Caller type: Unknown
I don't answer these calls and they all are identified as SSI. After a long silence a female voice asks if I'm there (using my name no less), and keeps asking if I'm on the line. The voice of the person sounds foreign and there is a lot of background noise, like in a call center. I always ignore the calls or hang up on them. They started four days ago and I'm getting them at least 3 times a day.
