Do NOT answer if this number comes up on your caller ID.


Duct cleaning services. Phone rings, you  pick up, say hello. Dead air. Finally someone comes on with some unintelligible Third World accent offering blahblahblah-ductcleaning-blahblahblah.

Do NOT answer if this number comes up on your caller ID.

If you call back - the number is not in service. A spoofed caller ID. Various intelligence agencies can collect meta-data on phone calls but are unwilling to assist law abiding citizens by shutting down these thieves and criminals.
