The present invention is generally directed to the field of telecommunications and more particularly, is directed to securing Voice over Internet Protocol (VoIP) wireless and wireline telecommunication traffic.
Legacy telecommunications networks and customer premise equipment transmit and receive analog telephony signals to and from a telephone company's central office switches. While unauthorized interception of telephony traffic over such legacy networks is possible, it most often requires a physical tapping into the transmission lines or compromise of a telephone company's switching stations to accomplish.
With the recent and continued migration of voice telephony traffic from analog switched to packet switched networks, unauthorized interception of the Voice Packets is much easier to accomplish than within the legacy telephone system. Further, as wireless transport layers such as 802.11—so called wi-fi, 802.16—so called WIMAX and 600-800 MHz—so called broadcast white space, become ubiquitous the privacy of a person's VoIP phone calls over such transport layers is further imperiled, by wireless packet sniffers for example which are easily obtained.
Accordingly, there is a need in the art for a more secure method and apparatus for traffic over a packet switched network.
The present invention transforms analog speech signals received from a standard POTS phone into Voice over Internet Protocol Packets. The transformed packets are compressed and encrypts in real time via ASIC and/or SOC firmware. The method and apparatus of the present invention then determines via hardware and software the available and optimal wireless transmission protocols and frequencies within the device's zone of reception and transmits the transformed encrypted voice packets to the available and optimal remote antenna radio.
