Twilio's also great because I can set it up to answer known 2FA voice calls and hit the # button automatically to confirm.
I also use it to play endless loops of hold music for unscheduled calls to teach businesses to stop calling me without making an appointment and e-mail me instead.
I feel ya. I have a public line that does the same thing, but instead if you call or text it just lets you know that I'll contact them, not the other way around.
Question: why do you not terminate the call? Do you not get charged for the usage if you make them hold?
It's only something like $0.0085/min. On their end though if someone stays on hold for 15 minutes it wastes the company's 15 minutes worth of that person's salary time and they learn to not do it again.
Nothing beats a confused, talkative old man, when it comes to wasting a caller's time.
I'm sure you could adapt the files / logic.

Yet another Voip.ms customer here - I can only guess that's voicemail transcription, a feature I've been using (and evangelizing) for months now. Every message is transcribed and emailed to me, with a confidence level of accuracy, and even the original audio so I can verify or listen myself.
Considering how many features they've rolled out, I can only imagine how easy it could be to miss though.
