Changes to Voice Insights Advanced Features Billing for some call flows

In some cases calls placed using the Conference Add Participant API, <Refer>, and <Dial><Sip> Multidial are not being properly billed for Voice Insights Advanced Features usage. We’ll be introducing a fix for new accounts created after February 24, 2021 that will result in these call flows being billed properly. The billing behavior will not change on existing accounts.
