Who called from 6105084031

Calls repeatedly but leaves no message on answering machine and/or won't talk even if I answer the call.  Security?  Just trying to find out if I'm home?

Thanks for heads up on spam

Received a call 12:00'. Did not answer..

CID only showed Allentown, PA.  No message left.  Makes me want to end my phone service.

Called several times.  Does not speak when I answer.
