Product Description

Free Calls with Your Home & Small Business Phones

Use your existing corded or cordless phone(s) and your broadband Internet to make and receive calls over the Internet for free (or at a very low-cost).

Via the OBi202's two (2) on-board phone connections, you have the power make and receive phone calls using VoIP services for a fraction of the cost a traditional phone company would charge. The OBi202 supports up to four (4) VoIP services like Anveo, Callcentric, or a multitude of SIP Internet phone services as well as calls to other OBi endpoints via Obihai's free OBiTALK network. The OBi202 also supports the T.38 fax standard for reliable facsimile calls over the Internet.

The OBi202 is equipped with a 2-port router with integrated quality of service (QoS). The OBi202 may be installed in a variety of network environments and/or locations where upstream voice traffic needs to be prioritized above other types of traffic like web surfing and uploading pictures and movies.

The OBi202 USB port serves multiple purposes when used with Obihai USB accessory products. Using the OBiWiFi Wireless Adapter, the OBi202 can be placed anywhere within range of an 802.11b/g/n access point. The OBiBT Bluetooth wireless adapter allows a USB-equipped OBi device to pair with a mobile phone so you can place calls and answer calls using any standard home phones connected to the OBi. The OBiBT works with most mobile phones using Bluetooth wireless technology. The OBiLINE adapter allows a USB-equipped OBi device to make calls to a Land-Line Service from Phones Connected to the OBi.

OBi202 VoIP Phone Adapter with Router, 2-Phone Ports, T.38 Fax - Supports: Google Voice & SIP (Unlocked)

I realize that this review is rather lengthy, but bear with me, as I think you'll find it worth-it! This is how I use the Obi202 to save $165/month (approximately: $2,000 per year):

I have a home-based business, so I needed at least 3 different phone numbers: Business line, fax number, and personal-business number. I also wanted a 4th phone number for "strictly-personal" calls to/from friends. Prior to buying the Obi202... it just wasn't financially possible to have-it-all.

I paid a major land-line company approx $120 a month to have 2 separate land-line phone numbers for business and fax, as well as home internet service. I also paid approx $85/month for unlimited cell/data service for my personal number. I used the cell for both personal-business (like when calling around for quotes on car insurance, or when needing a number to sign up for various online services), AND for strictly-personal calls to/from friends. I found that I rec'd a lot of spam calls on my cell phone when doing this, though!

So, when the recession business was affected, and I needed to cut-down on expenses. After hours of internet research, I chose to buy the Obi202 (over the Magic Jack, and others like it). I have been able to cut down the $205 per month internet/phone bills down to JUST $40 ($30 for internet (using Charter Cable) + $10 for cellular service). I haven't even factored in the savings reaped by no longer having to pay for long-distance calls to anywhere in the USA or Canada.

I had an OBi110 and soon after buying that I heard that OBi202 is going to be released, so I passed on the OBi110 to a friend.

This does the job as beautifully as OBI110 did, with great feature of two lines on one little amazing gizmo that OBi202 is. Everything was setup within 5 minutes and it's been great for the short 2 weeks I have had it.

Only small hitch I have had is that it produces this little electronic noise which I am told is from the conductors inside, perhaps if I move it away from me (it' at 2 feet right now) it will improve.. It's not too bad but it's there, comes and goes.

Have not tried fax yet, but love the clean little gizmo that this is.

Edit: Actually the noise is becoming annoying. I still haven't gotten rid of my VOIP.. Will call OBI tomorrow again, and might return if they say this is expected. OBI110 never had this

Edit2: I just hooked up 2nd GV line to Obi202. It did not take the 2nd line easily, i.e., although I added all of GV infor just like the 1st GV line Obi202 somehow did not connect 2nd GV account. I called the Support and the folks there were extremely friendly, called me back in 15 minutes and told me they fixed the setup at their end on my ObiTalk setup page. It's been working like a champ since then. I am changing my rating to a 4 Star now as the slight noise is still slightly unacceptable.

BTW, I also transferred my VOIP line to T-Mo and then to GV, I would say it was well worth the $20 + .99 cents I spent on the whole transfer process :)

Edit3: I am coming back to make it a 5 star review. Afetr moving my obi device behind my monitor somewhere with other 'stuff' like KVM, USB hub etc etc.. I do not hear the noise any more at all.

While there are several Voice-over-IP (VoIP) devices on the market, Obihai's offering stands out from the rest because of its nifty use of Google's GTalk protocol to make completely free outgoing calls. But rather than rehash all of the great qualities of this device, I thought to provide a little background on how exactly the Obi works since calling the mechanism as one using "Google Voice" doesn't describe the whole picture.

Google's telecommunication offerings actually consist of two products - (1) Google Voice and (2) the calling feature in Gmail which doesn't really have a specifically branded name, but which I'll call "GTalk" as the calling feature is part of the GChat functionality in Gmail. Google Voice is actually a rebranding of GrandCentral's call-forwarding service that Google acquired some years ago with its acquisition of GrandCentral. It is not a Voice-over-IP protocol, but rather a call-forwarding service that allows you to use one "front-facing" phone number to which you can attach a limitless amount of other phone numbers (and services) which will ring whenever someone dials that "front-facing" number. GTalk, on the other hand, is a true VoIP protocol which Google obtained through its acquisition of Gizmo5, a small VoIP company. When you use GTalk to make calls, you are in fact making a telephone call through the internet.

The magic lies in the marriage of these two services and is what Obi takes advantage of. Google ties one's Google Voice number to the GTalk service in Gmail so that all outgoing calls carry that number and all incoming calls to that number are routed properly.
