Call came in on our landline at 241P CDT, Caller ID showed "Invalid Number" and they left no voicemail. The 469-898 NPA-NXX is an Inactive number group, not assigned to any legitimate telephone or wireless company, so this is most likely a "Spoofed" number.
Agreed with R above - recorded message that included in part "free duct cleaning and furnace inspection." Since it's a robocall the message started before the answering machine greeting ended so I missed the first part of the message. Appropriately, caller ID reads "Invalid number".
