Cellphones and Audio (was Ghost Click, though I got no idea why)

As one involved in emergency services I don't gave a rats whether you
can't tell one voice from another. I do care if someone who is having a
fire, accident, cardiac episode or stroke can get through.
The cell companies are worrying about your whim and not the safety.

I have had more than a few surreal conversations on the phone with my
daughter - once the 3.4kHz filter gets done, I can't distinguish her
her mom's (and yes, I've gotten social-engineered as a result). Life
gotten simpler since she got old enough to have her own cell phone. ;)
