SYSTEMS AND METHODS OF MODIFYING DATA PACKETS USED IN IP TELEPHONY COMMUNICATIONS

摘要

Systems and methods performed by an IP telephony device or an element of an IP telephony system mask the data contained in data packets bearing the media of an IP telephony communication to prevent an Internet service provider from identifying the data packets as carrying the media of an IP telephony communication. The systems and methods can also modify the size of data packets and/or modify the data transfer rate of a stream of data packets bearing the media of an IP telephony communication to prevent an Internet service provider from identifying the stream of data packets as bearing the media of an IP telephony communication.

主权项

1. A method of modifying the size of one or more data packets bearing the media of an IP telephony communication, comprising
receiving one or more data packets bearing the media of an IP telephony communication, the one or more data packets conforming to a standard used for IP telephony communications; and modifying a size of at least one of the received data packets based on a key that has been established for the IP telephony communication in such a manner that a modified data packet does not resemble data packets that conform to the standard used for IP telephony communications.
