Abstract: The disclosed invention enables a user to select a Voice over IP (VOIP) call path to monitor. In particular, a user interface presents data regarding nodes within a VOIP network. The user may select between different possible configurations to monitor, including fully meshed whereby every site including a test probe router is connected to every other site; hub-and-spoke in which a subset of the sites are designated by the user as hubs connected to every other site or spokes connected only to hubs; or a custom configuration in which the user selects which individual call paths to monitor. Embodiments of the present application provide a tool that accepts the user's selections and implements the commands needed to define the desired VOIP network nodes to be monitored, preferably by configuring IP SLA or other tools to provide synthetic data in the selected VOIP call path, and then measuring the performance of the network elements in the selected call path when transferring the synthetic data.
