  • Patent number: 7274684
    Abstract: In a complete network-in-a-box system acting as an enterprise network demarcation point, packets such as voice, video and data packets, are routed over common network connections, such as LAN and WAN. The packets are mapped from a public address field (such as an IP address) and port number to a private address field and port number, the mapping process typically being handled by a NAT (Network Address Translation). The packets are also prioritized, by marking the packets for priority queuing and routing, and configuring the bandwidths of the WAN traffic and the voice traffic to predetermined quantities and configuring the address fields of the voice devices. Simultaneous transmission of the various packets can be limited to predetermined quantities, typically by utilizing a CAC (Client Access Control).

  • Publication number: 20030033418
    Abstract: The invention provides methods and systems using a Media Gateway Control Protocol (MGCP) Application Layer Gateway (ALG) for delivery of VoIP packets to Internet Protocol (IP) phones and to client adapters (CA). The invention provides a customer premises device acting as a proxy between a single Wide Area Network (WAN) Extranet IP address and any number of MGCP client adapters and MGCP phones. To act as a proxy, the MALG parses MGCP signaling packets and opens communications ports as required to deliver VoIP. The MGCP ALG (MALG) registers MGCP phones and identifies required service parameters. The MALG represents all registered MGCP phones to the Extranet via its single public WAN IP address. The MALG is integrated into premises networks via flexible multi-port LAN connections. The MALG can connect to existing premises networks via multiple configuration options. These options are part of the unique MALG capabilities.
