Abstract
A method and system for secure Voice over Internet Protocol (IP) (VoIP) communications. The method and system provide secure VoIP voice calls, video, Instant Messaging (IM), Short Message Services (SMS), or Peer-to-Peer (P2P) communications while maintaining privacy over the Internet and other communications networks such as the pubic switched telephone network (PSTN) to and from any network device through a virtual private network infrastructure interconnecting private VoIP network devices. The method and system allow a network device to function as an IP private branch exchange (PBX) or a private VoIP gateway and provide and control VoIP voice communications without using other public or private VoIP gateways or VoIP servers or devices on a communications network such as the PSTN or the Internet.
