Don't recognize the caller-ID? Just let your Ooma system pick up the call and listen in as the caller's message is played out through the speakers on your Ooma device. If it turns out you want to take the call, just pick up the phone and connect instantly.

Voicemail forwarding
Enjoy the ultimate convenience of having your voicemail forwarded to your email. Now you can listen to messages from your favorite mobile or desktop email client.

How Do We Compare?

Other phone companies nickel and dime you for local toll calls and long-distance, layering on mysterious fees, taxes, and surcharges for stuff you don't need. They bill you extra each month for caller-ID, call-waiting, and voicemail; features we, at Ooma, believe are fundamental to your U.S. calling rights.

Your one-time purchase of an award-winning Ooma system gives you free home phone service. You'll get the voice quality and ease of a traditional landline. That's because we've architected the Ooma system to partner with your existing home phones and high-speed Internet to deliver state-of-the-art calling without monthly bills.

There are no special handsets. No tricky calling codes to enter. No need to log onto a computer. Just pick up a phone and dial. It's that easy.

And for those who demand more, you'll get a 60-day free trial of Ooma Premier, so you can test-drive all of Ooma's innovative features, like multi-ring, personal numbers and private voicemail for each member of your home, with lots more on the way.

So if monthly bills are weighing you down, the answer is simple. Break free with Ooma.

I have been a Vonage customer for three years and suffered through all of their growing pains. At $25 a month though for unlimited service I thought I would check to see what other options were available and decided on giving Ooma a try.

The Ooma hardware is well designed, with thoughtful touches like a built in speaker for listening to voicemail and a brightness control so that you can turn down the brightness of the unit in a bedroom. The hardware comes wonderfully packaged like a product from Apple and includes just about any of the cords you might need to get everything connected with your existing service.

Setup was quite easy. You have to get online and activate the Ooma Hub unit by entering the MAC address on the bottom of the unit and telling Ooma what kind of service setup you are doing, such as whether you will use Ooma with an existing line, get a new phone number, etc. They don't even need your credit card and you are activated.

If you are getting a new phone number then you are essentially done at this point. You get a new phone number to use, and you connect the Ooma hub to your home network. Ooma recommends you put the Ooma hub between your Cable or DSL modem and your home router (if you have one). The reason for this is that it allows the Ooma unit to manage your outbound internet traffic and make sure your phone calls are optimized ahead of other traffic, so that phone calls always have priority, sound good and work properly.

If you have a more sophisticated home network router than can do traffic shaping, recognition of IP audio, etc (some of the top of the line D-Link models have these "QoS" features built in) then you can simply plug the Ooma hub into such a router and get good results.

Vine Customer Review of Free Product ( What's this? )
QUICK NOTE: Jason M. Page has a great review above my review...you should read it also.

UPDATED 12/17/2008
We dropped DSL and moved OOMA's to Cable Modem Service...

Hello All,
I bought an OOMA about 8+ months ago with one scout (added a 2nd system later on). Here is our setup.
1. NO LANDLINE required.
2. Using with Cable Broadband on Comcast.
3. Two OOMA Hubs (personal and business) and 2 OOMA Scouts.
4. 2 x 2 Line Panasonic Cordless system to use dual line capabilities.
5. Wired into home wiring so as to avoid unsightly clutter of hardware.

FIRST SYSTEM (Personal Use):
The OOMA hub is plugged in to our Apple Extreme Basetation, out of sight out of mind. Gave the OOMA internet access through the router and voila...phone service is live. NO land line is required. I know OOMA says you can use your existing land line, but it is not a necessity to use this system. They will issue you a new number or port your number over if you do not have or want a land line.

We took line one of the OOMA hub (marked home) and wired it into our home wiring (line 1 - our home is wired for 2 lines)....again very easy and no problem - the phones in the house starting working at once.

Challenge - we have a 2line phone system - so how can you use OOMA with a two line system and use the 2 line features of OOMA.

Since line one was wired and working we needed to get line 2 wired. I took the line 2 out of the ooma hub (marked WALL), wired into home wiring (line 2 jack in the basement), and used the ooma scout to complete the phone line network this system creates.

Line one was already going into the panasonic, so the scout now allowed us to plug in line 2.

First off , I want to say I have looked all over for any reviews I could find on the Ooma system before we made the purchase. I found numerous reviews in blog forms that almost looked as if they were started by Oomas competition, and not real life users. Many included false statements that you could verify simply by checking product manuals which are freely downloadable from Ooma without purchase. Most reviews from actual users are very good, with some exceptions of some that may jump in before getting all their questions and concerns answered first. Great reviews here and at some other major retail stores , take advantage of them we did. That is the main reason I am adding to reviews , hopefully to help others. I have tested our system with a few challenges to just see how far we can push the system with great results. These tests are below and may help some with similar questions.

We have cable high speed internet service with fast but not the greatest speeds, speed tested at 350-380 Kbps upload and 9850 Kbps download (checked at numerous speed test sites). My biggest concern was the ability to use our other connected products with the phone as well. I know the Ooma regulates the download and upload speeds to preserve the sound quality, but would it limit us too much? We have a PS3 , Wii , Netflix (watch instantly) , and cable phone service (soon to be removed) over and above the Ooma. Let me tell you we just hooked the Ooma up as suggested between our router and the cable modem and all is excellent. The hook up has been documented in other reviews so I wont go into great detail here, but it was very straight forward and quick. We were up and running in less than 20 minutes including activation online.
