A telecommunications system having a software dispatcher is provided for delivering messages between dispatcher clients, i.e., software subsystems that may be in the same process, a different process, or on a different machine. The dispatcher manages a pool of threads to balance the workload. The dispatcher can process both synchronous and asynchronous messages by dispatching the message to all registered subsystems in order of their registered priority.

During voice-over-Internet-protocol calls, data are gathered about packet loss on the path over the IP network. An algorithm (in the preferred embodiment, the Sliding Window Exponential Average Algorithm) is used to evaluate the packet loss. The Sliding Window Exponential Average Algorithm allows for past performance to be considered along with current performance. If the resulting evaluation fails to meet predetermined criteria, the path over the IP network is blocked and calls are routed over an alternative.
