Major countries in Asia such as China, Japan, India and Singapore have taken significant steps for VoIP implementation for enterprises.

Why VoIP is on the Rise?

Voice over Internet Protocol (VoIP) is a technology that allows you to make telephone calls using a broadband Internet connection. It converts the voice signals into data for transmission over an IP network, and then reconverts the data back to voice signals.

There are several factors tip in the scales in favor of IP telephony. But the primary one is the trend towards a consolidated data and voice infrastructure as organizations look to reduce operational costs.

Also, an increasing need to replace traditional private branch exchange (PBX) systems has pushed businesses to look at alternatives like VoIP. With the current distributed IP phone solution, enterprises do not have to fuss over system breakdowns that once plagued the old PBX.

The implementation of VoIP system allows voice calls to be carried over the company's existing data network. The IP phone system has helped to reduce voice traffic and ease the maintenance.

The rise of VoIP among enterprises also because of the high growth of broadband connections to the home, improvements in quality of service, and hook-ups that allow VoIP calls over ordinary telephone handsets rather than clunky PC microphone systems.

VoIP services for now typically promise a significant cost savings, virtually wiping out charges for long distance and international calls. In addition, connecting phone calls over the Internet could eventually open the door to advanced communications services that tie voice together with e-mail, instant messaging and video conferencing.
