Start by finding the call_UUID of each participant of the conference call in order to begin the debugging process. To find the call_UUID, take one of these steps.
Checking your account dashboard logs
Log in to your Plivo dashboard from https://console.plivo.com/dashboard/ and navigate to https://console.plivo.com/voice/logs/calls/. Then, click on the timestamp of the relevant call which you want to debug. This will give you the call_UUID.
Use the get all call details API
This API will give you the call_UUID: https://www.plivo.com/docs/api/call/#get-all-call-details
Use this API by making a GET HTTP request to the call detail records (CDRs). This will lead to information about your calls, along with details about each call.
After getting the call_UUID, navigate to https://console.plivo.com/voice/logs/debug/?next_id=&page=1&type=all and input the call_UUID in the search field. This will surface call details such as:
Alternately, check the XML document that is used on the call to handle the call flow. This will also help you debug the call from your end.
