TwiML App: If the caller hangs up in the middle of the application process, does Twilio notify the app of a hang up?
问题 I am trying to figure out a way to capture if the caller hangs up in the middle of TwiML instructions. If the caller hangs up (abandons the call) does twilio notify the application of such? I see the status callback url setting but I just get a "completed" status. I was wondering if the caller was in a middle of a gather and hung up would twilio know the call hung up and report it? Or am I supposed to just see the "completed" status and at that time determine if the call actually successfully
