Abstract
Abstract Call routing is controlled by a central unit providing switching control signals based on selecting the best figure-of-merit value from among poll responses for agents. While an incoming call is held by a public network 12 , poll inquiries are sent from a central unit 20 . Each local unit 24, 26, 28 provides a poll response indicative of the one its associated response resources (e.g., agents 31, 32, 33 ) having the shortest queue wait. Each poll response may be a simple figure-of-merit value representing agent availability. Central unit 20 selects the poll response represented by the best figure-of-merit value and sends routing instructions to the network 12 . The call is then routed to the appropriate agent for handling. Where a local unit has no associated agent who is qualified to respond to a call (based on caller data related to that call) no poll response need be sent to central unit 20 . The simplified processing provided enables system operation with reduced data collection and intra-system communication requirements.
