Single-button paging device or phone for the elderly?

[Archer]

Just a thought to go along with the programming on the phone. Find a phone that you can press and hold an number (like for three seconds) and it will dial a number stored in that memory. Then instead of trying to do a bunch of rewiring, just program all of the speed dial button to the same number. As long as she can remember to hold _any_ button down for x amount of time, then it will connect.
