Cortelco 2554 Mini Wall Telephone, TT, Ivory is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by The Data Master from Wow I remember these things. They coined the phrase "The phone is RINGING". Anyway, they were durable - you drop one of these on the floor and you broke the tile, you drop a phone today and you break the phone. Good old 2554.
