Settings for the callee and caller when call recording is completed

I have a question about webhook “Call recording is completed.”
If I add a call and record the call, more than 3 people will be on the call.
In this case, what would be the settings for the callee and caller of the following object?

Hi @ryoko ,

It sounds like this is a conference call and the recording info returned may be dependent on your call recording settings.

Could you please test this and share the results along with your call recording settings?
