LDB ENTER on caller ID. I checked the number and there is "no match" for this number: 520-230-8535. No one/message.
Been getting several calls from area codes with no matching numbers. Very irritating.
When I recognize the number I will pick up/hang up.
A call back to this number gives the following recording: "Thank you for calling, all of our operators are currently busy. If you'd like to be added to our do not call list, please press one. If you'd like to add a different number, please press two". Then it repeats again and again.
