IRS SCAM!! Received 5 calls in 3 days coming from 3 different phone numbers but same message. Robo voice (sounds just like Siri!) IRS filing lawsuit against me and I must call this number. I am so sick and tired of this nonsense that nobody seems to be able to stop. My landline is being held hostage on a daily basis from this scam, Microsoft Windows, fake charities, etc. They use threats. They frighten people. They can barely speak English. These guys are terrorists in my mind. If I give up my landline I will need to give out my cell phone number and that's not happening. One phone held hostage is bad enough. I don't need 2. Now they are using 'wireless' phone numbers with no other ID. Great!

Call blocker might be of some help.  There's no way to stop the calls from being initiated.

I have call blocker. I block every time they call. Problem is they change numbers daily so you can't get ahead of them. I have been through 2 blockers already which fill up within a year. This is the definition of insanity.
