Patent ID: 10778841

Abstract:
Novel tools and techniques are provided for implementing telephone solicitation prevention using enhanced voice over Internet protocol (“VoIP”) functionalities in conjunction with STIR/SHAKEN protocols. In various embodiments, in response to receiving a call setup message or a call request from a calling party, a call server might send a verification request to a secure telephone identity (“STI”) verification server (“VS”). The STI-VS might verify and send the call setup message to a no solicitation application server, which might instruct a media server to connect to a first gateway device and to play a no solicitation message requesting a response from the calling party, and which might verify whether the response is an appropriate response. If so, a call is established. If not, the call might be disconnected and/or forwarded to a voicemail server to play a voicemail message to the calling party in accordance with preferences of the called party.
