We got rid of the home phone the instant we got a web/cell-based security system for our home (Vivint). The only people that ever called the home phone were telemarketers anyway. Interestingly, we cut the lines outside and removed the Securtek panel when the Vivint was installed and when we cancelled our Securtek security system 3 weeks after the Vivint install, Securtek had not called us to inform us that there was no signal. They had no idea.
EDIT: Wow, 700 pages of random thoughts!
