Back-to back H.323 proxy gatekeeper

A system, comprising:

• a gatekeeper;
• and
• a proxy gatekeeper transparently coupled between the gatekeeper and a plurality of endpoints, the proxy gatekeeper including a first set of ports that represent one or more ports of the gatekeeper to the plurality of end-points and a second set of ports that represent ports of the plurality of end-points to the gatekeeper,
• wherein the proxy gatekeeper is configured to:
• receive a H.323 registration request (RRQ) initiated from an end-point of the plurality of end-points at a port of the first set of ports, wherein the H.323 registration request (RRQ) is addressed to a port of the one or more ports of the gatekeeper,
• store information provided with the H.323 registration request (RRQ) in a storage device associated with the proxy gatekeeper and to send the H.323 registration request (RRQ) to the port of the one or more ports of the gatekeeper,
• sending a non-standard message (NSM) request in response to receiving an H.323 admission request (ARQ) initiated from an end-point at the port of the first set of ports of the proxy gatekeeper, and
• receiving a NSM response.

• store information provided with the H.323 registration request (RRQ) in the storage device and to send the H.323 registration request (RRQ) to the port of the one or more ports of the gatekeeper,
• sending a non-standard message (NSM) In response to receiving an H.323 admission request (ARQ) initiated from an end-point at the port of the first set of ports of the proxy, gatekeeper, and
• receiving a NSM response.

A proxy gatekeeper operable in a system including a gatekeeper and a plurality of end-points, wherein the proxy gatekeeper is transparently coupled between the gatekeeper and the plurality of end-points, the proxy gatekeeper comprising:

• a computing device;
• and
• a memory having stored thereon computer-executable instructions execution of which by the computing device causes the computing device to perform operations including:
• creating a first set of ports and a second set of ports, wherein the first set of ports represents one or more ports of the gatekeeper to the plurality of end-points and the second set of ports represents ports of the plurality of end-points to the gatekeeper;
• receiving a H.323 registration request (RRQ) initiated from an end-point of the plurality of end-points at a port of the first set of ports of the proxy gatekeeper, wherein the H.323 registration request (RRQ) is addressed to a port of the one or more ports of the gatekeeper;
• storing information provided with the H.323 registration request (RRQ) in an endpoint registration storage of the proxy gatekeeper;
• sending the H.323 registration request (RRQ) to the port of the gatekeeper;
• sending a non-standard message (NSM) request in response to receiving an H.323 admission request (ARQ) initiated from an end-point at he port of the first set of ports of the proxy gatekeeper;
• and
• receiving a NSM response.

A non-transitory machine-readable medium having stored thereon instructions execution of which by a computing device serving as a proxy gateway transparently coupled between a gatekeeper and a plurality of end-points causes the computing device to perform operations comprising:

• creating a first set of ports and a second set of ports on the proxy gateway, wherein the first set of ports represents one or more ports of the gatekeeper to the plurality of end-points and the second set of ports represents ports of the plurality of end-points to the gatekeeper;
• receiving a H.323 registration request (RRQ) initiated from an end-point of the plurality of end-points at a port of the first set of ports of the proxy gatekeeper, wherein the H.323 registration request (RRQ) is addressed to a port of the one or more ports of the gatekeeper;
• storing information provided with the H.323 registration request (RRQ) in an end-point registration storage of the proxy gatekeeper;
• sending the H.323 registration request (RRQ) to the port of the gatekeeper;
• sending a non-standard message (NSM) request in response to receiving an H.323 admission request (ARQ) initiated from an end-point at the sort of the first set of ports of the proxy gatekeeper;
• and
• receiving a NSM response.
