Beware of phony IRS calls.  213-928-3148 called twice today.
Left a message on my machine from 213-928-3148, a Feminine Robot voice saying it was the IRS with a final message that they were suing me - to call immediately ... etc...

I did not - but I'm sure people do - DO NOT PROVIDE ANY INFORMATION.  I am sure the first thing they'll do is ask for name/address/SS#.
