Built in telephone answering devices (TAD) are now commonplace in cordless phones, though if that's not a must, you can save a few dollars by opting for a cordless phone without one. TAD's vary from basic digital answering machines to more sophisticated models with multiple greetings and the ability to alert you to a message while you are away from home, along with options to play it back remotely. Caller ID is, of course, standard, but some models will spare you the effort of getting up to look at a display by announcing the caller with talking caller ID.
Some cordless phones/answerers include a corded phone on the base unit. This is especially handy for prolonged power outages, since corded phones don't need a power source other than the phone line. Other phones have a back-battery that can keep you talking for at least a little while when the lights go out.
