See, for me, if you call me and don’t leave a voicemail, I’m going to assume it was unimportant (or spam) and I won’t call back. Businesses, which are most likely going to an unknown number, should leave a voicemail if they want any action on my part. I mostly don’t want businesses texting me because they tend to spam the fuck out of you.

Recently, I’ve been getting calls I’m pretty sure are spam. They are all from different numbers, but all of the area codes are from where I got my phone number, which is quite far from where I live now. Additionally, they all do leave voicemails, but each and every one is exactly thirty seconds of silence.

Spam or not, I can’t figure out the point.

Probably a bot waiting for a voice in order to start. It waits until it hangs up.

That makes sense, and I appreciate the information.

You’d think they would have marked me as inactive by now - they’ve been calling every day or two, including weekends, for more than a month. I haven’t answered once! The persistence is the only thing that made me question whether it was spam.
