Beschreibung
Zusammenfassung:	A system and method for providing early detection of encrypted signals with in 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 receive r waits for the signalling message for the correct mode of operation. No packets are utilized until the receiver and transmitter encryption capabilities are matched.
