I keep the fixed line number of my house because I have not found a cheaper rate, but I do not give the number to anyone and the wireless device is discharged. I get enough spam calls on my cell phone, hahaha. But I agree with your perspective on the need to maintain fixed lines in companies. Its use is very different and grants more control over when to remain available. And it helps to separate work time from free time. I also prefer wired headphones for the same reasons as you, I don't trust the possible consequences of the impact of radiation on our body. Good reflection!
