As technical barriers are overcome market forces are bringing voice over Internet protocol (VoIP) market acceptance.  Momentum is accelerating as a result of improvements in DSP technology and VoIP operating system software.

Complete solutions optimize power, area, channel density, and high quality VoIP software.  Features support reliable, clear voice transmission.  Affordable solutions are built on density.  Rack mounted ports are targeted to service providers.  Routers need to operate efficiently to be useful to service providers. 

Scalability has improved, price points have dropped, and a full range of high quality voice features are available for a wide range of circumstances, from the low channel requirements of customer premise equipment to the high density, carrier class requirements of service providers.

VoIP service provider VoIP gateway markets are expected to have strong growth throughout the forecast period.  Voice over the Internet promises to make global communications a reality.
