Maybe, but there's no human behind that initial phone call. If it can redial once a second, I guess you're slowing them down by 30x by staying on the line for 30 seconds - but I'd wager that they're making enough money that even by having to spin up 30x more resources to auto-dial, it's still a profitable business. fwiw, I have my phone set to ignore "likely spam" calls, and to not notify me about new voicemails with a vibration. There's a non-zero chance I'll miss an important call about my child, but 99% of these calls originate from an area code we no longer live in, so the trade-off seems acceptable to me - and I check whether I have _legitimate_ voicemail every few hours or so in a tab on my laptop.
