Methods and apparatus to provide extended voice over internet protocol (VoIP) services

1. A method, comprising:

facilitating registering, by a system including a processor, a voice over Internet protocol communication device to a voice over Internet protocol service in response to a presence detection of a communication device in an area, wherein the voice over Internet protocol communication device and the communication device are physically separate devices; and

facilitating de-registering, by the system, the voice over Internet protocol communication device from the voice over Internet service in response to an absence detection of the communication device in the area.

2. The method of claim 1 , wherein the communication device provides cellular communication services, the registering of the voice over Internet protocol communication device to the voice over Internet protocol service includes enabling the voice over Internet protocol communication device to communicate utilizing a telephone number associated with the communication device.

3. The method of claim 1 , wherein the presence detection of the communication device is performed by an RF detector.

4. The method of claim 1 , wherein the de-registering of the voice over Internet protocol communication device includes updating a list of barred voice over Internet protocol devices.

5. The method of claim 1 , wherein the de-registering of the voice over Internet protocol communication device includes performing a session initiated protocol de-registration.

6. The method of claim 1 , wherein the communication device and the voice over Internet protocol communication device are associated with a same telephone number.

7. The method of claim 1 , further including disabling a cellular service to the communication device responsive to a determination that the communication device is present in the area.

8. The method of claim 1 , wherein the registering of the voice over Internet protocol communication device to the voice over Internet protocol service includes updating a list of active voice over Internet protocol communication devices.

9. A tangible machine readable storage device comprising instructions that, when executed, cause a processor of a communication device to perform operations comprising:

transmitting a signal from the communication device to enable a system to perform a presence detection of the communication device in an area, wherein a voice over Internet protocol communication device is registered by the system to a voice over Internet protocol service in response to the presence detection of the communication device in the area, wherein the voice over Internet protocol communication device and the communication device are separate devices; and

providing a communication service at the communication device responsive to the communication device being outside of the area, wherein the communication service is disabled at the communication device responsive to a determination by the system that the communication device is present in the area, and wherein the voice over Internet protocol communication device is de-registered from the voice over Internet service in response to an absence detection by the system of the communication device leaving the area.

10. The storage device of claim 9 , wherein the communication device provides cellular communication services, the voice over Internet protocol communication device is registered to the voice over Internet protocol service by enabling the voice over Internet protocol communication device to communicate via a telephone number associated with the communication device.

11. The storage device of claim 9 , wherein the voice over Internet protocol communication device is de-registered from the voice over Internet service by updating a list of barred voice over Internet protocol devices.

12. The storage device of claim 9 , wherein the voice over Internet protocol communication device is de-registered from the voice over Internet service by performing a session initiated protocol de-registration.

13. The storage device of claim 9 , wherein the communication device and the voice over Internet protocol communication device are associated with a same telephone number.

14. The storage device of claim 9 , wherein the system includes a residential gateway.

15. The storage device of claim 9 , wherein the voice over Internet protocol communication device is registered to the voice over Internet protocol service by updating a list of active voice over Internet protocol communication devices.

16. A communication device comprising:

a processor; and

a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, including:

transmitting a signal from the communication device to enable a system to perform a presence detection of the communication device in an area, wherein a voice over Internet protocol communication device is registered by the system to a voice over Internet protocol service in response to the presence detection of the communication device in the area, the voice over Internet protocol communication device and the communication device being separate devices; and

providing a communication service at the communication device responsive to the communication device being outside of the area, the communication service being disabled at the communication device responsive to a determination by the system that the communication device is present in the area, and the voice over Internet protocol communication device being de-registered from the voice over Internet service in response to an absence detection by the system of the communication device leaving the area.

17. The communication device of claim 16 , wherein the communication device provides cellular communication services, and the voice over Internet protocol communication device is registered to the voice over Internet protocol service by enabling the voice over Internet protocol communication device to communicate via a telephone number associated with the communication device.

18. The communication device of claim 16 , wherein the voice over Internet protocol communication device is de-registered from the voice over Internet service by updating a list of barred voice over Internet protocol devices.

19. The communication device of claim 16 , wherein the voice over Internet protocol communication device is de-registered from the voice over Internet service by performing a session initiated protocol de-registration.

20. The communication device of claim 16 , wherein the communication device and the voice over Internet protocol communication device are associated with a same telephone number.
