Why is time after external transfer included in handle time?

doesn't make sense for ringcentral to track the duration of a call that has left their system.
you have 3 parties in your case.
1. person who transfers (we can infer this is internal person/sb in your company)
2. person who is transferred
3. recipient of transfer

if both 2 and 3 are external people, you shouldnt be able to see the live talk after transfer. However I am not 100% confident and will try to reproduce this scenario on my end and see what I get
