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.

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.

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.
