This is my method, too. The only problem I have is that it seems about half the companies who cold call sales leads use some software that spoofs a local exchange, and I do generally answer the phone -- even when it's not one of my known contacts -- when it originates from my home area code. Not doing so risks missing calls from contractors, schools, kids' friends, my friends, etc.
