Barbara wants to get a cordless landline phone. Leo says he likes Panasonic, and says that Barbara should make sure that whatever model she gets, it come equipped with DECT (Digital Enhanced Cordless Telecommunciations). Leo also says she can get them to also answer the cellphone number while she's at home.
Leo says it's still important to have a regular phone with a landline through an actual phone company (not a cable provider) for emergencies. That way, if the power goes out, there's still a phone that would work from the power provided through the phone jack.
