Who called from 8458427299

This number showed up as Emergency Alert but of course left no message

Let it ring 5 times, no one answered when I picked up; they hung up.

They called. No message on answering machine. BLOCKED!

Message stated they are calling about a medical alert.

Received a call from 845-842-7299.  US Search said it was not a valid number.  Web Services was listed on my Phone ID.  They left no message, but I am receiving a lot of computer type phone calls.  Need more info.  Thanks
