This number left a message that sounded like an automated voice saying that our IP address may have been breached which means the internet line may be disconnected within 24 hours. It doesn't identify where it is from. It says to press '1' to talk to a technical team. Naturally we did not press 1 as this seems like a scam. Does anybody have any further information about what or who this is?

Rings but doesn't leave messages. Anyone know who it is?
