Telecom Lead Asia: NTT is the world’s largest VoIP
service provider in 2011, with close to 7 percent of global residential and
SOHO subscribers. Comcast and France Telecom are in number two and three
Global service provider revenue from business and
residential/SOHO VoIP services grew 16 percent in 2011 touching nearly $58
The revenue that service providers derive from their
residential and SOHO VoIP subscribers still eclipses what they get from
businesses, but the business segment is growing about twice as fast, due in
large part to the surging popularity of SIP trunking and hosted VoIP and UC
services. Adoption of VoIP services across both the residential and business
segments continues to grow, and we expect strong global growth in VoIP service
revenue over at least the next five years,” said Diane Myers, directing analyst
for VoIP and IMS at Infonetics Research.
Infonetics Research said the number of seats for hosted
business VoIP and unified communications services will more than double between
2012 and 2016.
Revenue from SIP trunking service increased 128 percent
in 2011 as businesses adopt SIP trunking for flexibility, centralization of
resources and cost effective voice connectivity.
Hosted PBX and UC service revenue is up 33 percent and
seats up 44 percent in 2011 due to demand for cloud-based services.
The number of residential and SOHO VoIP subscribers grew
14 percent in 2011, to over 178 million worldwide, as more households opt for
no fixed-line voice connection.
Infonetics said businesses continue to migrate to VoIP on
their premises. T1 lines are still the most commonly used trunking service
today, and will be in 2014.
The use of SIP trunking is growing. Centralization,
easier management, and switching as part of infrastructure upgrade top the list
of reasons businesses are deploying SIP trunking
