Abstract: A telephone call routing system routes a telephone call from a caller to a mobile resource which is local to the caller and available. Specifically, the mobile resource may be a taxi, such that a customer can “hail” a taxi, without being in the direct line of sight of a taxi driver. An automatic coordinator manages the mobile resources and callers to a call centre and can automatically allocate available and nearby mobile resources to a caller, so that conversation between the caller and an operator of the mobile resource helps direct the mobile resource to the caller.
