"Anyone can record DTMF tones in a voicemail message and forward calls to that number." I have never used "duo" and it has taken me a few reads of this to understand exactly what this is, but I think it's worth pointing out that your own personal 'dontduo' service would be trivially simple to set up in a simple twiml bin, at twilio. I think it would look something like this: <?xml version="1.0" encoding="UTF-8"?> <Response> <play digits="1w2w3w4"></play> <Hangup /> </Response> "Include w to introduce a 0.5s pause between DTMF tones. For example, 1w2 will tell Twilio to pause 0.5s before playing DTMF tone 2. To include 1s of pause, simply add ww." https://www.twilio.com/docs/voice/twiml/play#attributes-digits https://www.twilio.com/docs/voice/twiml/play#attributes-digi...
