Broadband IP telephony is used to transport voice calls over an IP network, and, if need be, to connect to the PSTN. This looks like traditional telephone service to the end-user and, in the case of cable VoIP service, is often marketed as a “digital” voice service, leaving many users unaware that they are using a VoIP service. This has been a popular form of VoIP in both the work-at-home and small business arenas, and that trend will continue according to new In-Stat research, which forecasts that the small office (1 to 4 employees) spend on broadband IP telephony will increase by 83% from 2010-2015.

Additional data includes:

• Traditional TDM is set to decline to just under $14.5 billion in 2015.
• Application-Based VoIP, will increase over 50% from 2010-2015.
• As a segment, mid-sized business (100 to 999 employees) spending will have the greatest growth, increasing in excess of 10% between 2010-2015.
