AT&T no more Wireless Home Phone

We still have an actual landline, but it doesn't get used much. Three reason, 1, for the business because it was the number before cellphone days. But the answering machine says to call the business cell phone. 2. 13 year olds call when they get off the bus, and they are to young for cellphones. 3, we have the multi phone cordless phone where only one has to be connected to the phone jack for it to work. Elderly family lives close by, and we want the phone to be heard if something is needed by them as we have 4 cordless phones around the house and don't want them to have to worry about what cell number to call hoping the phone is glued to someones side for them to hear it.

We were looking at transfer to verison home phone just to save the difference, but I am sort of concerned now about moving if it is potentially going to get dropped in the future.
