Who called from 7044452435

Tried to sell home security system

Message was left on my answering machine. "This is John. I'm a medical alert fitness specialist. Can you hear me?"

I received a call from this number. I answered but caller did not speak.

These folks keep calling ... and, not knowing who they are I let the call ring through to voice mail.  No message has ever been left for a return call.  Only "Jerks" call and leave no message for a return call.  Must be a telemarketer.

Caller ID from cherryville. No message. No business or contacts in cherryville.
