WiFi and VoLTE calls - Wifi data or call minutes?

[Gandalf2]

If I make Wifi or VoLTE calls on my Samsung S8 (with a Telstra SIM) while connected to a WiFi site (in my case an Optus Home Mobile Broadband Wifi AP), are my calls charged to Optus data or to Telstra call minutes?

Thanks

If you use WiFi the data used is charged to optus service and the call minutes to your Telstra service.

If you use Volte data is unmetered but the call minutes will be charged to Telstra Service.
