Systems and methods for detecting call blocking devices or services. The devices monitor outbound call connections to determine if a connected call has been answered by a call blocking device or service rather than a person or answering machine. The verification is a comparison between the connection of an outbound call and a predefined parameter of data associated with that connection. For example, the predefined timing parameter may require detecting a connection before the first ring, or a connection occur within a predetermine period of time from when the outbound call is placed, or a connection occurring after a certain number of rings, etc. Which predefined parameter is associated with a particular outbound call may depend on the call blocking device or service the call center placing the outbound call expects to encounter on a particular connection attempt of a particular phone number. Once the call blocking device or service has been detected on a connected call, the call can be process as if a connection occurred including routing such calls to an available agent or other handling process customized to handle such calls such as automatically navigating prompts for voice or dialing responses from the privacy director systems.
