VGCP (Voice Guard@ Control Protocol) is our core technology for VoIP anti-blocking solutions. It is a proprietary layer 2 link protocol working at between IP stack and NIC driver. The core patent-pending VGCP is industry’s most state-of-the-art voice service provider class security protocol whose scalability and flexibility results in not to compromise voice quality and overhead. VGCP controls and monitors full voice signaling and media flow intelligently, meanwhile disguise SIP and RTP packets into normal allowed data packets such as DNS and TFTP, and makes two-way encryption and decryption driven by user-customized policy. Even in some circumstance, VGCP can simulate traffic behavior of universal data networking protocol such as OICQ, MSN and so on.
