I have something scheduled at 11am PT, so might not be able to get to the turn to chat at the office hour, sending it here in case: 1) One out of five times, upon initialization (after it speaks the first message), it doesn't listen to / recognize the customer's voice. This one degrades the customer experience severely and is a blocker for our contract. 2) When enableEndCall is enabled, it usually does not send back the end call signal. This one we have ways to mitigate. (someone brought this up just now in office hour)
