Abstract

A method for utilizing a household'"'"'s existing telephone line wiring and existing analog telephone sets to make VoIP calls and PSTN calls are 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.

Claims

1. A method for connecting a routing device in an existing wiring laid out between a first communication network and a client device, said existing wiring comprising at least four electrically conductive wires numbered from 2 to 5, said client device and said first communication network connected with each other via wires 3 and 4 of said existing wiring, said client device capable of making voice calls to and receiving voice calls from said first communication network, said routing device comprising a FXS port, a FXO port, and a communication port, said routing device capable of routing voice calls received from said FXS port to said first communication network via said FXO port and to a second communication network via said communication port, said method comprising the steps of:

providing a first mapping device and a second mapping device; and

connecting said first mapping device to said existing wiring and to said client device so that said client device is connected to wires 2 and 5 of said existing wiring, and connecting said second mapping device to said existing wiring and to said routing device so that said FXS port of said routing device is connected to wires 2 and 5 of said existing wiring and said FXO port of said routing device is connected to wires 3 and 4 of said existing wiring.

2. The method as claimed in claim 1, wherein said first communication network is a public switched telephone network.

3. The method as claimed in claim 1, wherein said second communication network is one of a data network and a public switched telephone network.

4. The method as claimed in claim 1, wherein said client device is a one of a wired telephone set, a cordless phone, a fax machine, an answering machine, and a modem.

5. The method as claimed in claim 1, wherein said routing device is a VoIP routing device capable of routing a voice call received from said FXS port to PSTN via said FXO port and to Internet via said communication port based on an instruction of a user of said client device issuing said voice call.

6. The method as claimed in claim 1, wherein said routing device is a device capable of routing a voice call received from said FXS port to a PSTN via said FXO port and to another PSTN via said communication port based on a destination number of said voice call.

7. The method as claimed in claim 1, wherein said first mapping device is a cable comprising a plurality of electrically conductive wires and a connector at each end, said connector has pins numbered from 2 to 5, said pins connect to identically numbered wires in said existing wiring when said connector is connected to said existing wiring, said wires are arranged so that pins 3, 4 in one connector are connected to pins 2, 5 in another connector.

8. The method as claimed in claim 1, wherein said first mapping device is a cable comprising a plurality of electrically conductive wires, a connector at one end, and a socket on the other end, said connector and said socket have pins numbered from 2 to 5, said connector'"'"'s pins connect to identically numbered wires in said existing wiring when said connector is connected to said existing wiring, said socket'"'"'s pins connect to identically numbered wires in said existing wiring when said socket is connected to said existing wiring via a straight cable, said wires are arranged so that pins 2, 5 in said connector are connected to pins 3, 4 in said socket.

9. The method as claimed in claim 1, wherein said first mapping device is a coupler comprising a plurality of electrically conductive wires and a socket at each end, said socket has pins numbered from 2 to 5, said pins connect to identically numbered wires in said existing wiring when said socket is connected to said existing wiring via a straight cable, said wires are arranged so that pins 3, 4 in one socket are connected to pins 2, 5 in another socket.

10. The method as claimed in claim 1, wherein said first mapping device is a cable comprising a plurality of electrically conductive wires, a connector on one end, and two sockets on the other end, said connector and said sockets have pins numbered from 2 to 5, said connector'"'"'s pins connect to identically numbered wires in said existing wiring when said connector is connected to said existing wiring, each of said sockets'"'"' pins connect to identically numbered wires in said existing wiring when each of said sockets is connected to said existing wiring via a straight cable, said wires are arranged so that pins 3, 4 in said connector are connected to pins 3, 4 in one socket, said wires are arranged so that pins 2, 5 in said connector are connected to pins 3, 4 in another socket.

11. The method as claimed in claim 1, wherein said second mapping device is a cable comprising a plurality of electrically conductive wires, a connector on one end, and two sockets on the other end, said connector and said sockets have pins numbered from 2 to 5, said connector'"'"'s pins connect to identically numbered wires in said existing wiring when said connector is connected to said existing wiring, each of said sockets'"'"' pins connect to identically numbered wires in said existing wiring when each of said sockets is connected to said existing wiring via a straight cable, said wires are arranged so that pins 3, 4 in said connector are connected to pins 3, 4 in one socket, said wires are arranged so that pins 2, 5 in said connector are connected to pins 3, 4 in another socket.
