The newly-developed Ooma PureVoice HD technology is offering free U.S. calling with “the utmost voice clarity,” according to company officials.

Sound like just more marketing claims? Try it out for yourself with examples of HD Voice on the company’s website, so you can make up your own mind.

In a recent interview with TMCnet, Ooma co-founder Dennis Peng (News - Alert) said, “PureVoice has five components,” explaining that their products prioritize voice over other activities happening online, such as downloading videos. Not that you’d be surfing YouTube (News - Alert) while working, of course.

A brief rundown of what makes such voice clarity possible:

Wire-speed QoS. Even though Ooma uses only a fraction of the bandwidth of standard VoIP technology, the little bandwidth it needs, it needs absolute priority for. Ooma can prioritize voice packets without slowing down the rest of your network. This means if you are doing other things on the network at the time, it doesn’t compromise the promised HD voice quality.

Advanced voice compression. Ooma uses an advanced voice compression algorithm that reduces bandwidth consumption by 60 percent over standard VoIP technology.

Encrypted calls. Ooma uses the same encryption technology governments use to protect classified data (that would make Ooma even safer than your old landline).

Adaptive redundancy. Packet loss is the enemy of VoIP, it’s what makes calls sound “jittery” or fragmented. Ooma can detect packet loss on your Internet connection before you even hear it and automatically deploy redundant packets to boost the clarity of your phone call.

HD Voice. Thistechnology actually doubles the fidelity of your phone calls, company officials say, by capturing twice the speech information of a standard voice call (yes, that includes your landline), so “your voice will sound more natural than ever.”
