Called me this after noon, Feb 17th.  Didn't leave a message in my answering machine.  Caller ID shows "Baltimore MD".
No company name or person's name.  Must be a scam.

THIS 443-992-4913 NUMBER CALLS MY CELL PHONE EVERYDAY, WHEN YOU GO TO ANSWER THERE IS NO ONE THERE, IF YOU CALL IT BACK NO ANSWER. WOULD LIKE TO SCREAM I HATE THESE PHONE CALLS AND THE DNC LIST IS A JOKE.

This 443-992-4913 has called this week on 2/16/15 at 11:01 a.m., 2/17/15 at 1:51 p.m., 2/19/15 at 12:17 p.m., and 2/20/15 at 2:47 p.m.  Caller ID reads "Baltimore MD".  Each time they let the phone ring 3 maybe 4 times.  No message is left.

keep calling and when call back no answer just hang up

Received a call from 443-992-4913 on Feb. 23rd.  Shows up on caller id as Baltimore,  Maryland.   Called at 2:31pm.  When I answer, there is no response.   When calling the number back, no one answers.  Something REALLY needs to be done about these phone calls!  It seems that if we have the number, the number can be traced to the owner and the victim could be outed!!!  SICK AND TIRED OF THESE TYPE PHONE CALLS!!!!
