OOMA Office brings enterprise-style VOIP services to SOHO and SMBs

OOMA Office brings enterprise-style VOIP services to SOHO and SMBs

Summary: OOMA's solution for small businesses is a multi-line subscriber VOIP service with a corporate-class call attendant and integrated voicemail that's affordable and easy to use.


I've been a user of OOMA's Voice over IP products for home telephony since they shipped their first product in 2009. Ever since, I've been POTS-free. OOMA's service is extremely reliable and I've been very happy with their call quality in the four years I have been using their service.

I eventually graduated from their first-generation product to the Telo, which is a slicker-looking solution that allows for cell phone integration/call unification via the use of Bluetooth and also provides for the use of special DECT 6.0 handsets which eliminate the need for regular cordless phone base stations to be plugged into the system's analog RJ-11 (POTS) telephone port, thus resulting in much higher audio quality.

The Telo, while an excellent product for residential use, has its limitations. It is not, by design, a multi-line, multi-extension system suitable for a small business type of environment where each handset can be tied to its own phone number.

And while the Telo has built-in voicemail, it does not have a call attendant with a company directory, if you wanted to give callers the impression that you were a much larger company than you actually were.

Despite the avaliability of the Telo's "Instant Second Line" premium service, if you needed two VOIP lines, each with its own phone number, then you needed two Telos.

That's exactly what I did for the last few years -- for our "Home" line I had one Telo attached to a Panasonic base station that my wife used which communicated with a couple of 2.4Ghz handsets, and for my business line, I had another, connected to two OOMA HD2 DECT 6.0 handsets.

The new OOMA Office solution takes this one step further. You can have up to five VOIP lines, each with their own phone number, connected up to four phones and one FAX line, or five phones and 15 virtual extensions for extending your business to remote employees that may be mobile or home-based. 

To accomplish this, the OOMA Office base station communicates with a wirelessly connected remote device called a "Linx" which plugs into an electrical wall socket and is paired via DECT 6.0 to the base. You plug a regular desk phone or a wireless handset base station into the Linx to make your actual calls. The Linx devices can also be used with the residential Telo system.

The basic OOMA Office starter kit ($249.00) comes with two Linx units, so that means you can have up to 3 lines if you include the built in port on the base station.

It supports an additional two Linx units which are sold as accessories. The base station hardware is actually capable of supporting 10 phone lines over a single broadband connection, but right now the firmware can only support four Linx units and the internal POTS connector.

Like the Telo the OOMA Office has an easy, web-based provisioning system for activating the service, configuring the voice attendant and phone extensions, porting existing telephone numbers if desired and provisioning VOIP lines, each of which costs $19 per month for unlimited calling in the US and Canada.

This is different from payment model in that the residential Telo is sold, which is a single $249.00 purchase for lifetime unlimited calling in the United States for a single line, and other services are upsold as premium enhancements.

The $19 per month for each OOMA Office line covers essentially all the premium upsells that were sold for the Telo, plus of course a caller attendant/automated receptionist, personalized voice mail, customized hold music/announcements (you can upload any MP3 under 5MB), conference bridging, virtual extensions, ring groups and call forwarding per line.

These are the kind of services that used to require much more expensive VOIP-enabled IP-PBX (Internet Protocol-Public Branch Exchange) systems that start at thousands of dollars and required specialized and vendor-specific phone hardware.

I think the OOMA Office is an excellent solution for a small business, one which could save you a lot of money in phone bills, but it is probably overkill for residential use, in which case I think their Telo product is much more suitable.

However there are a few things about the Office solution that currently annoy me. First, the current firmware only supports four Linx devices. As I understand from the company's product development team, this will eventually be expanded to handle ten Linx units with a future software update. The company is also working on "Stacking" of base stations so you can have the building blocks of a much larger system.

Additionally, the HD2 DECT 6.0 handsets and the Bluetooth adapter accessories from the Telo are not currently compatible with this solution although support is also forthcoming in a future firmware update.

