SYSTEMS AND METHODS OF ROUTING IP TELEPHONY DATA PACKET COMMUNCIATIONS

摘要

Systems and methods performed by a telephony device allow the telephony device to test the quality of multiple potential paths which can be used to conduct a telephony communication. By testing the conditions that presently exist, the telephony device can choose the path that is presently offering the best quality. A telephony communication may be setup over an initial path, and then subsequent testing may determine that it is best to switch to an alternate path offering better call quality. The initial path used for the telephony communication may be the one that offers the fastest initial connection. When multiple potential paths exist, the telephony communication may be conducted over a first path while keep alive messages are communicated over a second path so that the telephony communication can be quickly switched to the second path.

主权项

1. A method of identifying one or more preferred paths for transmission of digital data packets bearing the media of an Internet protocol (IP) telephony communication that is to be conducted by a telephony device, comprising:
conducting testing to determine the respective quality of each of a plurality of paths that can be used to communicate data packets between the telephony device and one or more elements of a communications network; evaluating the results of the conducting step to determine the relative quality of each of the plurality of paths; and identifying one or more of the paths as preferred paths based on the result of the evaluating step.
