These calls are likely spam, and they show classic patterns of bulk VOIP scams. The caller reuses old number blocks and a single service provider, which is a hallmark of automated robocall operations that rent numbers cheaply. You’ll often hear vague pitches about rentals or purchases, but the goal is usually to harvest personal info or push fraudulent offers. Hang up immediately, block the number through your carrier or phone’s built‑in features, and consider registering with the national Do‑Not‑Call list. If you suspect a scam, report it to the FTC or your telecom provider for further action.
The same caller has been reaching out for years from the same region, selling rentals and purchases, using blocks of old numbers from the same provider via VoIP.
