Choosing a VoIP vendor: A buyer's guide

This unified communications series discusses the evolution of voice over IP. Learn what to look for when buying VoIP products, and choose the right VoIP vendor for your enterprise.

Introduction

Voice over IP (VoIP) technology is quickly becoming a popular mode of voice communication, but choosing the right VoIP vendor requires understanding how voice technology has evolved to address current business needs. Modern Internet Protocol (IP) standards support combining voice -- traditionally delivered via time-division multiplexing (TDM) telephony -- with Web-based data streams. VoIP technology can help boost productivity and provides a point of entry for businesses that want to upgrade their legacy telephony systems to more versatile IP communications services.

This guide will walk you through the process of buying VoIP, exploring how VoIP evolved for the enterprise and what benefits it can provide for your business. The guide also looks at which features to consider when choosing a VoIP vendor, and finally compares the top VoIP vendors in the market, accompanied by product overviews.
