Called me (on our business number) and I answered and said my name and business name. The phone call just got disconnected (from their end). When I tried to call back, just heard an automatic message saying "your call couldn't be connected". Just blocked them.

Spam or scam caller

I responded, siaf hello, nothing else, maybe trying to record voice for deepfake voice manipulation?

Why do they spam call
