the panasonic has a phone jack. same one as my nokia cell phone. the panasonics we have (two different models) talk to each other, have a 50 or so blocker feature, and work from the end of the pier to our house(some 300 feet). the only feature i would like would be to be able to upload and down load a phone directory from a pc. i once saw one of those. think it on a Vtech.
we have had decent reliability on vtech, panasonic, uniden. not good on att.
