The PBX at my place of employment takes care of the business calls. Business associates who have my cell phone number are already in my address book so I can identify them when they call, and I answer those. I have a relatively small family, and all of their phone numbers are ALSO in my address book, making caller ID work well for them, too. Unless it's Publisher's Clearinghouse calling me to figure out where to drop off that big check, anybody else is an unwanted call. Whether that's bill collectors, telemarketers, or politicos, if they're not in my book, they can talk to my voicemail. Furthermore, the majority of my interaction with my family members is through text messaging anyway, since those are 'auto-delayed' if I'm busy. If I'm in a meeting, and you call, I won't answer the phone, and if you don't leave a voicemail (the new definition of ghost-knocking - extremely rude) I will NOT call you back. If you text me with 'hey, got a minute' chances are you'll get a response as soon as I'm free. Eventually the bastards will all switch to SMS messaging. I'm already getting those, but again, it's auto-delayed, and I can immediately block the originating number if it's bullshit, so it's a one shot for them. In any case, telemarketing is going the way of the fax machine. It's a relic of a much older age that has reached it's saturation point, and it's just a matter of time before the industry either evolves or dies.
