So, would the button stay on steady or not light at all on hold?

Utilities have a massive infrastructure that has to be developed and maintained. Imagine the amount of money that was invested in exchanges, switches, poles, line, R and D and tons of different things we never considered. It all has to work, or the public is outraged. With the build quality of these great WE phones, I wonder how much they actually cost to make and maintain. Now, that being said, my grandma paid rent on a WE 554 until 2000, which was not exactly upstanding.
