Abstract
A method for utilizing a household's existing telephone line wiring and existing analog telephone sets to make VoIP calls and PSTN calls is provided. The method allows the installation of a simple VoIP routing device in the existing wiring without restructuring of the existing wiring or a deployment of a totally separate network. The method deploys a number of mapping devices to take advantages of the un-used wires in the existing wiring. The mapping devices are installed between the wall jacks and the phone sets, and between a wall jack and the VoIP routing device. The installation of the mapping devices is easy and requires no special tools and experienced personnel.
