See a picture of the caller as the phone rings, search and scroll through contacts, and easily manage contacts using the My Ooma web portal.

Cutting-Edge HD Voice Clarity

The combination of the Ooma Telo and new Ooma HD2 Handset provides cutting-edge HD Voice call clarity by capturing twice the voice data to double the fidelity of standard phone calls, for richer, more natural-sounding conversations.

Superior Security and Range

The HD2 Handset uses the latest DECT technology, which guarantees call quality and security without interfering with your local Wi-Fi network. It also maximizes your handset’s range, allowing you to wander freely about your house while talking.

Hands-Free Calling

The Ooma HD2 Handset features a built-in speakerphone with loud and crisp sound. When you need to multitask, just activate the speakerphone or standard headset jack for a hands-free conversation.

Intercom and Baby Monitor

With the intercom feature, you can use multiple Ooma handsets like walkie-talkies to communicate with family members from room to room. Use the intercom to talk between handsets in HD, or remotely listen in using the baby monitor function.

Advanced Voicemail Features

The Ooma HD2 Handset helps you make the most of Ooma’s superior voicemail options. At the touch of a button, you can listen to your voicemail from anywhere in your house.

Detailed Call Log

The Ooma HD2 Handset’s detailed call log helps you keep a meticulous record of your phone history. It allows you to view all incoming calls, outgoing calls, and call duration.

With optional Ooma Premier service, users get access to additional advanced features:

Instant Second Line

The Instant Second Line feature is perfect for a busy household or home. When the line is already in use, you can simply pick up a second Ooma HD2 Handset and make or take a second call. Up to two separate calls can be made simultaneously.

Do Not Disturb and Send To Voicemail

If you’re screening your calls, you can activate the “Do Not Disturb” mode and forward all of your calls to voicemail. You can even redirect a call back to voicemail by pressing the “Send to Voicemail” button after you’ve picked up the phone.

Personal Number

With an affordable Ooma Premier subscription, you’ll gain access to the Personal Number feature. This feature allows you to create a unique phone number for everyone in the family. Multiple numbers can be mapped to the same handset, but you can make each number ring distinctively so you know who the call is for. Up to nine additional numbers are allowed.

Port Your Existing Phone Number

Ooma gives you the option of retaining your current telephone number for a fee. If you prefer to change numbers, you can choose a new number in almost any calling area in the US at no extra cost.

Ooma Mobile HD App for Android and iPhone

Save money on mobile calling by tapping into your Ooma account on the go. With the Ooma Mobile HD app you can use your Android or Apple iOS device to bypass your cell phone carrier and make calls using any Wi-Fi or 3G network.

Exclusive Web Portal

My Ooma is the online command center for your Ooma system.

Access My Ooma anywhere you have an Internet connection, even from your mobile smartphone.

Ooma PureVoice HD

In today’s connected home environment with Internet file sharing, video streaming, online gaming, and more, there’s a lot of network traffic that your voice calls will need to compete with. PureVoice HD technology allows Ooma to deliver clear audio even when substandard calling conditions exist. Ooma PureVoice HD Technology is composed of five key components:

  • Advanced Voice Compression: Ooma uses an advanced voice compression algorithm that consumes over 60 percent less bandwidth than standard VoIP technology. That leaves you with more bandwidth for your other online activities, and increases the likelihood that your voice traffic will be delivered.
  • Wire-speed Quality of Service: Even though Ooma uses only a fraction of the bandwidth of standard VoIP technology, those packets need to arrive without delay for optimal quality. The Ooma Telo prioritizes voice packets without slowing down the rest of your network. This way you can enjoy crystal clear calls even as you’re uploading your latest video clips.
  • Adaptive Redundancy: Network packet loss is the enemy of VoIP – dropped packets can cause voice to sound stuttered or garbled. The Ooma Telo detects packet loss on your Internet connection and automatically sends redundant packets to boost the clarity of your phone call.
  • Encrypted Calls: Ooma takes your privacy seriously. We leverage the same encryption technology that governments use to protect classified data to protect your conversations. This makes Ooma even more secure than the traditional landline.
  • High Definition Technology: HD Voice technology doubles the fidelity of your phone calls by capturing twice the speech information of a standard voice call. When you and the other caller both use an Ooma Telo Handset or other HD compatible phone, your voice will sound more natural than ever.

Which OBi Should I Get?

        Obihai have two telephone adapters, currently – The OBi100 and the OBi110. The two products function the same except for one feature. The OBi110 has a physical port for an analog line service. This port, labeled LINE on the OBi110, can be thought of as a gateway to a traditional phone service. The service can be from a land line carrier. It can also be from a VoIP service, when the phone port of the service provider’s device is plugged into the LINE port of the OBi110. This gateway functionality is useful for a number of reasons.

OBi110 LINE Port:

      – Allows you to keep your current land line service yet take advantage of the OBi device’s VoIP services.
      – Provides for an emergency calling services route when connected to a service supporting the same.
      – Acts as a gateway and bridge to the PSTN for calls originating on a VoIP service from a remote OBi device or soft phone.

The OBi110 & OBi100 Both Have:

      – One Phone Port: For connection to an analog cordless or corded phone
      – The OBi Phone Port Can Power All the Phones in Your Home
      – One Ethernet Port: For connection to an Internet router
      – Support for up to 2 Commercial VoIP services
