Abstract
Although VoIP is still in the relatively early stages of adoption, US
businesses are beginning to gravitate to preferred flavors of VoIP. Larger
businesses prefer IP PBX solutions, while smaller firms are quicker to adopt
broadband-based VoIP solutions. However, businesses of all sizes are reluctant
to rely upon VoIP exclusively for their voice communications needs.
This report examines US business VoIP deployments, planned deployments,
current and planned service providers/vendors of VoIP, and how multiple
solutions are often used to meet the voice needs of businesses. IP PBX, hosted
IP, broadband IP telephony, and voice-enabled IM are all examined, and the
overall distribution of these options is examined by size of business.
The distribution of IP vs. TDM voice lines among businesses that have adopted
a VoIP solution is explored. This distribution is also examined between the
various VoIP solutions chosen by businesses.
A 2006- 2011 unit and revenue forecast is provided for broadband IP telephony
and hosted IP solutions among US businesses. IP PBX line shipments for the
first half of 2006 are also provided.
