Troubleshoot problems before, during or after H.323 Videoconferences

H.323 Beacon is a tool that can be used to measure, monitor and qualify the performance of an H.323 Videoconference session. It can help an end-user/network engineer/conference-operator, as a debugging tool by providing H.323-protocol specific evidence and other information necessary to troubleshoot H.323 application performance problems in the network and at the host (end-to-end). It uses a distributed client/server architecture. The client actually refers to an end-node and the server can be visualized as a core-node. Testing between end-nodes can be achieved by using a number of core-nodes along a test path. This architecture facilitates the H.323 Beacon to perform end-to-end measurements related to H.323 Videoconferencing sessions.
