Which OBi Should I Get?

Obihai has four telephone adapters, currently - The OBi100, OBi110, OBi200 and OBi202. See the chart below for an overview of the product features. In essence, these products work with your phone in the same manner except for one key 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.

Good sound quality.
I've been using google voice with it, so all my calls have been free.
This product works great and is very easy to setup.

I configured the OBi110 to use Google Voice, and it completely replaced my home telephone service. With free long distance within the US, the device will pay for itself in savings in a couple of months.

Configuring the device was easy. The online documentation was decent, and I found a few other blogs with tutorials as well. I recommend using the obitalk web site for ease of configuration. The only problem is that it stores your Gmail username and password, so there's a certain expectation of trust that OBi will not misuse that information. Personally, I created a second Gmail / Google Voice account just for this product. Thanks Google!

Note: this product does NOT provide access to 911. If this is needed, it is available through several Internet phone service providers. I used CallCentric, which provides enhanced 911 for $1.50 per month. The OBi online wizard provides easy setup for CallCentric and other Internet phone services, and configuring the device to place 911 calls through this service was fairly easy.

Also, the call quality has been excellent. I cannot tell a difference in sound quality between the OBi / Google Voice and my previous PSTN service. I have not had any problems with dropped calls either.

Overall, this is a solid product and a great way to save some money by dropping the telephone company.

I have been looking for a simple solution that would allow us to setup and use Google Voice. Since asterisk 1.8 came out, I have been waiting for DD-WRT or tomatoes to integrate this in the router so I would not need a computer to run 24/7 to set up Google Voice.

Then comes Obi110 which solves this problem. The setup was very simple. If you don't want to store your GV credentials on the Obitalk.com you can set it up by logging on the adapter (just like logging onto the router). I did find it that if you do it this way, when you dial out you still have to dial "**1" (using profile1) then the number you want to reach. Maybe there is a way to get rid of this. But if you setup through Obitalk you can enable the prefix and dial just like in GV. You can also update the FW from Obitalk.

Everything is working as expected. Caller ID shows up correctly when you call someone. When someone calls the ID would show "+" then the number with no dash, something like this: +1234567890. My wife was on the phone for an hour and she said the quality was good. If you are looking into a simple setup (and almost plug and play) I would highly recommend the Obi110.

Update 12/10/11: Caller ID has been showing the correct format for a while now. Also, my unit died a few months ago. I called their tech support, they checked from remote and confirmed that it's dead. They sent out a replacement unit the next day! I just have to send the dead one back. Great customer service. Google voice is still free for 2012 btw.

I waited 6 weeks before writing this review. After looking at all the reviews@amazon.com, I bought this product . I set it up using google voice and sipgate. It was easy to set up. It works fine even with VOIP enabled home security system. It worked fine for 2 weeks. After 2 weeks of use, I encountered 3 main issues. 1) Every 2-3 days, I have to reboot the system. It was stuck and we were not receiving calls. It was frustrating experience for the family. Customer service promptly pushed the update. It did not help the problem. Later, customer service attributed the problem to google voice. 2) At times, caller on the other side can't hear you. If you hang up and call back. It works fine. Customer service blamed it on google voice. 3) call gets disconnected in the middle of the call.

If you visit customer forum, you will read that many customers are having similar problems. I need a reliable communication phone line. I am disconnecting from obihai 110 and signing back with vonage. If they fix these issues, I will go back.

I encourage you visit customer forum before buying this product. I feel that the reviews at amazon.com are based on very short term use.

First impression, I wish I had done this sooner!!! Second impression, okay never mind, never too late :)

okay, here's my feedback!

1. Made a new gmail account.

2. Chose a google voice#.

3. Now, come to Obi device ... unboxed it - read the instruction manual and did word by word:
- connected phone to Obi with cable provided in box
- connected router to Obi with cable provided in box
- turned it on with power cable, again provided in box

4. Dial **9 222 222 222 - this just connects to obi server where you hear in your own voice what you say, its like confirming that the device is functional.

5. Now, come to Obitalk internet part of configuration. Signed up with newly created gmail id on obitalk.com

6. As soon as I got logged on, it asked me add Obi device or something like that happened.. actually from here on, everything is very user friendly driven - you just FOLLOW the prompts. (If you have ever installed a software on your computer successfully, you should be able to follow what you see on your obitalk dashboard also.)

7. Once your obitalk account discovers the Obi device on the dashboard, just check the mac and serial# on the back of the device.

8. Click confirm and your device is registered and linked with your obitalk online account.

9. Now, come to configuring google voice part of the deal, On the Device Configuration page, see Configure Voice Services. That is where you will click "Service Provider 1" and it will give you the option to add your google voice#. Enter your gmail id and password and hit submit.

10. It will ask you to wait for 2 min. and then hit F5 (refresh)

11. Voila!
