Abstract

A monitoring device monitors headers of packets on a communications session with a primary communications device, and when it detects packets of a medium that is incompatible with the primary device, it causes those packets to be diverted to a secondary device that is associated with the primary device and that is compatible with that medium. During set-up of the communications session, the monitoring device replaces or supplements the handshake of the primary device, thereby providing to the network a single handshake that identifies the media supported by the combination of the primary and secondary devices.

Claims

1. A method comprising:

during set-up of a communications session with a first communication device that is able to communicate via communications having a first characteristic but is unable to communicate via communications having a second characteristic different from the first characteristic, substituting an indication of ability to communicate via communications having the first characteristic and via communications having the second characteristic for an indication by the first device of ability to communicate via communications having the first characteristic but not the second characteristic;

monitoring the communications session established for communicating in a first medium with the first device;

detecting in the communications session a communication directed to the first device and having the second characteristic; and

in response to the detecting, diverting the communication directed to the first device and having the second characteristic from the first device to a second communication device that is associated with the first communication device and that is able to communicate via the communications having the second characteristic.

2. The method of claim 1 wherein:

indicating comprises during set-up of the communications session, forbearing from negotiating at least the first characteristic for the communications session.

3. The method of claim 1 wherein:

detecting in the communications session a communication having the second characteristic comprises

detecting in the communications session a communication in a second medium different from the first medium; and

diverting the communication having the second characteristic comprises

diverting the communication in the second medium to the second device.

4. The method of claim 3 wherein:

the first medium is compatible with the first device; and

the second medium is incompatible with the first device and compatible with the second device.

5. The method of claim 3 wherein:

monitoring communications session established for communicating in a first medium with the first device comprises

monitoring the communications session for communications in the second medium.

6. The method of claim 1 further comprising:

the first device engaging in the communications session in communications having the first characteristics;

detecting in the communications session a communication having a second characteristic comprises

during the engaging, detecting the communication having the second characteristic; and

diverting the communication having the second characteristic comprises

diverting the communication having the second characteristic while the first device continues to engage in the communications having the first characteristic.

7. The method of claim 1 wherein:

diverting the communication having the second characteristic comprises

monitoring packets carrying communications to the first device; and

diverting packets carrying communications having the second characteristic.

8. The method of claim 7 wherein:

monitoring packets carrying communications to the first device comprises

monitoring headers of the packets for packet type, and

sending packets of a type that carries communications of a first medium to the first device; and

diverting packets carrying communications having the second characteristic comprises

sending packets of a type that carries communications of a second medium different from the first medium to the second device instead of to the first device.

9. The method of claim 1 further comprising:

rendering the communications having the first characteristic on the first device; and

rendering the communications having the second characteristic on the second device.

10. A non-transitory computer-readable medium containing instructions which, when executed by a computer, cause the computer to perform the method of claim 1.

11. An apparatus comprising:

a device for substituting, during set-up of a communications session with a first communication device that is able to communicate via communications having a first characteristic but is unable to communicate via communications having a second characteristic different from the first characteristic, an indication of ability to communicate via communications having the first characteristic and via communications having the second characteristic for an indication by the first device of ability to communicate via communications having the first characteristic but not the second characteristic, for monitoring the communications session established for communicating in a first medium with the first device, for detecting in the communications session a communication directed to the first device and having the second characteristic, and for diverting, in response to the detecting, the communication directed to the first device and having the second characteristic from the first device to a second communication device that is associated with the first communication device and that is able to communicate via the communications having the second characteristic.

12. The apparatus of claim 11 wherein:

the first communication device is for forbearing negotiating at least the first characteristic for the communications session during set-up of the communications session.

13. The apparatus of claim 11 wherein:

the device for indicating, detecting, and diverting is for signaling detection of the communication having the second characteristic; and

the apparatus further comprises

a device responsive to the signaling for routing the communications having the second characteristic to the second device.

14. The apparatus of claim 13 wherein:

the routing device is for sending communications having the first characteristic to the first device via a first communication link, and for sending communications having the second characteristic to the second device via a second communications link different from the first communications link.

15. The apparatus of claim 13 wherein:

the routing device is for sending communications having the first characteristic to a first address of the first communication device, and for sending communications having the second characteristic to a second address of the second communication device different from the first address.

16. The apparatus of claim 11 wherein:

the communications having a first characteristic comprise communications in a first medium; and

the communications having a second characteristic comprise communications in a second medium different from the first medium.

17. The apparatus of claim 16 wherein:

the first medium comprises audio; and

the second medium comprises at least one of text and image.

18. The apparatus of claim 16 wherein:

the first medium is compatible with the first device; and

the second medium is incompatible with the first device and compatible with the second device.

19. The apparatus of claim 16 wherein:
