To amplify what Jason said about the additional points of failure. I look at the fire alarm systems we have in place. The standard for fire panels now is cellular with a phone line as the backup. That way if you have a cable cut down line it does not immediately send you into fire watch, which comes with all the over time involved, before the repair can be made.
I wonder if there is a similar option for emergency phones.
