Obihai and Google Voice for Free Calls in 2016

Obihai is a VoIP company from California that designs and manufactures Analog Telephone Adapters (ATA). These devices turn a regular landline phone into a VoIP phone, and when connected to a VoIP provider, cheap phone calls can be achieved.

To take this one step further, when the Obihai ATA is connected to Google Voice, you can make and receive calls inside the US and Canada free of charge.

Intrigued? If so, read the following article and by the end of it you will be ready to say your goodbyes to all phone bills.

Obihai and Google Voice

Obihai ATAs and How it Works

Obihai makes Analog Telephone Adapters (ATA). An ATA is a device that takes your existing analog telephone and converts your voice to a digital format and sends it over your Internet connection (Cable, DSL, FiOS etc). This technology is referred to as Voice over IP, or simply VoIP, and because the calls are sent over the internet, it is much cheaper than traditional phone service. Figure 1 below shows a typical setup for your home, using the OBi200 as an example.

The actual device is very small, less than 3 inches on each side, and has only 4 connections: power, internet, phone and USB, as seen in Figure 2.

Google Voice

Now to Google voice, why is this required I hear you ask. Well, the Obihai ATA simply provides the hardware and software to make phone calls using your existing telephone, it does not handle the actual routing of phone calls to the PSTN, cell phones or indeed other VoIP lines. For this we need a VoIP service provider.

The Obihai ATA can actually be used with most VoIP service providers, such as the ones you see in the table on the right hand side. These providers each offer low cost phone service with a rich feature set. Google Voice, however, is completely free and enables free phone calls inside the US and Canada along with low cost International calls. It was created by Google as a softphone to allow Google users to make free calls from a computer. Obihai was smart enough to realize that there were other ways to take advantage of this technology and allow users to make calls using traditional analog telephones.

Obihai with Google Voice - What's the Catch?

There really isn't a catch. Sure, you have to buy the Obi ATA device, which costs upwards of $40 for the base model. This is a one time fee, and Google Voice is completely free for calls inside the US and Canada.

However, a few things to realize before you jump in:

  1. There is no official support from Google for this service. Google could tear this service at any time. In fact they nearly did before but decided to keep it going as part of its Google hangouts service.
  2. The feature set is very limited compared to the providers you see on the right hand side.
  3. Support wise, you are on your own. Hopefully this guide will help here though.
  4. Be careful with telephone numbers. If you are looking for a new number with a specific area code you may be out of luck, as there is not a huge selection to choose from. If you wish to port a number into google voice, at the present time this can only be performed with mobile phone numbers and be aware that currently there is a fee of $20 associated with this. You cannot port a landline number into google voice. If you need to port your Google voice number out of google it will cost you $3, at this time of writing.
  5. E911 calling. Google Voice does not support E911 emergency service calling. However, Obihai has a way around this, where you can partner with Anveo, for E911 service. There is a small fee associated with this, currently $15 per year.

Setting up Obihai and Google Voice

The setup for the OBi and Google Voice is not too difficult but there are a few steps that must be followed. First the hardware setup, Figure 3 shows my setup for the OBi200 device I used for this exercise. The only connections required were power to the OBi200, the phone line connection from the analog phone and the Ethernet cable that goes to my Internet router. No connection is needed for the USB, though this can be useful if you require WiFi (separate OBiWiFi adapter required).

Create a Google Voice Account

You will need a Google voice account. To get this you need a Google account (e.g. Gmail) before signing up for a Google voice account and phone number. Navigate to Google voice at http://www.google.com/voice and sign-in and follow the process to get a new phone number. A few verification steps will be required before you are given a new phone number.

Create an OBiTalk Account

Now that Google voice is configured, it is time to sign up for OBiTalk. Register for an account and sign in with Google as it is easier, especially if you have already logged in to Google on your Internet browser.

Add your Device to OBiTalk

After creating an OBiTalk account and then signing in to OBiTalk, it is time to Add a Device. Usually this is the first thing that will appear when you sign in for the first time. You will be presented with some information on how to add a device, as highlighted in Figure 4 below.

Figure 4: Add a Device in OBiTalk

Remember to check the box for configuring Google voice for this device and click on Next. The setup will then give you instructions for the phone, as shown in Figure 5 below. This step is needed to connect the OBi device to the OBiTalk server. Note that the number you see in Figure 5 varies so follow the directions given for your own setup.

Connect to OBiTalk Server

Figure 5: Connect to OBiTalk Server

I had some issues on this step and the OBi device would not connect successfully. I made the phone call and got the automated response but I got an error in OBiTalk. The problem turned out to be the ports that were configured in my router. Certain ports need to be forwarded in your router to the OBi device in order for a successful connection between the device and the Obihai servers. For more details on this, see our OBi200 Review page (Figures 3 and 4 on that page). Once I forwarded the ports in my router, I successfully connected my OBi device to the OBiTalk servers. Review the Emergency Services dialog box and then the Google Voice terms and conditions and then click on the "Finish Setup" button.

Google Voice Configuration

You may need to sign in again to Google Voice with your email and password, from inside OBiTalk, and once you hit the final "Accept" button it will finalize the Google Voice setup. This can take up to 2 minutes, and will look like Figure 6 below while it is configuring. When it is done it will show "Connected" as the status.

The OBi dashboard will now look like Figure 7, indicating that the OBi device is connected to the Obihai servers.

The problem begins with what I just found out about the ObiHai. Obi 100. Activated in Jan of 2015. As soon as support ended, your ability to USE GV ended. You have to pay up to continue to use it. So much for pay once.

Hi, I am in Canada, I've set up Obi200 and can make a call through Google Voice, but I don't receive incoming calls. How do I set up incoming calls?

-> Response: It is likely an issue on your router/firewall. You need to forward ports to get past firewall related issues. More of this can be found on our Obihai review page.

Live in the boonies so DSL speed is capped at 1.5mbs down & 0.250mbs up. Is that sufficient for good communication on the OBi202 ? Thanks

-> Response: I am a little worried about the uplink speed. Technically you only need about 100Kb/s or less for VoIP and you have 250Kb/s so it is possible but you could see some issues if also doing other things on the Internet at the same time.
Have you run our VoIP test yet? I would recommend running it.

Any fee for services, besides purchasing the device? What is the cost for porting my tel number

-> Response: No monthly or yearly fee and calls inside the US/CAN are free (calling outside US/CAN there are charges from 1c/min).
There is a $20 fee to port your number to Google, at this time of writing.
