Who called from 9513813107

same as above

Same as everyone else.  I blocked it before they could hang up on me.  Thanks for the info, everyone.

Continuing to call everyday!

Same here, answered, only silence until a loud screetch, then hung up.

Unknown call - we never answer unknown calls - no CID - no message.  We have the entire 951 area blocked - our phones do not ring when any call comes in from the 951 area code.
