Abstract

Network architectures, methods, and operations for routing telephone calls are disclosed. A customer premise includes a conventional POTS dedicated communication line to a central office switch and a broadband connection to a data network. The central office switch and the data network are connected by a communication link. An incoming telephone call to the customer premise may be routed by the central office switch for completion to the customer premise via the broadband data network.

Claims

1. A method of connecting a POTS telephone call over a data network, comprising:

receiving, at a gateway in the data network, a signal from a telephone network, wherein the signal includes a telephone number of a primary telephone associated with a voice connection in the telephone network;

in response to the signal, establishing a data connection between the gateway and at least one secondary telephone associated with the telephone number; and

transmitting a ring signal to the at least one secondary telephone over the data network.

2. The method of claim 1, wherein the signal comprises a status flag indicating the availability of the voice connection.

3. The method of claim 1, wherein the signal is transmitted to the gateway from a central office switch.

4. The method of claim 1, wherein the signal is associated with an incoming telephone call.

5. The method of claim 1, wherein establishing a data connection between the gateway and at least one secondary telephone associated with the telephone number comprises determining whether at least one secondary telephone associated with the telephone number is available.

6. The method of claim 1, wherein routing the POTS telephone call to the at least one secondary telephone over the data network comprises routing the call to a connection point associated with the telephone number.

7. The method of claim 6, wherein the connection point comprises a DSL modem connected that maintains a connection to the data network and to the voice connection.

8. The method of claim 6, wherein the connection point comprises a cable modem connected that maintains a connection to a cable network and to the voice connection.

9. The method of claim 1, further comprising:

receiving, from the at least one secondary telephone, a signal indicating that the at least one secondary telephone changed form an on-hook state to an off-hook state; and

in response to the change in state, connecting the call to the at least one secondary telephone.

10. The method of claim 9, further comprising recording the change in state of the at least one secondary telephone in a memory location associated with the data network.

11. The method of claim 9, further comprising transmitting a signal indicating that the at least one secondary telephone changed form an on-hook state to an off-hook state to the telephone network.

12. The method of claim 9, further comprising:

receiving, from the at least one secondary telephone, a signal indicating that the at least one secondary telephone changed form an off-hook state to an on-hook state; and

in response to the change in state, terminating the data connection between the gateway and at least one secondary telephone associated with the telephone number.

13. The method of claim 12, further comprising recording the change in state of the at least one secondary telephone in a memory location associated with the data network.

14. The method of claim 12, further comprising transmitting a signal indicating that the at least one secondary telephone changed form an off-hook state to an on-hook state to the telephone network.
