Get a one-ring call? Don’t call back.

A while back, we warned you about the “one ring” scam. That’s when you get a phone call from a number you don’t know, and the call stops after just one ring. The scammer is hoping you’ll call back, because it’s really an international toll number and will appear as a charge on your phone bill — with most of the money going to the scammer. Well, the scam is back with a vengeance, and the FCC just issued a new advisoryabout it. Read the FCC’s advisory for more detail, but the advice from both agencies remains the same if you get one of these calls:

• Don’t call back
• Report the robocall to the FTC at www.donotcall.gov and to the FCC at www.fcc.gov/complaints
• Always check your phone bill for suspicious or unusual charges
