Audio and video calling through multiple terminal devices

A tangible computer-readable storage device, comprising computer instructions which, when executed by a media processor, cause the processor to perform operations comprising:

• executing a soft-phone client application on the media processor, wherein the soft-phone client application is operable to:
• receive an audio call or a video call originating from an internet protocol multimedia subsystem network, wherein the audio call or video call is directed to the media processor by a gateway having a switching element that routes the audio call or video call;
• selectively answer one of the audio call or the video call at any terminal device registered with the gateway including at the media processor when the media processor is selectively chosen and at a mobile cellular phone coupled to the media processor via a femtocell when the cellular phone is registered with the gateway and selectively chosen;
• and
• present an audio portion of the audio call or of the video call through a speaker of a presentation device operatively coupled to the media processor;
• and
• integrate, via the femtocell, a plurality of wireless carrier services used by a plurality of mobile cellular phones and a plurality of phone numbers to enable audio and video calls at the set-top box using any of the plurality of phone numbers;
• and wherein the gateway receives a notice from the femtocell responsive to the mobile cellular phone establishing communications with the femtocell.

A method at a gateway, comprising:

• receiving a session initiation protocol message corresponding to an audio call or a video call;
• determining from a called number in the session initiation protocol message that the audio call or the video call is directed to a set top box, voice over internet protocol phone or mobile cellular phone coupled to the gateway;
• receiving the audio call or the video call destined for the set-top box, voice over internet protocol phone or mobile cellular phone;
• retrieving from the session initiation protocol message a calling party number;
• transmitting to the set-top box, voice over internet protocol phone or mobile cellular phone a caller identification associated with the calling party number;
• causing a digital switch in the gateway to route the audio call or the video call to the set-top box on the basis of the called number in the session initiation protocol message and responsive to receiving a signal from the set-top box indicating that the audio call or video call has been answered by the set-top box and alternatively routing the audio call or the video call to any of a plurality of terminal devices coupled to the gateway including a mobile cellular phone coupled to the gateway via a femtocell when the mobile cellular phone is selectively chosen;
• integrating, via the femtocell, a plurality of wireless carrier services used by a plurality of mobile cellular phones and a plurality of phone numbers to enable audio and video calls at the set-top box using any of the plurality of phone numbers;
• and
• receiving a notice from the femtocell responsive to the mobile cellular phone establishing communications with the femtocell.
