I'm working on a requirement for a customer, and I need to find calls in the call log where the recording duration is > 60 seconds. Within the call record, I see the property "duration", which pertains to the entire call. The problem is that sometimes my client's customers opt-out of the recording, and so the recording length is around 10-12 seconds, even though the actual call duration (indicated by the duration property) is anywhere from 45 minutes to 1 hour.

Is there any way that I can obtain the duration of the recording from either the call record, or from the recording info record? Or, alternatively, is there a way that I can see if the caller "opted out" of the recording?
