We have to have a landline because we are in a cell signal dead zone. There are certain places outside I sometimes get a signal, but it's spotty until you go a few hundred feet up the road. That, and it's needed for our DSL internet, which is the only option here. Either the caller ID is getting smarter or the scammers are getting more honest about what they do. Some recent scam calls actually come up as "SCAM?" on the caller ID. Those, I never even think about answering because they have only happen once in a great while.
