My husband got an unsolicited call on our unlisted home cell phone number from "Jason" wanting to know if my husband was the homeowner and if he had a "security system."
When my husband asked him what kind of security system he had; he hung up.
I wonder if he is the same "Jason" from "GE Security" with various phone numbers (Google it.).
My ID caller shows only random letter, numbers and phone number. They don't want you to find out who they are. This is My Security System don't answer it.
