I received a call from 714-201-7276 (caller id) on 11/20/14. The message indicated they "have been trying to reach me and this is final notice that the IRS (pre-recorded name) is filing lawsuit against me. The callback number is 206-801-1804. I attempted to call this number and it just keeps ringing. I then tried to call the original number and received a recording that this number is no longer in service. This has got to be a spam.
