The caller left a message stating  i owe IRS money and i  should call him  2064364911

Warrant for my hubby's arrest and to call ASAP.... 206-436-4911 he had clearly used a voice alteration device.

Received a call from this number and was told had a outstanding arrest warrant and need to call this number immediately.

My husband would listen to the message these "shrubs" would leave on the phone, but would not return their call, his logic
was that, if they want to spent their money and keep calling the long distance, we better not interfere and respond. He thought
if we do not respond to the calls, they end up paying the phone company and run out of money..... let them be stupid!!!

Probably not these people.  They are calling from a magicJack, probably from overseas.  For about $100.00 US, they can buy one of these devices in India, get a US phone number, and use the device to call back to the US with unlimited free calling for six months to an entire year, depending on which magicJack they purchase.  See:
