Who called from 8304760060

Same as previous reporter - called and hung up. It's obviously some kind of parasite, but I'm unable to determine what.

Same as above: called my cell # and hung up.

The called me, did not say anything at all when I answered.  When they heard me say " hello" they hung up.

I did not pick up and they did not leave a message.
