It looks like you’re getting a classic ping call—a silent ring that drops when you pick up. These are usually automated systems testing numbers for future scams or telemarketing lists. Since there’s no voice and the line disconnects, it’s safest to let it go to voicemail and block the number if it keeps popping up. Never call back, especially if you don’t recognize the caller, because you could be feeding a legit‑looking number to scammers. Keep an eye on your carrier’s spam‑filter settings and consider a third‑party call‑blocking app for extra protection.
There was no audio when the call was answered, and no response when it was called back.
