Phone Calls
Spam and Scam Calls
Every day, telemarketers and scammers bombard us with phone calls. Not only are these calls annoying, they have costed Americans an estimated 8.9 billion dollars.
Number Databases
In response, some firms have composed databases of spam and scam phone numbers. However, these databases are ineffective due to a technique known as caller ID spoofing. Scammers and Spammers mask their own phone number.
Answering Bots
Others have created bots to answer and vet phone calls before forwarding them to the user. These applications, however, can lead to an increase of spam calls, as users who answer calls receive more in the future.
