Systems and methods of routing IP telephony data packet communications
First Claim
1. A method of routing a Voice over Internet Protocol communication, comprising:
- receiving, at an originating user telephony device, a request to setup a communications channel between the originating user telephony device and a destination telephony device;
establishing the requested communications channel over an initial media path;
testing, via the originating user telephony device, a quality of the initial media path on a periodic basis after the communications channel has been established;
determining a communications quality of the initial media path after each occurrence of the periodic testing; and
causing the communications channel to switch from the initial media path to an alternate media path when the communications quality of the initial media path is lower than a predetermined threshold quality level, wherein the causing step comprises;
testing, via the originating user telephony device, a quality of one or more alternate media paths for the communications channel;
determining when the communications quality of at least one of the one or more alternate media paths is higher than the communications quality of the initial media path; and
switching the communications channel from the initial media path to one of the one or more alternate media paths that has a quality higher than the initial media path when the communications quality of at least one of the one or more alternate media paths is higher than the communications quality of the initial media path.

Abstract
Systems and methods of selecting a media path for data packets bearing the media of a telephone call to traverse during a voice over Internet protocol telephone call include testing the call quality of multiple potential media paths immediately before a call is setup. The potential media path with the highest call quality is used as the initial media path for the call. If the call quality of the media path currently in use declines below a threshold value during a call, potential alternate media paths are identified and tested for call quality. If one of the alternate media paths has better call quality than the media path presently in use, the call is switched to the alternate media path with the highest call quality.

receiving, at an originating user telephony device, a request to setup a communications channel between the originating user telephony device and a destination telephony device; establishing the requested communications channel over an initial media path testing, via the originating user telephony device, a quality of the initial media path on a periodic basis after the communications channel has been established; determining a communications quality of the initial media path after each occurrence of the periodic testing; and causing the communications channel to switch from the initial media path to an alternate media path when the communications quality of the initial media path is lower than a predetermined threshold quality level, wherein the causing step comprises; testing, via the originating user telephony device, a quality of one or more alternate media paths for the communications channel; determining when the communications quality of at least one of the one or more alternate media paths is higher than the communications quality of the initial media path; and switching the communications channel from the initial media path to one of the one or more alternate media paths that has a higher quality than the initial media path when the communications quality of at least one of the one or more alternate media paths is higher than the communications quality of the initial media path. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
