Red Wall Phone with Ringer and Network, No Keypad. The K-1500P-D (desk) and K-1500P-W (wall) phones features a standard wall or desk configuration with a built-in ringer. Both are available in two colors: red or ash. The K-1500P-D or K-1500P-W can be used on an analog PABX station port or standard C.O. line to receive calls.
