US Patent 9288319 Call management system

Systems and methods for deploying and implementing an intelligent call screening and handling system are described. Rather than relying on inline solutions or proprietary interconnects at the carrier level as is the case in the prior art, one aspect of the claimed invention is to use existing functionalities of PSTN infrastructure including for instance simultaneous ring and call forwarding to create a call screening and handling system that is simple to deploy and substantially transparent to the user.
