I got an email from a service that I used to use on a daily basis but had completely forgotten about: OBItalk. This hardware device allowed free use of Google Voice from a homephone. I think we got it about ten years ago and used it as our primary home voice number for at least five or six years.
After that, our home line fell into disuse. I think the service still worked until we sold our house and moved a few years ago, but nobody was using it. We had all moved our telephony to mobile devices by then.
I remember it being an interesting offer: buy this hardware and you’ll never have to pay a phone bill again. I think it was less than $200 at the time and considering what Verizon charged for a landline, it made complete financial sense. Now that there is no reason not to just talk on your mobile, OBITalk has become an interesting footnote in consumer Internet history.
