I love VoIP phone services. Unlimited long distance at half the price of landline phones but with four times the features. What’s not to love?
A new generation of voice over Internet Protocol (VoIP) phones, routers and other equipment are nearly idiot-proof to install and use by both consumers and businesses.
But a funny thing is happening on the way to the VoIP revolution: Voice quality is getting worse, not better.
Conventional wisdom would hold that the Internet should be getting better at handling voice. But since March 2004, we’ve been testing nearly 1 million Internet phone calls by all sorts of customers from around the world. The results are disheartening, showing a consistent decrease in voice quality based on a commonly used Mean Opinion Score. The bottom line: The voice quality of one in five VoIP calls is unacceptable according to the data. If the trend continues, unacceptable calls will increase by 5 percent each year.
