I will go through the procedure manual to install the OBi 200 and set it up with Google Voice to get free home service. There is currently an issue with the Polycom server that seem to frustrate a lot of new users. This video will cover the issues I encountered and also how it was solved.

In summary.
1. Connect the Ethernet cable from “Internet” Port to your Router. Or the USB
Wifi adapter (optional)
2. Connect the Phone cable from “Phone” to your telephone.
3. Connect the Power adapt to “Power” to your power outlet.
4. Dial **9 222 222 222

IF you can connect successfully to ** 9 222 222 222 then
go to obitalk.com and setup an account. After setting up an obitalk account, it will direct you to dial a **5 ### number. If it did not connect, just keep trying every 15 seconds. Once it timed out, it will give you another number. The customer support says to try after 3:pm PST. I was able to successfully connect after 3:pm PST

IF YOU CANNOT CONNECT SUCCESSFULLY to **9 222 222 222 then
update the firmware then try dialing the **9 222 222 222 again.

Below is the link to the Firmware and some troubleshooting instruction.
