Abstract

A call jump establishes a jump from a call of a traditional telephone carrier established with audio signals. When it is determined that video should be added to the call, a packetized network is connected. The audio and video are transmitted over the packetized network. There is provided standard telephone equipment. A video enabled device is capable of rerouting the audio selectively to either the traditional telephone carrier or the packetized network. A packetizer packetizes the audio signals from the standard telephone equipment and the video.

Claims

1. A method for performing a call jump from a call established using a Public Switched Telephone Network (PSTN) to a video carrying call, comprising:

establishing a PSTN call with audio signals between a first and second party;

storing a destination number by a video enabled device;

activating the call jump by operation of a device by the first party;

sending a request to complete the call jump in response to the activating;

accepting the call jump by the second party;

generating a signal in response to the acceptance that indicates that the call jump should be completed;

initiating the call jump thereby connecting the parties via a packetized network;

transmitting multiplexed audio and video signals over the packetized network; and

terminating the PSTN call from the Public Switched Telephone Network to proceed with the video carrying call.

2. The method according to claim 1, wherein the device is a telephone or an apparatus coupled to a telephone.

3. The method according to claim 2, further comprising packetizing the audio and video signals.

4. The method according to claim 3, further comprising registering the video enabled device with the packetized network.

5. The method according to claim 3, wherein the activating is achieved via a Dual Tone Multi Frequency key on the telephone.

6. The method according to claim 3, further comprising charging the first party for activating the call jump.

7. The method according to claim 3, further comprising recognizing the established call by the video enabled device.

8. The method according to claim 3, further comprising determining a division between audio and video bandwidth by multiplexing the video signals with the audio signals.

9. The method according to claim 8, further comprising recognizing that video is to be added to the call.

10. The method according to claim 8, further comprising establishing a connection via the video enabled device.

11. A call jump system for jumping a call established over a Public Switched Telephone Network (PSTN) to a packetized network, comprising:

a telephone;

a PSTN call including a first call side and a second call side;

a video enabled device configured to store a destination number;

an input by a user of the first call side that activates the call jump at a first party;

a requestor that requests a second party side to complete the call jump;

an acceptor that accepts the call jump by the second party side;

the video enabled device being configured to reroute the audio selectively to a network system selected from a group consisting of a traditional telephone carrier and the packetized network;

a multiplexor that multiplexes the audio and video;

a packetizer that packetizes the multiplexed audio and video signals from the standard telephone equipment, wherein the video is sent over the packetized network when the call jump is requested by the first party and accepted by the second party; and

the system being configured to terminate the PSTN call from the Public Switched Telephone Network to proceed with the call over the packetized network.

12. The system according to claim 11, further comprising a gateway for coupling the packetized audio and video signals to the network system.

13. The system according to claim 12, wherein the video enabled device is selected from the group consisting of a set top box, a video phone, and a video enabled PC.

14. The system according to claim 12, further comprising a router for routing the audio and video packetized signals through the packetized network to the receiving side.

15. The system according to claim 14, wherein the packetized network is an IP network.

16. The method according to claim 11, wherein the input is via a Dual Tone Multi Frequency key on the telephone.

17. The method according to claim 11, further comprising charging the first party for activating the call jump.
