Keeps calling with no message. God i hate telemarketers! !

"solar research" group - scam for selling solar panels.

I've never had a single number call my phone as many times per day as this one.  Can someone tell me what app to use so that instead of going to voicemail, it calls in an airstrike on the building making the calls.

No airstrikes, but a call blocker should be reasonable effective.  You might have to block the entire area code.  Occasionally I threaten the Indian and Pakistani callers with an airstrike on their call-center.  Shuts them up fast.  Yeah, I know I shouldn't do it.
