And don't forget, if you're hooking up a multi-handset cordless phone,
it's the base that worries about getting stuff out to the handset. To the
ATA, it all looks like a single handset.

So, one thing to sort out for yourself is how many extensions do you want
for yourself? Since most homes only have one phone line now, which is to
say, one extension, a simplistic solution is such a cordless phone, an ATA,
and unlimitel. Done.
