I'm currently working on an automated voice call interpreter. I know that it's not currently possible to gather digits during a conference call directly. That's why I had to come up with a workaround and let twilio dial into the conference call, so that I can gather the participants digits. It works great but the problem is that it's costing me around 4.2c per minute, which of course is not ideal at all.
Is this feature currently on your to do list and if yes, when are you going to make it publicly available?
Cheers, Marcel
