Salvage the landline phone infrastructure

With the rise of cell phones, internet communication, and Voice Over IP, landline telephones are quickly becoming obsolete. However, because of decades of landline use, an extensive infrastructure has been left that is not serving its original purpose. 17.1% of Americans have already tossed their landlines, and that number will increase by 3-4% each year.
