up $5.6 billion in '05
Global cable telephony service revenues rose from $4.5 billion in 2004 to $5.6 billion in 2006, according to new figures from In-Stat.
In-Stat, a research firm that shares the same parent company as CED, projects that cable phone revenues will hit $10 billion by 2009 as VoIP service penetrations deepen.
By the end of this year, In-Stat expects cable VoIP to reach almost 7 million homes, with about 4.4 million in the U.S. alone.
In addition to brining voice under the IP umbrella, In-Stat noted that costs remain a big advantage for VoIP over traditional circuit-switched services. According to In-Stat's analysis, VoIP provisioning costs are between 17 percent to 25 percent lower than they are for circuit-switched voice services.
