Not that I'm against using an app like this by any means, but according to the FCC...
"placing telemarketing calls to wireless phones is - and always has been - illegal in most cases."
It goes on to say that their are rumors going around that they're creating a sort of 411 for wireless, but this is only in an idea stage.
As well, "Wireless phone subscribers have always been able to add their personal wireless phone numbers to the national Do-Not-Call list, either
online, or by calling toll-free to 1-888-382-1222 from the phone number they wish to register. The do-not-call rules require callers that are not exempt from the rules to stop telemarketing calls 30 days after you register a number." I did this a couple years ago and rarely, if ever, receive telemarketing calls on my cell.
Then, there's always a way to file a complaint:
"If you receive an unwanted telemarketing call that you think violates the do-not-call rules, you can file a complaint using an
online complaint form. There is no charge for filing a complaint. You can also file your complaint with the FCC's Consumer Center by calling 1-888-CALL-FCC (1-888-225-5322) voice or 1-888-TELL-FCC (1-888-835-5322) for TTY; or writing to:
Federal Communications Commission
Consumer and Governmental Affairs Bureau
Consumer Inquiries and Complaints Division
445 12th Street, SW
Washington, DC 20554."
With that said, seems like this app will be able to help you block callers that are exempt from the Do Not Call rules.
Still a great video though. I feel like it'd be easy to start using the app if I found myself in need of it after watching and I'm glad you mentioned things like dropping a current call if a blocked call comes in, because that's good to know from the start.
