I use Spectrum (RoadRunner) phone service (as well as Internet and TV) in New York City.;
I called Spectrum and was told that Spectrum is land line because the signal goes completely through cable. Soon after I realized that it couldn't be true that the signal goes completely through the cable because you can call people and get calls from people who don’t have cable.
Is spectrum land line? If so, does it have all the virtues of he old land line systems (like being safer from hacks than are cell phones and working when cell phones don’t?
