Abstract: 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.

Abstract: 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.

Abstract: A server computer coupled to a CTI capable telephone or a Teleworking Server coupled to a PBX is also coupled to a wireless gateway/router and is provided with communications software. A personal digital assistant with wireless capabilities or a cell phone with computing capabilities is provided with corresponding communications software for communicating via the wireless network with the server. The server monitors one or more phone numbers associated with each client. When a call comes in, the server immediately notifies the client. The client can direct the server to transfer the call to a nearby phone. This can be accomplished by parking the call in a system slot and by retrieving the call with a nearby desk phone, thus not needing to know the number of the desk phone. Otherwise, the client can have the call forwarded to another telephone number. The client can also redirect the call to voicemail or a personal messaging system.
