Abstract

Methods and devices for protecting telephone privacy are provided. Privacy is provided by altering the pitch of a person'"'"'s voice, recording the call, changing caller ID information, routing a call straight to voicemail, playing background sounds during the call, call forwarding, and messaging. The various privacy mechanisms can be performed alone, or in combination with certain triggers, such as receiving a call from a certain number, dialing a call to a certain number, transmitting caller ID information with a certain number, or contacting a certain dial-in number of a call handling system.

Claims

1. A method of modifying a telephone call between a local telephone that initiates the call and a remote telephone that receives the call via a call switching system based on a call rule, the method comprising activating a call modification protocol based on a dial-in number called by the local telephone number that is one of a plurality of dial-in numbers of the call switching system;

in which the call modification protocol comprises transmitting the call from the call switching system to the remote telephone with a spoofed number based on the dial-in number called;

in which the spoofed number is selected by comparing at least a portion of the dial-in number to a stored list of dial-in number portions each having an associated spoofed number portion, said associated spoofed number portion selected from the group consisting of;

a country code, an area code, an exchange, and a combination of any of the foregoing;

in which the spoofed number comprises said spoofed number portion and the remainder of the spoofed number is randomly generated; and

in which the dial-in number is not the same as a number of the remote telephone.

2. The method of claim 1, in which the area code of the spoofed number is selected by comparing at least a portion of the dial-in number to a stored list of dial-in number portions each having an associated spoofed number portion that is a spoofed number area code.

3. The method of claim 1, in which the area code and exchange of the spoofed number is selected by comparing at least a portion of the dial-in number to a stored list of dial-in number portions each having an associated spoofed number portion that is a spoofed number area code and exchange.

5. A memory storage device comprising non transitory machine-readable media, said device comprising a program which when read by a computing device causes said device to perform the method of claim 1.

4. A method of modifying a telephone call between a local telephone that initiates the call and a remote telephone that receives the call via a call switching system based on a call rule, the method comprising applying a call rule that includes a call modification protocol, in which the dial-in number is not the same as a number of the remote telephone;

wherein said modification protocol comprises routing the call directly to a voicemail box of the remote telephone, comprising;

initiating a decoy call from the call switching system to the remote telephone;

maintaining the decoy call at least until the remote telephone is designated as busy; and

initiating a second call from the call switching system to the remote telephone after the remote telephone is designated as busy, resulting in the second call being directly forwarded to the voicemail box;

and wherein the call rule is selected from one of the following;

(i) activating a call modification protocol based on a portion of a spoofed number selected to be sent by the local telephone to the remote telephone, or

(ii) activating a call modification protocol based on a dial-in number called by the local telephone number that is one of a plurality of dial-in numbers of the call switching system.
