A distributed method of delivering events to agent devices. A first software module generates an event, e.g., a screen pop event or a ringing event, for delivery to a second module responsible for an agent device. A third module, which may be the same module as the first module, evaluates a hash function to determine an identifier for the second module from an identifier for the agent device. The first module delivers the event to the second module, which responds to the event, e.g., by causing an agent device to generate a ringing alert or to display a screen pop.
