Like I ever answer my door lol. But they can leave something in the mailbox, and I'll at least see the envelope in 1-30 days.

Last week I finally had an onslaught of spam voicemails, several in an hour, that caused me to disable voicemail notifications altogether. I'll just check them when I'm expecting something now, similar to mail. My phone app was successfully filtering the calls so I wouldn't see them, but it still got routed to voicemail which then created a notification.
