A network telephone device includes a subscriber line/loop interface circuit (SLIC) for coupling to an analog telephone, a telephony processor coupled to the SLIC, and a dial-up modem coupled to the telephony processor. The telephony processor converts outgoing telephone signals from the SLIC into outgoing data packets, and incoming data packets into incoming telephone signals to the SLIC. The dial-up modem converts the outgoing data packets from the telephony processor into outgoing modem signals, and incoming modem signals to the incoming data packets to the telephony processor.
