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.