The one feature that is currently lacking that I most would have wanted from a solution like this is a softphone application that could run on Windows and the Mac, which would allow the use of products like Logitech's H820e/H650e high-definition audio headsets to connect to the base station over the LAN or WiFi network.

This is still theoretically doable with the use of an inexpensive analog terminal adapter for each line and any number of SIP clients for Windows and Mac, but I would have preferred a more integrated solution. As I have been made to understand, this is also something OOMA is also looking into releasing as a future software enhancement.

Overall I think OOMA Office is an excellent product, as well as a great service value for small businesses even with its current limitations. But as the product is software upgradable, I'm expecting its capabilities to improve considerably over the course of the next six months to a year.

  • Never Heard Of Asterisk?

    All those features that supposedly required "thousands of dollars" have been available through Open Source software running under a Linux OS on commodity PC hardware for getting close to a decade now.
    • Thousands of dollar is for hours of setting up Asterisk and Digium cards

      All my machines at home are linux, I have always wanted to set up Asterisk at home, however the cost of Digium cards and the time will exceed the initial cost of 299$ for the small office version.

      The only plus side of setting up asterisk is that you can charge for the skill once you acquire it!
      • Re: Thousands of dollar is for hours of setting up Asterisk and Digium card

        You don't need any “Digium cards” to do VoIP or connect SIP phones. For analog or ISDN connections, there are even cheaper third-party cards which work with Asterisk drivers. So I still don't know where “thousands of dollars” comes from.
  • early adopter here too!

    I love my Ooma at home and have had it since early 2010. Granted, I rarely give out my home number, but the fact that I have a "land line" and pay literally $0/mo for it gives me all the negotiating power I need when my cable/cell providers try and bundle me in to a home phone service. "I have one that costs me $0." "really? what one is that?" "ooma." "oh." :)

    love it.
  • Obihai Instead of OOMA

    I tried OOMA and hated it. I did not find the call quality to be up to par and could not stand the annoying jingle that played every time I picked up the phone. An Obihai with Google Voice works great. I get my voice mail messages delivered to my email inbox and there is no monthly service charge as there is even with OOMA's "free" service. I also disliked the answering machine on the OOMA. It has been at least 12 or 13 years since I used one of those, and I don't plan to start using one now.
  • Ooma Coupon

    I found a coupon for a refurbished Ooma Telo for just $99.99 at the Ooma website:
  • Do not buy Ooma Office

    We bought Ooma Office a week ago and were very excited when we received our hardware and registered online.

    Our first disappointment was the bate and switch tactic of Ooma. The promo video uses an example with “Claire’s Cupcakes” and says Ooma Office redirect calls, “for Claire, press one” as one would expect from an office phone system. What the video does not say is that “for Claire, press one” is an extra $9.99 a month and “for Jane, press two” is an extra $9.99 a month and “for Jill, press three” is another extra $9.99 a month etc…

    If you do not buy extensions you pretty much paid $250 for an answering machine.

    Then, the problems started. First, we got a 404 error when trying to access the “virtual receptionist” settings on our account. Then we found out that anyone calling our Ooma Office got cut off after 20 seconds.

    Customer support is a total disaster. Calling customer support ends up in the Philippines where you are greeted by totally clueless people who only know a few basic things. Beyond that, the only thing they are capable of doing is submit a ticket and tell you not to expect any resolve before 24 to 48 hours. SAY WHAT?! 24 to 48 hours????

    Well, nothing happens even after 48 hours. When asking to speak to a supervisor you will be redirected to speak with a Filipino supervisor and his crying baby.

    We were so disappointed with the customer support by phone that we tried our luck by e-mailing Ooma, only to receive a useless e-mail telling us we have to call customer support.

    After a week of irritation and useless tickets, phone calls and e-mails, we finally shipped the Ooma Office back to Palo Alto for a refund and decided to pay a bit more and go with Verizon’s Virtual Communication Express. No more calls to the Philippines, no more Ooma.

    I would highly discourage anyone from buying Ooma.
