I've had two calls from this number now, and both times there's been nothing but silence on the other end. I'm beginning to think it might be some sort of scam.

I answered the call, but there was silence on the other end before it cut off. Seems like it could be one of those voice-activated setups. We have a rule to stay quiet and let them kick off the chat, but more often than not, it stays silent, and that's when we just block the number.
