System and method for handling unwanted telephone calls

A system for handling unwanted telephone calls, comprising:

• at least one processor configured to:
• intercept a call request for a call from a terminal device of a calling party to a terminal device of a called party;
• generate a call recording containing media data transmitted within a connection established by the intercepted call request, wherein the call recording is generated over a specified time interval at which a size of the media data is a multiple of a preset value;
• determine attributes of the generated call recording;
• classify the call as an unwanted call based on the determined attributes, wherein the classification is performed by a classifier trained on previously collected unwanted calls, and wherein the call is classified as unwanted when the attributes belong to an unwanted call class that is known;
• and
• handle the call in accordance with the classification of the call, the handling including at least securing information of the call.

A non-transitory computer readable medium storing thereon computer executable instructions for handling unwanted telephone calls, including instructions for:

• intercepting a call request for a call from a terminal device of a calling party to a terminal device of a called party;
• generating a call recording containing media data transmitted within a connection established by the intercepted call request, wherein the call recording is generated over a specified time interval at which a size of the media data is a multiple of a preset value;
• determining attributes of the generated call recording;
• classifying the call as an unwanted call based on the determined attributes, wherein the classification is performed by a classifier trained on previously collected unwanted calls, and wherein the call is classified as unwanted when the attributes belong to an unwanted call class that is known;
• and
• handling the call in accordance with the classification of the call, the handling including at least securing information of the call.
