A method, computer program product, and computer system for automatically connecting a calling device to a best available calling device based on resource strength. A computer system receives from a first calling device a request for a call to a second calling device and evaluates resource strength of the second calling device. The computer system determines one or more third calling devices, in response to determining that the resource strength of the second calling device is low. The computer system compares resource strength of the one or more third calling devices with that of the second calling device and determines a best available one of the one or more third calling devices. The computer system connects the call by connecting the first calling device and the best available one of the one or more third calling devices.
