Abstract

A home-link gateway system for providing remote access to contracted telephone services at a home or other physical location is disclosed. The home-link gateway manages communications at the home location, for example between a PSTN or VoIP telephone network and local telephone handsets. A remote client agent requests access to telephone services, via the Internet. Following authorization and registration, the home-link gateway couples the remote client agent to the telephone network, or to local handsets, as though the remote client agent were deployed at the home location.

Claims

1. A home-link gateway for controlling communications within a home, comprising:

a telephone network interface, for coupling to a telephone communications facility for receiving and transmitting telephone communications to a telephone network;

at least one local telephone interface, for coupling to a telephone handset at a location of the home-link gateway;

a wide-area network link, for coupling to a wide area network; and

circuitry for managing telephone communications between a remote client communicating via the wide-area network link and the telephone network, by authenticating the remote client and forwarding communications between the wide-area network link and the telephone network interface.

2. The gateway of claim 1, wherein the telephone network is the Public Switched Telephone Network;

and wherein the telephone network interface comprises a Foreign Exchange Office interface.

3. The gateway of claim 2, wherein the at least one local telephone interface comprises a Foreign Exchange Station interface.

4. The gateway of claim 2, wherein the wide-area network link comprises an Internet Protocol link.

5. The gateway of claim 2, wherein the wide-area network link comprises a broadband modem function.

6. The gateway of claim 1, wherein the telephone network is a Voice over Internet Protocol service;

wherein the wide-area network interface comprises an Internet Protocol link;

and wherein the managing circuitry is also for receiving Internet Protocol communications from the remote client over the Internet Protocol link, and for transmitting corresponding Voice over Internet Protocol communications to the Voice over Internet Protocol service over the Internet Protocol link.

7. The gateway of claim 6, wherein the at least one local telephone interface comprises a local area network interface.

8. The gateway of claim 1, wherein the managing circuitry is also for managing telephone communications between the remote client communicating via the wide-area network link and a telephone handset coupled to one of the at least one local telephone interface.

9. The gateway of claim 1, wherein the managing circuitry comprises:

a programmable processor system, coupled to the wide-area network link;

an FXO/FXS interface function, coupled to the at least one local telephone interface and to the programmable processor system; and

memory for storing program instructions executable by the programmable processor to perform the authenticating and forwarding functions.

10. The gateway of claim 9, further comprising:

at least one local area network interface, coupled to the programmable processor system.

11. A method of providing telephone communication services at a first physical location for a client device at a second physical location remote from the first physical location, comprising the steps of:

receiving a remote access request from the client device over a wide-area network interface;

authorizing the client device for telephone communications;

then receiving a communication from the remote client comprising a destination identifier for a desired telephone call;

forwarding signals to a telephone network requesting placement of a call corresponding to the destination identifier; and

forwarding communications signals between the telephone network and the remote client, over the wide-area network interface, to carry out the telephone communications.

12. The method of claim 11, wherein the telephone network is the Public Switched Telephone Network.

13. The method of claim 12, wherein the wide-area network link comprises an Internet Protocol link;

and wherein the step of forwarding communications signals comprises formatting Voice over Internet Protocol signals into signals suitable for communications over the Public Switched Telephone Network, and vice versa.

14. The method of claim 11, wherein the telephone network is a Voice over Internet Protocol service;

wherein the wide-area network interface comprises an Internet Protocol link;

and wherein the step of forwarding communications signals comprises;

receiving Internet Protocol signals from the remote client over the Internet Protocol link; and

formatting signals into a suitable format for Voice over Internet Protocol communications, over the Internet Protocol link.

15. The method of claim 11, further comprising:

after the authorizing step, registering the remote client as a network element at the first physical location; and

formatting signals received from the registered remote client into a form suitable for a local telephone device at the first physical location, and vice versa.

16. The method of claim 15, wherein the local telephone device comprises a telephone handset suitable for communication over the Public Switched Telephone Network;

and wherein the step of formatting signals formats signals received from the registered remote client into an analog form, and vice versa.

17. The method of claim 15, wherein the local telephone device comprises a Voice over Internet Protocol telephone handset.

and wherein the step of formatting signals formats signals received from the registered remote client into a suitable format for Voice over Internet Protocol communications, and vice versa.

18. The method of claim 11, further comprising:

after the authorizing step, registering the remote client as a network element at the first physical location;

receiving an incoming telephone call from the telephone network; and

forwarding signals corresponding to the incoming telephone call to the registered remote client over the wide-area network interface.

19. The method of claim 11, further comprising:

after the authorizing step, registering the remote client as a network element at the first physical location;

responsive to a request from a local telephone handset, initiating a telephone call with the registered remote client; and

then forwarding communications signals between the local telephone handset and the registered remote client.

20. The method of claim 19, wherein the then forwarding step comprises:

formatting signals received from the registered remote client into an analog form, and vice versa.

21. The method of claim 19, wherein the then forwarding step comprises:

formatting signals received from the registered remote client into a suitable format for Voice over Internet Protocol communications, and vice versa.

22. The method of claim 11, further comprising:

after the authorizing step, registering the remote client as a network element at the first physical location;

storing at least one call-forwarding rule;

comparing at least one attribute of an incoming telephone call from the telephone network to the at least one call-forwarding rule; and

responsive to the comparing step determining that the at least one attribute matches the at least one call-forwarding rule, forwarding signals received from the telephone network to the registered remote client.

23. The method of claim 22, wherein the at least one rule corresponds to a set of at least one telephone number associated with the incoming telephone call.

24. The method of claim 22, wherein the at least one rule corresponds to a time of day of the incoming telephone call.

25. The method of claim 22, wherein the registering step is repeated for a second remote client;

and wherein the step of storing at least one call-forwarding rule is repeated for the second remote client, the rules for each of the remote clients differing from one another.
