It's pretty simple. For calling residential numbers for marketing purposes:
1) Subscribe to the federal and state Do-Not-Call lists for each state you're going to call people in. Don't call anyone on those lists unless you have a business relationship with them. It's legal for Comcast to call you to upsell you to a better package if you're a Comcast customer, even if you're on the federal DNC list.
2) Keep a copy of your Do-Not-Call policy on file to provide to callers if they ask for it.
3) If a caller asks to be put on your Do-Not-Call list, do so and don't call them again.
4) Don't spoof your caller ID as anything but your business or the business you're calling on behalf of.
I could've easily missed something, but that's the gist of what I got from reading the federal telemarketing acts. There's also lots of technical details on performance thresholds for predictive dialers and such, so that you don't get too many of those calls where you pick up and nobody is on the other end as the autodialer was too aggressive.
