Caller ID showed "Buckeystown MD." Robotic female voice said "Hello we have been trying to reach you. The IRS is filing lawsuit against you..." at which point I realized it's a popular current scam and hung up.
Received a robatic call (female generated computer voice) telling me IRS has filed a law suit against me and to call 240-436-2753 immediately, January 20, 2016. Did not call back because I did not receive an official letter from the Department of IRS USA notifying same. SCAM ALERT!!!
A robotic message left on my answering machinte: Call 240 436-2753 regarding a law suit against you. Caller ID did not identify name of caller - just the phone number.
