[Q] Cell phone 2 home service, does such a thing exist? topic

I am looking for an app/adapter that would allow you to power your wired home phone system using your cell phone. Ideally, I'd like to be able to use a cable, like the one shown, to simply plug my cell phone into one of the home phone jacks to provide service to the wired phones etc. I'm hoping to find a carrier neutral solution. Do you know of anything like this?

Thank you for your time and consideration.
