Great writeup! For VAD did you use heaphone/mic combo, or an open mic? If open, how did you deal with the agent interupting itself?

I was using Twilio, and as far as I'm aware they handle any echos that may arise. I'm actually not sure where in the telephony stack this is handled, but I didn't see any issues or have to solve this problem myself luckily.
