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.
Claims11
A method of connecting a routing device in an existing wiring laid out between a first communication network and a client device for voice calls of said client device using said first communication network or a second communication network, comprising the steps of:
- preparing at least four electrically conductive wires designated as wires 2, 3, 4 and 5 respectively in said exiting wiring;
- connecting said first communication network to said wires 3 and 4;
- connecting a first mapping device to at least said wires 2 and 5;
- connecting said client device to said first mapping device which routes said client device to said wires 2 and 5;
- connecting a second mapping device to at least said wires 2, 3, 4 and 5;
- providing a foreign exchange subscriber (FXS) port, a foreign exchange office (FXO) port and a communication port for said routing device;
- connecting said routing device to said second mapping device which routes said FXS port to said wires 2 and 5, and routes said FXO port to said wires 3 and 4;
- and
- connecting said second communication network to said communication port;
- wherein said routing device connects said FXS port to said communication port for voice calls of said client device using said communication network if said client device sends a pre-defined signal to said routing device, and connects said FXS port to said FXO port for voice calls of said client device using said communication network if said client device does not send said pre-defined signal.
