JTAPI Event Indicating That Call Was Not Answered

[Bliss]

Hello.

I need to detect the following scenarios in a stateless system, ideally - through a single JTAPI event:

1. Caller has hung-up before getting answered (i.e. while phone was Alerting/ringing).
2. Call was auto hung-up due to an expired timer (i.e. call was not answered for a long period of time).

Is there a distinct indication to these scenarios in any JTAPI event(s), possibly by the value of its Reason or CallCtlCause fields, etc.?

I suspect it would be possible to infer those scenarios from JTAPI events/cause/reasons, however I don't have a good source on exactly what those might be, other than to suggest trying the scenarios and looking at the results to see if you can spot the specific tells...
