Call distribution techniques

摘要

Increasing the efficiency of phone call usage is accomplished by using strategic call forwarding techniques to analyze incoming calls and process these calls in real time to: 1) divert unwanted robocallers and/or 2) provide information about unknown human callers. Robocallers are detected by analyzing incoming calls to determine if the audio is human-based or generated by a robocaller. Information about unknown human callers is obtained by real-time look up and reporting techniques to allow the user to determine whether to answer a call.

主权项

1. A method comprising:
intercepting an incoming call placed by a caller to a receiver, wherein the incoming call comprises incoming call data; if a portion of the incoming call data matches a pre-established list of approved callers, forwarding the incoming call to the receiver; determining if the portion of the incoming call data matches a pre-established list of disapproved callers; answering the incoming call while playing a ringback tone to the caller for a preset time period; analyzing incoming call audio during the preset time period to determine if the caller is a human or a machine; if the caller is determined to be a human and the portion of incoming data matches the pre-established list of disapproved callers, terminating the call; if the caller is determined to be a human and the portion of incoming data does not match the pre-established list of disapproved callers, forwarding the incoming call to the receiver; and if the caller is determined to be a machine, forwarding the incoming call to a honeypot server.
