Early detection system and method for encrypted signals within packet networks

A system and method for providing early detection of encrypted signals within a secure connection for voice over Internet protocol (VoIP). The system and method includes a non-complex, in-band, and early encryption detector within the voice path. A transmitter sends out a known pattern. Based upon t...

description A system and method for providing early detection of encrypted signals within a secure connection for voice over Internet protocol (VoIP). The system and method includes a non-complex, in-band, and early encryption detector within the voice path. A transmitter sends out a known pattern. Based upon the received pattern, the receiver decides whether its encryption capabilities match up with those of the transmitter. If the capabilities do not match, then the receiver waits for the signalling message for the correct mode of operation. No packets are utilized until the receiver and transmitter encryption capabilities are matched.
