Could You Lose the Landline?

When we moved to Texas, we debated on whether or not we even needed a landline. But because I was pregnant at the time, we decided better safe than sorry and got one with the least expensive plan. But as I looked at all the ways we use our phone that I hadn't even considered, I realized that we made the right decision:
-Security Alarm: we use Brinks security and it uses our phone line to connect to the security center.
-TiVo: at least the first TiVo connection needs to be through the phone system.
-DirecTV: needs to connect to the system through the phone.

So before you lose the landline make sure you check out all the things your phone is doing for you behind the scenes!
