The core patent-pending VGCP is industry's most state-of-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 disguises 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. VGCP is fully transparent to upper SIP proxy or UA which means VoiceGuard@ can work with any 3rd party softphone/ATA/Gateway/IP Phone/IADs and SIP Proxy or Server not like some competitors which take effect on their own device and softswitch.
