Internet congestion is the enemy of voice quality.

Hear for yourself how our competitor holds-up under 30% packet loss. Then hear Ooma call quality under the same conditions.

Ooma PureVoice™ HD technology delivers superior voice quality even under extreme conditions using a collection of advanced technologies only Ooma can provide.

Here’s how the magic happens:

Advanced voice compression

Ooma uses an advanced voice compression algorithm that reduces bandwidth consumption by 60% over standard VoIP technology. This leaves you with more bandwidth for all your other online activities.

Wire-speed QoS

Although Ooma uses a mere fraction of the bandwidth of standard VoIP technology, the bandwidth it does use must be an absolute priority. Ooma prioritizes voice packets without slowing down the rest of your network so you can enjoy crystal-clear calls even while uploading video clips.

Encrypted calls

Ooma takes your privacy seriously. We use the same encryption technology governments use to protect classified data (which makes Ooma even safer than your old landline).

Adaptive Redundancy

Packet loss causes phone calls to sound stuttered or garbled with standard VoIP technology. Our sophisticated algorithms 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

Ooma HD Voice technology doubles the fidelity of your phone calls by capturing twice the speech information of a standard voice call (yes, that includes your landline.) When you and the other caller use an Ooma handset, or any HD compatible phone, your voice will sound more natural than ever.

Sophisticated technology meets elegant design.

The Ooma Telo is no dumb adapter. It's actually a small, networked-managed, secure Linux computer packed with processing power to keep your calls clear and reliable.
