Background
Way back in July of 2007 I signed up for VoIP phone service with Sunrocket. They sent me a telephone adapter, called a “Analog Telephone Adapter” or ATA, which connected to my land-line phone and my internet connection, enabling me to make calls over the internet from any normal phone. I enjoyed the service for about one month before Sunrocket went out of business.
Sunrocket did not ask for their device back. Unfortunately, they had “provisioned” the ATA so that it only worked with Sunrocket’s service. You couldn’t use it anywhere else. Someone developed a solution for unlocking the device, but I lacked some critical knowledge and couldn’t make the solution work for me. So I ended up with a perfectly good piece of hardware that I couldn’t use. I put it on a shelf in the back of my closet, and there it remained for the next 2 years, like Sleeping Beauty waiting for her prince.
. This can also be done with a Wifi capable Blackberry or Windows Mobile device, but since I don’t have either of those, my instructions will focus on the N810. Setting up other devices should be similar- you’ll just have to find the specific client programs yourself, and they may not be free.
