Sinch Answered Call Event Callback (ACE) not called
问题 I have added a Callback in Sinch portal to handle app to app calls via our server. When a call reaches the Sinch platform, the system makes a POST request to our server's calling callback URL i.e. Incoming Call Event Callback (ICE) called. In response to ICE event our server response it as { "instructions": [], "action": { "name": "connectMXP" } } and callee receive incoming call notification. When Callee pick-up call the call get connected but it doesn't request to our server's callback URL,
